VENTILATION HOOD
The broiler should be installed under a suitable ventilation hood. For safe operation and proper ventilation, keep the space between the broiler and vent hood free from any obstructions.
GAS CONNECTION
The data plate indicates the type od gas and pressure rate the unit is equipped to burn. DO NOT connect to any other gas type.
GAS PRESSURE REGULATOR
INSTALLATION
A pressure regulator is supplied and must be installed outside the broiler when making the gas supply connection. The regulator is preset at the factory for 6" W.C. (Water Column) for Natural Gas; 10" W.C. for Propane. No further adjustment should be required.
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. The recommended maximum supply pressure (upstream of the regulator) is 7" W.C. for natural gas and 11" W.C. for propane gas. With all units operating simultaneously, the manifold pressure on all units should not show any appreciable drop. At no time should the broiler be connected to supply pressure greater than 1/2 psig (3.45 kPa) or 14" W.C.
Figure 7
Install the regulator as close to the broiler 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 broiler (Fig. 7 and the regulator is positioned with the vent plug and adjustment screw upright (Fig. 8).
Figure 8
CAUTION: All gas supply connections and any pipe joint compound must be resistant to the action of propane.
Purge the supply line to clean out any dust, dirt, or foreign matter before connecting the line to the unit.
Codes require that a gas shutoff valve be installed in the gas line ahead of the broiler. The gas supply line must be at least the equivalent of 3/4" iron pipe.
When testing the gas supply piping system, if test pressures exceed 1/2 psig (3.45 kPa), the broiler and its individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are 1/2 psig (3.45 kPa) or less, the broiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the system.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
