GAS VALVE

REGULATOR ADJUSTMENT

Recommended gas pressure at manifold 

(4.0" W.C. Natural gas 10.0" W.C. Propane gas)

Adjustment of the gas valve pressure regulator is not

normally necessary since it has been preset at the fac-

tory. During installation, the gas pressure should be

checked at each gas valve with all burners operating.

Adjustment may be accomplished as follows:

This adjustment must be performed by a qualified tech-

nician.

1. Locate the gas valves. 

2. With the griddle turned off, connect the monometer

to the pressure tap on the gas valve to be tested.

3. Turn the unit on and take the reading after all the

burners have ignited.

4. Make the necessary adjustments by removing the

screw cap on the pressure regulator cover exposing

the adjustment screw (clockwise will increase the

pressure, counterclockwise will decrease the pres-

sure).

Always check the screw cap on the pressure tap for

leaks after it has been removed and replaced.

GAS VALVE 

REMOVAL AND REPLACEMENT

Disconnect the griddle from the gas supply.

1.

Lower the control panel. Remove the control panel

surround and upper heat shield.

2.

Remove the three wires connected to the gas

valve.

3.

Disconnect the pilot and burner feed from the front

of the gas valve.

4.

Access the pipe union at the rear of the gas valve

either from the front of the griddle or remove the

back of the cabinet and loosen the union.

5.

Remove two nuts on the rear of the gas manifold

and pull the gas manifold forward.

6.

Remove the gas valve and transfer the pipe and fit-

tings to the new gas valve. Transfer the pressure

tap to the new gas valve.

7.

Replace the gas valve by reversing the above

steps.

Always check for leaks at all joints and connections

using a soap solution mixed with water. 

DO NOT USE AN OPEN FLAME TO CHECK FOR

GAS LEAKS. 

Double check the wire connections to the gas valve;

improper connection could damage the gas valve.

ON/OFF SWITCH 

REMOVAL AND REPLACEMENT

1.

Lower the control panel by removing the screws. 

2.

Disconnect the wires on the switch and remove

switch.

3.

Snap the new switch into place and reconnect all

wires.

4.

Return the control panel to its normal position.

THERMOSTAT 

REMOVAL AND REPLACEMENT

1.

Lower the control panel by removing the mount-

ing screws.

2.

Locate the bulb end of the thermostat and, using

a wrench, loosen the front and rear bolts holding

the thermostat bulb and shield in place.

3.

Slide the thermostat bulb assembly towards you

and remove it from under the griddle plate.

4.

Remove the knob and the screws from the ther-

mostat dial plate on the control panel.

5.

Remove the body of the thermostat.

6.

Install the new thermostat in the control panel,

replace the dial plate.

7.

Slide the thermostat bulb assembly into the

channel until it reaches the stop.

8.

Make sure that the thermostat capillary and bulb

are completely protected by the shield, except for

1” at the tip of the thermostat bulb. (See Note 1).

9.

Make sure that the thermostat shield extends to

the front edge of the plate, and that the capillary

goes through the formed end of the shield. (See

Note 2).

10.

Make sure that the bolts which hold the thermo-

stat bulb and shield in place do not touch the

thermostat bulb. (See Note 3).

Tighten bolts 1/4 turn past finger tight bulb to be

snug against the bottom of the plate.

DO NOT OVERTIGHTEN THE BOLTS ON THE

THERMOSTAT SHIELD OR THEY

WILL

CRUSH THE THERMOSTAT BULB.   

11.

Close the control panel and replace the panel

mounting screws.

NOTE: IF REPLACING PUSH-ON TERMINAL

STYLE.  Before installing thermostat into control

panel, you must unscrew the two brass terminal

screws and install the new ring terminal wire con-

nectors. Prior to connecting these wires, the

existing push-on terminal must be cut off and ring

terminals installed on them. Make sure that the

terminals are secured down.

12.

Calibrate the thermostat using an accurate grid-

dle thermometer. Locate the thermometer over

the thermostat bulb (shown by the "

Λ" on the

front of the griddle plate) about half way toward

the back of the plate. Calibrate to the cooking

temperature you will be setting on the thermo-

stat.
