Certified for installation in a Residentail Type home in the USA and Canada. Also may be installed into a Manufactured

As a Primary Furnace—the unit functions independently of any other system. The "Room Air" blowers will come on
when the plenum and exhaust temperatures reach a preset point programmed into the furnace's circuit board (PCB). Unit
may also be used as a stand-alone shop heater. This is the only approved installation configuration in which ductwork
or return air is not required. All other configurations utilizing a ductwork system must supply return air to the appliance.
As a Secondary (Add-On) Furnace—the unit aids an existing gas/electric furnace helping cut down on operation time.
It is recommended that only a authorized technician install your Multi-Fuel Furnace, preferably an NFI certified specialist.
Canada requires that the installation of the pellet-fuel furnace shall comply with the applicable requirements of CSA-B365.
