GAS Connection

All gas supply connections and any pipe joint compound must be resistant to the action of propane gases.

Purge the supply line to clean out any dust, dirt, or any foreign matter before connecting the line to the unit.

Codes require that a gas shut-off valve be installed in the gas line ahead of the charbroiler. The gas supply line must be at least the equivalent of ¾” iron pipe.

A pressure regulator is supplied and must be installed outside of the broiler when making the gas supply connection. Standard orifices are set for 4"WC (Water Column) for Natural Gas — 10"WC (Water Column) for Propane. Use the 1/8” pipe tap on the burner manifold for checking pressure. Make sure the gas piping is clean and free of obstructions, dirt, and piping compound.

An adequate gas supply is necessary. Undersized or low pressure lines will restrict the volume of gas required for satisfactory performance. A minimum supply pressure of 7" W.C. for natural gas and 11" W.C. for propane gas is recommended. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable drop.

When testing the gas supply piping system, if test pressures exceed ½ psig (3.45 kPa), the charbroiler and its individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are ½ psig (3.45 kPa) or less, the charbroiler must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the system.

Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water solution. Do not use an open flame.

GAS PRESSURE REGULATOR INSTALLATION

This charbroiler 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 charbroiler 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 charbroiler (Fig. 2) and the regulator is positioned with the vent plug and conversion plug cover upright (Fig. 3).
