Gas Connections - Vulcan GHCB40C Manuel D'installation Et D'utilisation

GAS CONNECTIONS

CAUTION: All gas supply connections and any pipe joint compound used must be
resistant to the action of propane gases.
Connect gas supply to the broiler(s). Make sure the pipes are clean and free of obstructions, dirt and
piping compound.
Codes require that a gas shutoff valve be installed in the gas line ahead of the broiler.
Natural gas broilers and propane gas broilers are equipped with fixed orifices and no adjustment is
necessary.
Model IR Broilers for operation on natural or propane gas are also equipped with a factory-preset
pressure regulator, with an outlet pressure of 6" (1.49 mb) Water Column for natural gas supply and
10" (2.49 mb) Water Column for propane gas supply. No further adjustment should be required.
Models GHCB40 and GHCB44 also require a pressure regulator (not supplied). The regulators must
have:
• C.S.A. design certification.
• Enough regulation capacity for the total connected gas load.
• Pressure adjustment range to allow adjustment for the manifold pressure marked on the rating
plate.
Unless the manifold pressure on all connected broilers is the same, a separate regulator must be
supplied for each broiler having different manifold pressures.
If the front plates do not line up perfectly, adjust by using bolts under the front plate.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR
LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
Ensure that burner heads are connected.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When test pressures exceed
disconnected from the gas supply piping system.
When test pressures are
system by closing its individual manual shutoff valve.
FLUE CONNECTIONS
DO NOT obstruct the flow of flue gases from the flue duct located on the rear of the broiler. It is
recommended that the flue gases be ventilated to the outside of the building through a ventilation
system installed by qualified personnel.
From the termination of the broiler flue vent to the filters of the hood venting system, an 18" (457 mm)
minimum clearance must be maintained.
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.
