CAUTION
!
PILOT GAS CONNECTION
Install fitting into pilot gas outlet (see fig. 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 1

turns.
MAIN PIPING CONNECTIONS
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 compound or teflon tape to the first two
threads (see fig. 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. 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

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 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.
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 pro-
tection must be provided to shield the control from
exposure to water (dripping, spraying, rain, etc.).
WARNING
!
If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury or loss of life.
