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.
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.
PILOT GAS CONNECTION
Install fitting into pilot gas outlet (see fig. 2), 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
