INSTALLATION INSTRUCTIONS
IMPORTANT
Read these instructions carefully before starting the installation. Upon receipt of your equipment,
thoroughly inspect it for any damage. If any damage is noted, immediately file a claim with the trucking
company. Failure to contact the trucking company immediately may result in their refusal of your claim.
After checking for damage, examine the markings on the equipment to ensure that the type of gas is
correct.
INSTALLATION
A qualified installer, service agency or gas supplier must perform installation and service.
Provisions shall be made to the design of the kitchen to ensure an adequate supply of fresh air for
proper combustion.
It is suggested that for servicing and proper operation, a free area of at least 36 inches be provided to
the front of the appliance.
The installation must conform with local codes, or in the absence of local codes, in the USA, to the
National Fuel Gas Code, ANSI Z223.1-latest edition, and in Canada, CAN/CGAB149.1 and
CAN/CGA-B149.2 — Installation Code for Gas Burning Appliances and Equipment.
Level the appliance. Adjustable legs are provided. If the appliance is equipped with casters, the
installation shall be made with a connector that complies with the Standard for Connectors for
Movable Gas Appliances, ANSI Z21.69-latest edition, and a quick-disconnect device that complies
with the Standard for Quick-Disconnect Devices for Use with Gas Fuel, ANSI Z21.41-latest edition.
In Canada, the flexible connector must be CGA approved and comply with the CAN 1.6.10-88. Quick
disconnect must comply with CAN1 6.9.M79.
Adequate means must be provided to limit the movement of the appliance without depending on the
connector and the quick-disconnect device or its associated piping to limit the appliance movement.
The restraining means may be attached to the rear of the appliance by cable.
The input rating of your equipment is for elevations up to 2,000 feet. For elevations above 2,000 feet,
the rating must be reduced by 4% for every 1,000 feet above sea level.
This appliance shall be installed with the following minimum clearances from adjacent constructions:
The appliance shall be installed on non-combustible counters. When equipped with high legs, with or
without casters, the appliance may be installed on combustible floors.

GAS PIPING
A regulator is provided with this appliance set a 5” W.C. for Natural Gas or 10” W.C. for propane gas.
A conveniently located gas shutoff valve, external to the appliance, is required for complete shutdown.
Be sure all valves are in a closed position before connecting to gas supply.
Connect the appliance to gas supply line. Under no circumstances should the gas supply line be
smaller than the inlet pipe on the appliance. Use pipe compound on all pipe joints. Compound must be
resistant to the action of liquefied petroleum gases.
Check all gas connections for leaks using a soap and water solution. DO NOT USE AN OPEN
FLAME FOR CHECKING PURPOSES.
The appliance must be isolated from the gas supply system. This is done by closing its individual
manual shutoff valve during any pressure testing of the gas supply piping system at test pressures
equal to or less than ½ psig (3.45 kPa).
The appliance and its shutoff valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in excess of ½ psig (3.45 kPa).
NOTE*: Your appliance was tested, rated and adjusted at the factory before shipment and should be
ready for use at the site without any major adjustments.
NOTE**: The models JGT, JGTS, JGTSD, JGTSDS , JGGT and JGGTS are thermostatically controlled and,
although the thermostats are factory calibrated and tested, conditions at the site, such as unbalanced units
(e.g., not level, low gas pressure, incorrect air flow in hood systems, blocked flue, etc.) may cause poor
combustion and an apparent reduction in heat on griddle plate.
These conditions should be corrected before attempts are made to re-calibrate the thermostats.
(CALIBRATION SHOULD BE PERFORMED BY A QUALIFIED PERSON.)
LIGHTING AND RELIGHTING INSTRUCTIONS
Hot Plates:
Your appliance is equipped with constantly burning pilots. Turn valves. Adjust lighter flames by using a
screwdriver to turn lighter valve screw clockwise or counter-clockwise. Turn burner valves “ON.” If lighter
flames go out, turn off valves and repeat above procedure.
