Information for C10 and C12 installations
e appliance is suitable for operation in a C(10) or C(12) system and only with the supply of methane gas (2H and 2E categories).
e appliances are developed to operate on collective pressurised ues with a safety pressure at the minimum heat input of 25 Pa and a
safety pressure at the maximum heat input of 100 Pa.
In boilers installed in type C(10) or C(12) ue systems, the parameter "Enable klapet valve" must be enabled, which will require
quick calibration. is is the only calibration operation permitted as CO2 emission levels are aected by the operating pres-
sures induced in the collective ue, with particular reference to the minimum heat input or any recirculation phenomena in-
duced by the ue system.
e appliance must be connected to a ue system designed by a heating engineer in compliance with the local regulation in force.
e collective ue system must be suitably sized to allow the appliance to operate with the following specications with which it was de-
signed:
- the maximum pressure, when n-1 appliance is working at maximum heat input (with n= number of total appliances connected or that
can be connected to the same collective duct), and a boiler works at minimum heat input, is 25 Pa;
- ue gas mass at maximum heat input;
- ue gas mass at minimum heat input;
- the minimum pressure dierence allowed between the combustion product outlet and the combustion air inlet is -200 Pa (- 400 Pa for
C12) including -100 Pa (-300 Pa C12) of pressure generated by wind;
- the duct must have been sized with a nominal temperature of the combustion products of 25°C.
- the maximum allowed recirculation rate for wind action is 10%;
- the common ue must be certied to admit an overpressure of at least 200 Pa (minimum pressure class P1);
- no draught-breaker devices must be provided in the duct system.
In particular, at the coupling point to the pressurised collective ue, a plate must be visible showing at least the following technical infor-
mation:
- the name and trademark of the common ue gas pipe manufacturer;
- suitability to work with C(10) or C(12) certied boilers;
- the maximum ue gas mass value allowed in kg/h;
- the dimensions of the common duct (collective pipe);
e openings for combustion air and the inlet of combustion products of the pressurised collective ue must be closed and their
tightness must be checked when the appliance is disconnected.
e appliance connection to the pressurised collective ue must be made as instructed, without exceeding the specic maximum exten-
sions stated.
e appliance ue gas duct must be tilted a few degrees towards the boiler, to facilitate the evacuation of condensate.
e appliance ue gas outlet must be installed with the ue gas non-return valve kit, which ensures correct operation of the ap-
pliance and facilitates its maintenance operations.
Furthermore, the safety sticker must be axed on the front casing. is sticker is contained in the appropriate Kit C(10) C(12), which
contains the additional exhaust ue gas non-return valve, necessary for the pressurised collective ues.
e sticker indicates the following information in language:
It is advisable to ax the sticker in a clearly visible position on the front casing.
- e installation of this appliance is of type C(10) or C(12).
- Before proceeding with maintenance operations, it is crucial to read the instructions provided in the manual.
- Set item Enable klapet valve to "Yes".
When the sealed chamber is opened, combustion products may escape even when the appliance is turned o.
