Attaching Furnace to Wall

4.Connect nylon cap on 3’ (914mm) plug assembly to nylon plug on the wiring harness.

5.Place 7/8” (22mm) strain relief bushing around the cord of the 3’ (914mm) plug assembly. Insert 7/8” (22mm) strain relief bushing into the 7/8” (22mm) hole in the side panel.

Attention! The 7/8” (22mm) strain relief bushing is located within the same yellow envelope as the Installation Instructions and Owner’s Manual.

Attaching Furnace to Wall

When attaching furnace to the wall remove that portion of baseboard and molding on the wall which is behind the furnace. Attach furnace to wall, at the outer casing top, with (2) toggle bolts provided and to floor, at the outer casing bottom, with (2) #10 x 1 1/2” (38mm) screws provided.

Attention! The screw holes on the outer casing bottom are off-set above the floor approximately 3/8” (9.5mm). Do not over-tighten screws and distort the off-set on the outer casing bottom. Distortion of the outer casing bottom will not allow the lower front panel to be attached to the furnace.

Gas Supply

Check all local codes for requirements, especially for the size and type of gas supply line required. On Natural gas lines less than 15’ (4.5m) long, us (1/2” (13mm) pipe; on longer runs, use 3/4” (19mm) iron pipe or equal. On LP gas lines please consult LP gas supplier.

Installing a New Main Gas Cock

Each appliance should have its own manual gas cock.

Amanual main gas cock should be located in the vicinity of the unit. Where none exists, or where its size or location is not adequate, contact your local authorized installer for installation or relocation.

Compounds used on threaded joints of gas piping shall be resistant to the action of liquefied petroleum gases. The gas lines must be checked for leaks by the installer. This should be done with a soap solution watching for bubbles on all exposed connections, and if unexposed, a pressure test should be made.

Never use an exposed flame to check for leaks. Appliance must be disconnected from piping at inlet of control valve and pipe capped or plugged for pressure test. Never pressure test with appliance con- nected; control valve will sustain damage!

A gas valve and ground joint union should be installed in the gas line upstream of the gas control to aid in servicing. It is required by the Na-

The use of the following gas connectors is recommended:

–ANS Z21.24 Appliance Connectors of Corrugate Metal Tubing and Fittings

–ANS Z21.45Assembled FlexibleAppliance Connectors of Other Than All-Metal Constructions

The above connectors may be used if acceptable by the authority having jurisdiction.

Pressure Testing of the Gas Supply System

1.To check the inlet pressure to the gas valve, a 1/8” (3mm) N.P.T. plugged tapping, accessible for test gauge connection, must be placed immediately upstream of the gas supply connection to the appliance.

2.The appliance and is individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

3.The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

Attention! If one of the above procedures results in pressures in excess of 1/2 psig (14” w.c.) (3.5 kPa) on the appliance gas valve, it will result in a hazardous condition.

Checking Manifold Pressure

Both Propane and Natural gas valves have a built-in pressure regulator in the gas valve. Natural gas models will have a manifold pressure of ap- proximately 4.0” w.c. (.996kPa) at the valve outlet with the inlet pressure to the valve from a minimum of 5.0” w.c. (1.24kPa). Propane gas models will have a manifold pressure approximately 10.0” w.c. (2.49kPa) at the valve outlet with the inlet pressure to the valve from a minimum of 11.0” w.c. (2.739kPa) for the purpose of input adjustment to a maximum of 13.0” w.c. (3.237kPa).

A1/8” (3mm) N.P.T. plugged tapping, accessible for test gauge connection, is located on the outlet side of the gas control.

The built-in regulator comes on at approximately 1/4th pressure and full on in 10 seconds.

High Altitudes

For altitudes/elevations above 2,000 feet (610m), input ratings should be reduced at the rate of 4 percent for each 1,000 feet (305m) above sea level. Canadian High Altitudes for locations having an elevation above mean sea level between 2,000 feet (610m) and 4,500 feet (1370m), the manifold pressure is to be decreased from 4.0” w.c. (.996kPa) to 3.2” (.797kPa) w.c. for Natural Gas and from 10.0” w.c. (2.49kPa) to 8.0” w.c. (1.992kPa) for Propane Gas.
