3. Unscrew compression titling from the pilot outlet
(Fig. 4).
4. Slip the compression fitting over the tubing and
slide out of the way.
5. Push the tubing into the pilot gas tapping on the
outlet end of the control until it bottoms. While hold-
ing tubing all the way in, slide compression flitting
into place and engage threads—turn until finger
tight. Then tighten one more turn with a wrench. Do
not overtighten. Refer to Fig. 6.
6. Connect other end of the tubing to pilot burner
according to the pilot burner’s manufacturer’s
instructions.
NOTE: When replacing a gas control, cut off old com-
pression fitting and replace it with the new com-
pression fitting provided on the gas control.
Never use the old compression fitting as it may
not provide a gas-tight seal.
