69-2253—07
CAUTION
Equipment Damage Hazard.
Can burn out thermostat or transformer.
Applying a jumper across (or shorting) the
valve coil terminals, even temporarily, can burn
out the thermostat or transformer.
Follow the appliance manufacturers instructions if
available; otherwise use these instructions as a guide.
IMPORTANT
These gas controls are shipped with protective
seals over the inlet and outlet tappings. Do not
remove the seals until ready to install adapters
or connect the piping.
Install Bushings To Control
If bushings are being installed on the control, mount
them as follows:
Bushings
1.
Remove the seal over the control inlet or outlet.
2.
Apply a moderate amount of good quality pipe
compound to the bushing, leaving two end
threads bare. On an LP installation, use
compound that is resistant to LP gas. See Fig. 1.
NOTE:
Do not use Teflon tape.
3.
Insert the bushing in the control and carefully
thread the pipe into the bushing until tight.
Complete the instructions below for installing the
piping, installing the control, and connecting the
wiring. Make sure the leak test you perform on the
control after completing the installation includes leak
testing the bushings.
Location
The gas controls are mounted 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.
Locate the combination gas control where it cannot be
affected by steam cleaning, high humidity, or 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 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
corrosive chemical fumes or dripping water are
likely.
Install Piping to 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 comply with approved standards
and practices.
1.
Use new, properly reamed pipe that is free from
chips. If tubing is used, make sure the ends are
square, deburred and clean. All tubing bends
must be smooth and without deformation.
2.
Run pipe or tubing to the control. If tubing is
used, obtain a tube-to-pipe coupling to connect
the tubing to the control.
3.
Install a sediment trap in the supply line to the
control. See Fig. 2.
Install Control
1.
Can be mounted in any direction.
2.
Mount so the gas flow is in the direction of the
arrow on the bottom of the control.
NOTE:
Gas valve will leak if installed backwards.
3.
Thread the pipe the amount shown in Table 5 for
insertion into control or adapters. Do not thread
pipe too far. Valve distortion or malfunction can
result if the pipe is inserted too deeply.
4.
Apply a moderate amount of good quality pipe
compound (do not use Teflon tape) only to the
pipe, leaving two end threads bare. On LP
installations, use a compound resistant to LP
gas. See Fig. 1.
5.
Remove the seals over the control inlet and out-
let if necessary.
6.
Connect the pipe to the control inlet and outlet.
Use a wrench on the hex end of the control. See
Fig. 3.
