INSTALLATION, OPERATION AND CARE OF MEDIUM DUTY

GAS GRIDDLES

GENERAL

Medium Duty Gas Griddles are produced with quality workmanship and materials. Proper installation, usage
and maintenance of your griddle will result in many years of satisfactory performance.

Thoroughly read this entire manual and carefully follow all of the instructions provided.

INSTALLATION

UNPACKING

This griddle was inspected before leaving the factory. The transportation company assumes full responsibility
for safe delivery upon acceptance of shipment. Check for possible shipping damage immediately after
unpacking. If the griddle is found to be damaged, save the packaging material and contact the carrier within 15
days of delivery.

Carefully unpack your griddle and make sure that no parts are discarded with packaging material. A pressure
regulator designed to operate with the griddle has been supplied and must be installed before the griddle is
placed into service (Refer to GAS PRESSURE REGULATOR INSTALLATION in this manual).

LOCATION
The installation location must be kept free and clear of combustibles. When installing, never enclose the bottom

of the griddle with a raised curb or other constructions that would obstruct flow of air into or out of the griddle.
Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an
adequate supply of air in the room to replace air taken out by the ventilation system.

Do not permit air to blow directly at the griddle. Avoid open windows next to the griddle wherever possible. Avoid
wall-type fans which create air cross-currents within the room.

This griddle is Design Certified for installation on a non-combustible counter with 4” legs, or combustible floor
with 24” high stand.

In Canada:
1 Local codes.

2 CAN/CSA-B149.1 Natural Gas Installation (latest edition)
3 CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the Canadian Gas
Association, 178 Rexdale Blvd., Etobicoke, Ontario, Canada M9W 1R3

GRIDDLES MOUNTED ON STANDS WITH CASTERS
Griddles mounted on stands with casters must use a flexible

connector (not supplied) that complies with the Standard for

Connectors for Movable Gas Appliances ANSI Z21.69•CSA6.16, and

a quick-disconnect device that complies with Gas Fuel, ANSI

Z21.3•CSA6.9. In addition, adequate means must be provided to limit

movement of the appliance without depending on the connector and
the quick-disconnect device (or its associated piping) to limit
appliance movement. Attach the restraining device at the rear of the
griddle as shown in Fig. 1.

Fig. 1

If disconnection of the restraint is necessary, turn off the gas supply before disconnecting. Reconnect the
restraint prior to turning the gas supply on and returning the griddle to its installation position.

Casters are only supplied on a griddle stand. If the griddle is moved for any reason the griddle should be
re-leveled (see LEVELING in this manual).

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).
