    I know having the damper shut too far will produce a lazy and dirty flame, but what risks do you run with the damper too far open? Can this also cause a creosote build up?

    I am waiting on my mag gauge but want to err on the side of caution while I await its arrival.

    too far open tends to produce the cleanest burn, but not the hottest. plus, you risk the 'blow out' factor.

    I find I burn about 30% more pellets at wide open vs 15% closed. after 15% closed, the flame gets lazy on higher settings.

    also extra air must be heated before it goes up the chimney . even if you supplied the exact amount of oxygen for complete combustion ...you already pay the penalty of 79% nitrogen being heated and sent up the chimney
