GAS PRESSURE REGULATOR INSTALLATION

Gas regulator pressure is 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 cheesemelter 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 cheesemelter (Fig. 2) and the regulator is positioned with the vent plug and adjustment screw upright (Fig. 3).

The 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 cheesemelter be connected to supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.

TESTING THE GAS SUPPLY SYSTEM

When gas supply pressure exceeds ½ psig (3.45 kPa), the Cheesemelter and its individual shutoff valve must be disconnected from the gas supply piping system.

When gas supply pressure is ½ psig (3.45 kPa) or less, the Cheesemelter should be isolated from the gas supply system by closing its individual manual shutoff valve.

FLUE CONNECTIONS

DO NOT obstruct flow of flue gases from the flue located on the rear of the Cheesemelter. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel.

Information on the construction and installation of ventilating hoods may be obtained from the standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition), available from The National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
