INSTALLATION

MAIN PIPING CONNECTIONS
Refer to warnings and cautions on page 3 before
attempting installation. 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. This valve may be installed upright, + or – 90˚ from
upright, or vertical (refer to fig. 1). The arrows on
the valve identification label and on the bottom
plate indicate direction of gas flow through the
valve.
4. You should use new pipe that is properly cham-
fered, 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. 3 for typical piping connections).
6. Do not tighten piping excessively, as this may
damage the valve (50 ft lbs max).

7. See SYSTEM WIRING when making electrical
connections. After all gas and electrical connec-
tions 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.
LP GAS CONVERSION
For LP gas conversion, use the LP conversion kit
supplied with this control. Refer to the instruc-
tions packed with LP conversion kit.
PILOT GAS CONNECTION
These gas valves are shipped with the pilot outlet
plugged. For installations requiring pilot gas
(Proven/Intermittent Pilot Systems), remove the
plug from the pilot gas outlet (see fig. 2) and use
the fitting packed separately with the valve.
Install the fitting into the pilot gas outlet, turning
until finger tight. Insert clean, de-burred 1/4" O.D.
tubing all the way through the fitting. While hold-
ing the tubing securely, slowly tighten the fitting
until you feel a slight "give". Tighten the fitting an
additional 1-1/2 turns.
The plug should not be removed for a Direct
Burner Ignition system such as Direct Spark or Hot
Surface Ignition.
Refer to page 7 for pilot flame adjustment infor-
mation.
