GAS CONNECTION
Caution: The pipe thread compound used when installing pipes must be a type that is resistant
to the action of liquified petroleum or propane gases.
Codes require that a manual gas valve be installed in the gas supply line ahead of the appliance. Make
sure the pipes are clean and free of obstructions, dirt, and piping compound. A pressure regulator is
supplied loose with the Cheese Melter for installation in the gas supply line. The Natural gas regulator
requires a pressure of 5" Water Column. The Propane gas regulator requires a pressure of 10" Water
Column. The arrow on the rear of the pressure regulator indicates the direction of gas flow. The
regulator (Fig. 2) must be installed so the arrow points down. If it is installed so the arrow is not pointing

/
down, the pressure must be reset. Connect the Cheese Melter to the gas supply with a

for checking the gas pressure. Natural or Propane gas conversion and orifice changes for various
altitudes can be performed by Vulcan-authorized servicers.
WARNING: PRIOR TO START-UP, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
TESTING THE GAS SUPPLY PIPING
1
When test pressures exceed
/
psig (3.45 kPa) the Cheese Melter and its individual shut-off valve must
2
be disconnected from the gas supply piping system during any pressure testing of the system. When
1
test pressures are
/
psig (3.45 kPa) or less, the Cheese Melter must be isolated from the gas supply
2
piping system by closing its individual shut-off valve during any pressure testing of the system.
EXHAUST FAN
A mechanical exhaust hood must be installed above the appliance; the exhaust blower must have a
capacity of 200 CFM per square foot of broiler area, check local code for specific requirements.

LIGHTING THE GAS PILOT TUBE(S)
Before lighting the Cheese Melter, make sure that all burners are turned off. Wait 5 minutes. Turn on
the manual gas valve and use a taper to light the gas pilot tube(s). A gas pilot tube is located below
each burner (Fig. 3).
