control by following the same precautions and instruc-
tions that are used for installing the gas control. After the
adapter is installed, attach the gas control to the adapter as
outlined above. Note that using an adapter increases the
overall length of the gas control.
LOCATION
Mount the combination gas control in the appliance
vestibule on the gas manifold. If this is a replacement
application, mount 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.
To assure proper operation, follow these guidelines:
• Locate gas control in a well-ventilated area.
• Mount 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 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 corro-
sive chemical fumes or dripping water is possible.
Install Piping to Gas Control
All piping must comply with local 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, 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
including vertically, 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 4 for inser-
tion into gas control.
Do not thread pipe too far
. Valve
distortion or malfunction may result if the pipe is inserted
too deeply into the gas control. See Fig. 3.

4. Apply a moderate amount of good quality pipe
compound (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 gas control.
Refer to Figs. 4 and 5.
