STEP 6
PREPARE FOR DUCTWORK
NOTE: Ductwork MUST be vented outside.
DO NOT vent into a wall, ceiling, crawlspace,
attic or any concealed space.
Determine the best route for ductwork; it can
be routed in a variety of ways depending on the
kitchen layout.

STEP 7
GAS CONNECTION
Make the gas connection
to the inlet of the
pressure regulator on this
appliance with a 1/2" pipe
nipple with male pipe
thread. Use an approved
pipe joint compound
resistant to the action
of LP gas at pipe
connections.
Install a manual shut-off
valve in the gas line in an
easily accessible location,
as close to the pipe stub
as possible, making
allowances for the
ventilation ducting.
Be sure you know how
and where to shut off the
gas supply to the cooktop.
NOTE:
Instead of using solid piping to connect to
pressure regulator, an approved flexible metal
appliance connector may be used between the
pipe stub and shut off valve and the pressure
regulator, if local codes permit.
Transition
Appropriate flare union adapters are required at
elbow
each end of the flexible connector.
Turn on the gas; check for leaks using a liquid
leak detector at all joints in the system.
CAUTION: DO NOT USE A FLAME
TO CHECK FOR GAS LEAKS.
