Over Firing Summit

[Doddington]

Wondering if anyone else has it where their stove cruises for a couple hours and then randomly the wood starts to off gas and heat spikes while secondaries burn strong for a while before it settles down again? I have a PE Summit and my stove will sit around 500-600f flue probe temp for 3+hrs then the fire will jump up 750-900f when wood starts off gassing even with the air vent fully shut. Thinking it’s more of a wood thing than a stove thing?

I just recently added a PE blower and blocked the boost air hole to see if that helps at all. Added a key damper last year and had a draft test done but fell well below manufacturer spec and have noticed very little difference with key damper. Going into second season with this stove and still very frustrating I can’t get it to burn properly like so many other manufacturers out there.

Can you describe your install? Height, turns etc. how and where are are you measuring temps. How do you use the damper.

This is a picture of my install. Overall about 22’ of flue with double wall and insulated flue with 2x 30degree bends between the stove and ceiling adapter. I have a condar probe thermometer in the double wall flue 18” above the stove as well as a STT thermometer that I used as a secondary reading. Damper control isn’t really something I have a system down for at this time. Have tried not using it, closing it half way and all the way (still 30% air flow when closed I believe) once flue is at temp.
