must be at least 30 cm height difference between the drain pipe of the appliance and the drain
point in order to assure regular water drainage.
Furthermore, the minimum "air gap" must be 25 mm (distance between the drain pipe from
the appliance and the cup of the drain duct pipe).
In any case, for reasons of compliance with health regulations in force, the piping connected to
the drain pipe of the appliance must not be in direct contact with the drain point.
It is recommended to connect the appliance's drain to the grey water network through an
adequate syphon, in order to stop steam from coming out of the drain.
The connection to drain water must be done separately for each appliance; in case of several
appliances connected to the same drain pipe, ensure the pipe is suitably sized to assure regular
drainage with no hindrances.

2.11 Thermal breaker safety devices

The appliance is equipped with a manually reset safety thermostat, to protect against excessive
and hazardous overheating which might accidentally occur inside it. In the event of tripping the
device interrupts power supply to the appliance and the incoming gas to the burner.
3. START-UP (for installation technician)
3.1 Check of nominal thermal capacity
The nominal thermal capacity must be verified by an authorised technician or by the gas supply
Body, observing the information in this use manual. This check must be performed for new
installations, adaptation to another type of gas and during all extraordinary maintenance jobs.
There is no other possibility of adjusting the nominal thermal capacity – this is done by
measuring correct connection pressure and checking if the injector being used is of appropriate
diameter. The nominal thermal capacity is controlled by using a gas meter and a chronometer.
The exact volume of gas that must flow through per time unit can be obtained from the
technical specifications table. This value must be maintained in the specified range, the
permissible tolerance being 5%.
3.2 Check of connection pressure (Fig. 6)
The connection pressure is measured, with the unit working, using a pressure gauge for liquids
(for instance a liquid-level gauge with a minimum resolution of 0,1 mbar). To carry out this test,
remove the back of the unit and connect the "T" hose of the "M" gauge to the "P" inlet
pressure tapping point of the gas solenoid valve, after unscrewing the tapping point screw.
