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 connectors. Prior to connect-
ing 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.
5. Calibrate the thermostat using an accurate griddle
thermometer. Locate the thermometer over the
thermostat bulb (shown by the "L" 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 thermostat.
B. REMOVAL AND REPLACEMENT OF SPARK MODULE
The spark module quickly lights the pilot then the
burner when the thermostat calls for heat. It also has a
“proof of fl ame” feature which will sense if the pilot has
gone out and will automatically relight it. There is also a
green LED light for troubleshooting assistance. If power
is on and the LED is off, then the spark module needs
to be replaced.
NOTE:
Power to the spark module is 24 VAC.
REMOVAL:
1. Disconnect electric power source.
2. Turn off gas.
3. Remove spark module located on rear or under
griddle. If mounted under griddle, remove cover.
4. Remove cover.
5. Disconnect spark module wires, carefully noting
connections.
6. Remove faulty spark module from spark module
box by removing four machine screws and nuts.
REPLACEMENT:
1. Replace spark module with four machine screws
and nuts.
2. Reconnect spark module wires, checking connec-
tions to appropriate wiring diagram for your griddle on
pages
16 to 21.
3. Reconnect electric power source.
4. Turn on gas.
See page 5 - LIGHTING.
C. REMOVAL AND REPLACEMENT OF GAS VALVE
The gas valve provides an adjustable regulated gas sup-
ply to the burners and pilots.
NOTE:
Gas valve operates on 24 VAC.
1. Disconnect electric power source.
2. Turn off gas.
3. Remove control panel by removing four screws
and support it to prevent damage to wiring or other
components.
4. Disconnect wires from gas valve, carefully noting
connections.
5. Remove burner tubing compression connector(s)
and tubing from gas valve.
6. Unscrew gas valve from gas manifold behind it.
NOTE:
Sealing tape or a compound designed for gas
G30 and G31 connections should be applied to all pipe
connections.
REPLACEMENT:
1. Carefully screw inlet port of new gas valve onto gas
manifold.
2. Replace burner tubing compression connector(s)
and tubing into outlet port(s) of new gas valve.
3. Reconnect four wires to gas valve, checking con-
nections to appropriate wiring diagram for your griddle
on pages
16 to 21.
4. Replace control panel with four screws.
5. Reconnect electric power source.
6. Turn on gas and test for leaks using soap and
water solution (or sniffer). Never use a match or other
open fl ame to check for leaks.
See page 5 - GAS
LEAK TESTING.
7. Turn on pilots (see page 5). Check pilot fl ame to
ensure electrode is heated well enough to allow burn-
ers to come on. See page 12 - FLAME ADJUSTMENT.
8. Remove allen head test plug on left back side of
gas valve and use manometer to test burner gas.
Adjust burner gas pressure as needed and adjust
fl ame height to 25mm to 38mm below bottom of
griddle plate. See FLAME ADJUSTMENT.
D. REMOVAL AND REPLACEMENT OF SPARK
ELECTRODE
The spark electrode, when energized by the spark mod-
ule, quickly lights the pilot. It also senses the presence
of fl ame once the pilot is lit.
REMOVAL:
1. Disconnect electric power source.
2. Turn off gas.
3. Remove control panel by removing four screws
and support the panel to prevent damage to wiring or
other components.
4. Carefully pull off electrode wire from spark module
(See page 11 - REMOVAL OF SPARK MODULE).
5. Remove pilot orifi ce from pilot by loosening the
compression fi tting on bottom of pilot.
6. Remove pilot assembly and ground wire by remov-
ing one screw. Spark electrode and electrode wire
are permanent parts of the pilot assembly - must
replace pilot assembly to replace electrode and wire.
