INTRODUCTION

→This 4–way multipoise Category I fan-assisted furnace is CSA (A.G.A. and C.G.A.) design-certified for natural and propane gas and for installation in alcoves, attics, basements, closets, utility rooms, crawlspaces, and garages. A 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. A CSA (A.G.A. and C.G.A.) listed gas conversion kit is required to convert furnace for use with propane 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 db or intermittent operation down to 55°F db such as when used with a night setback thermostat. Return-air temperature must not exceed 85°F db. Failure to follow these return-air 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 oper- ating the furnace.
