INSERTION INTO GAS CONTROL
1. Mount the gas control 0-90 degrees, in any direction
including vertically, from the upright position of the gas
control knob.
2. Mount the gas control so gas flow is in the direction of
the arrow on the bottom of the gas control.
3. Thread pipe the amount shown in Table 4 for insertion
into gas control. DO NOT THREAD PIPE TOO FAR. Valve
distortion or malfunction may result if the pipe is inserted too
deeply into the gas control. Refer to Fig. 4.

4. Apply a moderate amount of good quality pipe com-
pound (DO NOT use Teflon tape) to pipe only, leaving two
end threads bare. On LP installations, use compound resistant
to LP gas.
5. Remove seals over gas control inlet and outlet if
necessary.
6. Connect pipe to gas control inlet and outlet. Use
wrench on the square ends of the gas control. If an adapter is
used, place wrench on adapter rather than gas control. Refer
to Figs. 1 and 5.

Connect Pilot Gas Tubing
1. Cut tubing to desired length and bend as necessary for
routing to pilot burner. Do not make sharp bends or deform
the tubing. Do not bend tubing at gas control or pilot burner
after compression fitting has been tightened, as this may
result in gas leakage at the connection.
2. Square off and remove burrs from end of tubing.
3. Unscrew compression fitting from the pilot outlet (Fig.
1). Slip the compression fitting over the tubing and slide out
of the way.

NOTE: When replacing a gas control, cut off old compres-
sion fitting and replace with the new compression fitting
provided on the gas control. Never use the old compres-
sion fitting as it may not provide a gas-tight seal.
4. Push tubing into the pilot gas tapping on the outlet end
of the control until it bottoms. While holding tubing all the
way in, slide compression fitting into place and engage
threads—turn until finger tight. Then tighten one more turn
with wrench. Do not overtighten. Refer to Fig. 6.
5. Connect other end of tubing to pilot burner according
to pilot burner manufacturer's instructions.
