6. Check the regulator setting either with a manometer or
by clocking the gas meter. Refer to Start-Up and Checkout on
page 8.
7. Install the new cap screw.
8. Mount conversion label on control.
9. Install control and appliance according to appliance
manufacturer's 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 groove of flange. 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. 4. 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 carefully thread pipe
into bushing until tight.

PROBLEMS
In some field service applications, it is difficult or impos-
sible to thread the control onto the gas supply pipe because of

space limitations. This problem can be resolved for most
installations 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 can 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 where exposure is possible
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
