Pilot Flame Adjustment
(Vented Units Only)
The pilot flow adjustment is preset to maximum at the factory.
The pilot flame should envelope ⅜ʺ to ½ʺ of the thermocouple
(see figure 22).
1. The adjustment screw can be reached through a hole in the
MANUAL knob (see figure 21).
2. Turn the MANUAL knob to the
ON
position.
3. It is now possible to pierce through a film on the cover with a
screwdriver to reach the adjustment screw beneath.
4. Turn the adjustment screw clockwise
to decrease or
counterclockwise
to increase pilot flame.
Outlet Pressure Adjustment
(Vented Units Only)
STANDARD REGULATOR OR THROTTLE
(Throttle CE Only)
1. Connect a pressure manometer to the valve outlet pressure
tap. Pressure tap is opened by turning the screw counterclock-
wise
.
Pressure regulator or throttle are located under the cover and
can be reached by removing the plug (see figures 21 and 23).
2. Turn MANUAL knob and main valve knob to the
ON
position.
3. Turn pressure regulator adjustment screw to set required
burner pressure (high fire). Pressure is increased by turning
clockwise
(pressure regulator models), or decreased by
turning counterclockwise
.

NOTE:

; or decreased by turning clockwise
.
4. After adjustment, replace the plug.
5. If no other adjustments are required, close pressure tap(s) by
turning the screw(s) full clockwise
.
Check all connections / pressure tap(s) for leaks.
6. If the desired outlet pressure or flow cannot be achieved by
adjusting the gas valve, check the gas valve inlet pressure us-
ing a manometer at the valve inlet pressure tap. If the inlet
pressure is in the normal range, replace the gas valve; other-
wise, take necessary steps to assure proper gas pressure to
the valve.
CONVERTIBLE PRESSURE REGULATOR
(CSA Only; Optional)
Convertible regulators are designed to deliver either of two fixed
outlet pressures for Natural Gas (NG) or LP Gas. To change
from one gas to the other, turn the conversion plug (see figure
24, page 14) counter clockwise to remove. Unsnap and remove
the plastic part, rotate it 180°, and then slide it back on the con-
version plug until it snaps. Turn the conversion plug clockwise
until it bottoms out.
Knob function as follows (see figure 21):

POSITION
FUNCTION
Main valve knob
OFF
Prevents main gas flow through valve.
Main valve knob
ON
Permits main gas flow through valve
if the pilot is lit and thermocouple is
generating sufficient power.
Manual knob

It is the appliance manufacturer’s responsibility to determine
GV60’s suitability for a specific application.
Do not attempt to remove screws from the top of gas valve.
Do not change any adjustments marked with tamper indicating
paint. Motor knob is not to be removed.
