1.3

EVACUATION OF EXHAUST FUMES

The appliances must be placed in premises from which exhaust fumes can be evacuated in compliance with
installation standards. Our appliances are classifi ed type A and cannot be connected to an exhaust fume pipe.
The exhaust fumes must be evacuated via extraction hoods or similar devices that are connected to an effi cient
fl ue or else they must be evacuated directly to the outside at a rate that does not fall below the specifi ed minimum
rate.
In all cases, if the exhaust fumes are removed through forced evacuation, aspiration must be interrupted if the
aspiration value falls below the specifi ed limit. The gas supply must be stored to the burners manually.

CONNECTING GAS

Installation operations, adaptations to other types of gas, commissioning and the elimination of system faults must
be carried out only by qualifi ed personnel in accordance with current rules and standards. The gas systems, wiring
and premises in which the appliances are installed must comply with current rules and standards. In particular,
the air supply for burner combustion must be 2m
Accident prevention, fi re prevention and anti-panic measures in businesses open to the public must be complied
with.
The appliance has a rating plate (Fig.1) and the installation instructions are given in the main European languages.
The packing also displays an additional rating plate showing the values for which the appliance is rated and the
country of destination.
Check on the rating plate inside the door or on the left-hand side that the appliance has been tested and approved
for the type of gas that the user uses.
Check that the nozzles on the appliance are suitable for the available gas supply.
Check on the rating plate that the pressure reducer is adequate to the appliance's gas supply (Fig. 1).
The appliance has been set in the company to use a 20-mbar G20.
Do not reduce the diameter of the section between the reducer and the appliance. Fit a gas fi lter above the pres-
sure adjuster in order to ensure optimum operation.
During initial installation and during maintenance or adaptation to another type of gas nominal heat input must be
measured. It can be measured by using the volumetric method with the aid of a litre counter or a chronometer.
After checking connecting pressure and the diameter of the injectors (which must be stamped on the injector),
measure the hourly thermal fl ow of the gas and compare the results with the value given on Table of the Technical
Specifi cation under the heading 'Gas consumption'. Deviation of ± 5% from nominal value is permitted.
