What do I need to know about connecting a pellet unit to outside air?
Outside air is mandatory for our pellet units to operate properly. These units have been designed and tested with this type connection, because so many homes are airtight and there is not adequate combustion air available from inside the home. The air intake pipe is located at the rear of the burn pot and measures one and one half inches (1
1/2") inside diameter (I.D.). This connection can be made with 1 7/8" I.D. metal pipe and coupler, and should exit through the wall or floor. Be sure to secure the pipe to the unit with a clamp or aluminum tape. The outside end of the pipe should be covered (screened) to prevent foreign matter from entering the system. Our Outside Air Kit (Part Number PU-OAK) can be used. If your unit is located below ground level, you will need to run the pipe up and then outside the dwelling. NOTE: If the total run of the connection exceeds 6', use 3" metal pipe (and coupler) instead.
Important Note: If your run of outside air pipe is more than 6' (six feet), you must increase to 3" diameter pipe.
