MODEL F80A

SETTING THE MANIFOLD (Outlet) GAS PRESSURE (F92-1003 36G Valve Pressure Check Kit)

1.Shut off the gas upstream of valve and move valve switch to “OFF”.

2.Using the 3/32 inch hex wrench that is included in the valve pressure check kit, rotate outlet pressure tap screw one revolution counter-clockwise.

3.Attach the 5/16 inch hose that is included in the valve pressure check kit to the outlet pressure boss of the valve. Hose should overlap boss 3/8 inch.

4.Connect 5/16 inch side of connector that is included in the valve pressure check kit to the hose on outlet boss. Connect 1/4 inch side of connector to manometer hose.

5.Turn on gas supply to valve and move valve switch to the “ON” position.

6.Turn on furnace following manufacturer’s instructions.

7.Using a leak detection solution check for leaks at hose connections.

DANGER

SHUT OFF GAS AND FIX LEAKS IMMEDIATELY BEFORE PROCEEDING.

DANGER

A TRAINED, QUALIFIED TECHNICIAN MUST DO ALL REGULATOR ADJUSTMENTS. IMPROPER MODIFICATIONS OR ADJUSTMENTS CAN RESULT IN FIRE OR EXPLOSION CAUSING PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR LOSS OF LIFE.

In some circumstances, high inlet pressure can be remedied with the use of an inline appliance regulator. If an inline appliance regulator is used, ensure that it has the capacity to adequately handle the gas volume required by the furnace and any other appliances receiving gas from the header serving the furnace.

	before proceeding.

If problems were encountered with obtaining enough pressure on the manifold, first examine the gas piping system to ensure that it is correctly sized. Pipe sizing is specified in ANSI Z223.1 / NFPA 54 in the U.S., or the B148 Natural Gas and Propane Installation Code in Canada.

CHECKING THE SUPPLY (Inlet) GAS PRESSURE (F92-1003 Valve Pressure Check Kit)

Check inlet pressure following steps 1 through 15 above using the inlet/supply pressure tap boss.

ELECTRICAL SPECIFICATIONS

Before proceeding with the electrical connections, ensure that the available electrical supply is compatible with the voltage, frequency, and phase listed on the appliance rating plate.

All furnaces are rated 120 VAC, 60 Hz, 1 phase. The amperage rating is indicated on the furnace rating plate.

Each furnace requires a dedicated overcurrent device either a circuit breaker or a Type D, time delay fuse. It is permissible to connect furnace accessories such as humidifier transformers, condensate pumps and electronic air cleaners. If adding accessory equipment to the furnace circuit, ensure that the combined amperages listed on the appliance rating plates do not exceed the rating of the over current device.

DANGER

SHUT OFF ELECTRICAL POWER AT THE FUSE BOX OR SERVICE PANEL BEFORE MAKING ANY ELECTRICAL CONNECTIONS. FAILURE TO DO SO CAN CAUSE ELECTRICAL SHOCK RESULTING IN PERSONAL INJURY OR LOSS OF LIFE.
