CHOOSE GAS CONTROL LOCATION
Do not locate the gas control where it may be affected by
steam cleaning, high humidity, dripping water, corrosive
chemicals, dust or grease accumulation, or excessive heat.
To assure proper operation, follow these guidelines:
• Locate gas control in a well-ventilated area.
• Mount the gas control high enough above the cabinet
bottom to avoid exposure to flooding or splashing
water.
• Assure the ambient temperature does not exceed the
ambient temperature ratings for each component.
• Cover the gas control if 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 likely.
Locate the gas control in the appliance vestibule on the
gas manifold. In replacement applications, locate the gas
control in the same location as the old gas control.
Install Piping to Gas Control
All piping must comply with local codes and ordinances
or with the National Fuel Gas Code (ANSl 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, assure the ends are square, deburred and clean.
All tubing bends must be 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. Mount the gas control 0-90 degrees, in any direction
from the upright 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 insertion
into gas control.
IMPORTANT: Do not thread pipe too far. Valve distortion
or malfunction may result if the pipe is inserted too
deeply into the gas control. Refer to Fig. 3.

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.
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. If an adapter is
used, place wrench on adapter rather than on gas control. See
Figs. 4 and 5.
