    I usually run my damper at a quarter closed when burning during the winter. Does anyone close theirs off ?

    I only close mine when I want to tame the fire a little as my stove is on the cheaper side and doesn’t have any adjustments for the air intake. I plan on remedying this soon.

    I'm guessing you are talking about the flue damper?

    Then yeah, I do damper my drolet down once it gets up to temp. I close the damper a bit better than 1/2 way with no ill effects on the burn. Without the damper, the stove runs way too fast. It is vented into a masonry chimney that is around 30' so the draft does get a bit greedy...!!

    (I shut it off to around 3/4 or more and it started to affect the burn)

    I normally don't close mine on my CFM unless it starts to run away, which sometimes happens with a strong NW wind.

    I only use ours if the wind is strong.

    I have a great old fisher baby bear and it has the air control dial on the door, also have a flue damper about 20 inches above the stove. Have a really good draft and often times need to use the flue damper to keep things under control. Also, like that I can slow things down real fast if I close the flue damper all the way.

    Haven't had a damper for many, many moons. Just use the stove draft and all is well.

    True that.

    But the epa stove I have in the basement is connected to way too many feet of chimney.

    My other two epa stoves are in one story buildings which equals much much shorter chimney. There is no need of a damper on those two.

    Don't have a flue damper on our Drolet Blackcomb, just the intake damper. Once up to temp, close it down and let secondaries burn. We only have about 12' of chimney pipe.

    Pipe dampers are usually only needed on real tall stacks (high draft) or on stoves with no controls (yes, they exist)

    Yeah I have one of those stoves that doesn’t have any controls. I didn’t know that when I bought it nor did I really know any better at the time. It can be really aggravating trying to regulate it with just the flue damper.

    Here is a tool that may make your life a little easier...a manometer. I like to the Dwyer Mark II model 25...it is cheap and plenty accurate for chimney draft purposes. Us wood furnace users often have barometric dampers on the flue which need to be accurately set, and then monitored for proper operation. With the furnace being "out of site, out of mind" most of the time, and proper draft being so vital to the furnace operating safely and efficiently, many of us just leave a Dwyer hooked up all the time and just peek at it when reloading the furnace.
    They are simple to install, hang up plumb and level, drill a 1/4" hole in the pipe, install a metal tube, connect the hose of the Dwyer to the tube, done. Now you can adjust the damper to the same draft number every time...regardless of outside temp, etc. (FYI, -0.04 to -0.06" is a pretty typical setting for most stoves)
    You can buy these on ebay for $20 to $40 pretty much anytime. Here is one that I bet can be bought for $25 shipped.

    The Vogelzang doesn't have any door dampers?

    Thanks for the tip. I’ll definitely look into that.

    No sir. Not this particular model anyway. It has air slots right above the door but no way to adjust how much air it takes in.
