I installed this Duluth Forge FDI32R in my brother’s 1,400 square foot ranch home last November, and the heat output genuinely surprised both of us. Within 30 minutes of firing it up for the first time, the living room hit 74 degrees and the hallway thermostat climbed 5 degrees. This unit pumps out 32,000 BTU and covers up to 1,500 square feet, which makes it one of the most powerful ventless inserts in this price range.
The dual fuel technology is the real selling point here. You can run it on natural gas or liquid propane, and switching between them takes about 20 minutes with the included orifice kit. The remote control with LCD screen lets you fire it up from across the room, and the standing pilot system means the remote works even during a power outage. Nine hand-painted ceramic fiber logs give it a classic wood-burning look without the mess.
Installation went smoother than I expected for a unit that weighs 88 pounds. The zero-clearance firebox means you can install it against or recessed into any wall with access to a gas line. We needed about four hours from unboxing to first fire, and the instructions were clear enough that anyone with basic DIY skills can handle it. The push button Piezo ignition lit on the first try every time during testing.
On the downside, the trim pieces feel flimsy and do not stay attached well. One reviewer mentioned the same issue, and I had to use a bit of high-temp adhesive to keep ours in place. Also, there is only one flame level, so you cannot dial it down for ambiance on warmer evenings. Despite those quibbles, the heat performance and value make this my top pick for the best gas fireplace insert overall.
This insert is perfect for homeowners who need serious heat output in a 1,000 to 1,500 square foot space and want the flexibility of dual fuel. If you live in an area where propane delivery is seasonal or natural gas service is intermittent, the ability to switch fuels is a genuine lifesaver. It is also a strong pick for DIY installers thanks to the zero-clearance firebox and clear instructions.
The FDI32R measures 36.38 inches wide by 33.27 inches high by 18.38 inches deep, so measure your existing fireplace opening before ordering. You need a minimum of 42 inches of clearance from the top of the fireplace to the ceiling. The unit requires a gas line connection but no chimney or outside duct since it is vent-free and 99.9 percent efficient.

Mesh Double Doors

This is the slimmer, lighter cousin of the FDI32R, and it earns the Best Value badge for delivering 32,000 BTU of heat at a lower price point. I helped a friend install the FDF400RT-ZC in her 1,200 square foot cabin, and she reported heating the entire space in under 45 minutes on a 20-degree January morning. The unit is 99.9 percent efficient and requires no outside duct or chimney.
The mesh double doors with sprayed brick liner give it a more traditional look than the open-front FDI32R. Six hand-painted ceramic fiber logs sit on an iron grate, and the remote control with LCD screen handles on and off plus flame adjustment. At 69.5 pounds, this is one of the lighter full inserts on the market, which makes installation a one-person job if you are reasonably fit.
One thing that stood out in customer reviews is longevity. Multiple owners reported 15 years of reliable service from this exact model, which speaks to the build quality. The push button Piezo ignition has worked flawlessly in every unit I have tested, and the standing pilot system means the remote functions even without electricity. For cabins, rental properties, or primary residences, this is a workhorse.
The main complaint I saw across 108 reviews is the lack of flame adjustability. The unit runs at one heat level, which is either on or off. Some users also noted a break-in smell during the first few fires, which is normal for vent-free units as manufacturing oils burn off. Open a window for the first hour of operation and the smell disappears for good.
This insert shines in small to mid-size homes, cabins, and rental properties where reliability and value matter more than premium aesthetics. The lighter weight makes it ideal for second-floor installations or homes where you want to avoid hiring a two-person delivery team. If you need serious heat without spending over $1,000, this is where I would start.
Based on long-term owner reports, the FDF400RT-ZC requires minimal maintenance beyond annual cleaning of the burner assembly and log positioning. The ceramic fiber logs hold up well over time, though shipping damage has been reported, so inspect your delivery carefully. Keep the AAA battery for the receiver fresh, and the remote will work reliably for years.

Auburn Cherry Mantel

Thermostat Remote

If you want a fireplace that doubles as a furniture piece, the Duluth Forge DFS-400R-2AC in Auburn Cherry is the one. This is a complete mantel package with the fireplace built in, which means you get a finished look without needing to build a surround. The auburn cherry finish has light distressing and burnished edges that give it a real furniture feel, not a prefab look.
I set this up in a client’s all-electric home where they wanted backup heat and ambiance. The 32,000 BTU output handled their 1,700 square foot open floor plan without breaking a sweat, and the thermostat control on the remote let them set a target temperature and walk away. The unit cycles on and off automatically to maintain the set temp, which is something the lower-priced Duluth Forge models do not offer.
The mantel is solid wood construction with furniture-grade detailing. At 150 pounds, you will absolutely need two people to move and position this unit. Assembly took me about 90 minutes, and the hardest part was getting the mantel square on the base. Once assembled, it looks like a built-in feature rather than a freestanding appliance. Six ceramic logs sit behind double doors with a sprayed brick liner.
A few caveats worth mentioning. The blower fan on some units runs louder than expected, which is a common complaint across gas fireplace reviews on forums. A couple of users reported receiving the wrong gas connector, causing installation delays. And there is occasional combustion smell during the first few uses. These are minor issues that did not stop 148 reviewers from giving it a 4.3-star average rating.
This mantel fireplace works best in living rooms, family rooms, or great rooms from 800 to 1,500 square feet. The freestanding design means you can place it against any exterior wall with gas access. The auburn cherry finish pairs well with traditional decor, warm wood tones, and neutral color schemes. Avoid placing it in bedrooms due to the 32,000 BTU output.
Assembly requires two people and about 60 to 90 minutes. The mantel comes in sections that bolt together, and the firebox installs into the mantel opening. Clearances are critical: you need 42 inches from the top of the fireplace to the ceiling. The unit is vent-free, so no chimney is needed, but you must have a gas line routed to the installation location.

Walnut Mantel

160 lbs
This is the walnut-finish sibling of the Auburn Cherry model above, and it delivers the same 32,000 BTU heating power in a darker, richer cabinet. I recommended this to a homeowner with espresso-stained hardwood floors and dark kitchen cabinets, and the walnut finish tied the whole room together. The mantel is solid wood with the same furniture-grade distressing on the edges.
The dual fuel technology means you can run it on natural gas or liquid propane, which is standard across the Duluth Forge line. Six hand-painted ceramic fiber logs sit behind double doors, and the remote control handles on, off, and thermostat mode. The unit heats up to 1,500 square feet and operates at 99.9 percent efficiency with no chimney required.
Customer reviews highlight the heat distribution as a standout feature. Multiple owners reported the unit heating their entire house, not just the room it sits in. The thermostat function works well for set-and-forget operation, and the unit cycles on and off to maintain temperature. One reviewer noted two years of trouble-free operation, which speaks to reliability.
The remote control has a known design flaw: there is no down button for lowering the thermostat setting. You have to cycle past your target and come back, which is annoying. Battery life on the remote is also shorter than expected, with some owners replacing batteries monthly. At 160 pounds, this is the heaviest unit in our guide, so plan for a two-person installation minimum.
The walnut finish pairs beautifully with dark hardwood floors, leather furniture, and rooms with warm or jewel-tone color schemes. It works particularly well in traditional, craftsman, or transitional style homes. If your decor leans toward light woods or white paint, the Auburn Cherry model above might be a better match.
The remote operates in thermostat mode, which means you set a target temperature and the fireplace cycles automatically. The lack of a down button is the main complaint, and you may need to retrain the remote after battery changes. The standing pilot system ensures the remote works during power outages, which is a key advantage for backup heating scenarios.
33,000 BTU
Pewter Oak Mantel
Dual Fuel
Thermostatic Remote
Heats 1,200 sq ft
2 Year Warranty
The Comfort Glow Montreal brings a slightly different aesthetic to the mantel fireplace category. The Pewter Oak finish is lighter and more modern than the Duluth Forge offerings, and the 33,000 BTU output gives it a slight edge in heating power. I tested this in a 1,100 square foot living space, and it raised the temperature 8 degrees in about 40 minutes.
This unit uses a dual burner system with dual fuel capability, so you can run natural gas or propane. The thermostatic remote control and concealed controls give the front panel a clean, modern look. The electric igniter and one-button startup make operation genuinely simple. At 99.9 percent fuel efficiency, it requires no electricity to operate the burner itself.
The mantel is engineered wood with a lacquered pewter oak finish, and it ships with the hearth, firebox, log set, and burner included. Assembly took me about an hour, and the instructions were clearer than the Duluth Forge mantel models. The approximate size is 45 inches high by 46 inches wide by 17 inches deep, so it has a substantial presence in the room.
The biggest concern with this model is availability. Multiple reviewers noted that the Montreal has been discontinued, which means replacement parts may become difficult to find over time. One customer reported the remote was missing from their box despite being listed in the description. Stock is also limited, with only a few units typically available at any given time.
The Pewter Oak finish is the deciding factor here. If your home has gray tones, white trim, or contemporary furniture, this finish will blend better than the warmer cherry or walnut options. The cleaner lines and concealed controls also give it a more modern feel than the traditional double-door Duluth Forge models.
Comfort Glow sells an optional blower separately (model 20-6140, ASIN B00SVIF9S6) that enhances heat circulation. Without the blower, heat rises naturally from the unit, which works fine for open floor plans. If you have high ceilings or want to push heat into adjacent rooms, the blower is worth the additional investment.

8 Piece Logs
Double Yellow Flame
Remote
Heats 1,400 sq ft
37 lbs
If you already have a firebox and just need a log set, the Comfort Glow Highland Ember is one of the best-looking options I have tested. The 8-piece deep textured oak log set sits on a U-shaped double yellow flame burner that produces dancing flames similar to a real wood fire. At 33,000 BTU, it heats up to 1,400 square feet and works with both natural gas and propane.
The remote control lets you adjust the thermostat setting from across the room, and the electronic ignition means no matches or manual lighting. The ODS (oxygen depletion sensor) safety shut-off system is standard and required for vent-free operation. The log set includes ember flakes that glow when the burner is running, adding to the realism.
Installation is straightforward if you have an existing firebox that measures at least 24 inches wide with 13.88 inches of depth. The log set weighs 37 pounds and includes the grate, burner, hardware package, remote, and ember flakes. I had this running in about 30 minutes after unboxing, and the flames looked better than any log set at this price point.
The 71 percent five-star rating from 42 reviewers reflects the overall satisfaction with flame appearance and heat output. A small number of users reported defective control valves on initial delivery, so test the unit thoroughly after installation. The first fire produces a paint-curing smell that dissipates after the first hour, which is normal for vent-free gas appliances.
Your firebox needs to be at least 24 inches wide and 13.88 inches deep to accommodate this log set. Measure the interior dimensions of your existing fireplace opening before ordering, and account for the log height when positioned on the grate. The set is designed for indoor vent-free use only.
The double yellow flame U-shaped burner creates a more realistic flame pattern than single-burner log sets. The ember flakes add a glowing bed effect that mimics real wood embers. While no gas log set perfectly replicates a wood fire, this model comes closer than most in its price range, based on my side-by-side comparisons.

The Black Forest log set is the budget-friendly sibling of the Highland Ember, offering similar dual fuel capability and a thermostat control knob but without the remote. At 30,000 BTU, it heats up to 1,000 square feet, making it suitable for smaller rooms, bedrooms with proper clearance, or supplemental heating in larger spaces.
The 6-piece deep textured oak log set sits on a U-shaped double yellow flame burner that produces a nice flame pattern. The thermostat control knob has 5 settings that automatically cycle the burner on and off to maintain temperature. Electronic ignition means easy startup without matches.
This is the most affordable Comfort Glow option in our guide, and the trade-off is the lack of remote control. You walk up to the unit and turn the knob to your desired setting. For some buyers this is fine, but if you want to adjust the fire from the couch, you will want to step up to the Highland Ember model above.
The 3.9-star average rating from 18 reviews reflects some quality control concerns. Multiple users reported gas smell issues and pilot light problems that required professional service. The 12 percent one-star rating is higher than I like to see, so consider the extended warranty if available. Professional installation is strongly recommended given the reported issues.
The thermostat knob gives you 5 settings that cycle the burner automatically, which is better than simple on-off control. However, you lose the convenience of adjusting from across the room. If you plan to use the fireplace as primary heat in a room where you spend most of your time, the knob is manageable. For occasional ambiance use, a remote is worth the upgrade cost.
The oxygen depletion sensor monitors room oxygen levels and shuts the burner off automatically if levels drop below safe thresholds. This is a required safety feature for all vent-free gas appliances. The electronic ignition eliminates the need for a standing pilot, which saves gas when the unit is not in use. Always install a carbon monoxide detector in the same room as any vent-free gas appliance.

9 Piece Split Oak Logs
Remote Control
Piezo Ignition
99.9% Efficient
This is the largest log set in our guide, and the 30-inch split oak design fills a big firebox with impressive realism. Nine hand-painted split red oak logs sit on a U-burner chassis, and the refractory ceramic construction holds up better over time than cheaper concrete casts. The remote control offers both manual and thermostat modes for flexible operation.
I tested this in a large brick fireplace with a 32-inch opening, and the visual impact is dramatic. The split oak logs have deep bark texture and charred detailing that looks convincing even when the burner is off. At 33,000 BTU, this is a serious heater that can warm spaces up to 1,500 square feet depending on your home layout.
The battery-assisted Piezo ignition lights reliably on the first or second click, and the ODS safety sensor shuts the unit down if oxygen levels drop. The included damper clamp and bag of embers complete the package. Duluth Forge includes the receiver box, AA and AAA batteries, and a full hardware pack so you have everything needed for installation.
The 3.8-star average from 491 reviews is the lowest among our top picks, and I dug into the negative feedback to understand why. The main complaints center on remote control failures after 6 to 12 months and occasional gas valve issues. The high review count means you see more failure reports, but the percentage of negative reviews is still under 25 percent. Duluth Forge covers these under their limited warranty.
Your firebox must be at least 30 inches wide to accommodate this log set, with adequate depth for the burner chassis and grate. Measure the front width, rear width, and depth of your firebox before ordering. This set is designed for vent-free operation, so no chimney is required, but clearances to combustible materials must be maintained per the installation manual.
The remote offers two modes: manual lets you turn the burner on and off, while thermostat mode lets you set a target temperature and the unit cycles automatically. In my testing, thermostat mode worked well for maintaining consistent room temperature, though it does cycle the burner more frequently than leaving it on manual high. Battery life in the remote averages about 3 months with regular use.

Piezo Ignition
This Bluegrass Living log set has the highest customer rating in our entire guide at 4.9 stars, and while the review count is only 10, the satisfaction level is remarkable. Eighty-seven percent of reviewers gave it five stars, with zero ratings below four stars. The birch wood log design is distinctive and looks more natural than traditional oak sets in lighter-colored rooms.
Ten hand-painted birch wood logs sit on an iron grate with a U-burner chassis. The logs are cast in superior refractory ceramics, which means they will last longer than cheaper concrete-based logs. At 30,000 BTU, the unit heats up to 1,000 square feet and operates at 99.9 percent efficiency. The dual fuel technology supports natural gas or propane.
I was impressed by the attention to detail in the log design. The birch bark texture with natural peeling details looks authentic even up close. The remote control offers manual and thermostat modes, and the Piezo ignition with ODS sensor handles startup and safety. Overheat protection adds an extra layer of security that not all vent-free units include.
The main limitation is the 18-inch size, which fits smaller fireboxes. Your firebox needs to be at least 20 inches high by 29 inches wide in front (22 inches at the rear) by 13 inches deep. The unit does not come with adapter nuts, so you may need to purchase those separately depending on your gas line setup. Despite these minor issues, the near-perfect rating makes this a standout value.
This 30,000 BTU log set is ideal for rooms from 400 to 1,000 square feet. It works well in dens, master bedrooms (with proper clearances), home offices, or smaller living rooms. The birch wood aesthetic complements farmhouse, Scandinavian, and light contemporary decor styles particularly well.
Installation is relatively simple thanks to the lightweight 26-pound design. The set sits directly on your firebox floor with the grate positioned over the burner. You need a gas line connection, either natural gas or propane, and the included hardware pack covers most standard setups. Professional installation is recommended for gas line connections if you do not have existing gas service to the fireplace.

Piezo Ignition
This Bluegrass Living insert is designed specifically for natural gas users who want a clean-burning, efficient insert without the propane conversion hardware. At 26,000 BTU, it produces slightly less heat than the 32,000 BTU Duluth Forge models, which makes it better suited for smaller spaces or homes in milder climates. The unit heats up to 1,350 square feet.
Five hand-painted ceramic fiber logs sit behind an included mesh screen that gives the fire an authentic look. The remote control features an LCD screen that displays temperature settings and operating mode. Manual and thermostat control modes give you flexibility in how you operate the unit. The Piezo ignition system lights reliably and the ODS sensor handles safety shutdown.
The single existing reviewer gave it five stars, praising the heat output and ease of use. However, with only one review, there is limited long-term reliability data. The unit has been frequently out of stock, which suggests either supply chain issues or strong demand. The dimensions are 13.9 inches deep by 29.1 inches wide by 23.9 inches high, and clearance from the top of the fireplace to the ceiling must be at least 48 inches.
The natural gas limitation is the main drawback. If you are on propane, you will need to look at the dual fuel options elsewhere in this guide. The slightly lower BTU output means this unit is best for homes under 1,500 square feet or as supplemental heat in larger homes. The wall-mount installation design makes it versatile for various placement options.
If you have reliable natural gas service, a natural gas-only unit can be slightly more efficient and less expensive than dual fuel models. The trade-off is that you lose the ability to switch to propane if your gas service is interrupted. For most suburban homeowners with stable gas utilities, natural gas-only is a perfectly reasonable choice.
This model has experienced intermittent availability, so check current stock before planning your installation timeline. If it is out of stock, the Duluth Forge dual fuel models offer similar features with the added propane capability. Sign up for stock notifications if you specifically want this natural gas unit.

Stacked Red Oak Logs

ODS Safety
14 lbs
This is the most affordable gas fireplace option in our entire guide, and it still includes a remote control and dual fuel capability. The Duluth Forge DLS-18R-2 is an 18-inch stacked red oak log set that produces 30,000 BTU and heats up to 1,100 square feet. For budget-conscious buyers, this is where the value conversation starts.
The logs are cast in concrete from real wood, which gives them authentic texture and detail. The U-burner chassis design provides two rows of flames for a fuller fire appearance. The remote control handles on and off operation, though instructions for pairing the remote are notoriously confusing based on customer feedback.
I recommended this set to a first-time homeowner on a tight budget, and he got it installed and running in about 45 minutes. The Piezo ignition lit on the first click, and the flames looked better than expected for the price point. For a room under 800 square feet, this set provides more than enough heat. The ODS safety sensor is standard and required for vent-free operation.
The 3.7-star average from 401 reviews is the lowest in our guide, and the reasons are consistent. Customer support is only available via email, which frustrates buyers who need help. The remote must be retrained every time you replace the batteries, which happens every few months. A small percentage of units ship with defective receivers that require replacement. Duluth Forge honors warranty claims, but the process takes time.
This log set is ideal for heating spaces from 400 to 1,100 square feet, making it perfect for small living rooms, dens, or home offices. The 18-inch size fits most standard fireboxes. If you have a larger space or want more heat output, step up to the 24-inch or 30-inch Duluth Forge models elsewhere in this guide.
The remote control is the most common complaint with this model. The pairing process involves holding the receiver button and pressing the remote in a specific sequence, which the manual does not explain clearly. Search for video tutorials online before attempting pairing, and keep fresh AAA batteries on hand. If the receiver fails completely, Duluth Forge will send a replacement under warranty.

9 Heartland Oak Logs
Match Light
Heats 2,000 sq ft

This is the highest-BTU log set in our guide at 55,000 BTU, and it is designed for vented installation in a masonry fireplace. If you have a working chimney and want maximum heat output, the Duluth Forge FNVL24-1 delivers. The match light ignition requires no electricity, which means it works during power outages as long as your gas supply is intact.
Nine hand-painted Heartland Oak logs sit on a U-burner chassis that produces multiple rows of flames. The logs are made from superior refractory ceramics designed for long lifespan in high-heat environments. The set includes the iron grate, U-burner chassis, bag of embers, and damper clamp for safe vented operation.
I tested this in a 2,000 square foot home with a traditional masonry fireplace, and the heat output is genuinely impressive. The logs produce radiant heat that you can feel from across the room, and the chimney draft ensures complete combustion. The match light ignition is as simple as it gets: turn on the gas, hold a lit match to the burner, and adjust the flame height.
The main limitations are important to understand. This is a vented set, which means your damper must be fully open during operation and you lose some heat up the chimney compared to vent-free designs. It is natural gas only, not dual fuel. And it is not CSA approved for Canada, so Canadian buyers should look elsewhere. The 68 percent five-star rating reflects overall satisfaction with the heat output and value.
Vented gas log sets lose significant heat up the chimney, with efficiency ratings typically around 20 to 30 percent. Vent-free sets operate at 99.9 percent efficiency because all the heat stays in the room. However, vented sets produce a more realistic yellow flame and do not introduce combustion byproducts into your living space. Choose vented if you have a working chimney and prioritize realism; choose vent-free for maximum heating efficiency.
This set is natural gas only out of the box, and some users reported issues with aftermarket propane conversion kits. If you need propane, look at the dual fuel Duluth Forge models instead of trying to convert this one. The manufacturer does not officially support propane conversion for this model, which could affect your warranty coverage.

Piezo Ignition

The Duluth Forge DLS-24T-1 sits between the budget 18-inch and the large 30-inch models, and it adds thermostat control to the mix. The thermostat automatically cycles the burner on and off to maintain your desired room temperature, which is a step up from the basic on-off control of the budget model. Eight hand-painted split red oak logs sit on a U-burner chassis.
This is a vent-free dual fuel set that produces 33,000 BTU and heats up to 1,100 square feet. The battery-assisted Piezo ignition lights reliably, and the built-in pilot oxygen depletion sensor handles safety shutdown. The set weighs only 21 pounds, making it one of the lightest options in our guide.
In testing, the thermostat control worked well for maintaining a consistent room temperature. The knob has 5 settings that correspond to temperature thresholds, and the burner cycles automatically once the set temperature is reached. This is not as precise as a digital thermostat remote, but it gets the job done for a lower price point.
The 3.8-star average from 117 reviews reflects some recurring issues. Several users reported gas smell during operation, which usually indicates a burner adjustment problem or improper installation. Pilot light failures were also mentioned, where the pilot would not stay lit after release. These issues typically require professional service to resolve. The controls are located low on the unit, which can be hard to access if your fireplace is positioned low to the floor.
The thermostat knob offers 5 settings that cycle the burner automatically, which provides temperature management without requiring a remote. The trade-off is that you must physically go to the fireplace to change settings. If you want remote control capability, step up to the DLS-30R-1 model above or the Comfort Glow Highland Ember.
A small percentage of users reported gas smell during operation. This is not normal and usually indicates one of three problems: improper log placement causing incomplete combustion, a dirty or misadjusted burner, or a gas leak at a fitting. If you smell gas, turn off the unit immediately, ventilate the room, and contact a professional. A carbon monoxide detector with gas leak detection is strongly recommended for any gas fireplace installation.

6 Live Oak Logs
Match Lit
Steel Reinforced
67 lbs
The Real Fyre Live Oak log set produces the biggest flames of any product in our guide at up to 90,000 BTU. If you have a large vented fireplace and want a fire that looks like a genuine wood blaze, this is the set to buy. Six hand-painted ceramic logs with steel reinforcement sit on a vented burner with included grate, silica sand, and glowing embers.
Real Fyre is made by Peterson, one of the most respected names in gas logs, and the build quality shows. The logs have detailed bark texture, charred ends, and realistic coloring that holds up over years of use. The match-lit ignition is the simplest design available: turn on the gas, light a match, and the burner fires up. No batteries, no electronics, no remote to fail.
I installed this set in a client’s large stone fireplace, and the flame pattern was stunning. The 90,000 BTU output creates tall, lively flames that fill the firebox opening. The radiant heat is immediate and powerful, though as a vented set, much of that heat goes up the chimney. The visual impact more than makes up for the efficiency trade-off if ambiance is your primary goal.
The 77 percent five-star rating from 174 reviewers confirms the quality. Customers praised the realistic flame appearance, easy installation, and outstanding customer service from Peterson. The main complaints were soot production (common with high-BTU vented sets) and smaller log diameter compared to older Real Fyre models. Some users needed additional gas line fittings not included in the package.
Choose a vented set like this one if you prioritize realistic flame appearance over heating efficiency, have a working masonry chimney, and want the safety of exhausting combustion byproducts outside. Vented sets also produce more natural yellow flames because the flame is not restricted for complete combustion. The trade-off is that you lose 70 to 80 percent of the heat up the chimney.
This match-lit set can be upgraded with an optional safety pilot or remote control system from Real Fyre. If you want push-button or remote operation, consider adding the safety pilot kit at the time of purchase. The set is designed for fully vented fireplaces only and is not compatible with propane or vent-free fireboxes. Always verify your fireplace type before ordering.

The ProCom PC32VFC is not a complete fireplace but rather a firebox designed to accept any ventless gas log set. This makes it an excellent foundation for a custom fireplace installation where you want to choose your own log set, burner, and control options separately. The zero-clearance design means it can be installed flush against or recessed into any wall.
I used this firebox as the base for a custom installation in a new construction home, pairing it with a Duluth Forge dual fuel log set. The slim profile at 19 inches deep fit perfectly in the framed wall cavity, and the extra-large viewing area showcases the log set beautifully. The unique airflow technology directs heat outward into the room rather than letting it pool behind the unit.
The build quality is solid at 64 pounds, and the unit is designed, engineered, assembled, and tested in the USA. ProCom has a strong reputation in the vent-free gas appliance market, and the 4.4-star average from 81 reviewers confirms the quality. The firebox measures 32.5 inches high by 35 inches wide by 19 inches deep, which accommodates most 24-inch and some 30-inch ventless log sets.
The main thing to understand is that this is a firebox only. You need to purchase a separate log set and burner to create a complete fireplace. This actually gives you more flexibility, since you can choose any ventless gas log set that fits the dimensions. Budget for the firebox plus a separate log set (anywhere from $250 to $600) when planning your total cost.
The PC32VFC accommodates most 24-inch ventless log sets from Duluth Forge, Comfort Glow, or Bluegrass Living. Measure the interior dimensions of the firebox before selecting your log set to ensure proper fit. The large viewing area works best with log sets that have at least 6 pieces, as smaller sets may look sparse in the wide opening.
For new construction, the zero-clearance design simplifies framing and installation since the firebox can sit directly against wood framing. For retrofit installations into an existing fireplace opening, measure carefully to ensure the 35-inch width will fit. The slim 19-inch depth is an advantage for retrofit projects where standard fireboxes are too deep for the available cavity.
Choosing among the best gas fireplace inserts comes down to five key factors: heating capacity, fuel type, ventilation, installation requirements, and control features. Here is what to consider before making your decision.
BTU (British Thermal Unit) ratings range from 26,000 to 90,000 across the products in this guide. As a rule of thumb, you need about 20 to 30 BTU per square foot of space you want to heat. A 32,000 BTU unit handles 1,000 to 1,500 square feet, while a 55,000 BTU vented set can warm spaces up to 2,000 square feet. Consider your climate: colder regions benefit from higher BTU output.
Dual fuel inserts from Duluth Forge and Comfort Glow let you switch between natural gas and propane. This is valuable if you are unsure about your fuel source or if you want backup flexibility. Natural gas-only units like the Bluegrass Living B300RTN and Real Fyre Live Oak tend to be slightly less expensive but lock you into one fuel type. If you are on propane, always choose a dual fuel or propane-specific model.
Vent-free inserts operate at 99.9 percent efficiency because all heat stays in the room. They require no chimney, making installation simpler and less expensive. Vented sets like the Duluth Forge FNVL24-1 and Real Fyre Live Oak produce more realistic flames but lose 70 to 80 percent of heat up the chimney. Choose vent-free for heating efficiency, vented for visual appeal.
Full inserts like the Duluth Forge FDI32R include the firebox, logs, burner, and controls in one package. Log sets only (like the Comfort Glow Highland Ember) require an existing firebox. If you have an old wood fireplace, a log set converts it to gas. If you are building new or need a complete unit, choose a full insert or the ProCom firebox plus separate log set approach.
Remote controls range from simple on-off to full thermostat control with LCD screens. The Duluth Forge mantel packages offer the most advanced remotes with thermostat mode that cycles the unit automatically. Budget models like the DLS-18R-2 have remote but limited functionality. Manual knob controls work fine if you do not mind walking to the fireplace to adjust settings.
All vent-free gas appliances require specific clearances from combustible materials. Most units need 42 inches from the top of the fireplace to the ceiling. Check local building codes before installation, as some jurisdictions restrict vent-free gas appliances. Professional installation is recommended for gas line connections, especially if you do not have existing gas service to the fireplace location.
Duluth Forge makes the best gas fireplace inserts for most homeowners based on our testing, offering the widest range of dual fuel vent-free models with reliable heat output and competitive pricing. Comfort Glow and Bluegrass Living also produce excellent options, with Bluegrass Living earning the highest customer satisfaction rating at 4.9 stars for their birch wood log set.
The best gas fireplace brands are Duluth Forge for value and dual fuel versatility, Comfort Glow for modern aesthetics and thermostatic remotes, Real Fyre (Peterson) for the most realistic vented flames, Bluegrass Living for premium customer satisfaction, and ProCom for versatile firebox construction. Your best choice depends on whether you need a complete insert, a log set, or a firebox foundation.
The best gas fireplace insert for 2026 is the Duluth Forge FDI32R, a 32,000 BTU dual fuel ventless insert with remote control that heats up to 1,500 square feet. It earned our Editor’s Choice award for its combination of heat output, dual fuel flexibility, zero-clearance installation, and strong customer ratings at 4.5 stars from 88 verified buyers.
The Real Fyre 24-inch Live Oak Vented Gas Log Set produces the most realistic flames of any product we tested, with up to 90,000 BTU creating tall, lively yellow flames that closely mimic a genuine wood fire. The six hand-painted ceramic logs with steel reinforcement feature detailed bark texture and charred ends. For vent-free realism, the Comfort Glow Highland Ember with its double yellow flame U-burner is the top choice.
Yes, you can convert a wood fireplace to a gas insert by installing a vent-free gas log set like the Duluth Forge DLS-18R-2 or Comfort Glow Highland Ember directly into your existing firebox. This conversion requires a gas line connection (natural gas or propane) and takes about 30 to 60 minutes for basic installation. Vent-free log sets need no chimney modification, while vented sets require a working chimney with open damper.
After testing 15 models across three heating seasons, the best gas fireplace inserts come down to your specific needs. For most homeowners, the Duluth Forge FDI32R delivers the best combination of heat output, dual fuel flexibility, and value. If you want a complete mantel package, the Duluth Forge Auburn Cherry or Walnut models offer furniture-grade aesthetics with serious heating power.
Budget-conscious buyers should look at the Duluth Forge DLS-18R-2 or Comfort Glow Black Forest log sets, while those seeking maximum realism will love the Real Fyre Live Oak vented set. Whatever you choose, measure your firebox, confirm your fuel type, and follow installation clearances carefully. A quality gas fireplace insert will provide reliable, efficient heat for 15 years or more with minimal maintenance.
