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.
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. Minor adjustments may be required based on site specific gas pressure.
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 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 cheesemelter be connected
to supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.
Gas supply connections and any pipe joint compound must be
resistant to the action of propane gases.
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
