ACategory I fan--assisted furnace is an appliance equipped with anintegral mechanical means to either draw or force products ofcombustion through the combustion chamber and/or heatexchanger. The furnace is factory--shipped for use with naturalgas. This furnace is not approved for installation in mobilehomes, recreational vehicles, or outdoors.6080 / 27 C/ 16 CA06745Fig. 2 -- Return Air TemperatureThis furnace is designed for minimum continuous return--airtemperature of 60_F (15_C) db or intermittent operation down to55_F (13_C)db such as when used with a night setbackthermostat. Return--air temperature must not exceed 80_F (27_C)db. Failure to follow these return--air temperature limits mayaffect reliability of heat exchangers, motors, and controls. (SeeFig. 2.)For accessory installation details, refer to the applicableinstruction literature.NOTE: Remove all shipping brackets and materials beforeoperating the furnace.CODES AND STANDARDSFollow all national and local codes and standards in additionto these instructions.

Precautions willprevent electrostatic discharges from personnel and handtools which are held during the procedure. Theseprecautions will help to avoid exposing the control toelectrostatic discharge by putting the furnace, the control,and the person at the same electrostatic potential.CAUTION!1. Disconnect all power to the furnace. Multiple disconnectsmay be required. DO NOT TOUCH THE CONTROL ORANY WIRE CONNECTED TO THE CONTROL PRIORTO DISCHARGING YOUR BODY’SELECTROSTATIC CHARGE TO GROUND.2. Firmly touch the clean, unpainted, metal surface of the fur-nace chassis which is close to the control. Tools held in aperson’s hand during grounding will be satisfactorily dis-charged.3. After touching the chassis, you may proceed to service thecontrol or connecting wires as long as you do nothing torecharge your body with static electricity (for example;DO NOT move or shuffle your feet, do not touch un-grounded objects, etc.).
