FLUE CONNECTIONS
Do not obstruct the flow of flue gases from the flue, located at the rear of the griddle. It is recommended that flue
gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.
From the termination of
the flue to the filters of the hood venting system, a minimum clearance of 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, Battery march 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.
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 (Fig. 2 on next page) and the regulator is positioned with the vent plug and conversion plug cover
upright (Fig. 3 on next page).
