Air inlet
For correct operation of the boiler it is necessary to ensure sufficient air supply for burning.
There must be an opening for the air inlet for burning of at least 200 cm
2
depending on the
boiler output.
Boiler connection to the heating system
Only a trained technician can install and service the ATTACK DPX boiler. Before installing the
boiler, it is necessary to flush (to clean) the whole heating system. The system can be filled only
the water treated to the values under the STN 07 7401: 1992. Callosity of the water must not
excess 1mmol/l and concentration of the Ca²
Ѐ
must be lower than 0,3 mmol/l.
If these conditions are not kept, the warranty is not valid!
Chimney
Connection of the appliance to the chimney hole must be always done with permission of the
appropriate chimney sweep association. The chimney must generate sufficient draught and take
the flue gas out into the atmosphere under the all operating conditions.
Correct dimensions of the chimney hole are important the correct boiler function, because the
burning, output and boiler life-time are influenced by the draught. The chimney draught directly
depends on its diameter, height and roughness of the internal wall. It is not allowed to connect
any other appliance to the chimney, where the boiler is connected. Diameter of the chimney
must not be smaller than the connection part on the boiler. The chimney draught must achieve
the prescribed values, but it cannot be too high, not to decrease the boiler output and interrupt
the burning (flame). If there is too strong draught, install the throttle flap into the chimney hole
between the boiler and the chimney.
Prescribed dimensions of the chimney section:
20×20 cm
min. height 7 m
20 cm
min. height 8 m
15×15 cm
min. height 11 m
16 cm
min. height 12 m
The exact chimney dimension is defined by the STN 73 42 10. The prescribed chimney draught is
given in the Technical parameters.
Flue gas connection
The flue connection must lead into the chimney hole. If it is not possible to connect the boiler to
the chimney hole directly, then the appropriate extension should be as short as possible, of up
to 1 m length, without any additional heating area and it should ascend in direction to the
chimney. The flue connection must be mechanically tight (it should be mounted to the boiler
and tightly fixed by screws) and tight against the flue leakage. The flue connections must to lead
through the foreign dwelling or commercial premises. The internal diameter of the flue
connection must not taper in direction to the chimney. It is not suitable to use the elbow
connectors.
Boiler connection to the electricity mains
The boiler is connected to the electricity mains of 230V/ 50Hzby an electrical cord with plug. In
the case of need, the power supply cord of the M type must be replaced with an adequate one
by the service organization.
The appliance must be placed in the way enabling to reach the connection plug. The boiler must
be connected to the 16A socket circuit by a circuit breaker (following the STN EN 60 335-1 +
A11:1997).
