NATURAL GAS INSTALLATION
The installation must conform with local codes or, in the absence of local codes, with either the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, Natural Gas and Propane Installation Code, CSA
B149.1 or Propane Storage and Handling Code, B149.2.
1. This gas appliance and its individual shuto valve must be disconnected from the gas supply
piping system during any pressure testing of that system at the test pressures in excess of 1/2
psi (3.5 kPa).
2. This appliance must be isolated from the gas supply piping system by closing its individual
manual shuto valve during any pressure testing of the gas supply piping system at test pres-
sures equal to or less than 1/2 psi (3.5 kPa).
If the Teppanyaki Griddle is factory built for Natural Gas, the regulator supplied is set for 4” wa-
ter column. The regulator is convertible to 10 in wc (2.49 kPa) for plumb-in system LP application. Do
not use with a 20-lb LP cylinder. Make sure that the regulator is set for the correct gas type. To check,
remove the brass hex cap. You will nd the conversion plastic pin attached to the cap to the under-
side of the cap. If the disc (1/2 in. diameter) of the pin is close to the cap, then the regulator is set for
Natural Gas. If the disc is at the tip of the pin, away from the brass cap, the regulator is set for system
LP application. To convert to Natural Gas, remove the plastic conversion pin and invert and replace it
back in a manner such that the disc is close to the brass cap. For both Natural and LP, the maximum
inlet pressure is 14 in wc (3.5 kPa).
A typical Natural Gas installation is shown below. Make sure that the factory-supplied regulator
is used and installed with the arrow mark on the regulator pointing towards the appliance. Do not use
any replacement regulator other than that specied by DELTA HEAT. Use only pipe sealants that are
approved for use with Natural and LP gases. An installer-supplied gas shuto valve must be installed
in an accessible location.
