SPECIAL INSTRUCTIONS FOR WHITE RODGERS 36G22
GAS VALVE ADJUSTMENT

OUTLET PRESSURE
REGULATOR ADJUSTMENT
These controls are shipped from the factory with the regulator
set as specified on the control label.

Consult the appliance rating plate to ensure burner manifold
pressure is as specified.  If another outlet pressure is
required, follow these steps.

36G22M  Model (standard)

This has a range of adjustment of 2.5 - 5.0 inches W.C. for
NATURAL gas or 7.0 - 12.0 inches W.C. for LP gas.

36G22M  Model (limited adjustment)

This valve cannot be adjusted beyond reg. setting specified
on the control label.

REFER to valve control label for reg. or manifold pressure
setting.

1. Turn off all electrical power to the system.
2. Using a 3/32 inch hex wrench, loosen outlet pressure

tap screw (located in outlet pressure boss, see fig. 1)
one turn (screw need not be removed).

3. Attach a 5/16 inch hose and manometer to the outlet

pressure boss of the valve (see fig. 1).  Hose should
overlap boss 3/8 inch.

4. Turn on system power and set thermostat to call for

heat.

5. Using a leak detection solution or soap suds, check for

leaks at hose connection.  Bubbles forming indicate a
leak.  SHUT OFF GAS AND FIX ALL LEAKS
IMMEDIATELY.

6. Remove regulator cover screw and turn regulator adjust

screw clockwise (
