An indoor wood pellet stove must have some sort of vent for it to function properly and safely. Below are several venting options.
This is the least expensive option for a venting a pellet stove. A side wall vent is a pipe that is installed horizontally directly to the outside of a wall. This allows smoke and exhaust to exit the building without needing any additional chimney or other exterior access.
Ceiling and Roof Vent
The most common type of vent for a pellet stove goes up directly through the ceiling and roof. A ceiling and roof vent helps provide a natural draft and allows for vent gases to remain warm as they rise.
Another option is to vent a wood pellet stove directly into an existing masonry chimney. Many pellet stove manufacturers provide specific instructions and installation equipment for this kind of venting.
