Pellet Stove - Clean or replace your exhaust blower? - Here is how and why. See pics and video :-)

Hello
Been thinking of doing this for a while. How does it look?

How to clean your pellet stove exhaust blower or when to replace it with the upgraded "Low Drafter" blower.

The exhaust blower in a pellet stove pulls air into the burn pot for combustion and then pulls the heated air across the heat exchanger and pushes the air and smoke up and out the flue venting.
This blower must be in top condition for the best combustion to completely burn your pellets and provide the most heat and comfort.

Therefore this exhaust blower should be cleaned and lubricated at least once per year.

If the exhaust blower is faulty, it should be replaced

This video shows what goes wrong with these blowers and the best upgraded replacement.


Here is some suggested ways of cleaning the exhaust blower with simple brushes and lubricants.
Remove the exhaust blower, unclip the 2 or 3 wires and unbolt the 6 nuts or bolts, then pull out the exhaust blower.

1. Brush the impeller blades
2. scrub blades with cylinder wire wheel
3.-4. scrub blades with larger wire wheel
5. - Scrape under impeller blades
6. Brush under Impeller blades
7. Oil motor and motor shaft
8. Spray Dry Moly on impeller blades.

9. Install new white Lytherm High Temperature gasket
10. Bolt in blower and clip wires back together

 

Hello

Here is an exhaust blower with sluggish impeller blades. Even though it works with AC supplied as you can see in the video, I would either have a new blower as a spare or just replace it. The speed may not be consistent at the lower speeds on low heat levels. Replacing it with an upgraded exhaust blower would increase performance.
