INTRODUCTION
Rating Plate
When corresponding with the factory or your local
authorized factory service center regarding service problems
or replacement parts, be sure to refer to the particular unit
by the correct model number (including the pre x and su x
letters and numbers) and the warranty serial number. The
rating plate a xed to the unit contains this information.
The rating plate is visible by removing the lower front panel
on the G22 Series, the drip tray on the G24 Series or the valve
panel on the G20 Series.
INSTALLATION
We suggest installation, maintenance and repairs should be
performed by your local authorized service agency listed in
your information manual pamphlet.
In the event you have any questions concerning the
installation, use, care or service of the product, write or call
our Product Service Department.
This product must be installed by professional personnel as
speci ed. Garland/U.S. Range products are not approved or
authorized for home or residential use, but are intended for
commercial applications only. Garland / U.S. Range will not
provide service, warranty, maintenance or support of any
kind other than in commercial applications.
General Information
1. Damage check: check carton or crate for possible damage
incurred in shipping. After carefully uncrating, check for
“concealed” damage. Report any damage immediately to
your carrier.
2. Carefully remove unit from carton or crate. Burner tie
wires and other packing material should be removed
from units. On stainless steel and brushed units, the
protective material covering the stainless steel should be
removed immediately after the unit is installed.
3. Remove valve panels, top grates or fry tank and place in a
safe area to prevent damage.
4. Should it be necessary to remove the steel griddle plate
on units equipped with griddle thermostat, the griddle
thermostat bulb and capillary must rst be withdrawn
from the bulb shield assembly, located on the underside
of the griddle plate. This can be accomplished with the
griddle front raised and supported by the griddle prop
located on the underside of the griddle plate. Loosen the
four pal nuts securing the bulb shield assembly to the
griddle plate and withdraw the griddle thermostat bulb.
5. When a griddle plate is being installed on units equipped
with griddle thermostats, the thermostat bulb must
be inserted in the groove between the plate and the
bulb shield assembly. This can be accomplished with
the griddle front raised and supported by the griddle
prop, located on the underside of the griddle plate. It is
important for accurate temperature control that the bulb
be located inside the groove. Tighten the four pal nuts
securing the bulb shield assembly to the griddle plate.

The importance of proper installation of commercial
gas cooking equipment cannot be overstressed. Proper
performance of the equipment is dependent, in great part,
on the compliance of the installation with the manufacturer’s
speci cations. In addition compliance with the National
Fuel Gas code ANSI Z 223.1-1988/NFPA and/or Local Code is
required to assure safe and e cient operation.
In Canada, the installation and connection must comply with
CAN/CGA – B149 Installation codes and local codes where
applicable.
All burner adjustments and setting shall be made by a
quali ed gas technician.
1. The correct type of gas for which the unit was
manufacture is noted on the rating plate, and this type of
gas must be used.
2. The required manifold gas pressure for normal operation
is 7” water column for use on Natural gas and 11”
water column for use on Propane gas, unless speci ed
di erently on the rating plate.
3. Have a quali ed gas technician check the gas pressure
to make certain that existing gas facilities (meter, piping,
etc.) will deliver the BTU’s of gas required at the unit with
no more than 1/2” water column pressure drop. When
checking pressure, be certain that all the equipment on
same gas line is turned to the “ON” position.
4. Make certain that new piping, joints and connections
have been made in a clean manner and have been
purged, so that the piping compound, chips, etc., will not
clog pilots valves, and / or controls. Use pipe joint sealant
that is CGA approved for use with lique ed petroleum gas.
5. WARNING: Check gas connections for leaks, using soap
solution or similar means. DO NOT CHECK WITH AN OPEN
FLAME.
The appliance and its individual shuto valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at pressures in excess of
1/2 PSIG (3.45 KP2).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shuto valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less then 1/2 PSIG (3.45 KP2)

OPERATION
Hot Plate – Model G24-15H
Pilot Burner Adjustment
1. Remove ring grates and top grate, if not already removed.
2. Adjust the pilot valve, located on the manifold between
the two burner valves, to a yellow ame 1/2 inch (13 mm)
long (This adjustment can be made through the opening
in the upper front panel, around the rear burner valve.)
3. Replace ring grates and top grate.
To Operate Main Burner
1. Hi-speed non-clog burners light automatically from the
pilot.
2. Turn left valve full “ON” to light front burner. Turn right
valve full “ON” to light rear burner.
G24 Griddles
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.
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 rmly on the
griddle surface directly above the sensing bulb of the
thermostat. The 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 at 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.
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 ames must be 3/4 inch (19mm) long .
Hi-Lo Valve Adjustment
Griddles equipped with Hi-Lo valves require a low ame
setting. To adjust, proceed as follows:
1. Burner must be cold.
2. Be sure pilot ames are lit and adjusted.
3. Turn dial to “LO” position, then remove dial.
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 ame covering
the entire burner (minimum 3/16 inch (5 mm) long
ame)).
