INTRODUCTION

Series 140/E 4-way multipoise Category I fan-assisted furnace is CSA 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 (16_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.
