4) The gas intake connection of the appliance has a “male thread.” When making the connection,
take care not to apply stresses of any kind to the appliance. Over-tightening may crack the
regulator resulting in a gas leak and possible fire or explosion (see Figure 14).
5) Once regulator is in place, open the shutoff valve in the gas supply line. Wait a few minutes for
gas to move through the gas line.
6) After connecting the cooktop to the gas supply, make sure all burners knobs are in the OFF
position and check the system for leaks with a manometer. If a manometer is not available, turn
on the gas supply and use a liquid leak detector (or soap and water) at all joints and connections
to check for leaks.
• Warning - Do not use a flame to check for leaks from gas connections. Checking for leaks with
a flame may result in a fire or explosion.
• Tighten all connections if necessary to prevent gas leakage in the cooktop or supply line.
• Check alignment of control knob valves after connecting the cooktop to the gas supply to be
sure the cooktop manifold pipe has not moved. A misalignment could cause the valve stems to rub
on the control panel, resulting in a gas leak at the valve.
• Disconnect this cooktop and its individual manual shutoff valve from the gas supply piping
system during any pressure testing of that system at test pressures greater than 1/2 psig (3.5 kPa or
14" water column).
