On no account should the stainless steel be cleaned with steel wool pads, brushes or scrapers in standard steel, in that
they could deposit ferrous particles which, by oxidising, cause rust spots. Stainless steel wool can be used in the direction
of the satin finish.
If the equipment is not be used for a long time, close the gas valve and wipe all the steel surfaces vigorously with a cloth
moistened with Vaseline oil in order to apply a protective layer; air the rooms periodically.
Before carrying out the connection, check on the technical data plate that the appliance has been tested and type-
approved for the type of gas available on the user’s premises.
Should the type of gas indicated on the plate not be that available, follow the instructions in the para
graph “Conversion to
different type of gas”.
The manufacturer of the appliance declines every responsability for possible mistake contained in this booklet imputable
to printing or transcription errors. It also reserves the right to bring changes to the product if retains useful or necessary
without jeopardizing the essential characteristics.
The manufacturing company declines any and every responsability if the rules brought in this manual are not strictly
observed.
The manufacturer of the appliance declines all responsibility for damage caused by faulty installation, tampering with the
appliance, improper use, poor maintenance, failure to observe local regulations and unskilled use.
THE DISCHARGE OF MACHINE MUST BE DONE IN COMPLIANCE WITH LAW. AT THE END OF HIS LIFE CYCLE
THIS APPLIANCE MUST BE DELIVERED TO COMPANY AUTHORIZED FOR THE DISCHARGE OF MACHINE AND
OF ITS COMPONENTS.
2. INSTALLATION
2.1 Installation of the appliance
The operations of installation, any conversion for use with other types of gas, start-up and the remedying of any faults in
the systems, must only be carried out by qualified staff, in accordance with current laws.
The gas systems and the rooms where the appliances are installed must fulfil the regulations existing in the various areas
and in particular consideration must be made of the fact that the air required for combustion of the burners is equal to 2
m
3
/h per kW of installed power and that accident prevention regulations must be observed.
2.2 Installation
Remove the appliances from the packing and position them in the place of use, levelling them and regulating their height
by means of the adjustable feet or other means.
Remove the protective film from the external panels, detaching it slowly to prevent the glue from remaining.
It is important that the walls adjacent to the appliance are protected against the heat. Place refractory sheets in between
them place the appliances at least 200 mm away from the side or rear walls.
2.3 Fumes extraction
The appliances must be installed in rooms suitable for the extraction of combustion products, in accordance with the
provisions of the installation instructions. Our equipment is considered (see specifications table) as:
“A1” TYPE GAS APPLIANCES
The A type appliances must be installed in sufficiently ventilated places in order to
prevent the concentrations of harmful substances in the room where the unit is
installed. They are not designed to be connected to a discharge line of
combustible materials. These appliances must discharge the combustible
products into the appropriate hoods, or similar devices, connected to a flue of
proven efficiency, or they may be connected directly to an outdoor vent.
Failing this, the use of an extractor fan is permitted, connected directly to an
external area, with sufficient capacity, which will then be increased by the
exchange of air necessary for the welfare of the workers under current
regulations, approximately 35 m³/h for each kW of gas power installed.
Forced fume evacuation under hood. In this case,
the end of the appliance’s
exhaust pipe must be at least 1.8 m above the floor on which the appliance stands
(the ground), and the mouth of the combustion fume pipe must be inside the same
extractor hood (Fig. 1
). The appliance’s gas supply must be connected to the
forced evacuation system so the former can be cut out in the event its capacity
falls below that required by the law in force. It should only be possible to restore
the appliance’s gas supply manually.
2.4 Connecting up gas
Check on the rating plate (Fig. 2), under the fires on the left-hand side, that the appliance has been tested and approved
for the type of gas that the uer uses.
Check that the nozzeles on the appliance are suitable for the available gas supply.
Check on the rating plate that
the pressure reducer is adeguate to the appliance’s gas supply
If gas supply pressure deviates by more than 10% from nominal pressure, fit a pressure regulator upstream of the
appliance to ensure that nominal pressure is maintained.
Do not reduce the diameter of the pipe between the reducer and the appliance.
Fit a gas filter upstream of the pressure regulator in order to optimise operating efficiency.
