Gas
The installation of the gas supply must be done by a qualified plumber in accordance with local gas codes; or in the
absence of local codes in accordance with the National Fuel Gas Code; ANSI Z223.1/NFPA 54, or the Natural Gas
and Propane Installation Code; CSA B149.1, as applicable including:
•
During a pressure test of the gas supply piping system, the appliance must be completely isolated by
disconnecting the quick disconnect gas line if the test pressure is above 0.5 psi [3.5 kPa]. If the test
pressure is equal to or below 0.5 psi [3.5 kPa], only the appliances manual shutoff valve must be closed.
THE ROTISSERIE IS VERY HOT WHEN OPERATING. MAKE SURE THAT THE MAIN GAS VALVE IS
INSTALLED IN A LOCATION EASILY ACCESSIBLE TO THE EMPLOYEES.
ENSURE THE FACILITY GAS SUPPLY IS TURNED OFF BEFORE OPENING ANY CONNECTIONS PRIOR TO
OR DURING THE GAS HOSE INSTALLATION AND CONNECTION OF THE ROTISSERIE.
A RESTRAINING DEVICE MUST BE INSTALLED SUCH THAT THE ROTISSERIE MOVEMENT IS LIMITED
WITHOUT RELYING ON THE 'QUICK-DISCONNECT' HARDWARE OR ITS ASSOCIATED PIPING.
It is required that Inferno 4500 rotisseries be equipped with quick-disconnect gas/water installation
hardware.
FOR A ROTISSERIE EQUIPPED WITH CASTERS, IT IS ALSO REQUIRED THAT IT BE EQUIPPED WITH A
CONNECTOR THAT COMPLIES WITH THE STANDARD FOR CONNECTORS FOR MOVABLE GAS
APPLIANCES, ANSI Z21.69 OR CONNECTORS FOR MOVABLE GAS APPLIANCES, CAN/CSA-6.16, AND A
QUICK DISCONNECT DEVICE THAT COMPLIES WITH THE STANDARD FOR QUICK DISCONNECT DEVICES
FOR USE WITH GAS FUEL, ANSI Z21.41 (CSA 6.9).
