INSTALLATION
To be carried out by qualified personnel.
The installation must be in compliance with the stipulations of the law regarding the evacuation of combustion
materials according to the REGULATIONS IN FORCE.
It is compulsory that the gas fumes evacuation is effected with a pipe of a diameter not less than that required
by the boiler and that it comes connected to a flue pipe suitable for the capacity of the installation.
For connection of appliances to smoke conduits:
a) they must be easy to dismantle;
b) they must be sealed and of a material able to resist the products of combustion and their possible
condensation;
c)
they must not have regulation devices (gate valves). If such devices are already in operation they must be
eliminated;
d) the connection itself must not project onto the inside of the flue pipe but stop before the internal face of the
same.
GAS CONNECTION
Carry out the gas connection in accordance with the regulations in force.
The boiler must be connected to the installation with a rigid metal pipe or a flexible stainless steel pipe with
continuous wall of the type approved. The flexible corrugated metal pipes must be installed in such a way that
their length, in a state of maximum extension, is not greater than 2000 mm. The boilers are calibrated and
tested to function with NATURAL GAS and LIQUID GAS, category II 2H3+, with rated pressure correspondant
respectively to 20 mbars, 28/30 mbars and 37 mbars.
SETTING THE INSTALLATION IN SERVICE
G Proceed with the clearing out of air.
G Check that there are not any gas leaks (use a soapy
solution or equivalent product).
STARTING UP
REFILLING INSTALLATION
Open the inlet cock (1) slowly until the system pressure indicated on the
hydrometer (2) reaches 1.5 bar, then close it. Check that the 3-way valve
(3) is in the manual position and that the automatic air purge valve (4) on
the circulator has its cap loosened and is functioning properly. Then vent
any air by means of the manual valve (5) on the boiler. Before ignition
make sure that water pressure has not dropped beneath the initial head
value.
For optimum boiler performance make sure that system pressure never
drops below 1.5 bar.
SWITCHING ON
Open the gas cock. Turn the main wall-mounted electrical power switch to
ON. Select the desired mode on the control unit (summer/winter/off),
using the indicator lights as a guide.
