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.
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 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 protrude inside 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 approved type. 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
pressures of 20 mbars, 28/30 mbars and 37 mbars 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).
START-UP
REFILLING INSTALLATION
Open the supply tap slowly until the pressure of the installation, indicated by the hydrometer, is raised
to the value of 1.5 bar, then close it again. Verify that the automatic air bleed valve on the circulator
has its cap loosened. Operate the circulator repeatedly to release any air remaining in the circuit.
SWITCHING ON
Open the gas tap and turn the selector switch to the desired position. The burner will ignite automatically.
Should the burner fail to ignite check the lock-out warning light to see whether it is on, and if so turn the
selector switch to the RESET position so that the boiler repeats the ignition sequence.
Then, adjust heating and hot water temperatures as desired via the appropriate controls.
