3.16 SPECIFIC INFORMATION FOR CORRECT BOILER INSTALLATION IN COMMON
PRESSURISED FLUE SYSTEMS (C10 - C12)
The boiler is factory equipped with a flue gas non-return valve located downstream of the fan, this device, given the importance
of its correct operation, must have its installations C(10) and C(12) checked on an annual basis, and the active rubber element
must be replaced in case of cuts in the moving parts.
For safety reasons, the flue gas non-return valve must be replaced after 10 years of operation.
Before removing the sealing elements of the sealed chamber, using the flue gas analyser and with the boiler off, check that there
are no traces of combustion products in the flue gas sample point.
The presence of combustion products indicates that the non-return valve on the flue gas (in boiler exhaust) is not properly closed, in
which case it is appropriate to check the absence of flue gas even in the sealed chamber (analysis via air sample point).
If malfunctions are detected on the flue gas non-return valves, especially on the discharge valve, in the absence of a shut-off flue
adjusting device at the coupling point of the flue in the pressurised collective flue, it will be necessary to turn off all the boilers
connected to the pressurised collective flue itself, or make sure to intercept the connection point to avoid the dispersion of com-
bustion products into the environment.
Only then proceed to verify the components, making sure that the non-return valve siphon on the flue gas (on the exhaust) is
full and replacing them if malfunctioning or damaged.

3.17 BOILER COUPLING WITH WIRELESS ROOM PROBES

The kit concentrator with probe consists of two devices capable of communicating together via radio frequency. The radio association
between the two devices is not factory set.
It is necessary to perform the following operations at the time of installation, in order to activate radio acknowledgement and assign
room control to the correct zone.
The room probe will be positioned in the room where temperature control is required.
The room probe works with the use of two 1.5V AA batteries and does not require electrical connection via wires.
The concentrator must be connected to the boiler by wiring (supplied with the kit) and positioned near the boiler.
If necessary it can be placed away from the boiler; in this case, it is necessary to provide a suitable electrical connection (not supplied with
the kit).
