Accentra Low Flame / reduced heat output

Stove Newbie here...

I had a free-standing Accentra installed in mid December 2010 with OAK. I was surprised how much heat that it put out. Pellets are Cubex and Greene Team. Running on stove temp 4, feed rate 4. At that setting under 20* outside temp I can maintain close to 70* on the first floor. I scrape burn pot nightly to break up any carbon build-up.

I clean it weekly and haven't had any issues with small flames/reduced heat output, but has been since the last clean on Sunday. What I did on Sunday, in addition to normal clean, was to pull the vertical panels (on either side of burn pot) and brushed and cleared ash from behind those. There was a fair amount of ash back there, but not too much. I thought that would be a good thing, but ever since this clean I am struggling to get anywhere near 70* on stove temp 5-6 and/or room temp 75*. Any suggestions?

Thanks for the suggestion. I'll clean the ignitor box too. I did that as part of my weekly cleaning, but it won't hurt.

Thanks,

ok, so I went through and cleaned the stove again.

When temps outside are above 25* it seems to produce pretty good heat ~70* when set on stove setting 5 (of 7) with feed rate also 5. When it goes below 25* I cannot seem to keep it above 64* degrees. Same Cubex pellets, scraping burn pot daily twice. (ESP probe was already replaced once a few weeks after initial install.)

I'm stuck on the fact that since I had the OAK installed the fire is smaller and the heat output seems reduced. Dealer says it's cold outside that's why you're getting reduced heat.

Any other suggestions of things to check?



Thanks
