GENERAL INFORMATION
DESCRIPTION
This Category I furnace is designed for installation in a resi-
dential or commercial application. A Category I furnace has a
fan assisted combustion system equipped with an integral
mechanical means to draw products of combustion through
the combustion chamber and heat exchanger. It may be
installed in a basement, garage, equipment room, alcove,
attic or any other indoor location where all required clear-
ances to combustibles and other restrictions are met. It is
designed for natural gas fired operation, for use in standard
and Lo Nox applications.
High altitude and propane (LP) changes or conversions
required in order for the appliance to satisfactorily meet the
application must be made by an authorized contractor: in
Canada, a certified conversion station or other qualified
agency, using factory specified and/or approved parts.
The blower in this furnace is programmed to supply a con-
stant volume of airflow to compensate for duct system static.
The furnace must be installed so that all electrical compo-
nents are protected from water.
