When I overfire my wood sstove am I burning off creosote?

When I overfire my wood sstove am I burning off creosote?

PostBy: smokeyCityTeacher On: Sun Nov 29, 2009 6:17 pm

I have found statements online that its good to burn a very hot fire once in a while to burn off creosote.
Is this true ? If so my chimney would be perfect since I regularly over fire my wood burner and have stack surface temps of 900 deg.

( yes ... I know this is bad. Just asking if it burns off creosote deposits in the chimney )

Yes it will. I run my FireplaceXtrordinaire at 100% output at least a couple hours each week. "Overfiring" cannot be good. Just burn it to the stoves limit. I know I am evaporating creosote when the glass begins to clear. Once the glass is clear again, I throttleback a bit. I never let the fire smolder. If you have wood in the firebox that hasn't turned to hot embers yet, you have to provide over-fire air until all the volatiles are burned off.
I have never had creosote build up in my chimney. I inspect it twice a year, but it is always clean as the day I installed it.
Hope this helps.

to be safe - don't rely on "overfiring" your stove to handle creosote. as you know, only inspecting your chimney regularly lets you know if you have a creosote problem or not.

Yep - this is my regular practice. I don't run my stove in any other mode than full capcity. I always let it burn to hot embers over night and by morning there is nothing but powder.

Ill bet my chimney will look like yours when I get it inspected.
