using the gas cooktop
GAS BURNERS
Gas flow to the burners is adjusted by turning the knobs (illustrated in fig. 2.1) which
control the valves.
Turning the knob so that the indicator line points to the symbols printed on the panel
achieves the following functions:
OFF
= closed valve
HI
= maximum rate
LO
= minimum rate
The maximum aperture position permits rapid boiling of liquids, whereas the minimum
aperture position allows simmer warming of food or maintaining boiling conditions of
liquids.
To reduce the gas flow to minimum, rotate the knob further anti-clockwise to point the
indicator towards the LO position.
Other intermediate operating adjustments can be achieved by positioning the
indicator between the maximum and minimum aperture positions, and never between
the maximum aperture and OFF positions.
Fig. 2.1
N.B. When the cooktop is not being used, set the gas knobs to their OFF positions and also close the gas shut-off valve placed on the main gas supply line.
LIGHTING GAS BURNERS with safety valve device
In order to light the burner, you must:
1 – Turn the knob in an anti-clockwise direction up to the LITE-HI position (maximum
rate), push in, hold the knob until the flame has been lit (fig. 2.2).
The sparks produced by the lighter situated inside the relative burner will light the
flame.
In the event that the local gas supply conditions makes it difficult to light the burner in HI position, try again with the knob in LO position.
If there is no mains electrical supply, bring a lighted match close to the burner.
2 – Wait about ten seconds after the gas lights before releasing the knob (starting time
for the safety valve).
3 – Adjust the gas valve to the desired position.
Fig. 2.2
If the burner flame should go out for some reason, the safety valve will automatically
stop the gas flow.
To re-light the burner, return the knob to the OFF position, wait for at least 1 minute
and then repeat the lighting procedure.

CHOICE OF BURNER
(fig. 2.3)
The symbols printed on the panel beside the gas knobs indicate the correspondence
between the knob and the burner.
The most suitable burner is to be chosen according to the diameter and volume capacity of the container to be warmed.
It is important that the diameter of the pots or pans suitably match the heating potential of the burners in order not to jeopardise the efficiency of the burners, bringing about
a waste of gas fuel.
A small diameter pot or pan placed on a large burner does not necessarily mean that
boiling conditions are reached quicker.
Caution!
The cooktop becomes very hot during operation.
Keep children well out of reach.

b) Any conversion required must be performed by your dealer or a qualified licensed
plumber or gas service company. Please provide the service person with this
manual before work is started on the cooktop. (Gas conversions are the
responsibility of the dealer or end user.)
c) This cooktop can be used with NATURAL or LP/PROPANE gas. It is shipped from
the factory adjusted for use with NATURAL gas.
d) Manifold pressure should be checked with a manometer; NATURAL gas requires
4.0” W.C.P. and LP/PROPANE requires 11.0” W.C.P (see figure 5.4).
Incoming line pressure upstream from the regulator must be 1” W.C.P. higher than
the manifold pressure in order to check the regulator.
The regulator used on this cooktop can withstand a maximum input pressure of
1/2 PSI (14.0” W.C.P). If the line pressure is in excess of that amount, a stepdown regulator will be required.

4. 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 cooktop will be level and in line.
• Use joint compounds and gaskets that are resistant to action of natural or propane
gas on all male pipe threads.
• Do not over tighten gas fitting when attaching to pressure regulator. Over
tightening may crack regulator.
5. Leak Testing:
IMPORTANT: Leak testing of the appliance shall be conducted as follows:
• After final gas connection is made, turn on manual gas valve and test all
connections in gas supply piping and appliance for gas leaks with a soapy water
solution. During this test all appliance gas valves have to be closed.
• In order to avoid property damage or serious personal injury, never use a Iighted
match. If a leak is present, tighten joint or unscrew, apply more joint compound,
tighten again and retest connection for leak.

REGULATING THE BURNER MINIMUM SETTING
When switching from one type of gas to another, the minimum flow rate must also be
correct: the flame should not go out even when passing suddenly from maximum to
minimum flame.
The adjustment is performed with the burner lit, as follows:
– Turn the knob to the minimum position.
– Remove the tap knob.
– With a screwdriver turn the screw “A” to the correct setting.
