Installation
18” must be maintained. Information on the construction and installation of ventilating hoods may be obtained
from the standard for “Vapor Removal from Cooking Equipment”, NFPA No. 96 (latest edition), available from
the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
GAS CONNECTIONS
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
Use a ¾” NPT gas supply line for the griddle inlet, located at the rear of the griddle. All of flexible and semi-rigid
gas supply lines must comply with the applicable ANSI standard. To ensure maximum operating efficiency, this
appliance must be connected with a gas supply line of solid pipe or a commercial type Flexible Connector with
the net inside diameter (I.D.) as large as or larger than the gas pipe inlet on this appliance. Codes require that
a gas shutoff valve must be installed in the gas line upstream of the griddle.
Warning: Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution.
Do not use an open flame.
After checking for leaks all lines receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When the gas supply pressure exceeds ½ psig (3.45 kPa), the griddle and its individual shutoff valve must be
disconnected from the gas supply piping system. When the gas supply pressure is ½ psig (3.45 kPa) or less,
the griddle should be isolated from the gas supply system by closing its individual manual shutoff valve.
GAS PRESSURE REGULATOR INSTALLATION
This griddle is supplied with a convertible gas pressure regulator preset at 4” Water Column (W.C.) for natural
gas. No further adjustment should be required. Install the regulator as close to the griddle on the gas supply
line as possible. Make sure that the arrow on the underside of the regulator is oriented in the direction of gas
flow to the griddle and the regulator is positioned with the vent plug and conversion plug cover upright. The
supply pressure (upstream of the regulator) should be 7-9” W.C. for natural gas and 11-12” W.C. for propane
gas. At no time should the griddle be connected to supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.
PROPANE GAS CONVERSION
This griddle is shipped from the factory equipped with fixed burner and pilot orifices for natural gas operation.
The burner and pilot orifices required to convert the griddle to propane gas are shipped with the griddle in
the shipping packaging. It is recommended that a trained gas service technician with the necessary tools,
instruments and skills perform the conversion.
To convert to propane, following steps must be completed:
Remove all natural gas burner orifices and install the provided propane burner orifices. See Fig. 4.
1.
Remove all pilot orifices and install the provided propane pilot orifices. See Fig 4.
