• Cover gas control if appliance is cleaned with water,
steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating gas control where exposure to
corrosive chemical fumes or dripping water are likely.
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
com-ply with approved standards and practices.
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 Control
1.
This control can be mounted from 0 to 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 to 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. 3.
5.
Remove seals over control inlet and outlet if neces-
sary.
6.
Connect pipe to control inlet and outlet. Use
wrench on the square ends of the control. If a
flange is used, place wrench on flange rather than
control. Refer to Fig. 4 and 5.
Fig. 2. Install sediment trap.
Fig. 3. Use moderate amount of pipe compound.
