nances, and/or national fuel gas codes.
1. Turn o electrical power to the system at the fuse
box or circuit breaker. Also turn o 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
(see g. 1). The arrow on
the valve indicates the direction of gas ow
through the control.
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 teon
tape that is approved for all gases, only to the
male threads of the pipe joints. DO NOT apply
compound or teon tape to the rst two threads
(see g. 3 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 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.

PILOT GAS CONNECTION
Install the tting into the pilot gas outlet (see
g. 4), turning until nger-tight. Insert clean,
deburred tubing all the way through the tting.
While holding the tubing securely, slowly tighten
tting until you feel a slight “give”. Tighten the
tting an additional 1-1/2 turns.
Refer to page 5 for pilot gas adjustment information.
