NOTICE:
These are guidelines for successful venting of your pellet appliance. The more vertical rise you can obtain in
your system, the better it will perform. Horizontal vent runs can accumulate ash and will need to be cleaned
more often. Try to keep them as short as possible.
We strongly recommend a minimum of 60 inches
(1.5m) vertical, however above the eave is preferred.
Both installations are approved for mobile home
installations. Must use 3 or 4 inch (76 to 102mm) “L” or
“PL” Listed pellet venting or Listed double wall pipe and
authorized Outside Air Kit in mobile homes. Single wall
pipe is approved for residential installations only.
Air Clearance to Pipe:
This appliance was tested with standard 3 inch (76mm)
Listed pellet vent.
Pellet pipe manufacturers Listed reduced clearance pipe
may be use for reduce clearance from 3 inch (76mm) air
clearance to no less than 1 inch (25mm) air clearance to
combustibles for approved Listed pellet pipe.
