Gas Cooktop Installation 10
GAS SUPPLY LINE
IMPORTANT NOTE: The gas cooktop must be connected
to a regulated gas supply.
A gas supply line of 3 / 4 " (19) rigid pipe must be provided to
the cooktop. For LP gas, piping or tubing size can be 1 / 2 "
(13) minimum. LP gas suppliers usually determine the size
and materials used on the system. If local codes permit, a
certified, 1 / 2 " (13) or 3 / 4 " (19) ID flexible metal appliance
connector is recommended to connect the cooktop to the
gas supply line. The gas pressure regulator on the
cooktop has 1 / 2 " (13) female threads.
IMPORTANT NOTE: The supply line must be equipped
with an approved external gas shut-off valve located near
the cooktop in an accessible location. Do not block
access to the shut-off valve. Refer to the illustration below.
Wolf natural gas cooktops will function up to an altitude of
10,250' (3124 m) without any adjustment. LP gas cooktops
will function up to 8,600' (2621 m) without adjustment. If
the installation exceeds these elevations, contact your
authorized Wolf dealer for a high altitude conversion kit.
Gas Supply Requirements
IMPORTANT NOTE: This installation must conform with
local codes and ordinances. In the absence of local
codes, installations must conform with the American
National Standard, National Fuel Gas Code.
TYPES OF GAS
There are two types of gas, natural and liquid propane
(LP). Conversions are required in order for appliances
designed for one gas to be operated with the other gas.
Such conversions must be performed by Wolf factory
certified service. Make sure your gas cooktop is correctly
adjusted for the type of gas being used.
The product rating plate has information on the type of
gas that should be used. If this information does not agree
with the type of gas available, check with the local gas
supplier. The rating plate is located on the underside of
the cooktop. Refer to the illustration on page 3.

Before connecting the gas supply, make sure all valves
are in a closed position. Do not connect the gas supply
to an appliance that shows any sign of damage.
