2 INTRODUCTION
This multiposition Category IV condensing furnace is
CSA design certified direct vent (2 pipes) or non-direct
vent (1 pipe). The furnace is factory shipped for use
with natural gas. The furnace can be converted in the
field for use with propane gas when a factory supplied
conversion kit is used. Refer to the furnace rating plate
for conversion kit information and part list table
This furnace is designed for minimum continuous return
air temperature of 60 °F (16 °C) or intermittent operation
down to 55 °F (13 °C) such as when used with a
night setback thermostat. Return air temperature must
not exceed 80 °F (27 °C). Failure to follow these
return air temperature limits may affect reliability of heat
exchangers, motors, and controls.
The furnace should be sized to provide at least 100
% of the design heating load requirement.
load estimates can be made using approved methods
available from Air Conditioning Contractors of America
(Manual J); American Society of Heating, Refrigerating,
and Air Conditioning Engineers; or other approved
engineering methods. Excessive over sizing of the
furnace could cause the furnace and/or vent to fail
prematurely.
