Protection Of Boiler Against Overheating - ATTACK DP STANDARD Instructions For Use Manual

The advantages
The boiler installation together with the accumulation tank offers several advantages:
- lower fuel consumption (up to 30%). The boiler works in full output to fuel burn-up when the
optimal operation is observed
- High chimney and boiler durability and minimum formation of acids and condensate
- Possibility of combination with another heating sources ( solar panels...)
- conjunction of boiler and floorheating
- confortable and ecological heating
Protection of the boiler against overheating
CAUTION: Cooling circuit against
overheating must not be used by STN EN
303-5 for other use than protection
against overheating.
Valve on the cold water inlet to cooling
circuit must be opened constantly and
the heating circuit has to be connected
with the functional cooling water
feeder (p.e. the cold water from water
supply) with the temperature of 10-
15°C and the pressure of 2-6bar. STS 20
valve which has a sensor placed in the rear
part of the boiler protects the boiler
against overheating. If the temperature of
water in the boiler overcomes 95°C, the
valve lets water into a cooling circuit
which overtakes excessing heat. In case
of boiler overheating and STS20 valve
opening the constant off-take of heated
water from heating circuit to waste piping
has to be assured.
Unsecured cooling circulation in the cooling circuit when the STS20 valve is opened,
can cause the boiler damage! In that case the guarrantee cannot be applied.
