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 gas pressure regulator preset at 5" Water Column
(W.C.) for natural gas and 10" W.C. for propane 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 adjustment screw upright (Fig. 3).
Fig. 2 Fig. 3
The minimum supply pressure (upstream of the regulator) should be 7-9" W.C. for natural
gas and 11-12" W.C. for propane gas. At no time should the charbroiler be connected to
supply pressure greater than ½ psig (3.45 kPa) or 14" W.C.
