Does the damper just compensate (??) for a stove that isn't air tight? Or does it keep heat from going up the chimney?? SWMBO is complaining that the stove doesn't heat as fast as her glass fronted one in the living room.... Keep telling her that it's not the same type of stove and she needs to be patient, but if a damper in the pipe would help.... I'll put one in..... stove itself is tight tho..... Just one that takes a day or so to warm everything up and keep comfortable..... [Reply]   [No Email]

But with either draft control or damper as others have said get it going good then dampen it down some. BUUUUUUT at least once a day let it roar good for a few minutes so that flame will carry up the flue so that if you have accumulated any creosote it will burn it off. That way you will have a friendly chimney fire every day and you won't have bad one that you need to invite the fire department to.   [Reply]  [No Email]

Is my 6" smoke pipe too small? The stove is an old 230 gallon oblong stove fuel tank.   [Reply]  [No Email]

Ideal stack has no bends or horizontal sections. And runs above the condensation point of creosote. Taller is usually better. 6" is on the small side unless the fires are always small, hot and clean burning with the air intake open. It can't be avoided on a natural draft stove . Some combustion heat has to be used to hear the stack to make the stove draw. Instead of the heat warming your building.   [Reply]  [No Email]

The draft however, does. Once you get your fire started, cut the draft on the front of the stove down and the fire will bank down on it's own. If there is less draft, less air comes into the stove, and less goes up the chimney. So more of the heat being given off transfers to the steel and therefore into your heating space. Open the damper, and close down on the draft.....   [Reply]  [No Email]

Important if the stove is not airtight and over fires. Otherwise it's not needed and tends to accumulate creosote. I took mine out on my small vermont castings to get it to run hotter. there are fan driven stove pipe adapters that get more heat out of the stovepipe but be careful of creosote buildup in your chimney.   [Reply]  [No Email]

With the damper wide open or missing, the fire's CO2 goes straight up the flue pipe where as when closed, tends to smother the fire.   [Reply]  [No Email]

Let your stove get up to heat then close down the damper just above where it starts to smoke. This will slow the burning rate and keep more heat in the stove where it warm the house not the outside. They are very easy to install. Walt   [Reply]  [No Email]

Then, the damper should be progressively closed as the stove continues to heat up.. At some point, you will notice the heat output go UP..as the stove goes into "Secondary Combustion".. That is the point where you want the damper closed and the coals will last a long time..and the fire will not roar up the chimney.. My old "Atlanta Stove" has an automatic air inlet damper that regulates the fire well, but I always operate the Stove-Pipe damper to get the best out of the hot stove.. Ron..   [Reply]  [No Email]
