PRECAUTIONS

DO NOT BEGIN INSTALLATION UNTIL YOU READ THE FOLLOWING PRECAUTIONS.

!

WARNING

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

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.

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.).

INSTALLATION

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 position except
upside down (see figure 1). The arrow on the bottom
plate indicates the 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 figure 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.

7. See wiring pages 3-6 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.

INSTALLATION

PILOT GAS CONNECTION

Install fitting into pilot gas outlet (see figure 3), 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 1½
turns.

SYSTEM WIRING

REFER TO AND FOLLOW THE APPLIANCE MANUFACT­URER'S WIRING DIAGRAM. USE THE TABLE ON PAGE 1
TO IDENTIFY THE PROPER TERMINAL IDENTIFICATION
FIGURE FOR THE GAS VALVE.
