Bushings
1. Remove seal over gas control inlet or outlet.
2. Apply moderate amount of good quality pipe com-
pound to bushing, leaving two end threads bare. See Fig. 2.
3. Insert bushing in gas control and carefully thread pipe
into the bushing until tight.

pound.

LOCATION
Locate the combination gas control in the appliance
vestibule on the gas manifold. In replacement applications,
locate the gas control in the same location as the old control.
Do not locate the gas control where it can be affected by
steam cleaning, high humidity, dripping water, corrosive
chemicals, dust or grease accumulation, or excessive heat.
For proper operation, follow these guidelines:
• Locate gas control in a well-ventilated area.
• Mount gas control high enough above the cabinet bot-
tom to avoid exposure to flooding or splashing water.
• Make sure the ambient temperature does not exceed
the ambient temperature ratings for each component.
• Cover gas control when the appliance is cleaned with
water, steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating gas control where exposure to corro-
sive chemical fumes or dripping water is possible.
INSTALL PIPING TO GAS CONTROL
All piping must comply with applicable codes and ordi-
nances 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
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. 3.
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.
APPLY A MODERATE AMOUNT OF
PIPE COMPOUND TO PIPE ONLY
(LEAVE TWO END THREADS BARE).

3. Thread pipe the amount shown in Table 4 for insertion
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.

IS COMPLETE.
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. 2. On LP installations, 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. 4
and 5.
