WARNING
!
DO NOT BEGIN INSTALLATION UNTIL YOU READ
THE FOLLOWING PRECAUTIONS.
Properly install gas piping to control.
• Do not remove protective inlet or outlet caps until
ready to connect supply pipe to gas valve.
• Use new supply pipe, properly threaded, reamed,
de-burred, and cleaned.
• Use backup wrench, applied only to provided wrench
flats on inlet boss,when tightening the supply pipe.
Do not grip bracket, solenoid or any other part of
control.
• Do not over-tighten pipe to control (50ft-lbs max.)
• Always install sediment trap in the gas supply line
to prevent contamination of gas valve.
Failuretoinstall properlycan cause gasleakage result-
ing in injury due to fire or explosion.
WARNING
!
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 per-
sonal 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. Clean gas piping of contaminants, cutting fluid, or
other chemicals which might react harmfully with
the gas valve components before install.
CAUTION
!

INSTALLATION
MAIN PIPING CONNECTIONS
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 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. This valve may be installed upright, + or – 90˚ from upright,
or vertical (refer to figure 1). The arrows on the valve iden-
tification label and on the bottom plate indicate direction of
gas flow through the valve
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) or teflon tape that is
approved for all gases, only to the male threads of the
pipe joints. DO NOT apply compound or teflon tape to the
first two threads (see fig. 3 for typical piping connections).
6. Do not tighten piping excessively, as this may damage the
valve (50ft lbs max).
7. See SYSTEMWIRING when making electrical connections.
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.
PILOT GAS CONNECTION
MODELS 36H3X AND 36H6X REQUIRE A PILOT
CONNECTION.
Loosen the pilot fitting until it is finger-tight.
Insert clean, deburred tubing all the way through the fitting.
While holding the tubing securely, slowly tighten fitting until
you feel a slight “give”. Tighten the fitting an additional 1 1/2
turns.
All piping must comply with local codes, ordinances, and/
or national fuel gas codes.

PRESSURE REGULATOR ADJUSTMENT
These controls are shipped from the factory with the regulator
set as specified on the control label. Consult the appliance rat-
ing plate to ensure burner manifold pressure is as specified. If
another outlet pressure is required, follow these steps.
INSTALLATION
Natural Gas: Two-Stage Models - Low outlet pressure will
be factory-adjusted in the 1 to 3.5” W.C. range and high outlet
pressure will be factory-adjusted in the 2.5 to 5” range. The
valve cannot be adjusted outside this range and the high outlet
pressure setting must always be set at least 1.5” above the low
outlet pressure setting.
Single Stage Models- Outlet pressure will be factory-adjusted
in the 2.5” to 5” range. The valve cannot be adjusted outside
this range.
LP Gas:Two-Stage Models - Low outlet pressure will factory-
adjusted in the 4” to 9.5” W.C. range and high outlet pressure
will be adjusted in the 8 to 12” W.C. range. The valve cannot
be adjusted outside this range and the high outlet pressure
setting must always be set at least 2.5” above the low outlet
pressure setting.
Single Stage Models - Outlet pressure will be factory-adjusted
in the 7 to 12” range. The valve cannot be adjusted outside this
range.

leaks at pressure tap plug. Bubbles forming indicate a leak.
SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
PILOT FLAME ADJUSTMENT
(Models 36H3X and 36H6X only)
If the pilot frame is low and does not engulf the bulb of the
mercury flame sensor, the system will not energize the main
valve. If pilot gas pressure is too high, gas will sputter past the
ignition electrode, and may not ignite. High pilot gas pressure
may also cause the flame to lift off the burner, causing the
flame sensor bulb to sense “low” heat.
To adjust the pilot gas pressure, remove the cover screw (See
fig. 5). To REDUCE pilot pressure, turn the pilot adjust screw
(beneath the cover screw) clockwise (
