Technical Description - ATTACK SLX20 Instructions For Use Manual

 We recommend to connect the boiler with accumulation tank with minimum volume of 70 l
to 1 kW boiler output.
 Use only dry fuel with 12–20 % moisture (with higher fuel moisture is decreased boiler out-
put and increases its consumption)
 Right choice of the boiler size, i.e. its heat output, is very important condition for economical
operation and correct function of the boiler. Boiler has to be chosen according to its nominal
output, which must meet the heat losses of the heated object.
WARNING: Boiler might be used only for intended purpose and only in the way de-
scribed in this manual.
CAUTION!: After the boiler disconnection from electricity mains during the operation,
burning continues in the sustain mode. Do not open the boiler door until the tempera-
ture drops below 40 °C.
The boiler warranty is not valid, if:
 Is not operated with prescribed fuel
 In the system is not installed the mixing device ATTACK – OVENTROP, which ensures the
backflow water temperature to the boiler at least 65 °C during the operation
 Functional thermostatic valve wont be installed at the aftercooling circuit of the boiler (e.g.
WATTS STS20) and then connected to the source of the cooling water.
 Boiler is not installed according to the requirements stated in this manual, e.g. correct di-
mensions of the chimney etc.
 Is not sufficiently cleaned according to the instructions given in this manual
This appliance is not intended for use by persons (including children) with physical, sensual or
mental disability or insufficient experience due to which they are not able to use the device in a
safe way without being supervised or instructed about the boiler operation by the person re-
sponsible for their safety. Do not to allow children to play with this appliance.
If the power supply cable is damaged, it must be replaced with the correct type of
the cable, which is available by producer or by a service technician!
Be careful during the work with this appliance! Lambda probe works by high tem-
peratures (300 °C) and you might get burned during careless manipulation!

1.5 TECHNICAL DESCRIPTION

Boiler is constructed for wood combustion, based on the gasifying with use of exhaust fan,
which makes forced flow in the boiler and sucks the flue gas out of the boiler. Boiler body is
made as the weld from steel plates of 6 mm thickness. In the upper part of the boiler is feeding
chamber with above-standard volume, equipped with dry sheath technology, which lowers the
condensate creation and prolong lifetime of the boiler. In the bottom part of the feeding cham-
ber is fireproof nozzle with longitudinal hole for crossing the wood gas to the combustion
chamber. Secondary air is brought by the nozzle and after mixing with wood gas creates burn-
ing in the combustion chamber. Combustion chamber is also the ashtray, where are collected
wastes after combustion (ash). In the rear part of the boiler body is tubular exchanger equipped
with turbulators, which serves for cleaning the exchanger and increasing the boiler efficiency.
Turbulators might be controlled manually or automatically (using engine) according to the
boiler version PROFI or LAMBDA Touch. In the upper part of the boiler is situated boiler regula-
tion, which controls the wood gasification process and offers all important information about
