On this page (6 sections)
The Hongso GFK-160 is our top pick for compatible fireplaces, with dual blowers, 160 CFM airflow, pre-connected wires and adjustable air direction. For the best fireplace blower kit for your unit, match its cross-reference number, mounting space and controls before you order.
A retrofit blower moves heated air into the room, but it only helps when the fan fits the fireplace’s design. Check the model label and the old blower’s number, then measure the available space.
For more parts context, see our guide to fireplace blower motors. If your fireplace is a Heatilator, compare options in our guide to the best Heatilator fireplace blower kit.

Which fireplace blower kits fit different replacement needs?
The best fireplace blower kits here split into GFK-160, GFK4 and FK24 families, plus one longer remote controlled option. Start with the family that matches your existing part number, then compare dimensions and controls.
Hongso Pre-Wired GFK-160 GFK-160A BM-1288 Fireplace Blower: Best for pre-wired GFK-160 replacements
- Dual blower fans
- 160 CFM airflow
- Pre-connected wires
- Rheostat and thermostat
A pre-wired dual blower kit with a rheostat and thermostat for fireplaces that match its GFK-160 cross references and fit limits.
Pros
- Pre-connected wires
- 90-degree adjustable air direction
- Rheostat and thermostat included
Cons
- Does not fit Hearth and Home DV3732-B, DV3732L-B or DV4236-B
Hongso is the top pick for a compatible GFK-160 replacement because it combines 160 CFM airflow with pre-connected wiring. The dual blower fans, rheostat and thermostat make it a complete retrofit kit rather than a motor-only replacement.
Its right-angled stand allows the air direction to adjust by 90 degrees. The stated size is 12 7/8 in total length, 4 1/4 in width and 4 3/4 in bracket height, so compare all three measurements with the space behind your fireplace door.
Hongso gives cross references that include GFK-160, GFK-160A, FAB-1600 and several Heat & Glo part numbers. It also names compatible brands and models, but explicitly excludes Hearth and Home DV3732-B, DV3732L-B and DV4236-B.
Choose this kit when your existing assembly matches those cross references and you want wires already connected. Check the exact model and available clearance first, since a similar fireplace name does not confirm compatibility.
Adviace GFK-160 GFK-160A Fireplace Blower Fan Kit: Best for automatic temperature control
- 160 CFM airflow
- Magnetic automatic thermostat
- Variable speed rheostat
- 3-prong cord
This GFK-160A kit pairs a magnetic thermostat with a variable speed control and lists a broad set of Heat & Glo, Hearth & Home and Superior models.
Pros
- Thermostat turns the blower on and off as the fireplace heats and cools
- Variable speed control
- Rubber isolation feet
Cons
- Check the exact fireplace model against the compatibility details
Adviace is a close GFK-160 alternative with 160 CFM airflow, a magnetic thermostat and a variable speed rheostat. Its listed dimensions are 12 13/16 x 4 5/16 x 4 5/16 in, slightly different from the Hongso measurements.
The thermostat is described as switching the fan on and off as the fireplace heats and cools. Rubber isolation feet are included, along with a 3-prong cord, wire harness and instructions.
Its compatibility details span Heat & Glo, Hearth & Home and Superior models, among others. Because those lists are broad, use the fireplace’s full model number and compare it with the kit’s cross references before buying.
Pick Adviace if those controls and dimensions match your setup. If you want to compare more kits aimed at gas fireplaces, see our best gas fireplace blower fan kit guide.
Hiorucet GFK4B Blower Fan Kit for Heatilator: Best for Heatilator GFK4B replacements
- 130 CFM airflow
- Magnetic thermostat
- Variable speed control
- Foam mounting pads
A GFK4B style kit with foam pads, thermostat and rheostat for compatible Heatilator, Majestic, Temco and other listed fireplaces.
Pros
- Includes foam pads for mounting
- Magnetic thermostat
- Cross-references GFK4, GFK4A, GFK4B and FK4
Cons
- Lower stated airflow than the GFK-160 options
Hiorucet is aimed at the GFK4B and related FK4 family, with 130 CFM airflow and a magnetic thermostat. It includes foam pads, a variable speed control, a pre-wired harness and a 3-prong cord.
The kit measures 12.5 x 3.23 x 3.73 in. Its listed references include GFK4, GFK4A, GFK4B, FK4 and Rotom HB-RB74K, and the compatibility details name Heatilator, Majestic, Temco and other models.
The thermostat automatically controls on and off operation based on temperature. The rheostat gives manual speed adjustment, so you can set a lower fan speed when you want less airflow or noise.
Choose it when your existing part number and the fireplace model match the GFK4 family. A similar length alone does not make it interchangeable with a GFK-160 or FK24 kit.
FireplaceBlowersOnline GFK-160 Easy-to-Use Fireplace Blower Fan Kit: Best for higher stated airflow
- 180 CFM airflow
- Ball bearing blower
- Rheostat speed control
- Automatic thermostat
This GFK-160 kit has the highest stated airflow among the traditional retrofit kits here, with a speed controller and automatic thermostat.
Pros
- 180 CFM stated airflow
- Includes 2-prong adapter
- Lists Heat N Glo and Quadra Fire compatibility
Cons
- Confirm fit and wiring for your exact fireplace
FireplaceBlowersOnline’s GFK-160 kit stands out for its 180 CFM stated airflow, the highest among the traditional retrofit kits in this roundup. It includes a ball bearing blower, 3-prong power cord, 2-prong adapter, rheostat and automatic thermostat.
Its dimensions are 12.75 x 4 x 4.06 in. The brand names Heat N Glo and Quadra Fire among compatible models, but the kit’s wide fit claims still need to be checked against your fireplace model and mounting area.
The included adapter may help when the existing connection uses a 2-prong arrangement, but confirm the fireplace instructions and electrical requirements before use. This is still an AC blower kit, so compare its controls and wiring with your current setup.
Consider it when your fireplace matches the compatibility chart and you want the highest stated airflow in this group. Skip it if your required part number or available space differs.
Criditpid GFK-160A GFK-160 Fireplace Blower Fan Kit: Best for broad GFK-160 model coverage
- 160 CFM airflow
- Dual ball bearing blower
- Magnetic thermostat
- Pre-wired harness
A dual blower kit with a pre-wired harness and cross references for several Heat N Glo, Quadra-Fire and related fireplace models.
Pros
- Includes rubber mounting feet
- Thermostat and variable speed control
- Lists multiple fireplace brands
Cons
- Compare the dimensions with the available clearance before ordering
Criditpid’s GFK-160A is another 160 CFM dual blower kit with a magnetic thermostat, rheostat and rubber mounting feet. A pre-wired harness is included to simplify the connection work described for a compatible installation.
Its dimensions are 12 13/16 x 4 5/16 x 4 5/16 in. The cross references include GFK-160, GFK-160A, FAB-1600 and multiple Heat N Glo and related part numbers.
Criditpid lists Heat N Glo, Quadra-Fire, Heatilator, Superior and other fireplace models. Check both the brand and complete model number, and compare the space around the mounting area before ordering.
This is a reasonable alternative when its cross-reference and dimensions suit your fireplace. Buyers wanting a narrower GFK4 family assembly should compare the separate GFK4 options below.
Hongso GFK4 FK4 GFK4A GFK4B Fireplace Blower: Best for compact GFK4-style spaces
- 118 CFM airflow
- 12.5 in blower length
- Ball bearings
- Thermostat and rheostat
A relatively compact GFK4 style blower with ball bearings and mounting strips for compatible Heatilator, Majestic and other listed models.
Pros
- Short 3.23 in height
- Includes Velcro mounting strips
- Cross-references FK4 and GFK4 variants
Cons
- Thermostat delays startup until the blower area heats
Hongso’s GFK4 style blower is the compact choice in this group, measuring 12.5 x 3.73 x 3.23 in and stating 118 CFM airflow. It includes ball bearings, a cord, connecting wire, rheostat, thermostat and Velcro mounting strips.
Its cross references include FK4, GFK4, GFK4A and GFK4B, with examples from Heatilator and Majestic. The thermostat does not start the blower until the unit reaches about 120°F, so startup is not immediate when the fireplace is first lit.
Hongso advises comparing the original blower size before ordering. That check matters here because the blower’s stated dimensions and flange opening need to fit the available mounting area.
Choose this kit when your fireplace uses the matching GFK4 family and the compact measurements suit the compartment. For a wider selection of insert fans, see our guide to best wood stove insert fans.
AC Infinity AIRBLAZE S14: Best for remote speed adjustment
- 200 CFM airflow
- 10-speed wireless remote
- DC motor
- 15.07 in length
A longer universal style blower with a DC motor and remote speed control, for fireplaces with an underfloor or compartment space that fits.
Pros
- Highest stated airflow here
- Remote offers 10 speeds
- Lists compatibility with several fireplace brands
Cons
- Longer than the GFK-160 and GFK4 kits
The AC Infinity AIRBLAZE S14 is the remote control option, with 200 CFM stated airflow and 10 speed settings. For controls that operate the fireplace itself, see universal fireplace remote controls.
Its DC motor is designed for a fireplace with space underneath its floor or in a compartment.
At 15.07 in long, it is longer than the GFK-160 and GFK4 kits here. The system draws cool air through lower vents, heats it around the fireplace, then pushes it through the upper vent, so the fireplace needs that airflow path and enough room for the fan.
The wireless remote adjusts airflow, and the fan retains its speed setting when power is shut off. AC Infinity lists compatibility with several fireplace brands, including Lennox, Hearth Glo, Majestic and Rotom.
Choose it when your fireplace has the correct underfloor or compartment space and you want remote speed control. Measure carefully because its 15.07 in length may rule it out where shorter kits fit.
Criditpid GFK4 FK4 GFK4A GFK4B Fireplace Blower: Best for GFK4 cross-reference matching
- 130 CFM airflow
- Ball bearing blower
- Magnetic thermostat
- Velcro mounting strips
A GFK4 family replacement kit with a harness, speed control and mounting strips for compatible Heatilator and other listed fireplaces.
Pros
- Includes thermostat and rheostat
- Lists GFK4 family cross references
- Foam pads help isolate vibration
Cons
- Confirm model and mounting space before choosing
Criditpid’s GFK4 family kit lists 130 CFM airflow and cross references GFK4, GFK4A, GFK4B and FK4. It includes a ball bearing blower, magnetic thermostat, rheostat, harness, Velcro strips and instructions.
The size is 12.5 x 3.73 x 3.23 in, matching the compact dimensions of the Hongso GFK4 option. Criditpid names Heatilator, Majestic, Temco, Lennox and other fireplace brands in its compatibility details.
The foam pads attach to the fireplace wall and can help limit vibration against sheet metal. The speed control is manual, while the thermostat handles automatic on and off operation as the fireplace warms and cools.
Pick this kit when your existing blower uses a matching GFK4 reference and you want the included harness and mounting strips. Compare the exact fireplace model before you assume a family number fits every unit.
Criditpid FK24 Fireplace Blower Kit for Majestic: Best for FK24 replacements with mounting studs
- 130 CFM airflow
- Sealed ball bearing motor
- Magnetic thermostat
- Pre-wired harness and cord
An FK24 replacement with a bracket and controls for compatible Majestic, Martin, Temco and Vermont Castings fireplaces that have the needed mounting studs.
Pros
- Pre-wired harness and power cord
- Includes noise reduction padding
- Lists FK24 and 54103 cross references
Cons
- Requires two threaded mounting studs
The Criditpid FK24 is the choice for compatible Majestic and related fireplaces with two threaded mounting studs. For another model-specific gas fireplace repair part, see replacement gas fireplace thermocouples.
It includes a sealed ball bearing blower, galvanized bracket, speed control, magnetic thermostat, padding and installation instructions.
Its stated airflow is 130 CFM, and its dimensions are 12.5 x 3.23 x 3.73 in. The cross references include FK24, 54103 and Rotom HB-RB65.
Criditpid says the bracket mounts to the rear of the fireplace on two threaded studs. Check for those studs and verify the model number before choosing it, since this mounting requirement is specific.
This kit makes sense when you have an FK24 replacement need and the mounting points match. If the existing blower uses a different family number, compare that number first instead of choosing by brand alone.
How do you match a gas fireplace fan blower to your unit?
Match a gas fireplace fan blower by the fireplace model, replacement part number, dimensions and mounting style. Cross-reference numbers narrow the choice, but the model label and physical fit still need to agree.
For pellet appliances, compare pellet stove blowers. For temperature control, see wireless pellet stove thermostats.
Look for the model plate in the fireplace manual or on the unit itself. Record the full model number, then compare it with the kit’s named compatibility list and any cross-reference number on the original blower.
Next, measure the available space and note how the old assembly attaches. Some kits use wall pads or strips, while the FK24 option here requires two threaded studs; a kit that is too long or tall cannot be made compatible by its airflow rating.
Finally, compare the power connection, thermostat and speed control with the fireplace instructions. If you are unsure how those connections work, use a qualified fireplace technician rather than guessing.
What matters more: airflow, fit or controls?
Fit comes first, because a blower that cannot mount in the fireplace cannot circulate heat. After confirming compatibility and clearance, choose the airflow and controls that suit your room and habits.
The traditional kits here range from 118 to 180 CFM, while the AC Infinity option states 200 CFM. These figures can help compare products, but they do not prove how much warmth a particular room will gain; fireplace design and vent paths also matter.
A magnetic thermostat can automate on and off operation as the fireplace heats. A rheostat gives manual speed adjustment, while the AIRBLAZE S14 uses a wireless remote with 10 speed settings.
For a direct replacement, the correct part number and mounting setup matter more than a higher airflow figure. If your fireplace uses a specific Heatilator family, compare our guide to the best Heatilator fireplace blower kit and our best FBK-250 fireplace blower kit guide.
When should you replace the motor instead of the full kit?
Replace only the motor if the blower housing, wiring and controls are still suitable and you can match the motor replacement precisely. A full kit makes more sense when you need the fan assembly, thermostat or speed control too.
Before buying a motor, compare the existing part number, shaft or mounting details, wiring and electrical requirements. Our guide to best fireplace blower motor replacement focuses on motor-only options.
Wood stove systems also use blower parts and insert fans, but their fit depends on the stove and fan design. See our guides to the best Englander wood stove blower, best wood stove blower motor and best VODA heat powered stove fan for those separate setups.
A replacement motor should match the original assembly’s electrical and mechanical requirements. For a three-wire unit, use our guide to 3 wire fireplace motor replacement before selecting parts.

Which fireplace blower kit should you choose?
Choose the Hongso GFK-160 if your fireplace matches its references and you want a pre-wired 160 CFM dual blower. Pick the Adviace or Criditpid GFK-160A when their listed models and measurements better match your unit.
For a GFK4 family replacement, compare Hiorucet, Hongso and Criditpid by model reference, dimensions and included controls. Choose the FK24 only when the cross-reference and threaded mounting studs match, and consider the AIRBLAZE S14 when its longer size and remote control suit the fireplace compartment.
A compatible fireplace blower kit starts with the correct model and mounting fit. For an older unit that may need a larger change, see Best Gas Fireplace Insert For Old Fireplaces and measure the existing opening before comparing insert options.

Frequently asked questions
How do I choose the right fireplace blower kit?
Match the kit's cross-reference number to your fireplace manual or existing blower, then check the dimensions and mounting method. Also compare the controls and cord with your available setup.
A shared brand name alone does not confirm a fit.
Can a fireplace blower kit fit any gas fireplace?
No. Fireplace blower kits are made for particular models, mounting spaces and electrical arrangements.
Some kits list several compatible models, while others need specific studs or a particular compartment.
Check your fireplace model number and the original blower's part number before buying.
What do the thermostat and rheostat do?
A thermostat can switch a blower on as the fireplace warms and off as it cools. A rheostat lets you adjust fan speed manually.
Some retrofit kits include both, but control details vary, so check that the kit matches how you want to run the fan.
Should I replace the motor or the full blower kit?
Replace only the motor when the existing blower assembly and controls are in good shape and you can match the motor's part number and wiring. Choose a full kit if you need a blower, thermostat, speed control or harness together.
For motor options, see our best fireplace blower motor replacement guide.
Can I install a fireplace blower kit myself?
Some kits include a pre-wired harness and installation instructions, but the fit and wiring depend on the fireplace. Follow the fireplace and kit instructions, and disconnect power before service.
Use a qualified technician if you cannot identify the correct model or wiring.
