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 a flange is
used, place wrench on flange rather than on gas control.
Refer to Figs. 4 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
because this can 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.
See Fig. 4. Slip the fitting over the tubing and slide out of
the way.
Fig. 5—Proper use of wrench on gas control with and without flanges.

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 because 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, engage
threads and 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 instructions.
