Gas connection specifications
Refer to the 'Safety and warnings' section for additional gas connection specifications.
Flexible hose connections
If local codes permit, CSA design-certified, flexible metal appliance connector is recommended
for connecting this cooktop to the gas supply line. Do not kink or damage the flexible connector
when moving the cooktop. The gas pressure regulator has 3/8" NPT female pipe threads. You will
need to determine the fittings required, depending on the size of your gas supply line, flexible
metal connector and shut-off valve.
Rigid pipe connections
If rigid pipe is used as a gas supply line, a combination of pipe fittings must be used to obtain an
in-line connection to the cooktop. All strains must be removed from the supply and fuel lines so
the cooktop will be level and free of pressure from the piping.
Use joint compounds and
washers resistant to the action
of all gas types on all male
pipe threads.
Do not overtighten the gas
fitting when attaching it to
the gas pressure regulator,
as doing so may crack the
regulator.
