GAS CONNECTION
(continued)
GAS CONNECTION
After connecting, the installation must be
checked for leaks. That procedure is on the
following page.
Connect to gas supply using a minimum 1/2”
inside diameter flexible (semi–rigid) stainless steel
gas hose to prevent gas starvation. This hose
should be no more than 36” [91.4 cm] in length,
or as permitted by applicable codes. The included
regulator must be installed between the shutoff
valve and the appliance, and must be mounted so
that its directional arrow (flow direction) points
toward the gas manifold.
NEVER REUSE OLD HOSES WHEN
INSTALLING THIS COOKTOP.
ANSI Z21.24/CSA 6.10 and ANSI Z21.75/CSA
6.27 codes require that a new gas appliance hose
must be used for a new appliance, when moving
an appliance to a new location, or as a result of
damage.
Use the appropriate thread sealant on all NPT
connections. Do not apply sealant to flare
fittings.
NEVER TIGHTEN TO MORE THAN 35 ft-lbs
[47.4 N-m] OF TORQUE.
Check alignment of valves after connecting the
cooktop to the gas supply to be sure the manifold
pipe has not been moved. A misalignment could
cause the valve knob stem to rub on the control
panel, resulting in a gas leak at the valve.
CAUTION
Do not attempt to attach the flexible hose directly
to an external pipe thread.
Connection requires proper adapters to join the flex hose and the pipe fittings.
FOR MASSACHUSETTS INSTALLATIONS:
1. Shut-off valve must be a “T” handle gas cock.
2. Flexible gas hose must not be longer than 36 inch [91.4 cm].
3. Not approved for installation in a bedroom or a bathroom unless unit is direct vent.
