INSTALLATION INSTRUCTIONS
Operator: Save these instructions for future use!
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY
AND/OR PROPERTY DAMAGE.
DESCRIPTION
This multi-function gas controls combines into a single
compact package the functions of 3-position gas cock, a
main gas valve and a pressure regulator. The pilot outlet
is plugged, but will accept a 1⁄4” pilot line connection. This
control can be mounted in any orientation except upside
down.
To permit replacement of a variety of valve sizes, this
control is furnished with three reducer bushings (two 3⁄4” to
1
⁄2” and one 1⁄2” to 3⁄8”). Also included is a conversion kit
which allows this valve to be used at regulator settings of
4.2” W.C. to 11.0” W.C.

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, 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.
!
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.
4. DO NOT USE WIRE JUMPER on pilot systems, such as standing pilot, proven pilot, or
spark-to-pilot ignition–a fire and/or explosion may result.
5. 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.
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.).

NOTE:

A Drip Leg In Piping
Figure 1. Typical gas valve piping
NOTE
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.
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 com-
pound 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 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.

INSTALLATION
PRESS
TAP
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 11⁄2 turns.

INSTALLATION (cont’d)
SYSTEM WIRING
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electrical power to system at
main fuse or circuit breaker box until installation
is complete.
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.
The typical wiring diagrams (figs. 3 & 4) show only the
terminal identification and/or wiring hook up. Always refer
to wiring instructions provided by Equipment Manufacturer for system hookup operation.
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. 5). 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.

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. 6).
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.
NOTE
If adjustment to higher range (4.2” W.C. to 11.0” W.C.) is
required, use conversion kit packed with control.

may result causing property damage, personal injury or loss of life.
A. This appliance has a pilot that must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING, smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
FOR YOUR SAFETY
"WHAT TO DO IF YOU SMELL GAS"
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any
phone in your building.
LIGHTING INSTRUCTIONS
1. STOP! Read the precautionary information above.
2. Set the thermostat to lowest setting.
3. Turn off all electrical power to the appliance.
4. Depress gas control knob slightly and turn clockwise to
OFF (see fig. 6). If knob is in ON, turn clockwise to PILOT,
then depress knob slightly and turn clockwise to OFF.
