Leak Check

After gas piping is completed, carefully check all piping

connections (factory and eld installed) for gas leaks. Use

a leak detecting solution or other preferred means.

NOTE: If emergency shutoff is necessary, shut off the main

manual gas valve and disconnect the main power to the

furnace. The installer should properly label these devices.

Some soaps used for leak detection are corrosive to

certain metals. Carefully rinse piping thoroughly after

leak test has been completed. Do not use matches,

candles, ame or other sources of ignition to check for

gas leaks.

CAUTION

The furnace must be isolated by closing its individual

manual shut-off valve and disconnecting from the gas

supply system the during any pressure testing of the gas

supply system at pressures less than or equal to 1/2 psig

(3.48 kPa, 14 inches w.c.).

When testing pressure of gas lines, gas valve must be

disconnected and isolated. See Figure 26. Gas valves

can be damaged if subjected to pressures greater than

1/2 psig (3.48 kPa, 14 inches w.c.).

IMPORTANT

Electrical

ELECTROSTATIC DISCHARGE (ESD)

Precautions and Procedures

Electrostatic discharge can affect electronic components.

Take precautions during furnace installation and service

to protect the furnace’s electronic controls. Precautions

will help to avoid control exposure to electrostatic

discharge by putting the furnace, the control and the

technician at the same electrostatic potential. Neutralize

electrostatic charge by touching hand and all tools on

an unpainted unit surface, such as the gas valve or

blower deck, before performing any service procedure.

CAUTION

The unit is equipped with a eld make-up box on the left

hand side of the cabinet. The make-up box may be moved

to the right side of the furnace to facilitate installation. If

the make-up box is moved to the right side, clip the wire

ties that bundle the wires together. The excess wire must

be pulled into the blower compartment. Secure the excess

wire to the existing harness to protect it from damage.
