Lighting & Pilot Burner Adjustment
Each griddle burner is equipped with a pilot.
For the HI-LO valve operated model, the pilot adjusting
valve burner pilot is located on the manifold to the
right of each griddle valve. Open the pilot valve with a
screwdriver and light the pilot with a match.
For the griddle equipped with thermostats (GTHX) the
pilot is located to the left of the ON-OFF valve. Open
the pilot valve with a screwdriver and light the pilot
with a match.
Pilots flames must be / inch (mm) long .
Hi-Lo Valve Adjustment
Griddles equipped with Hi-Lo valves require a low flame
setting. To adjust, proceed as follows:
4. With a screwdriver, turn the small adjusting screw
inside the valve stem and adjust to obtain the low
cooking temperature desired, maintaining a stable
flame covering the entire burner (minimum 3/16
inch (5 mm) long flame)).
5. Replace dial and turn to “OFF” position.
Calibration Instructions
1. Use a test instrument with a special disc type
thermocouple or a reliable surface type pyrometer.
Note: a drop of oil on the face of the disc will
provide better contact with the plate.
2. Set all griddle thermostats to 350°F. In order to
allow the griddle temperature to stabilize, the
thermostats must be allowed to cycle twice before
taking a test reading.
3. Check the griddle temperature when the thermostat
just cycles “OFF” by placing the thermocouple
firmly on the griddle surface directly above the
sensing bulb of the thermostat. e reading should
be between 335°F and 365°F. If the reading is
outside of these limits, calibrate as follows:
4. Carefully remove the dial, not disturbing the shaft
position.
5. Hold the shaft steady and with a small flat screw
driver turn the calibration screw located inside
the shaft clockwise to decrease temperature or
anti-clockwise to increase temperature. Note:
Each 1/4 turn of the screw will create a change of
approximately 25°F.
6. Replace the thermostat dial and repeat steps 1
through 3 to verify that a correct adjustment has
been made.
1. Burner must be cold.
2. Be sure pilot flames are lit and adjusted.
3. Turn dial to “LO” position, then remove dial.

1. e pilot adjusting valve is located on the
manifold.
2. With valve panel in place, the pilot can be adjusted
with a long thin screwdriver to obtain a 7/16 inch
(11 mm) long flame. (is adjustment can be made
through the small hole located on the valve panel.)
G-SPH Stock Pot Range
is stock pot range is equipped with an automatic safety
pilot system. Should the pilot go out, the main burner
gas supply is automatically shut off. To light and adjust
the pilot:
1. Remove the valve panel if not already removed.
2. Depress the red button of the automatic pilot valve
and light pilot.
3. Hold red button depressed for one minute after
pilot has been ignited.
4. Adjust pilot flame to a 7/16 inch (11 mm) long
flame.
5. If pilot does not continue to burn after releasing
button, repeat above procedure or …
6. Have a qualified serviceman check the system. Do
not allow anyone else to attempt repairs.
7. Once the pilot is lit it is not necessary to repeat
lighting procedure, unless the pilot is extinguished
for any reason.
Hi-Med-Lo Valves
e G-SP and G-SPH stock pot ranges are equipped
with Hi-Med-Lo valves. No adjustment is necessary.
A pressure tap is supplied with the unit and it is installed
on the manifold, downstream of the main valve. e gas
pressure must be checked when the unit is installed, to
ensure that the unit gas pressure is the same as specified
on the rating plate. If necessary, pressure adjustments,
must be made at the pressure regulator.
Lighting Standing Pilots - All Models
ese units are not designed to be disconnected from
their gas connections and re-installed on a regular basis.
Quick connect gas lines should not be used. Once the
gas appliance has been installed by a licensed gas tradesperson all connections, pilot lights and controls have
been inspected for proper operation. All gas appliances
that use standing pilot systems are generally assumed to
be operating with the pilot on continuously. e units
should not be restarted except in the event of a gas service
interruption to the facility.
If a pilot flame does go out, here are the basic steps to
check before you re-light the pilot:
1. Check to see that all gas lines are in place and
secured and that there is no accumulation of gas
inside the unit.
2. Check to make sure that the main shut off valve is
in the off position.
3. Turn the thermostat to the off position. (If
applicable)
4. Turn on or open the main shut off valve to the
appliance.
5. Depending on the appliance type:
Lower the front black enamel panel to the unit
and immediately depress the red button, which
is the piezo to ignite the pilot.
Or.
Remove the front valve panel and light the
pilot with a lighted taper, through pilot viewing
hole.
Part #P65 (11/05)Page 9
OPERATION continued
6. e pilot should ignite within a few attempts.
You will be able to see the pilot flame through the
observation hole in the stainless steel front panel.
7. If you do not have a pilot flame established fairly
quickly and begin to smell gas, shut off the main
valve and wait five minutes to let the gas build-up
escape.
8. Only once the pilot flame has been established
should you turn on the burner control. When the
burner control is on it allows gas flow to the burner.
If there is no pilot flame it will allow gas to build
up and cause possible delayed ignition, which could
result in an explosion.

Operating Suggestions
1. Avoid the use of oversized pots.
2. Avoid spillovers
3. Covered pots will boil faster
Griddle Top
Seasoning – Before being used for the first time, all
griddle surfaces must be seasoned. Was the griddle with a
hot detergent or soap solution, rinse and dry thoroughly.
Set the Griddle heat to the lowest possible temperature
for minutes. Apply a thin film of cooking oil. Allow
the oil to remain on the griddle for minutes and then
wipe off. Rest the heat to medium temperature and apply
a second film of oil. Wipe off excess after minutes.
Rest the heat to the cooking temperature and apply a
final film of oil, wiping off excess after minutes. e
griddle is now seasoned and ready for use. e griddle
may be re-seasoned at any time by cleaning thoroughly
and following the seasoning procedure.
Cleaning. – Griddle plates should be wiped daily while

griddle surface, rinse and dry thoroughly. Re-season the
griddle.
Stock Pot Ranges
Cast Iron Top – When cast iron tops (which are covered
in grease) arrive at the end users, the following seasoning
and care is recommended.
1. Wash the top grates with hot mild detergent or soap
solution. Dry thoroughly, rub with vegetable oil on
all exposed surfaces in the direction of the grain.
2. Soiled and burnt deposits can be removed with a
wire brush. Difficult to remove burnt deposit can
usually be removed using an oven cleaner. Wash,
dry thoroughly, then rub with vegetable oil.
3. Continuing this procedure will prohibit the
development of rust and will eventually form a
non-stick surface, with the caramelization of oil on
the cast iron top grates.
