Is there a problem?
It may occur that the cooktop does not function or does not
function properly. Before calling customer service for
assistance, lets see what can be done.
First of all, check to see that there are no interruptions in
the gas and electrical supplies, and, in particular, that the
gas valves for the mains are open.
The burner does not light or the flame is not uniform
around the burner.
Check to make sure that:
The gas holes on the burner are not clogged;
All of the movable parts that make up the burner are
mounted correctly;
There are no draughts around the cooking surface.
The burner does not remain on when set to "Low".
Check to make sure that:
The gas holes are not clogged.
There are no draughts near the cooking surface.
The minimum has been adjusted correctly (see the
section entitled, "Minimum Regulation").
The cookware is not stable.
Check to make sure that:
The bottom of the cookware is perfectly flat.
The cookware is centered correctly on the burner or
electric hot plate.
The support grids have not been inverted.
If, despite all of these checks, the cooktop does not function
properly and problem persists, call the nearest Merloni Elet-
trodomestici Customer Service Centre, informing them of:
- The type of problem.
- The abbreviation used to identify the model (Mod. ...) as
indicated on the warranty.
Never call upon technicians not authorized by the
manufacturer, and refuse to accept spare parts that are not
original.
Before cleaning or performing maintenance on your
appliance, disconnect it from the electrical power supply.
To extend the life of the cooktop, it is absolutely
indispensable that it be cleaned carefully and thoroughly
on a frequent basis, keeping in mind the following:
The enameled parts and the glass top, if present, must
be washed with warm water without using abrasive
powders or corrosive substances which could ruin them;
The removable parts of the burners should be washed
frequently with warm water and soap, making sure to
remove caked-on substance. Check that the gas outlet
slits are not clogged. Dry the burners carefully before
using them again.
Frequently clean the end part of the automatic glow plugs
of the hob.
The steel parts and especially the areas with the screen-
printed symbols should not be cleaned with diluents or
abrasive detergents. It is advisable to use only a a damp
cloth with tepid water and a liquid detergent;
Avoid cleaning appliance parts when they are still warm;
Avoid leaving acidy liquids (vinegar, lemon juice, aggres-
sive detergents, etc.) on enamelled or painted parts;
Greasing the Gas Valves
Over time, the gas valves may stick or become difficult to
turn. If this is the case, they must be cleaned on the inside
and then regreased.
Important: This procedure must be performed by a
technician authorized by the manufacturer.
How to Keep Your Cooktop in Shape
To turn off the burner, turn the knob clockwise to the off
position “ “ .
• Difficulty in ignition is sometimes due to air inside the gas
duct.
• When the equipment is not in operation, check that the
knobs are in the off position “ “ . The main gas supply cut-
off cock should also be closed.
Practical tips for using the burners
To obtain maximum efficiency from the burners, it is advisable
to use only  pans with a diameter that is suitable for the
burner being used, so that the flame does not extend beyond
the pan base (see following table).
When a liquid starts boiling, it is advisable to turn the flame
down just enough to keep the liquid simmering.

The hob is fitted with pan reducing
support 
(fig.1), which should only be
used on the auxiliary "A" burner (small).
