Short answer: A gas fireplace blower (fan kit) pushes air that has been warmed around the firebox out into the room, so heat spreads farther instead of staying near the fireplace and rising to the ceiling. You'll get the most from one if you plan to use the fireplace for heat in a medium or large room or an open floor plan. If your fireplace is mostly for ambiance, sits in a small room, or you want the quietest possible setup, you can skip it. Either way, decide before the wall is finished: on most Kingsman fireplaces the fan is an optional kit that needs a 120V receptacle, and some models want it installed before facing goes on.
What a gas fireplace blower actually does
A direct vent gas fireplace heats a room two ways. Heat radiates through the glass front, which you feel when you sit nearby. The fireplace also warms air in the space around the firebox. Without a fan, that warm air drifts out slowly on its own. With a fan, it's pushed out into the room.
Kingsman's own manuals describe the tradeoff plainly: turning the fan down with the variable speed control lowers its noise, and it also "will reduce the volume of heated air circulated into the room by the fan." That's the whole job of the blower. It doesn't make the burner produce more heat. It moves the heat the fireplace already makes to where you're sitting.
Kingsman doesn't publish heat-output figures with and without the fan, so we won't give you a percentage. What we can tell you is what the fan needs, how it behaves, and which models in our catalog include one or offer one.
Do you need one? A quick checklist
A blower is usually worth it if:
- You want the fireplace to take the chill off a living room, great room or basement, not just look good.
- The room is open to a kitchen or dining area and you want warmth to reach beyond the sofa.
- You're choosing a higher-input model, such as a 60-inch linear or a high-capacity unit, and want that heat spread out instead of building up near the ceiling.
- You'd like a remote or thermostat to manage comfort. On Kingsman's Proflame 2 (IPI) models, an optional remote can also control the fan.
You can probably skip it if:
- The fireplace is mainly decorative, or you run it on low for the flame.
- It's in a small room or bedroom where radiant heat through the glass is already plenty.
- Low noise matters more to you than air movement. Kingsman notes it's normal for the fan to make some noise when it comes on.
- You need the fireplace to work during power outages and there's no outlet in the plan. A millivolt fireplace can run without power, but its fan can't.
Which Kingsman fireplaces include a blower, and which offer one
This is the part most buyers miss. Kingsman fireplace inserts include a blower as standard. Kingsman zero-clearance fireplaces list the fan kit as an optional feature, so you add it when you order or before the wall is finished.
| Kingsman model (sold at Lumiflares) | Type | Blower | Fan kit named in the manual |
|---|---|---|---|
| Capella IDV26, IDV24, IDV34, IDV44 | Gas insert | Standard: "heat activated blower with variable speed control" | Built in |
| Solara II ZCV3622, Skyline ZCVRB3622 | Zero clearance | Optional | Z36FK |
| Linear 47 ZCVRB47, Linear 60 ZCVRB60 | Zero clearance, linear | Optional | Z46FK |
| Clean View 42 See-Through MCVST42 | Zero clearance, see-through | Optional | Z46FK |
| Heritage HBZDV3628, HBZDV3624, HBZDV4228, HBZDV4224 | Zero clearance, traditional | Optional | Fan kit (see manual) |
| Clean View 39 ZCV39, Clean View 42 ZCV42 | Zero clearance | Optional | Confirm with us for your model |
Standard and optional status comes from Kingsman's product pages. Fan kit numbers come from each model's current installation manual. We sell the Kingsman Z36FK variable-speed fan kit for the 36-inch Solara II. For other models, contact us with your model number and we'll confirm the right kit.
What comes in a Kingsman fan kit
The Z36FK kit for the ZCV3622 and ZCVRB3622 includes, per Kingsman's manual:
- A fan with a 4 ft cord and two 14-inch leads
- A wall-mount variable speed control
- A thermodisc (a heat sensor) and its mounting assembly, which fits under the burner pan
The Heritage fan kit lists the same parts: fan, wall-mount variable speed control, thermodisc and thermodisc mount. The thermodisc is why these fans are described as "heat activated." The fan waits until the fireplace is warm before it starts, so it doesn't blow cool air at you. Kingsman's Heritage manual says the fan comes on once the thermodisc reaches operating temperature, about 10 to 15 minutes after lighting. On Proflame 2 inserts such as the IDV24, the manual lists a 5-minute startup delay and a 12-minute shutdown delay, and fan speed is set from the remote.
Power: the detail to plan before framing
A blower runs on household current, even on a fireplace whose gas valve doesn't need it. Kingsman's Heritage manual states that "all optional fan kits are equipped with a 120V, 60Hz, .4amp blower." Kingsman's manuals also say the fireplace's three-prong plug goes into a properly grounded receptacle, and a qualified electrician must wire built-in installations.
Things to settle with your installer and electrician:
- Receptacle location. The fan plugs into a receptacle at the fireplace. If you want the speed control on the wall outside the fireplace, Kingsman's manuals describe a split receptacle so the unit still has constant power for other parts. That matters on IPI models or units with accent lights.
- Millivolt fireplaces. Millivolt valves run without household power, but the fan still needs it. Kingsman warns not to connect 120V to the millivolt valve, switches or thermostat. For millivolt ZCV3622 and ZCVRB3622 units, the manual says the P2 Box fan control module must be used. We carry it as the Kingsman P2BOX.
- Ignition type. If you haven't chosen yet, our guide to millivolt vs IPI vs Proflame 2 ignition explains how each one handles power, remotes and fan control.
Can you add a blower later?
Sometimes, but it's harder than ordering it up front:
- Linear 47 and 60: Kingsman says the fan kit "should be installed before facing material is applied or surround is installed." Once facing is on, the lower face panel can't come off. Treat the fan as a decision you make at rough-in.
- Solara II and Skyline 36: the fan installs through the bottom of the fireplace. If the lower access panel is already covered by non-combustible facing, the burner pan has to come out first.
- See-Through 42: if the fireplace is already installed, the burner pan must be removed to install the fan.
- Inserts: the blower is already included, so there's nothing to add. You still need a grounded outlet the cord can reach.
In every case, the fan kit should be installed by the qualified technician who installs or services your fireplace, following that model's manual.
What does a blower cost to run?
Very little. Kingsman doesn't publish fan wattage, so this example uses the Heritage manual's 120V, 0.4-amp blower rating and assumes the fan runs at full speed the whole time:
- Power: 120 V × 0.4 A = 48 W at most
- Use: 4 hours a night × 30 nights = 120 hours
- Energy: 48 W × 120 h ÷ 1,000 = 5.76 kWh
- Rate: 18.21¢ per kWh, the U.S. average residential price for 2026 in the EIA's October 2026 Short-Term Energy Outlook
- Cost: 5.76 kWh × $0.1821 = about $1.05 a month, or under a penny an hour (48 W ÷ 1,000 × $0.1821 = $0.0087)
Running the fan below full speed uses less. Your own electricity rate may be higher or lower. The gas is the real operating cost, and our guide to what it costs to run a gas fireplace walks through natural gas and propane.
Noise and comfort tips
- Kingsman notes it's normal for the fan to make some noise when it starts. Lowering the speed reduces the sound and the airflow along with it.
- On Heritage models, an adjustment screw on the side of the speed control sets the minimum fan speed, and lowering it reduces the sound level.
- If the fireplace is in a bedroom or a quiet den, consider running the fan only when you want faster warm-up.
- A blower helps distribute heat, but it doesn't change sizing. Pick the right input first with our gas fireplace sizing guide.
Next step
If you're choosing a new fireplace, decide on the fan when you pick the model. Browse Kingsman gas fireplaces or gas fireplace inserts, which include a blower as standard. Adding a fan to a Solara II? See the Z36FK fan kit and other fireplace accessories. Not sure which kit fits, or whether your unit can take one? Use our gas fireplace fit check, or contact Lumiflares with your model number and ignition type and we'll confirm before you order.
