INSTALLATION (continued)

DANGER:

FIRE AND

EXPLOSION HAZARD

NEVER use an open flame to check for gas leaks. Fire and explosion may result.

IMPORTANT:

All pipe joints must be checked for leaks before lighting. Leak checks should be performed with a soap and water solution.

WARNING:

FIRE HAZARD

This griddle is supplied with a gas pressure regulator. Failure to properly install the supplied regulator will result in an extremely hazardous condition.

Flow arrow stamped on body of regulator must point toward the griddle.

Regulator adjusting screw and vent hole must point UP.

IMPORTANT:

Verify fuel gas type. If the available fuel does not match the nameplate specification, exchange the griddle for the correct type. DO NOT attempt to modify a unit in the field to accept a different fuel.

IMPORTANT:

Avoid damage to the regulator: if the gas supply piping system is pressure tested at pressures exceeding 1/2 psig (3.45kPa) , the griddle must be isolated or disconnected from the gas piping system for the duration of the test.

INSTALLING THE GRIDDLE

Refer to the nameplate. Verify the fuel type and pressure, which must match the nameplate specifications. Connecting the griddle to the wrong fuel type and/or pressure will compromise the safety and/or performance of the appliance.

The griddle must be placed in its final operational position and leveled front-to-backandside-to-side,with a spirit level, prior to beginning the gas piping installation.Re-checkthe level of the unit at the conclusion of the gas piping installation.

Each gas griddle is supplied with a separate gas pressure regulator. The supplied regulator must be used, and must be installed on the manifold pipe protruding from the rear of the griddle. Ensure that the regulator is installed such that the flow arrow stamped on the body of the regulator points toward the griddle. Failure to properly install the supplied regulator will result in an extremely hazardous condition.

A moisture trap (drip leg) consisting of a tee, 4” nipple pointing down, and cap must be installed upstream of the gas pressure regulator.

A manual gas shut-offvalve may be required by local codes and is, in any case, strongly recommended. Theshut-offvalve must be installed between the gas supply piping and the gas pressure regulator.

It is the responsibility of the gas piping installer to identify the code requirement for a shut-offvalve.

Shut-offvalves, moisture trap and all associated piping must be supplied by the gas piping installer.

INSTALLATION (continued)

GAS PIPE PRESSURE TESTING

The main piping system must be capable of supplying the griddle with sufficient volume/flow of fuel to satisfy the maximum operational input requirements.

Make sure the supply piping system has been pressure tested before the regulator and griddle are connected. If the system must be re-tested,be sure the regulator is isolated by a manualshut-offvalve, in order to prevent damage to the regulator and gas griddle valves.

Piping and connections should be leak tested using a water/soap solution. DO NOT USE FLAME TO CHECK FOR GAS LEAKS.

Equipment gas pressure (the pressure downstream of the pressure regulator) may be tested by adapting a water column gauge to the plugged ports on the main gas manifold. The pressure regulator supplied with the Gas Griddle is factory set for a nominal gas pressure of 5” w.c.

Be sure to remove any adapters, and to re-plugand leak check the port before returning the griddle to service. Leak testing should be performed using a water/soap solution. DO NOT USE FLAME TO CHECK FOR GAS LEAKS.

GAS SUPPLY FLOW VOLUME TESTING REQUIREMENTS

While testing for adequate gas pressure, be sure all other gas appliances that utilize the same source piping are in operation with burners ON in order to ensure accurate operational conditions.

If flow volume in the system piping is marginal, and should other appliances on that system not be consuming gas while testing for pressure, the test results may be inaccurate.

121 p/n 45324 OpManualBuilt-InElectric Griddles

IMPORTANT:

PRESSURE TESTING MUST BE PERFORMED BY A QUALIFIED TECHNICIAN ONLY.

NOTE: The maximum inlet pressure from the supply piping must not exceed ½ p.s.i (14” W.C.) Pressure above this limit will damage the regulator and gas valves.

Port for measuring outlet gas pressure is located on the manifold. Remove the grease drawer to gain access. Remove the allen head plug sealing the test port, then connect the hose of a water column gauge.

Be sure to reinstall the allen head plug at the conclusion of testing.

PURGING AIR FROM GAS LINES

Air must be purged from the gas lines for the initial startup.

Turn the knob on the safety valve to PILOT, press and hold until a flame can be established at the pilot burner. Repeat for each pilot.

Caution must be taken to ensure that no raw gas is present in the surrounding area when attempting to place the Griddle into operation.

SET GAS PRESSURE:

Turn the gas shut-offvalveOFF.

Remove the plug in the gas pressure measurement tap and attach a manometer. Turn the shut-offvalveON. Light the pilot light and turn both gas control valves toHI.

Remove the cap from the pressure regulator. Turn the adjusting screw clockwise to increase pressure; counter-clockwiseto decrease pressure. Adjust the gas pressure regulator for:

5” water column (natural gas); or, 10” water column (propane).

When finished, replace cap on regulator, turn shut-offvalveOFF, remove manometer and reinstall plug in tap. Turnshut-offvalve backON and relight the pilot light.

PILOT FLAME ADJUSTMENT

The pilot flame may be adjusted at the safety valve by removing the pilot adjusting screw cover (notice the fiber washer) and turning the adjusting screw until the pilot flame covers 3/8” to1/2” tall section of the thermocouple. This will ensure that the thermocouple will energize the pilot valve and maintain the pilot flame. Remember to replace the cover and fiber washer after adjustments are completed.

To check the calibration of the thermopile, turn the main burner control knob to OFF. Connect a millivolt meter to the TP andTP TH connections on the red terminal block on the safety valve. The thermocouple should generate 200mV (minimum) within 2 minutes of the pilot flame being lit. 250 mV will provide sufficient power to open both the pilot valve and main burner valve.

To conserve thermocouple life and reduce gas consumption, the reading should be no more than 500 mV.

MAIN BURNER AIR/FUEL MIXTURE

Each main burner has an adjustment shutter at the inlet end of the burner. This collar is locked by a 1/4” hex head screw. Loosen the screw and rotate the shutter to adjust the amount of combustion air mixed with the incoming gas as it enters the main burner. Adjust the fuel/air mixture to produce a steady, blue flame.Re-tightenthe lock screw after the proper mixture has been set.
