Install Piping to Gas Control
All piping must comply with local codes and ordinances or
with the National Fuel Gas Code (ANSI Z223.1 NFPA No. 54),
whichever applies. Tubing installation must comply with
approved standards and practices.
1. Use new, properly reamed pipe free from chips. If tub-
ing is used, make sure the ends are square, deburred
and clean. All tubing bends must be smooth and with-
out deformation.
2. Run pipe or tubing to the control. If tubing is used,
obtain a tube-to-pipe coupling to connect the tubing to
the control.
3. Install sediment trap in the supply line to the gas con-
trol. See Fig. 3.
Install Control
1. This control can be mounted 0-90 degrees, in any
direction, from the upright position of the gas control
knob, including vertically.
2. Mount the control so gas flow is in the direction of the
arrow on the bottom of the control.
3. Thread pipe into control. Do not thread pipe too far.
Valve distortion or malfunction may result if the pipe is
inserted too deeply. Refer to Table 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. See Fig. 4.
Fig. 4. Use moderate amount of pipe compound.
5. Remove seals over control inlet and outlet if necessary.
6. Connect pipe to control inlet and outlet. Use wrench on
the square ends of the control. If an adapter is used,
place wrench on adapter rather than on control. Refer
to Fig. 5 and 6.
