It must then be connected to a safe chimney system to carry the products of combustion outside the house.
A common mistake is to assume that stove pipe should be installed with the male-end up because this is the way the smoke goes. However, if you fit it this way, you'll later find a black liquid - creosote - oozing down the pipe. Installing with male-end-down allows the creosote drippings to go back down into your stove instead of running down your pipe onto the stove or floor.
Single-wall stove pipe is used for most applications but only if the clearance to combustibles is at least 18" along the length of the pipe until it enters the chimney. Double-wall stove pipe is used where the clearance is less than 18" at any point along its length. Typically, double-wall stove pipe allows for 6" clearance from wall combustibles and 8" from ceiling combustibles. It's ideal when installing a newer close-clearance wood stove or appliance.

We also stock double wall black connector pipe which is far superior to single wall pipe and requires only 6" clearance to combustibles. This pipe is sometimes referred to as close clearance pipe
