PROVIDEADEQUATEGASSUPPLY
This cooktop is designed to operate on natural gas
at 4" of water column pressure or on LP gas at 10"
of water column pressure. It is shipped from the
factory set for natural gas. If you decide to use
this cooktop with LP gas, conversion adjustments
must be made by a service technician or other
qualified person.
A pressure regulator is to be connected in series
with the manifold of the cooktop and must
remain in series with the supply line regardless
of whether natural or LP gas is being used.
For proper operation, the maximum inlet
pressure to the regulator must be no more
than 10" water column pressure for natural
gas, or 14" water column pressure for LP
gas. For checking the regulator, the inlet
pressure must be at least 1" greater than the
regulator output setting. If the regulator is set
for 4" of water column pressure, the inlet
pressure must be at least 5". If the regulator is
set for 10", the inlet pressure must be at least 11".
For ease of installation, and if local codes permit,
the gas supply line into the cooktop should be
1/2" or 3/4" I.D. flexible metal appliance
connector three to five feet in length.

Cut hole in the cabinet wall or floor as
appropriate for your installation. Make sure
the exhaust duct is located between wall studs or
the floor joists.
Cut only one hole in the cabinet, depending on
the route of the ductwork.
The location of the hole is different for
left and right side venting.
