gas control.
INSTALL BUSHINGS TO CONTROL
If adapters are to be installed on the gas control, mount
them as follows:
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. On LP
installation, use compound resistant to LP gas. Do NOT use
Teflon tape.
3. Insert bushing in gas control and thread pipe carefully
into bushing until tight.
Complete instructions below for piping, installing con-
trol, connecting pilot tubing, thermocouple and wiring. Make
certain the leak test you perform on the control after complet-
ing the installation includes leak testing the adapters and
screws. If you use a wrench on the valve after flanges are
installed, use the wrench only on the flange, not on the
control.
USING ADAPTERS TO SOLVE SWING RADIUS
PROBLEMS
In some field service applications, it is difficult or impos-
sible to thread the gas control onto the gas supply pipe
because of space limitations. This problem can be resolved in
many instances by using an adapter. The adapter is installed
on the end of the supply pipe in place of the gas control,
following the same precautions and instructions that are used
for installing the gas control. After the adapter is installed, the
gas control is attached to the adapter as outlined above. Note
that using an adapter increases the overall length of the gas
control.
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
ensure 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.
• Ensure 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 accu-
mulation.
• Avoid locating gas control near possible exposure to
corrosive chemical fumes or dripping water.
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 (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, ensure 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. 3.
