Safety Information

Gas Supply Pressure

To avoid property damage, maximum gas supply
pressure must not exceed ½ psi (3.5kPa)(14" WCP).
Appliance and individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of ½ psig (3.5kPa)(14" WCP).
• Appliance must be isolated from gas supply piping
system by closing manual shutoff valve during any
pressure testing of the gas supply piping system at
test pressures equal to or less than ½ psig (3.5kPa)
(14" WCP).
• Gas supply pressure for checking regulator setting
must be at least 1" WCP above manifold pressure
shown on rating label.
• Must use pressure regulator supplied with cooktop.

Pressure Regulator Connection

The pressure regulator connects directly to the 90
degree fitting that exits the upper right hand corner of
cooktop.
• Support regulator when installing gas supply.
• Do not overtighten regulator when attaching to gas
manifold pipe. Overtightening may crack regulator.
• Do not overtighten fitting or hard pipe when
attaching to gas regulator. Overtightening may crack
regulator.

Gas Supply Location

Locate gas supply so manual shutoff valve is accessible
after installation. Gas supply can be installed in adjacent
cabinet or behind access panel. Avoid interference with
electrical connection.

Gas Connection

To avoid property damage or personal injury, only
use a new flexible connector that is AGA/CGA
design certifiied.
• Do not use an old connector.
• Do not reuse a connector after moving
appliance.
Connect gas supply to regulator using hard pipe or a
flexible connector. Pressure regulator supplied with this
appliance has a 1/2 inch NPT female connection.
• A manual shutoff, not supplied with cooktop, must
be installed in an accessible location outside of
cooktop.
• Use joint compound that is resistant to action of
propane gas on all male pipe threads.
• Use supplied pressure regulator only.
• Do not over tighten gas fitting when attaching to
pressure regulator. Over tightening may crack
regulator.
• Support pressure regulator with wrench when
installing gas fitting.
