regulations codes or ordinances which apply to the
installation of a vented wall furnace.
Check the furnace nameplate, located in the burner
compartment, to make sure your furnace is equipped to
operate on the type of gas available (either natural or L.P.
gas). DO NOT convert the furnace from natural gas to
L.P. gas or from L.P. gas to natural gas without the proper
manufacturer’s gas conversion kit.
Combustion air is drawn in from the room where the
furnace is located and is vented out of the top of the furnace
vertically through vent piping in the stud space to a roof
vent top. Vent material is not supplied with the furnace.
This furnace is equipped with a vent safety shutoff
system designed to protect against improper venting of
combustion products. Operation of this wall furnace when
not connected to a properly installed and maintained
venting system or tampering with the vent safety shutoff
system can result in carbon monoxide (CO) poisoning and
possible death.
The efficiency rating of this furnace is a product thermal
efficiency rating determined under continuous operating
conditions and was determined independent of any
installed system. The furnace will not function unless the
venting system is installed
