Fire behind the burn pot of a Harman Accentra FS...

TonyVideo said:

Mine is removable but there is no way that pellets could lift it up. It is on a grooved track. There is nothing the pellets could grab a hold to lift unless the plate possibly have carbon build up and it would have to have a lot. The weight of plate is too heavy. The path of least resistance would be out not up for the pellets. The burn pot would have to have a lot of carbon build up to force the pellets up and not out. The plate is at angle down to the entrance. The weight of the plate alone would make it unreasonable. Clean the plate so it is smooth with a wire brush then the pellets would have to slide by.

As I previously stated I did not believe it possible until I saw it with my own eyes ...
Your reasoning was mine before I saw it.. as far as cleaning
The Harman tech commented that he never saw a stove kept so clean... I clean the burn pot minimum of twice daily...
once in the afternoon and once before going to bed... it definitely has no carbon build up causing any problem... much less a lot of build up... most I ever get off is a very thin spot here or there... As far as the flame guide being cleaned ... I clean it at the same time as the burn pot...I have wire brushes to get the ash off and when it has turned to carbon, then I remove it ( the guide) and clean it to a perfectly smooth state...
So in this case there is no way it is because of any type of build up...
We still have the original ignitor and it was working perfectly (7 years of burning between 4-6 tons of pellets a season...the tech could not believe it ... that is how clean we keep the stove... no ash build up there either...
Mine is also on the same track and grooves... Harman only makes 2 different flame guides for all the different models of pellet stoves (from what I have been told ) and they are both grooved and sit on the burn pot...

I wish it was a cleaning problem that would be a very easy thing to fix...

I would like to see pictures after the stove is turned off and cool. Don't do anything other than open the door and take 5 or 6 angles, then we can dissect and discuss before cleaning and taking more pictures.

Will do in a couple of days ... just had it off and cleaned it yesterday so no sense doing it while it is perfectly clean
Can tell you what I saw until I take the pics ...
thin coating of creosote ( shiny black on the bottom of the burn pot { by bottom I mean below the ignitor access door that is removable )
thin layer of fly ash on the metal shelf around the burn pot
and a very thin coating of creosote on the sides of the burn pot... The creosote coating is exactly where the flames burn out side the pot .
So that was no surprise to me
I wire brushed the creosote off as to not have an additional source of possible flames...
other than that it was just normal cleaning brushed off grates then removed and cleaned behind grates empty ash pan which only had less than an inch of ash in it...
vacuumed ignitor hole and the top where the ash builds up ( not sure what they are coils or fins ) but they run along the top underneath of the stove ... and cleaned the window...
Like I said when we shut it down for the tech to come in a few days I will snap pics for you and post ...
Hopefully that may show something

Yes I have the one for the Accentra... actually we have 3 of them ... when the 1 fell in the fire that night I did not trust it to not be warped so when the tech was here we purchased another one... and it was the same as the 2 we had ... He took the serial # off the stove to make sure he ordered the correct parts. Also the part # from my Installation & operating manual confirmed it was the right guide that he gave me... Part # 3-00-08534 and that is what the bag had on it and that was also the # on the other replacement we purchased originally to make sure it was not a problem with the guide being warped or worn. That and the burn pot gasket were the 1st things to be replaced at the start of this problem.

No rush...this is the flame guide with the extra notches.

And for your stove:

The 8th post on page one are three pictures you posted, The last in the series looks like the guide is lifted on the right. Odd.

Thanks for the links I think I was already typing my last answer when you sent yours
I got my book out to make sure as I thought I better double check the part #'s... that is what I was referring to in my last post.
Went back and looked at the picture you referenced and I think it may be an illusion because if you look at the straight line below the compass and look at the guide in reference to that it actually looks like the left side is closer (raised) to the line... but again I think just optical illusion in the pic because of angle, taking it through the window , flames etc...
Looking through the flames now and using the straight line under the compass as a reference guide the flame guide is sitting evenly...
Hopefully when I shut it down & get those pics there will be a clue as to what can be done or what is causing this...
Thanks for all your help Never know when we will hit upon the solution.

Try this thread Not sure if Lousyweather is speaking to the FS or insert regarding the Flame Guard bracket, but he and Delta T are servicing dealers.

Thanks for the info I am in the process of researching the part # ... so far Nothing for Harman parts is matching it ... and my dealer still says no such part... I will be calling dealers out of my area tomorrow if I still come up empty on the internet searches . Thanks for the link, frankie from that thread was the one who had given me the suggestion of putting the gasket rope behind the pot

I found the part # 2-00-247435 It is on the 6th page of this download for anyone interested or who may be in need of it
http://r.search.yahoo.com/_ylt=A0LE...Cast.pdf/RK=0/RS=NiVdUoQbQPS8bWgIJQ7YUi.1nzI-

Now I shall call the dealer and insist it is a Harman part that he can get.

frankie what will this part # 2-00-247435 do that the rope gasket isn't doing ?
The rope gasket is certainly holding the flame guide tightly in place ... It just hasn't fixed the flames outside the burn pot issue ... but the flame guide is not moving at all.

Thats O.K. frankie your help has been immense! Thank you again
The gentleman from Cozy Barn explained in detail what is happening and I am going to follow his suggestion and see if it works.
It certainly makes sense as to what he explained and then how the fire starts. I will update as soon as I can. Once I shut the stove down and make changes ... Then run it and see if it fixes the problem .
He really was the most wonderful person.
I wish we had such a pleasant dealer with such knowledge here. You are lucky to have them nearby.
