The importance of cleaning your pellet stove exhaust/combustion fan regularly cannot be emphasized enough. As a general rule of thumb you should clean your exhaust motor and exhaust venting after 3 tons of pellet fuel have been burned. If you have lengthy horizontal or vertical pipe runs it should be cleaned more frequently. Additionally if you are burning standard grade pellets, hardwood pellets or other biomass fuels such as corn or sunflower seeds it should be checked and cleaned more frequently. Ash blockage and build-up in the exhaust fan and venting system is the #1 cause for service issues, dirty glass, frequent burn pot cleaning and low efficiency levels.
The pictures below are from the Lennox Profile 20 that we have heating our online department work area. These pictures show the importance of cleaning your venting & exhaust motor regularly. We cleaned the venting completely about 3 weeks ago, but we were having some problems with the exhaust/combustion blower not providing enough draft. As you can see in the picture of the exhaust fan, it has extensive build-up from not operating correctly/running at the correct RPM’s. This directly affected the accumulation and build-up of deposits and residue in the venting. The pics of the vent are after just 2 weeks of burn time with premium grade pellet fuel. If the exhaust/combustion motor is not operating properly, build-up will accumulate rapidly in the fan housing and vent.
If you are noticing a lazy flame, heavy burn pot build-up and black soot on your stove’s glass, the first items you should inspect are the exhaust motor and exhaust vent pipe. The second items that should be inspected are the door, glass and ash pan gasket seals.
Simply running a brush through your venting system is not enough. The exhaust/combustion fan needs to be removed from the housing to be inspected and cleaned as well. When you remove the exhaust motor you MUST replace the gasket seal prior to reinstalling the motor back on the stove.
Once you run a brush through the venting system, we highly recommend you use a leaf blower/vac to suck out the loose ash. This device is powerful enough to pull the ash out of your vent, exhaust housing and most of the ash that accumulates behind the back firewall and upper heat exchange area in your stove.
If your exhaust/combustion motor needs to be replaced we offer factory OEM replacements for most lines of stoves and we also offer a universal exhaust/combustion fan kit that fits 95% of all pellet stove models on the market. Our aftermarket fan is needle point ball bearing motor for superior quietness and longevity; built in the USA. We also recommend replacing the combustion fan paddle blade.
