CHECKING PRIMARY AIR TO THE MAIN BURNERS
All the burners are tted with an air regulator by means of which the primary air can be varied thanks to an adjustable
bush that can be locked with a screw. In the “Burner Technical Data” table you will nd the approximate values for the
“h” parameter (primary air). The ow of primary air must be regulated so there is no detachment of the ame when the
burner is cold or a return of the ame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adjusting bush until the ame
stops sputtering and becomes an intense blue colour.

CLEANING AND MAINTENANCE
Attention! During cleaning, do not wash the external parts of the appliance with direct sprays of water or with high
pressure.
After every use, clean the appliance thoroughly. Daily cleaning after switching off the appliance ensures the perfect
functioning and long life of the appliance.
Before starting to clean the appliance, disconnect the power supply. The parts in steel must be washed with hot
water and neutral detergent, then rinsed thoroughly in order to eliminate all traces of detergent; after which, dried
with a dry cloth.
Do not use abrasive or corrosive detergents.
The enamelled parts should be washed with soapy water.
After cleaning, turn the elements back correctly.
Important: As well as ordinary cleaning and maintenance, it is advisable to have the installation checked by an
installer at least once a year.
It is therefore suggested to draw up an after-sales assistance contract.
Cleaning burnished brass surfaces
No synthetic protective varnishes have been used to obtain the special burnishing effect on the burnished brass
details in order to avoid spoiling the beauty of the brass with an articial patina. The antique nish of the surface
is the result of natural oxidation that has simply been accelerated. All the natural antique nish brass surfaces can
be cleaned with any kitchen degreasing detergent, accompanied by the use of an abrasive scouring pad (the
green colored type used for washing dishes). It is recommended that the metal be rubbed, uniformly applying light
pressure, until the desired effect is achieved.
The brass details should then be dried.
Do not use polish as this is suitable for maintaining the gloss but not the antique nish and could result in an effect
that is not compliant with our products. Any spots that may appear over time on the burnished brass surfaces should
be considered as a desirable and particular characteristic of our craft metal working processes.
Cleaning chromium-plated brass surfaces
No synthetic varnishes have been used to obtain the special polish on the chromium-plated brass details in order to
avoid spoiling the beauty of the chromium plating with an articial patina. All the chromium-plated surfaces should
be cleaned, where necessary, with a soft, possibly micro-ber cloth, combined with metal polishing products, if
required. Do not use abrasive pads.
Cleaning satin nish nickel-plated brass surfaces
No synthetic varnishes have been used to obtain the special nickel-plating on the satin nish nickel-plated brass
details in order to avoid spoiling the beauty of the nickel-plated, satin nished solid brass with an articial patina. All
the nickel-plated and satin nished brass surfaces should be cleaned, where necessary, with a soft, possibly micro-
ber cloth, combined with a neutral detergent, if required. Do not use abrasive pads.
Cleaning the varnished surfaces
All the varnished surfaces should be cleaned using a neutral detergent and, where necessary, a soft, possibly micro-
ber cloth. Do not use abrasive pads or any other chemical products.
Cleaning brushed steel surfaces
All the brushed steel surfaces should be cleaned using degreasing products or products specically designed to be
used on steel and, where necessary, extra-ne steel wool or extra-thin sandpaper.
