Gas Supply Requirements - KitchenAid 740-0004 Installation Instructions And Use & Care Manual

Gas Supply Requirements

Observe all governing codes and ordinances.
IMPORTANT: This installation must conform with all local
codes and ordinances. In the absence of local codes,
installation must conform with American National Standard,
National Fuel Gas Code ANSI Z223.1 - latest edition or
CAN/CGA B149.1 – latest edition.
IMPORTANT: Grill must be connected to a regulated gas
supply. Refer to the model/serial rating plate for information on
the type of gas that can be used. If this information does not
agree with the type of gas available, check with your local gas
supplier.
Gas Conversion:
No attempt shall be made to convert the grill from the gas
specified on the model/serial rating plate for use with a different
gas type without consulting the serving gas supplier. The
conversion kit supplied with the grill must be used. See "Gas
Conversions" section for instructions.
Gas Pressure Regulator
The gas pressure regulator supplied with this grill must be used.
The inlet (supply) pressure to the regulator should be as follows
for proper operation:
LP Gas:
Operating pressure: 2.74 kPa (11" WCP)
Inlet (supply) pressure: 2.74 to 3.48 kPa (11" to 14" WCP)
Natural Gas:
Operating pressure: 1.00 kPa (4" WCP)
Inlet (supply) pressure: 1.74 to 3.48 kPa (7" to 14" WCP)
maximum.
Contact local gas supplier if you are not sure about the inlet
(supply) pressure.
Burner Requirements for High Altitude
Input ratings shown on the model/serial rating plate are for
elevations up to 609.6 m (2,000 ft.).
For elevations above 609.6 m (2,000 ft.), ratings are reduced at
a rate of 4% for each 304.8 m (1,000 ft.) above sea level.
Orifice conversion is required. See "Assistance" section to
order.
Gas Supply Line Pressure Testing
Testing above 3.5 kPa (1/2 psig) or 14" WCP (gauge):
The grill and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing
of that system at test pressures greater than 3.5 kPa (1/2 psig).
Testing below 3.5 kPa (1/2 psig) or 14" WCP (gauge) or
lower:
The grill must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than 3.5 kPa (1/2 psig).
