product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

1.Use only with type of gas approved for this furnace. Refer to the furnace rating plate 2. Install this furnace only in a

2.Install this furnace only in a location and position as specified in the “Location” section of these instructions.

3.Provide adequate combustion and ventilation air to the furnace space as specified in “Air for Combustion and Ventilation” section.

4.Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in the “Venting” section of these instructions.

5.Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections, as specified in the “Gas Piping” section.

6.Always install furnace to operate within the furnace’s intended temperature-rise range with a duct system which has an external static pressure within the allowable range, as specified in the “Start-Up, Adjustments, and Safety Check” section. See furnace rating plate.

7.When a furnace is installed so that supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by duct(s) sealed to the furnace casing and terminating outside the space containing the furnace. See “Air Ducts” section.

8.A gas-fired furnace for installation in a residential garage must be installed as specified in the warning box in the “Location” section.

9.The furnace may be used for construction heat provided that the furnace installation and operation complies with the first CAUTION in the LOCATION section of these instructions.

10.These Multipoise Gas-Fired Furnaces are CSA (formerly A.G.A. and C.G.A.) design-certified for use with natural and propane gases (see furnace rating plate) and for installation in alcoves, attics, basements, closets, utility rooms, crawlspaces, and garages. The furnace is factory-shipped for use with natural gas. A CSA (A.G.A. and C.G.A.) listed accessory gas conversion kit is required to convert furnace for use with propane gas.

11.See Fig. 2 for required clearances to combustible construction.

12.Maintain a 1-in. clearance from combustible materials to supply air ductwork for a distance of 36 inches horizontally from the furnace. See NFPA 90B or local code for further requirements.

13.These furnaces SHALL NOT be installed directly on carpeting, tile, or any other combustible material other than wood flooring. In downflow installations, factory accessory floor base MUST be used when installed on combustible materials and wood flooring. Special base is not required when this furnace is installed on manufacturer’s Coil Assembly Part No. CD5 or CK5, or when Coil Box Part No. KCAKC is used. See Fig. 2 for clearance to combustible construction information.

INTRODUCTION

The Series 120/C 4-way multipoise Category I fan-assisted furnace is CSA (formerly A.A.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.

These furnaces shall not be installed directly on carpeting, tile, or any other combustible material other than wood flooring. For downflow installations, a factory accessory floor base must be used when installed on combustible materials and wood flooring. This special base is not required when this furnace is installed on the manufacturer’s coil assembly, or when the manufacturer’s coil box is used. See Fig. 2 for clearance to combustible material information.

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 80_F 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.
