NOTE: See rating label for manifold pressure for the type of gas of your appliance.
The gas connection at the back of the rangetop (see below) features 1/2”NPT internal AND 3/4”NPT
external threads. Connect to gas supply using a minimum 3/4” inside diameter (1” OD) flexible
(semi–rigid) stainless steel gas hose with appropriate end fittings to prevent gas starvation. This
hose should be no more than 36” [91.4 cm] in length. Use the appropriate thread sealant on all
connections. Do not apply sealant to flare fittings. Use two wrenches when tightening the fittings.
The supply line must not interfere with the rear of the rangetop. Use caution when pushing the
rangetop against the back wall, so that you do not kink or crimp the flex hose as this could result in a
gas leak.
