Barometric Damper

Barometric damper

My boyfriend has a keystoker coal stove and when he purchased it he was told to put a barometric damper on the pipe. I have an Alaska Model 140 coal stove but I was never told about that. Is that something I should have on my pipe?

Is your stove hooked to a chimney or direct vent system? If it is a direct vent sytem is it the Alaska vent ( which has the exauhst blower mounted at the flue exit on the stove), or a powerventer like an SWG which mount in the wall of the house? It you have it hooked into a chimney or a powerventer like a SWG type you need a barometric damper. However if you have the Alaska vent you can't use one because the flue gases are under positive pressure and that type venter the rheostat on the exhaust blower should be set with a manometer so the proper draft setting is achived.

My Alaska Model 140 has a hole on the side where the stove pipe goes. I ran it up and out into a this right.

Welcome Anne, you definitely need a barometric damper. When you install it set the weights per the mfgrs. direction to achieve a .04 draft.

You will need a T and the barometric damper. Installation instructions will let you know where to place it on the pipe. If you can get your hands on a draft gauge that would be the best way to verify everything is working properly after the install. :)
