HOB BURNERS
Each hob burner is controlled by a separate gas tap
operated by a control knob (fig. 4.1) which has 3
positions marked on the control panel, these are:
– Symbol
0
: tap closed (burner off)
– Symbol
: High (maximum)
– Symbol
: Low (minimum)
Push in and turn the knob anti-clockwise to the
selected position.
The maximum aperture position permits rapid boiling of liquids, whereas the minimum
aperture position allows slower 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 small flame symbol.
Other intermediate operating adjustments can be achieved by positioning the indicator
between the maximum and minimum aperture positions, not between the maximum
aperture and closed positions.
N.B. When the hob is not being used, set the gas knobs to their closed positions and
also close the cock valve on the gas bottle or the main gas supply line.
How to use the Hob Burners

LIGHTING THE BURNERS
To ignite the burner, the following instructions are to be followed:
1) Press in the corresponding knob and turn counter-clockwise to the full flame position
marked by the
symbol (fig. 4.1) and hold the knob in until the flame has been lit.
In the case of a mains failure light the burner with a match or lighted taper.
2) Wait about ten seconds after the gas lighting before releasing the knob (starting time
for the valve).
3) Adjust the gas valve to the desired power.
Important
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 closed
0
position,
wait for at least 1 minute
and then repeat the lighting procedure.
If your local gas supply makes it difficult to light the burner with the knob set to maxi-
mum, set the knob to minimum and repeat the operation.
