6.4 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 ½ Psi (3.5 kPa). If the test pressure is
equal to or below ½ 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 3500 ROTISSERIES BE EQUIPPED WITH QUICK-
DISCONNECT GAS/WATER INSTALLATION HARDWARE.
6.4.1 Gas pressure
Natural Gas Incoming Pressure:
7” W.C. (1.74 kPa) – 12” W.C. (2.99 kPa).
Propane Incoming Pressure:
11” W.C. (2.74 kPa) – 12” W.C. (2.99 kPa).
6.4.2 Quick disconnect flexible hose
All hardware required for a quick-disconnect gas/water installation may be purchased from HARDT. The quick-
disconnect flexible hose and pipe adapter (both shown in
) are available from Hardt.
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
