INSTALLATION INSTRUCTIONS
1. PROVIDE ADEQUATE GAS SUPPLY
This cooktop is designed to operate at a pressure
of 5” of water column on natural gas or 10” of water
column on LP, propan or butane gas.
Make sure you are supplying your cooktop with the
type of gas for which it is designed.
This cooktop is convertible for use on natural or
propane gas. When using this cooktop on
LP gas,
conversion must be made by a qualified LP
installer
before attempting to operate the cooktop on that
gas.
For correct operation, the pressure of natural gas
supplied to the regulator should between 5” and
13” of water column.
For LP gas, the pressure supplied must be between
10” and 13” of water column.
When checking for correct operation of the regulator,
the inlet pressure must be at least 1” more than the
operating -manifold- pressure as given above.
The pressure regulator located at the inlet of the
cooktop manifold must remain in the supply line
regardless of whether natural or LP gas is being used.
A flexible metal appliance connector used to connect
the cooktop to the gas supply line must have an
I.D.
of 5/8” and can be 3 feet in length easily for
installation.
In Canada, flexible connectors should
be single wall metal connectors less than 6 feet
in length.
2. CONNECT THE COOKTOP TO GAS
Shut off the main gas supply valve before
removing the old cooktop and leave it off until the
new hook-up has been completed. Don’t forget to
relight the pilot on other gas appliances when you
turn the gas back on.
Because hard piping restricts movement of the
cooktop, the use of a CSA International-certified
flexible metal appliance connector is recommended
unless local codes require a hard-piped connection.
Never reuse an old connector when installing a new
cooktop. If the hard piping method is used, you must
carefully align the pipe; the cooktop cannot be moved
after the connection is made.
To protect gas leaks, put pipe joint compound on,
all male -external- pipe threads.
Install a manual gas line shut-off valve in the gas
line in an easily accessed location outside of the
cooktop. Be sure everyone operating the
cooktop knows where and how to shut off the
gas supply to the cooktop.
Install male 1/2” flare union adapter to the 1/2”
NPT internal thread at inlet of pressure regulator.
Use a backup wrench on the pressure regulator
fitting to
prevent damage.
Install male 1/2” or 3/4” flare union adapter to the
NPT internal thread of the manual shut-off valve,
taking care to back-up the shut-off valve to keep
it from turning.
Connect flexible metal connector to the
adapter
on the cooktop. Position cooktop to permit
connection at the shut-off valve.
When all connections have been made, be
sure all cooktop controls are in the off position
and turn on the main gas supply valve.
Check gas leaks by using manometer.
If a manometer is not available, turn the gas supply
on to the cooktop and use a liquid leak detector
at all joints and connections to check for leak.
Tighten all connections if necessary to prevent
gas leakage in the cooktop or supply line.
WARNING!
DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.
Disconnect the cooktop and its individual shut-off
valve from the gas supply piping system during any
pressure testing of that system at test pressures
more than 1/2 psig(3.5kPa).
Isolate the cooktop from the gas supply piping system
by closing its individual shut-off valve during any
pressure testing of the gas supply system at test
pressures equal to or less than 1/2 psig(3.5kPa)
