gas control.
6. Check the regulator setting either with a manometer
or by clocking the gas meter. Refer to Startup and Check-
out.
7. Install the new cap screw.
8. Mount conversion label on control.
9. Install control and appliance according to appliance
manufacturer instructions.
INSTALL ADAPTERS TO GAS CONTROL
Install adapters to gas control as follows:
Flanges
1. Choose the appropriate flange for your application.
2. Remove seal over gas control inlet or outlet.
3. Ensure the O-ring is fitted in the flange groove. If the
O-ring is not attached or is missing, do not use flange.
4. With O-ring facing gas control, align the screw holes
on the control with the holes in the flange. Insert and tighten
the screws provided with the flange. See Fig. 3. Tighten the
screws to 25 inch-pounds of torque to provide a gas-tight
seal.
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 care-
fully into bushing until tight.
USING ADAPTERS TO SOLVE SWING RADIUS
PROBLEMS
In some field service applications, it is difficult or
impossible to thread the control onto the gas supply pipe
because of space limitations. This problem can be resolved
in many instances by using an adapter. The adapter in
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, corro-
sive 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
accumulation.
• Avoid locating gas control where exposure is pos-
sible 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 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, 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-tube coupling to connect the tubing
to the gas control.
3. Install sediment trap in the supply line to the gas
control. See Fig. 4.
