FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY
AND/OR PROPERTY DAMAGE.

DESCRIPTION

The 36G/J22, 36G/J23, 36G/J24 and 36G/J52 combination
gas valves are designed for direct spark ignition (DSI) and
hot surface ignition (HSI) system applications. These valves
are equipped with redundant and main solenoid valves that
control gas fl ow to the main burners, a pressure regulator
and a two-position on/off switch for regulation and electrical
shut-off of the solenoid valves. The 36G/J23, 36G/J24 and
36G/J52 are also equipped with a slow-opening pressure
regulator for softer lighting characteristics.

Type of Gas: Natural gas
LP gas (use conversion kit)

Pressure Regulator Setting:

Nat. Gas – 2.5 to 5.0" W.C.

LP Gas – 7.0 to 12.0"W.C.
Ambient Temperature: -40° to 175°F
Pressure Rating: 14" W.C. (1/2 PSI) max.
Voltage: 24 VAC
Frequency: 50/60 Hz
Current: .360 amps

PRECAUTIONS

DO NOT BEGIN INSTALLATION UNTIL YOU READ
THE FOLLOWING PRECAUTIONS.

!

WARNING

1. Failure to turn off electric or main gas sup­ply to heating system could cause personal
injury and/or property damage by shock, gas
suffocation, fi re, and/or explosion.

2. Do not use this control on circuits exceeding
specifi ed voltage. Higher voltage will damage the
control and may cause shock or fi re hazard.

!

CAUTION

1. Do not short out terminals on gas valve or
primary control to test. Short or incorrect wir­ing can cause equipment damage, property
damage, and/or personal injury.

If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury or loss of life.

3. NEVER USE FLAME OR ANY KIND OF SPARK
TO CHECK FOR GAS LEAKS–COULD CAUSE
FIRE AND/OR EXPLOSION.

4. Do not use a control set for natural gas with
LP gas, or a control set for LP gas with natural
gas. Personal injury and/or property damage,
gas suffocation, fi re, and/or explosion may
result.

2. This control is not intended for use in locations
where it may come in direct contact with water.
Suitable protection must be provided to shield
the control from exposure to water (dripping,
spraying, rain, etc.).

INSTALLATION

1. Turn off electrical power to the system at the fuse box
or circuit breaker. Also turn off the main gas supply.

2. If replacing an existing valve, disconnect all plumbing
and electrical connections from the old control.

3. The control may be installed in any position. The arrow
on the bottom plate indicates the direction of inlet gas
fl o w .

4. You should use new pipe that is properly chamfered,
reamed, and free of burrs and chips. If you are using
old pipe, be sure it is clean and free of rust, scale,
burrs, chips, and old pipe joint compound.

5. Apply pipe joint compound (pipe dope) that is

approved for all gases, only to the male threads
of the pipe joints. DO NOT apply compound to the

fi rst two threads (see fi g. 2 for typical piping connec­tions).

6. If you are using a vise or open-end wrench to hold
the valve while installing piping, do not tighten exces­sively, as this may damage the valve (Torque: 375 in-lb
maximum). Do not cross-thread during installation as
this may damage the valve.

7. See SYSTEM WIRING when making electrical con-
nections. After all gas and electrical connections are
completed, turn gas on and check for gas leaks with
leak detection solution or soap suds. Bubbles form­ing indicate a leak. SHUT OFF GAS AND FIX ALL

LEAKS IMMEDIATELY.

SYSTEM WIRING

REFER TO AND FOLLOW THE APPLIANCE MANU­FACTURER’S WIRING DIAGRAM. REFER TO FIG. 1
FOR TERMINAL IDENTIFICATION.

NOTE

All wiring should be installed in accordance with local and
national electrical codes and ordinances.

Always check that the electrical power supply used
agrees with the voltage and frequency shown on the gas
control.

ADJUSTMENT

Controls are shipped from the factory with the regulator
set as specifi ed on the control label. Consult the appli­ance rating plate to ensure burner manifold pressure is as
specifi ed. If any other outlet pressure is required, follow
instructions below.

Outlet Pressure Adjustment Range:

Nat Gas 2.5" - 5"

LP Gas 7.0" - 12"

NOTE

Valves cannot be adjusted outside these ranges for the
specifi ed gas type.

specifi cations listed on the appliance rating plate. Replace
regulator cover screw and tighten securely.

Check for Leaks:

Using a leak detection solution or soap suds, check for
leaks at pressure boss screw or pressure tap plug. Bubbles
forming indicate a leak. SHUT OFF GAS AND FIX ALL

LEAKS IMMEDIATELY.

Turn off all electrical power to the system to connect
manometer hoses.

For models with Pressure Tap Bosses, turn the pressure
test screw (3/32" Hex) in the center of the boss not more
than one turn counterclockwise. Attach a 5/16" hose
and manometer over the tapered outlet pressure boss on
the valve (see fi gure 4). If regulator needs to be adjusted,
please see instructions below. After testing pressure or
adjusting the regulator, turn off all electrical power to the
system, remove manometer hoses, turn outlet test screw
(3/32" Hex) clockwise to seal pressure port. Tighten to 7
in-lb minimum. Turn on system power.

For models with 1/8" NPT threaded taps, the outlet
pressure tap plug will need to be removed and a separate
hose fi tting installed. If regulator needs to be adjusted,
please see instructions below. After testing pressure or
adjusting the regulator, turn off all electrical power to the
system, remove manometer hoses, remove hose fi tting
and re-install plug. Tighten to 60 in-lb max. Turn on sys­tem power.

To Adjust Regulator: Energize the valve. Remove regu­lator cover screw. Turn regulator adjust screw clockwise
( ) to increase pressure, or counterclockwise
( ) to decrease pressure (see fi g. 5).
