GAS CONNECTIONS
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
appliance. The gas supply line must be at least the equivalent of ¾” iron pipe.
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 appliance 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 appliance 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 hotplate 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 hotplate 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 hotplate (Fig. 1) and the regulator is positioned with the vent plug and the conversion
plug cover upright(Fig. 2).
