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.

How to Keep Your Cooktop in Shape

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.

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.
