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 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 exces-
sively, as this may damage the valve.
7. If additional clearance for the gas cock knob is re-
quired 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.
NOTE
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 in-
jury 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 dam-
age 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 sys-
tems, such as standing pilot, proven pilot, or
spark-to-pilot ignition–a fire and/or explo-
sion 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 explo-
sion may result.
1. Do not short out terminals on gas valve or
primary control to test. Short or incorrect
wiring can cause equipment damage, prop-
erty damage, and/or personal injury.
2. This control is not intended for use in loca-
tions where it may come in direct contact
with water. Suitable protection must be pro-
vided to shield the control from exposure to
water (dripping, spraying, rain, etc.).
WARNING
