INTRODUCTION

Fig. 2 – Clearances to Combustibles
This 4-way multipoise Category I fan-assisted furnace is CSA (formerly
A.G.A. and C.G.A.) design-certified. A Category I fan-assisted furnace is
an appliance equipped with an integral mechanical means to either draw
or force products of combustion through the combustion chamber and/or
heat exchanger. The furnace is factory-shipped for use with natural gas.
This furnace is not approved for installation in mobile homes,
recreational vehicles, or outdoors.
This furnace is designed for minimum continuous return-air temperature
of 60°F (15°C) db or intermittent operation down to 55°F (13°C)db such
as when used with a night setback thermostat. Return-air temperature
must not exceed 80°F (27°C) db. Failure to follow these return-air
temperature limits may affect reliability of heat exchangers, motors, and
controls. (See Fig. 3).
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before operating the
furnace.
