Pellet stove pipe
A pellet stove pipe is designed to be used in conjunction with Pellet Stoves or Pellet Boiler Stoves and is a single wall pipe which connects to Twin Wall or Flexible Chimney Liner.
Available in 3" (80 mm) and 4" (100 mm) internal diameters, these pipes can be used in conjunction with any narrow diameter stove. Primarily designed for use with pellet burners they require joint seals to prevent any forced flue gases from escaping.
Pellet Stoves need to stand away from a wall by about 8 inches (200 mm) to allow for a small condensation trap which must be fitted on the flue immediately it leaves the stove.
The flue for pellet stoves can be installed into an existing masonry chimney usually using an approved chimney liner to keep the old chimney liner from degrading and possibly falling in and blocking the exhaust gases. If you have a standard brick 9 inch sq flue as in most UK houses built in the last century, it is advisable to line it with a single 5 inch single wall flue liner.
Proper flue size (diameter) is very important for safe and efficient operation. Pellet stoves generally use only a small diameter flue pipe of 80 mm. Be sure to seal the joints and seams of the flue with a sealant recommended by the flue manufacturer or supplier.
Pellet stoves are required to stand on a hearth but because the temperature at the base of the stove never gets too high this need only be a half inch (12.5 mm) high rather than the usual 50 mm.
