1. Do not short out terminals on gas valve or
primary control to test. Short or incorrect
wiring cancause equipmentdamage,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.).
MAIN PIPING CONNECTIONS
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. The control may be installed in any orientation except
upside down. The arrow on the valve indicates the
direction of gas flow through the control.
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.
SPECIFICATIONS
INSTALLATION
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. 1 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.
7. If additional clearance for the gas cock knob is required
when installing the new valve in an existing system,
rotate the knob to the position between ON and OFF.
Depress the knob while turning the valve. The knob
will depress only while in this position.
8. See SYSTEM WIRING 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.
DO NOT BEGIN INSTALLATION UNTIL YOU READ
THE FOLLOWING PRECAUTIONS.
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, fire, and/or explosion.
2. Do not use this control on circuits exceeding
specified voltage.Higher voltage will damage
the control and may cause shock or fire
hazard.
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, fire, and/or explosion may
result.

INSTALLATION (cont’d)
PILOT GAS CONNECTION
Install fitting into pilot gas outlet (see fig. 2), turning until
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.
SYSTEM WIRING
To prevent electrical shock and/or equipment
damage, disconnect electrical power to system at
main fuse or circuit breaker box until installation
is complete.
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.
The typical wiring diagram shows only the terminal
identification and wiring hook up. Always refer to wiring
instructions provided by Equipment Manufacturer for
system hookup operation.

INSTALLATION (cont’d)
ENERGY CUT OFF (E.C.O.)
CONNECTION
A five-function valve uses the two E.C.O. terminals that
are connected to the magnetic assembly where the
thermocouple connects to the 36C valve line interrupter.
Connect the leads from the E.C.O.terminals to the E.C.O.
device on the furnace.Test the E.C.O.device for continuity.
If there is no continuity, the power unit will not hold in.
See figure 5.
If the furnace does not have an E.C.O. device, jumper
the E.C.O. terminals on the valve with the jumper loead
provided.
THERMOCOUPLE CONNECTION
(For .750 VDC (Special), 24 VAC and
120 VAC Models)
The thermocouple connection should be clean to ensure
good electrical contact.
Run the thermocouple nut into the power unit tapping as
far as possible by hand.Then use a small wrench to set the
nut with a 1/4 to 1/2 additional turn. Do not overtighten.
PILOT GENERATOR CONNECTION
(For .750 VDC Models)
Be sure the pilot generator is completely engaged into
the pilot burner.
Be sure that the two terminals from the pilot generator are
securely tightened beneath the proper screws on the valve.
Connect the power unit lead to the high limit and the high
limit to the TH-PG terminal.
PILOT GAS ADJUSTMENT
If the pilot flame 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. 7). To REDUCE pilot pressure, turn the pilot
adjust screw (beneath the cover screw) clockwise. To
INCREASE pilot pressure, turn the pilot adjust screw
counterclockwise. Replace and tighten cover screw.
PRESSURE REGULATOR
ADJUSTMENT
The pressure regulator has been factory adjusted
(see control for specific setting). Although additional
adjustments will not normally be necessary, you may
adjust the regulator. Do not force the adjusting screw
beyond the limits that it can easily be adjusted.
1. Energize valve to ignite main burner.
2. Remove "Reg. Adj." cover screw (see fig. 8).
3. To DECREASE outlet pressure, turn the adjusting
screw (beneath the cover screw) counterclockwise.
To INCREASE outlet pressure, turn the adjusting
screw clockwise.
4. Replace the cover screw. Cycle the valve two or three
times to verify regulator setting.
