low-NOx, wall-mounted boilers which heating and domestic hot water production. The main elements choices made by – the low NOx burner combined with a copper heat exchanger,

which operates at the same time as the heat pump, for space heating, and a rapid heat exchanger for domestic hot water (DHW) production

– a “type C” combustion chamber, sealed off from the environ

ment in which the boiler is installed

– the microprocessor electronic control board, which makes

the heating and domestic hot water production system easier to manage. The appliance has just one heating request input, which ambient thermostats or a remote control can be con nected to. In the latter case, the boiler temperature varies on the basis of the e lected optimal climatic curve. This provides signiﬁcant energy

t savings.

and c Other special features of the – the anti-freeze function which activates automatically if the

temperature of the water inside the boiler falls below the

threshold of the value set at parameter "PAR 10" and , if there

is an external sensor, if the external temperature falls below

the threshold of the value set at parameter "PAR 11" – the anti-blocking function of the pump and diverter valve, this

activates automatically every 24 hours if no request for heat

has been made – domestic hot water comfort function which allows the time

necessary for the hot water to become available to be reduced

8.4 Checks

8.4.1 Checking the smoke duct

It is recommended that the user checks that the combustion air inlet duct and smoke outlet duct are integral and airtight.

8.4.2 Checking the expansion vessel pressure

It is recommended that the expansion vessel on the water side is drained and that the preﬁlling pressure is not less than If this is not the case, pressurize it to the correct value (see sec-

tionExpansion v Once the checks described above have been completed: – reﬁll the boiler as described in section "REFILL operations" – start the boiler up and carry out a smoke analysis and/or

measure the combustion efﬁciency.

8.5 Reading the pressure at the nozzles with the chimney sweep function

Should the pressure at the nozzle need to be checked, a qualiﬁed maintenance technician can activate the chimney sweep function described belo

This function lasts 15 minutes and is activated by proceeding as follows: – if the panel (2) has not already been removed, remove the

two screws (1), pull the front panel (2) forwards and release it from the top by lifting it
