All installations and services must be performed by qualified service personnel.

design-certified to be resistant to the action of the LP gases should be used on all threaded joints.

The burner is setup to be piped to the gas supply through the left-hand side of the furnace. For service purposes, it is recommended the gas union be located inside the furnace.

A drip leg must be used on both propane and natural gas installations immediately upstream of the furnace in order to trap oil, condensate, and other impurities which might otherwise lodge in the gas valve, or plug the main burner orifice. A drip leg shall be provided at the outlet of the gas meter when there is excessive condensation between the gas meter and the furnace.

Failure to install drip leg(s) may void the manufacturer’s limited warranty on the furnace.

For natural gas, the maximum supply pressure is 14.0 in. W.G. and the minimum supply pressure, for purposes of input adjustment, is 5.5 in. W.G.

For propane gas, the maximum supply pressure is 14.0 in. W.G. and the minimum supply pressure, for purposes of input adjustment, is 11.0 in. W.G.

I. ELECTRICAL WIRING

: When testing electrical equipment, always follow standard electrical procedures and precautions.

All electrical wiring must be installed in strict accordance with local ordinances and codes. In the absence of local ordinances and codes, all electrical wiring must conform to the requirements of the National Electric Code, ANSI/NFPA 70-1999, or latest edition.

1.Electrical Branch Supply Circuit

Route all electrical wiring to the left side of the furnace. The power supply circuit to the furnace must be installed and grounded in accordance with the provisions of the National Electrical Code, ANSI/NFPA-70-1999, or latest edition, and all local codes having jurisdiction.

2.Connection Of Power Supply Wires

a.Remove the cover from junction box.

b.Insert 115 VAC wires through the strain relief bushing (or conduit connection as applicable) on the left side of the furnace junction box.

c.Connect the “hot” wire to the black wire.

d.Connect the “neutral” wire to the white wire.

e.Connect the “ground” wire to the green wire.
