Pellet Stove Exhaust Blower Maintenance Friendly Reminder

[Don2222]

Hello
Foil Tape and RTV silicone is not recommend for use in sealing pellet stove exhaust blower. High temp Foil tape is only good for 300 to 400 degrees F and high temp silicone is rated for to 600 degrees F.
Only the white lytherm is rated for 1,000 degrees F and makes a good seal at high temps.

Also electrical tape is not recommended for taping wires because it gets brittle from the heat.
Only insulated quick disconnects are Approved.
Also the small sheet metal screws did not keep the exhaust flange secure. The bottom screw fell out and the whole flange can be moved back and forth breaking the RTV silicone seal letting smoke in the room especially during startup.
See pics
Pic 1 - old noisy blower with foil seal with loose black case that rattles.
Pic 2 - foil on housing
Pic 3 - Low limit also called proof of fire or system snap disc.
Pic 4 - see green corrosion on wire.
Room blower did not turn on and off with temperature like it should!
Pic 5 - new snap disc with connectors
Pic 6 - new open frame exhaust blower with more magnetic plates for more torque and no case that may rattle
Notice new larger self taping stainless steel screws in exhaust flange with clear silicone for the best look.

Since I read this I've been keeping a eye on my combustion blower temp and its hovering around 190-200 degrees

That is good, in my meeting with England Stove Works we discussed that as the stove gets dirty, the exhaust temperature goes up as the efficiency decreases. So that is a great way to keep your eye on the stove and tell when it needs cleaning!

For what it's worth, that combustion blower will make some noise like rattling. Just replaced mine after one year of service. New one is nice and quiet with better airflow that tells be the previous one might have been defective.

Funny you say that I had a issue with my stove running hotter than normal.. I cleaned the combustion blower and wow sharper flame and the overall temp really went down..

Hello

The new upgraded blower keeps the holes in the burn pot clear so the stove works much better on the T-Stat!

Also stopped the smoldering of pellets during the fire box yo-yo effect. See pics
