INSTALLATION

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.

Fig. 2—Use moderate amount of pipe com-
pound.

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

into the gas control.

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.

IMPORTANT:

Do not thread pipe too far. Valve distortion

or malfunction can result when the pipe is inserted too
deeply into the gas control.

ALL BENDS IN METALLIC TUBING SHOULD BE SMOOTH.

CAUTION: SHUT OFF THE MAIN GAS SUPPLY
BEFORE REMOVING END CAP TO PREVENT
GAS FROM FILLING THE WORK AREA. TEST
FOR GAS LEAKAGE WHEN INSTALLATION
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.
