Emerson White-Rodgers 36C03 Instructions D'installation page 3

MAIN PIPING CONNECTIONS
All piping must comply with local codes, ordi-
nances, 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 (see fig. 1). The arrow on
the valve indicates the direction of gas flow
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 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. 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 fitting into the pilot gas outlet (see
fig. 4), 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 1-1/2 turns.
Refer to page 5 for pilot gas adjustment information.
