Enviro M55 Insert - Problem with build up on glass

Everyone with the insert is having the same problem..Air wash system apparently does not cover that area. Do a search and you will find lots onf complaints about it but no resolutions.

I recently purchased an Enviro M55 insert. There is very little in the instruction manual to guide you. I continue to have a film to cover the same glass area in my stove (right side - facing stove). Any ideas or suggestions? The manual does say to clean the glass weekly, but that is not near often enough - I am cleaning daily.

I am running in manual mode with premium pellets.

Apparently it's an Enviro thing. Here's a picture of my M55 insert

RM - I would suggest contacting the manufacturer to see if it’s on their radar. We have an M55, the soot appears on the glass...for us it’s really not a problem. We clean it weekly and enjoy the heat.

I would ask that some of more experienced folks here…I believe soot on the glass is common amongst many manufacturers to a certain degree.

Actually, Of all the stoves I have checked out over the years, The air wash on the Enviros are pretty darned good. Some stoves have the complete glass is covered in a few hours. I run my stove a whole week and I can still see the flame. Yes the top portion is covered, But the flame is still clearly visible in the center of the glass. In about a day with my Breckwell and 3 days with my Quad. You could not see thru any part of the glass.

One thing I found is low feed does cloud the glass faster than medium and High lasts the longest. This because the air being drawn in that covers the glass has more velocity in the higher feeds do to more vacuum in the firebox.

IMHO an airwash is to assist in helping to keep the glass clean to allow viewing the flame. I don't think many, If any have a perfect airwash system. If there is a perfect one out there I haven't seen it. Hard to put this nicely, But I am thinking your all being a bit over board on this. Your burning fuels that create residues that stick to your glass. Different fuel types will effect the glass build up and maybe your culprit just as much as the airwash. If you want clear glass, Burn the cleanest pellet you can find, Or shut the stove off once a day and clean it. It really is what it is and expecting more might be a bit streached. Only thing I think Enviro goofed on was the pattern is odd looking. If they had the pattern a bit more even, There might be less complaints. Expecting the glass to stay completely spotless? Probably not going to happen!

Attached is 3 pic's of my stove after 5 days. I couldn't be happier compare to other stoves I have owned. Notice the clumps of ash stuck on the baffle! These are O'malleys burning which were below average overall. I get much cleaner glass with cleaner burning pellets.

It isn't an issue with the stove at all.

You can not burn wood and not have residue deposited somewhere.

The residue is going to deposit on all surfaces.

What gets deposited where is a function of temperature at each location and how much air flow there is to stop larger particles from landing in the residue.

I'll resize some nice long low burn pictures later tonight and post them.

Mine does the same exact thing, but I can live with it. As j-takeman said, other manufacturers are far worse. The glass on my quad stays clean as long as it's not running!

Let's see how this comes out the lower numbered picture was after 23 bags over 26 days the higher number picture was at the one ton mark the glass was not cleaned, what changed was the firing rate.

I didn't mean to say that Enviro was the only company that had airwash issues, just that it seems Enviros had the right hand curve thing going. I love my M55 C insert.

I've been thinking about this and I think it might be able to be fixed by installing a steel plate on the left hand side where the air goes back around the backplate. This would force the air to move out of the right side of the stove. By adjusting how much of the left side is blocked one could hopefully balance the air flow on both sides and get the airwash to keep the whole glass clean. Also, the flame would not lean left as it tends to do right now. On mine, the glass stays clean on the left side even after 1.5 weeks of burning.

My XXV gets it in the exact same place, in a hockey stick shap around the top of the glass. It stay limited to the L shape and flame remains visible for a long time.

Ash on the upper right side of the glass is typical on the M55.

Providing it is just grey/tan deposits, nothing at all to worry about. As noted above, deposits are normal. You will have more deposits if you burn more often. You may also notice differences depending on pellet qualiy and heat level settings. Some stoves accumulate deposits across the top of the glass evenly. Some build up in the central portion of the glass. On the M55, it just happens to build up on the upper right side. Has something to do with air currents within the stove. Not a defect. Not a problem.

TIP: Take a moist cloth, dip it in ash from within the firebox, then scrub the door. Takes like a minute to do. The ash acts as a mild abrasive and works very well.
If you have black soot or creosote on your door, this is an indication that routine cleaning or servicing is required. All of this is clearly noted in the manual.
