I have a Harman Mark II. It has one air vent in the ash door.
In late Spring and early Fall I need to work hard to prevent "poof" of the coal gas when it finally lights off after feeding it. I've read all the posts I could find on how best to prevent this and have gotten pretty good at it.
My concern is when I'm not in town and my wife and kids are tending the fire. I'm looking for a more idiot proof method to prevent the rapid combustion of the coal gasses.
What I am considering is drilling two 1/2" holes in the sides of the stove, just above the fire bricks to allow a continuous flow of fresh air over top of the coals. I'm thinking this would prevent the buildup of the gas and what gas would build up with light off faster and with less force.
I have a 30' masonry chimney and my barometric damper runs at .06. I don't think two half inch holes would be detrimental to pulling the air up from the bottom.
With 1/2" holes, if it doesn't work, I could easily close them with two bolts. (My stove is old, and I have had to make multiple repairs, modifications, and customizations so I'm not worried about the aesthetics of the unit).
Does anyone think this plan is a good or bad idea?
Has anyone ever tried this before?
Do you think it will work?
( know, I should trade this unit in for a SF260 or an EFM520 but I have not yet found a good deal. )
