GAS CONNECTIONS
Gas supply connections and any pipe joint compound must be resistant to
the
action of propane gases.
Location of the gas inlet is at the top right rear corner of the top panel. Codes require that
a gas shutoff valve must be installed in the gas line ahead of the Cheesemelter.
Use a ¾” NPT gas supply line for the cheesemelter inlet. All flexible and semi-rigid gas
supply lines must comply with the applicable ANSI standard. To ensure maximum
operating efficiency this appliance must be connected with a gas supply line of solid pipe
or a commercial type Flexible Connector with the net inside diameter (I.D.) as large as or
larger than the gas pipe inlet on this appliance.
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
After checking for leaks all lines receiving gas should be fully purged to remove air.
Maximum line pressure for natural and propane gas is 14" W.C. Minimum line pressure is
7" W.C. for natural gas and 11" W.C. for propane gas.
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
