MANUAL VALVE KNOB
The manual valve knob is a two-position (ON-OFF) type.
To turn manual valve on, rotate knob clockwise or coun-
terclockwise to line up the word ON on the knob with the
indicator on the cover casting (see fig. 5). To turn manual
valve off, rotate knob clockwise or counterclockwise to
line up the word OFF on the knob with the indicator on the
cover casting.

PILOT GAS ADJUSTMENT
These controls are factory preset to provide proper pilot
gas flow for most applications. If additional adjustment is
necessary, follow these steps.
1. Turn off all electrical power to the system before
making any adjustments.
2. Remove the pilot adjust cover screw and gasket to
expose the adjusting screw (see fig. 6). Turn the
adjusting screw clockwise to reduce pilot flame, or
counterclockwise to increase pilot flame.
3. Replace the gasket and pilot adjust cover screw and
tighten securely.
4. Restore power to the system.
PRESSURE REGULATOR
ADJUSTMENT
These controls are shipped from the factory with the
regulator set for 3.5” W.C. (natural gas, full flow). Consult
the appliance rating plate to ensure burner manifold
pressure should be 3.5” W.C. If another outlet pressure is
required, follow these steps.
If a valve has been factory-adjusted for the 2.5 to 5 inches
W.C. range, it cannot be field-adjusted outside that range.
This is also true for valves adjusted to the 7.5 to 12 inches
W.C. range for LP gas.
1. Turn off all electrical power to the system.
2. Attach a manometer to the outlet pressure tap of the
valve.
3. Turn on system power and energize valve.
4. Remove regulator cover screw and turn regulator
adjust screw clockwise to increase pressure, or
counterclockwise to decrease pressure (see fig. 6).
Always adjust regulator to provide the correct pres-
sure according to the original equipment
manufacturer’s specifications listed on the appliance
rating plate.
5. Replace regulator cover screw and tighten securely.
