INSTALLATION
To be carried out by qualifi ed 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.
The gas fume evacuation must be effected with a pipe of a diameter not less than that required by the boiler
and it must be connected to a fl ue 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 protrude inside the fl ue 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 fl exible stainless steel pipe with
continuous wall of the approved type. The fl exible 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 G20 (Natural Gas) and G30/G31 (LPG), category II 2H3+, with rated pressures of 20
mbar, 28/30 mbar and 37 mbar respectively.
PUTTING THE BOILER INTO SERVICE
●
Proceed with the clearing out of air.
●
Check that there are no gas leaks (use a soapy solution or equivalent product).
SYSTEM FILLING
Open the feeding tap slowly until the system reaches a working pressure (indicated on the hydrometer) of 1.5
bar, then close it. Check that the automatic air bleed valve, on the circulator, has its cap loosened; run the
circulator repeatedly to eliminate any air in the circuit.
IGNITION
Open the gas tap and turn the selector switch to the desired position. The burner will ignite automatically.
Should the unit fail to ignite see if the lock-out indicator is on. If it is, turn the selector switch to RESET so that
the boiler repeats the ignition sequence. Then adjust heating and hot water temperature as desired via the
appropriate controls.
