Pellet Stove Pipe

Installation Tips For Your Pellet Stove Pipe

Installing a pellet stove pipe is a crucial part of the pellet stove installation. The pipe channels the fire's heat to create what is known as the stake effect. As hot air in the stove rises, cooler air charges into the unit through a pellet stove vent. This supplies the oxygen needed for the fire to burn.

Starting the fire with a good hot burn in the stove will facilitate a vigorous draft to flow. A neutral zone lies between the lower and higher-pressure zones of the house. This zone has a tendency to move towards the space with the largest air leakage. When the outlet, or top of the stove pipe, is situated above the ceiling of the home, the pipe's neutral pressure zone will be above that of the neutral pressure zone of the home. This is the way things ought to ideally be.

Proper pipe placement creates a gradual and easy flow of air into the unit and out of the pipe even when there is no fire burning.

Placement of the Pellet Stove Pipe

If you are building or designing a new home, it’s strongly advised to install the stove pipe inside of the home. If a more traditional outside pipe is used that is constructed along the outside of the home, valuable heat will be lost from the cold air outside.

If the air temperature of the chimney falls below that of the air inside the home, low pressure will occur in the chimney. The will cause the cold air from the chimney to be sucked into the home. This is known as the "stack effect". In this course of events, the home has now become a more effective chimney than the pipe.

So, when a fire a started, smoke will fill the entire room.

Proper Size of the Pellet Stove Pipe

The stove pipe should match the size of the pellet stove. In other words, the flue size needs to match the stove outlet.

If the pipe is larger than the stove outlet, exiting exhaust from the stove will begin to slow, which will increase buildup and decrease efficiency. The best performing chimneys are also insulated.

It is possible to reline older masonry chimneys to safely and efficiently connect to modern stoves. The liner of the stove chimney should be continuous from the stove outlet to the top of the pellet stove pipe.
