If you were lucky enough to get an authentic wood stove, you certainly don’t want to see that money going to waste courtesy of an incorrectly installed stove pipe. You can easily tell if your stovepipe was not installed perfectly. Badly installed pipes will result in backpuffing, which is just a fancy way of describing smoke coming from out of the stove.
An incorrectly installed stovepipe is potentially life-threatening. Ensure that the stovepipe is properly insulated. If for some reason you cannot add insulation to the pipe, make certain that your noninsulated stove pipe does not touch or get close to parts of the house made of flammable material like wood.
Smoke problems tend to arise more often when pipe is connected to an existing chimney. It is imperative to ensure that the pipe matches the diameter of the exhaust flue to avoid creating a back-puffing situation.
You can cut down on creosote leaks by overlapping any joints in the stove pipe by at least 2 inches. Safety is also improved by using fireproof sealant at the joints and securing the joints with three sheet metal screws.
The stovepipe needs to remain as short as you can make it, according to author Charlie Wing in his book “The Visual Handbook of Building and Remodeling.” Wing recommends that horizontal runs are less than 75 percent of the vertical chimney height above the connecting section known as the thimble.
The stove and thimble joints need to fit tightly as do all pipe joints. The draft inside the chimney is adversely affected by loose pipe joints.
Walls and Ceilings
Support any stovepipe that will pass through a wall with a vented thimble that is three times larger than the diameter of the of the pipe itself. Rather than install a stovepipe that goes through the ceiling, use a listed all-fuel chimney. Charlie Wing recommends against ever letting the stovepipe itself pass directly through the ceiling.
