MODIfICATIOns Of ThE CAsT IrOn GAs bOILErs
Adequately to the project requirements, it is necessary to choose a suitable boiler type and out-
put. Therefore we produce boilers in various modifications:
ATTACK EKO – floor standing cast iron boiler with permanent flame controlled by a thermocouple.
ATTACK PLQ – floor standing cast iron boiler with permanent flame controlled by a thermocou-
ple and two-stage output regulation controlled by a switch on the front panel.
ATTACK KLV – floor standing cast iron boiler with electric ignition controlled by the ionization
electrode. The function of the boiler is similar to the one of boilers with permanent flame, only the
burners are ignited electronically after turning the boiler (or room) thermostat on.
ATTACK KLQ – floor standing cast iron boiler with electronic ignition controlled by ionization
electrode with two-level output regulation controlled by a switch. The function of the boiler is
similar to the one of boilers with permanent flame, only the burners are ignited electronically after
turning the boiler (or room) thermostat on.
ATTACK E – floor standing cast iron boiler with electronic ignition controlled by ionization elec-
trode. The boilers are made with modulation system (graduated modulation) which is automati-
cally controlled transition between two output levels of the boiler in the range of 65–100 %.
ATTACK EZ – floor standing cast iron boiler with electronic ignition controlled by ionization elec-
trode. The boiler is made with modulation system (fluent modulation) which is automatically con-
trolled transition between two capacity levels of the boiler in the range of 65–100 %. The boilers
are equipped with additional regulation that adjusts a three-way valve and starts heating the hot
water tank after the water tank temperature gets under 60°C .
ATTACK P – non-electrical floor standing cast iron boiler with permanent flame controlled by
thermocouple. This boiler is intended for a system with natural flow only.
COnDITIOns Of InsTALLATIOn
A gas boiler can be installed only by an authorized company. Before installation is the installation
company obliged to check the correct choice of the boiler type with regard to the functional at-
tributes and required parameters. There is no expanse vessel nor safety valve installed in the boiler.
The installation must be done in line -with the valid norms and prescriptions - see ČSN EN 1775, ČSN
33 2000-7-701, ČSN 06 1008 and ČSN 38 6460. The door in the room where the boiler is placed must
be open outwards. Because of service works, there must be free space around the boiler of at least
1x1 m in front and 4 m by the both sides.
The boiler must not be installed in dusty, wet, aggressive environments which should cause
damage and clog of burner and exchanger parts. The boiler must stand on a solid base (concrete
floor, tiles, etc.). Cleaning of the boiler must be done in a dry way only (e.g. vacuum cleaning).
Following the norm ČSN 33 2000-3, there must be ordinary environment in the boiler room,
protected from frost with the air temperature within the range of +5 - + 35 °C and relative moisture
up to 80 %. The combustion air must not contain halogen hydrocarbons and vapours of aggressive
substances, it must not be wet and dusty.
