A fireplace blower fan accumulates dust much like a portable fan. This accumulation, in turn, reduces the efficiency of the blower. By regularly cleaning your convection fan, you can maintain effective heat distribution.
Here is a list of tools you will need:
- Your stove’s owner’s manual
- A small, soft bristle paintbrush
- A broom or, preferably, a shop vac with a brush attachment
- Tools (e.g., screwdrivers and pliers)
- Synthetic bearing oil (if applicable)
NOTE: Check your owner’s manual for specific instructions regarding the removal and cleaning of your unit’s convection blower.
Here are some basic steps for cleaning a convection blower:
1. Make sure that your unit is unplugged (if applicable), pilot and gas are turned off (if applicable), and the unit has completely cooled down.
2. Locate your unit’s blower. Consult your owner’s manual for the specific location. Generally, the blower can be found in the following locations:
Wood Stove – Below the loading door of an insert OR behind a free-standing unit
Pellet Stove – In the lower rear of the stove; can be accessed through one of the side panels
Gas Fireplaces – Behind the lower access panel of an insert OR behind a free-standing unit
3. Once you’ve located and removed your blower, you’ll need to clean each fan blade fin using your soft-bristle paintbrush.
4. Clean around the blower and motor, if accessible, and remove as much dust and debris as you can. DO NOT use ANY water or liquids to clean the blower as they could damage electrical components.
5. Use a vacuum to remove any loose buildup within the chassis. If you have access to a leaf blower or air compressor, this can be used to blow out any loose buildup.
6. Lubricate any oil ports with two or three drops of synthetic bearing oil. Most convection blowers do not require oiling, so check your owner’s manual or the blower’s tag if you are unsure. OR view our how-to article HERE for more info.
7. Test the blower to ensure that it works correctly.
8. When you are finished cleaning the blower, reinstall it in your unit in the reverse order of removal.
It is recommended that you clean your convection blower at least twice a year for optimum performance.
