PRECAUTIONS
DO NOT BEGIN INSTALLATION UNTIL YOU READ
THE FOLLOWING PRECAUTIONS.
!
WARNING
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.
If you do not follow these instructions exactly, a fire or explosion may
!
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.
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.).
INSTALLATION
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 valve may be installed in any position except
upside down. 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
