SERVICE PROCEDURES AND ADJUSTMENTS

GAS SUPPLY CHECKS

If the gas supply piping is to be tested at a test pressure in excess of 1/2 psi (3.45 kPa), the appliance and its individual shutoff valve must be disconnected from the supply line. If the gas supply piping is to be tested at a pressure equal to or less than 1/2 psi (3.45 kPa), the individual shutoff valve must be closed during testing.

REGULATOR ADJUSTMENT

(ALL MODELS)

WARNING: SHUT OFF THE GAS BEFORE SERVICING.

Accurate gas pressure adjustment can only be made with the gas on and the burner lit. In addition the supply line pressure to the broiler must be at least 1.0” W.C. greater than what is stated on the broiler unit rating plate.

Regulators are preadjusted for natural or propane gas as specified on the broiler rating plate.

1.Connect the manometer to the main gas manifold pipe of the broiler. Turn on gas.

2.Light one burner and take a reading.

3.Light all burners and take a reading.

4.Light all the gas appliances on the same supply line and take a reading.

A.At no time should the pressure drop more than 1/2” W.C. A large pressure drop could be an indication that the gas supply line is too small or a blockage. Check supply line pressure to ensure that it is at least 1.0” greater than the specified operating pressure of the broiler. Check with the gas provider for the proper size gas line.
