NOTE:

Maximum pressure to the gas valve for natural gas is

13.8" W.C. Minimum pressure is 5.0" W.C. Maximum

pressure to the gas valve for propane is 13.8" W.C.

Minimum pressure is 11.0" W.C.

All gas fittings must be checked for leaks using a soapy

solution before lighting the furnace. DO NOT CHECK WITH

AN OPEN FLAME!

▲

CAUTION

Use a backup wrench on the gas valve when installing gas

piping to prevent damage to the gas valve and manifold

assembly.

GAS PIPING

The upflow/ horizontal furnace is shipped standard for left

side installation of gas piping. A knock-out is provided on

the right side for an alternate gas piping arrangement. See

Figure 52.

The installation of piping shall be in accordance with pip-

ing codes and the regulations of the local gas company. Pipe

joint compound must be resistant to the chemical reaction

with liquefied petroleum gases.

Refer to piping Table 15, for delivery sizes. Connect gas

supply to the unit, using a ground joint union and a manual

shut-off valve as shown in Figures 52-53.

National codes require a condensation drip leg to be in-

stalled ahead of the controls as shown in Figures 52-53.

The furnace and its individual shut-off valve must be dis-

connected 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).

The furnace must be isolated from the gas supply piping

by closing its individual manual shut-off 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).

THE DOWNFLOW (VERTICAL) MAY BE INSTALLED LEFT OR RIGHT SIDE GAS PIPING
