GEnErAL DEsCrIPTIOn
The latest types of the ATTACK cast iron gas boilers are marked as EKO, PLQ, KLQ, KLV, E, EZ, P.
These products achieve high level of the technical-economic parameters, comparable with the top
foreign products. Thanks to progressive design, with high efficiency and long life they attain very
low level of pollutants in the flue gas and therefore they considerably save the environment. In all
the modifications is used an automatic gas valve, enabling reliable, safe and economical operation
with minimum need for manipulation. The boilers are assembled from the control and regulation
elements from the top European manufacturers and cast iron bodies (consisting from 2, 3, 4, 5, 6,
7 elements). The ATTACK gas boilers are equipped with the high quality stainless steel burners. All
the ATTACK floor standing boilers are certified under the CE1015.
PurPOsE Of usE
The type line of EKO, KLV boilers is produced with the stable capacity of 9, 12, 15, 20, 25, 30, 35, 40,
45, 49,9 kW. The P type line is produced in the stable capacity of 9, 18, 25, 35, 45, 50 kW. The PLQ, KLQ
type ranges are produced in modulated capacity of 6–9, 12–15, 15–20, 18–25, 24–30, 28–35, 38–45,
42–49,9 kW. The E and EZ boilers are produced with the automatically modulated output of 6–9,
10–18, 16–25, 25–35, 33–49,9 kW. They are used for heating or central heating of family houses, flats,
shops and similar premises where the natural gas as fuel is used. The boiler is intended to operate
with the heating water of the maximum hydrostatic pressure of 0,4 MPa (4 bar) in line with the STN
07 7401 norm (it must not be acidic, i.e. the pH value must be higher than 7 and the carbonic hard-
ness must be low) and operating temperature up to 90°C with connection to the heating systems
with forced or natural flow (marked as S or P).
For the domestic hot water preparation there are the indirect heated floor standing hot water
tanks of the same design as the ATTACK floor standing gas boilers.
