6. Venting System
6.1 Exhaust Vent Pipe Requirements
Your KOZI pellet heater works under negative pressure (vacuum). The exhaust fan of
your stove pulls air from the air intake, through the stove and pushes it out the venting.
As this air passes through the burn pot it is used to burn the pellets. Proper vent pipe
sizing is very important to the proper operation of your stove. A proper size ULC/UL
listed type PL or L venting should be used to provide the least resistance for movement of
the combustion air.
