Make the most of your toasty fireplace and cozy living space this winter season by installing or replacing a fireplace blower. These handy contraptions circulate room-temperature air through your fireplace and return the heated air back into your home. This helps keep your home at a comfortable temperature without raising the heating bill. Another perk of fireplace blowers: They keep electronics above your fireplace from overheating. Check out our easy-to-follow instructions below to learn how to install one yourself in a gas-powered fireplace.
What You Need
- WD40 or other lubricant
- Shop vac
- Wire brush
- Fireplace blower kit
Step 1: Remove Plate
With the fireplace completely cool, open the fireplace insert where you will be installing the fireplace blower. Usually this is a knockout plate located at the bottom of the fireplace insert. Remove the screws that hold the insert cover in place. It may be necessary to use a small amount of lubricant to loosen the screws. If this is the case, spray the screws and wait for the material to be absorbed before trying again.
Safety Warning: At the fuse box, disconnect the power to the area where you are installing the blower.
Step 2: Remove Old Blower
If there is an old blower motor installed, you will need to remove it. Place newspapers to the side on the ground to set it on once removed. Unplug the blower from its power source, unscrew the mounting bracket, and remove the motor from the blower space. Disconnect any electrical wiring and place the motor on the newspaper. If your fireplace does not have a motor installed, you will need to prepare it for electrical wiring. Thread the 110/120 VAC service wire from the fireplace junction box through the blower opening, and secure to the blower clamp.
Step 3: Clean Up
If necessary, vacuum the space completely using a shop vac. Use a wire brush to loosen any accumulated or baked dirt, dust, or debris from the corners and back of the space.
Step 4: Choose Blower Motor
If you have removed the blower motor from the space, check the part number of the motor and purchase a replacement motor of the same type. For a new blower, you will need to purchase a blower that has the maximum effectiveness for the size fireplace you have and the room you are heating.
Step 5: Install and Connect Blower
Set the blower all the way at the back of the fireplace and place the speed control knob in the blower space, near the front. Use the support brackets to hold the blower motor in place. Screw in the motor tightly to avoid any unwanted vibration.
Plug the speed control box into the outlet on the back wall. Connect the box and the blower.
Step 5: Turn On and Adjust Blower
Turn the the power back on and turn on the motor to test the electrical connections. Replace the cover plate and screw it back into place.
Use the control module to adjust the blower settings and close cover plate.
