I'm starting this thread to document some Tips and Tricks for operating and maintaining the Enviro M55 pellet stove. I've owned my M55 for about 8 years now and is used as our primary heat source.

Anyone can contribute to this conversation and I'll edit this first post with links if appropriate. If I get enough links I may organize them by topic. But for now, it's just a list.

Here we go:

-An excellent thread on long term ownership and maintenance by member Threerun is here:
https://www.hearth.com/talk/threads/new-enviro-m55-fs-stove-owner.61814/

-Replacing the tactile push buttons on the daughter board instead of replacing the entire board by member dana.r. It does require soldering/desoldering skills. My own contribution to this thread starts at post #12 with photos.

-Replace noisy bearing on convection (room air) blower by me (post #2 below in this thread):

-I was having repeated start-up failure with a flashing #3 light. This indicates the exhaust temperature switch isn't sensing high enough heat so the stove shuts down. This is legitimate when you run out of pellets but not on startup. I removed the exhaust temperature switch and cleaned it up so the heat transfer to the switch is better. This solved the problem with failed starts.

-Not hard to find with a Google search, but here is a link to all the manuals that Enviro publishes:

I replaced the outer bearing on my convection (room air) blower when it started making a lot of noise. I didn't document with photos, but it's wasn't a difficult job if you have some mechanical skills.

The bearing I used is an NTN Bearing 608ZZ Single Row Micro Ball Bearing, Normal Clearance, Steel Cage, 8 mm Bore ID, 22 mm OD, 7 mm Width, Double Shielded found here :
