Gas Conversions; Lp Gas Conversion - KitchenAid KGCU407 Installation Instructions Manual

IMPORTANT: Gas conversions from Natural gas to LP gas must
be done by a qualified installer.
WARNING
Explosion Hazard
Use a new CSA International approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to LP, have a qualified person make sure
gas pressure does not exceed 14" (36 cm) water
column.
Examples of a qualified person include:
licensed heating personnel,
authorized gas company personnel, and
authorized service personnel.
Failure to do so can result in death, explosion, or fire.

LP Gas Conversion

1. Turn the manual shutoff valve to the closed position.

C. Gas supply line
2. Unplug cooktop or disconnect power.
To Convert Gas Pressure Regulator
1. Remove the access cap by using a wrench, turning the
access cap counterclockwise.
2. Remove spring retainer from the cap by pushing against the
flat side of the spring retainer. Look at the spring retainer to
locate the "NAT" or "LP" position. Turn over the spring
retainer so the "LP" is showing on the bottom. Snap the
spring retainer back into the cap. Reinstall the cap onto the
regulator.

A. Access cap
B. Gasket
C. Gas pressure regulator
The regulator must be checked at a minimum 1" (2.5 cm)
water column above the set pressure. The inlet pressure to
the regulator should be as follows for operation and checking
the regulator setting:
LP Gas:
Minimum pressure 11" (27.9 cm) WCP
Maximum pressure 14" (35.5 cm) WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least
1" water column pressure above the manifold pressure
shown on the model/serial rating plate.
Line pressure testing above ½ psi gauge (14" WCP)
The cooktop and its individual shutoff valve must be
disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
½ psi (3.5 kPa).
Line pressure testing at ½ psi gauge (14" WCP) or lower
The cooktop 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 ½ psi (3.5 kPa).
