1.
Use new, properly reamed pipe free from chips. If
tubing is used, make sure the ends are square,
deburred and clean. Make sure all tubing bends are
smooth and without deformation.
2.
Run pipe or tubing to the gas control. If tubing is
used, obtain a tube-to-pipe coupling to connect the
tubing to the gas control.
3.
Install sediment trap in the supply line to the gas
control. See Fig. 2.
Install Gas Control
1.
This gas control can be mounted from 0 to 90
degrees in any direction from the vertical 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 5 for inser-
tion into the gas control.
IMPORTANT:
Do not thread pipe too far. Valve distortion or
malfunction can result when the pipe is inserted
too deeply into the gas control.
Fig. 2. Install sediment trap.
4.
Apply a moderate amount of good quality pipe com-
pound (do not use Teflon tape) to pipe only, leaving
two end threads bare. See Fig. 1. On LP installa-
tions, 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. See
Fig. 3 and 4.
When working with an intermittent pilot ignition system, go
to Connect Pilot Gas Tubing section next. When installing
on a hot surface or direct spark ignition system, go to the
Wiring section.
