FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
The 36J22/24/54/55 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 ow to the main burners, a
pressure regulator and a two-position on/o switch
for regulation and electrical shut-o of the solenoid
valves. The 36J24 and 36J55 are also equipped
with a slow-opening pressure regulator for softer
lighting characteristics. When the second solenoid
on 2-stage valves is energized the valve operates
at the second stage (high) outlet pressure setting.

5. Do not use a gas valve which appears to be
damaged. A damaged valve may cause
personal injury and/or property damage
duetoshock,gassuocation,reand/or
explosion. Contact supplier to replace any
valve that appears to have been damaged.
6. Do not use a gas valve that has been in
direct contact with water. Water entering
gas valve may result in concealed internal
damage to gas valve. Personal injury and/
orpropertydamage,gassuocation,re
and/or explosion may result.
WARNING
!
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.
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.).
3. Cleangaspipingofcontaminants,cuttinguid,orotherchemicalswhichmightreactharm-

INSTALLATION
MAIN PIPING CONNECTIONS
NOTE
Refer to warnings and cautions on page 2 before
attempting installation. All piping must comply
with local codes, ordinances, and/or national
fuel gas codes.
1. Turn o electrical power to the system at the
fuse box or circuit breaker. Also turn o 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 ow.
Gas Flow
Direction
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 rst two threads (see gure
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
connections. After all gas and electrical con-
nections 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.
LP GAS CONVERSION
For LP gas conversion, use the LP conversion kit
supplied with this control. Refer to the instructions packed with LP conversion kit.
All piping must comply with local codes, ordinances,
and/or national fuel gas codes.

ADJUSTMENT
PRESSURE REGULATOR
ADJUSTMENT
These controls are shipped from the factory set
for Natural Gas with the regulator set as specied
on the control label. Consult the appliance rating
plate to ensure burner manifold pressure is as
specied. If another outlet pressure is required,
follow these steps. For LP gas conversion, use LP
conversion kit.
NOTE
NATURAL GAS
Single Stage Models – Outlet pressure will be
factory-adjusted in the 2.5" to 5" range. The valve
cannot be adjusted outside this range.
Two-Stage Models: Low outlet pressure will be
factory- adjusted in the 1 to 4" W.C. range and
high outlet pressure will also be factory-adjusted
in the 2 to 5" W.C. range.
The valve cannot be adjusted outside this range
and the high outlet pressure setting must always
be set at least 1" above the low outlet pressure
setting.
OUTLET PRESSURE ADJUSTMENT
1. Turn o all electrical power to the system.
2. Back outlet pressure test screw out one turn,
counterclockwise, not more than one turn.
(see g. 8)
3. Attach a hose and manometer to the outlet
pressure boss of the valve.
4. Turn on system power. Set thermostat to call
for heat (low stage for two-stage systems).
Main burner should light. Proceed to step 7 for
single stage systems.
5. (2-stage only) Remove regulator cover screw
from the low outlet pressure regulator adjust
tower (g. 8) and turn screw clockwise
( ) to increase pressure, or counterclockwise ( ) to decrease pressure. Always
adjust regulator according to original equip-
ment manufacturer's specications listed on
the appliance rating plate. Replace regulator
cover screw.
6. (2-stage only) Set thermostat to call for high
stage.
7. Remove regulator cover screw from the single
stage or high outlet pressure regulator adjust
tower (g. 8) and turn screw clockwise
( ) to increase pressure, or counterclockwise ( ) to decrease pressure. Always
adjust regulator according to original equip-
ment manufacturer's specications listed on
the appliance rating plate. Replace regulator
cover screw.
8. Turn o all electrical power to the system.
9. Remove manometer hose and turn outlet
pressure test screw in to seal pressure port
(clockwise, 7 in-lb minimum).
10. Turn on electrical power to the system.
11. Turn on system power and energize valve.
12. Using a leak detection solution or soap suds,
check for leaks at pressure boss screw. Bubbles
forming indicate a leak. SHUT OFF GAS AND
FIX ALL LEAKS IMMEDIATELY.

switch. Never use tools. If the switch will not
move by hand, don’t try to repair it, call a qualied
service technician. Force or attempted repair may
result in a re or explosion.
D. Do not use this appliance if any part has been
under water. Immediately call a qualied service
technician to inspect the appliance and to replace
any part of the control system and any gas control
which has been under water.
5. Remove control access panel.
6. Wait ve (5) minutes to clear out any gas. If you
then smell gas, STOP! Follow “B” in the safety
information above on this page. If you don’t smell
gas, go to the next step.
