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.

Thanks Don. How high of a potential damage factor is there using the drill wire brush routine? Would be a little concerned on potential damage to impeller blades...

If they get damaged, then that maybe a good indication to replace the blades and/or the blower. I always carry a set of all different blades with me and of course a blower.

Hello
Yes , there are venders for everything .
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.

Geez, let me be more specific. Who is your vendor for impeller blades? Other than OEM.

This is a public forum, not for personal Business or trade secrets. Geez! If u need some they are on my site.

Your welcome Boo Boo, I am trying to show all the issues i have found with exhaust blowers here and yet there is one more! The impellers on the blower in the pic below were so rusted and brittle, one broke off. See pic!
Yes after 3 seasons you should check for all of these problems!

My impellers are still very clean and shiny However I have not pulled it to oil it or the shaft. also the distribution blower

I recommend using a 2 inch long needle bottle with light weight machine oil. It is long and thin to get all the way in! Gets oil on the shaft where it needs to go!

Such as with this quote. Really you have access tons set of evey style blade and blower on your truck? That's a big truck dude. Harman used 5 different blades, Quad has 4, Enviro has 3 but you'd have to go to the way back machine to find a stove with one of them, USSC has 5 that I know of, Dansons (now HHT) has 3 and so on and so on. There are over 140 models of stoves in operation and you are the God of parts. You actually have them all with you, at the ready? Clearly you have much better access to parts than any other independent tech in the world! There are more than 130 different styles or more and you have all of them? Wow.

I take exception with a lot of what you float around here because I live this life as an independent tech. I have worked really hard to know what I know. To get parts, shoot... Just to get an account sometimes to get the parts is half the battle. You don't have to make yourself more awsomer than you already are. Gosh, pinch yourself, you're a person just like the rest of us.

I usually have all the parts to work on a customers stove. My big secret is that I ask "what kind of stove do you have?" Then I pull them from my warehouse! Simple LOL
P.S. Exaggerating how many different impeller blades that are needed does not help you. LOL
