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.
