Sophisticated condesing technology –Completely equippedWithout flue gas fanWith flue gas fann The boiler and combustionchamber consist of high-qualitysteel. With the specific profiledflue gas baffles you arrive at anoptimum of heat tranfer to theboiler water.The cleaning is simple and fastdue to the pivoted combustionchamber and flue gas door.n Modular and compactconstruction:The second, highly effectivetube heat exchanger made ofa special plastic, with fitted gapto enable easy flushing of theheat exchanger when servicingis carried out.Here, the bulk of the latentenergy will be extracted fromthe flue gas.As the incoming combustion airenters the heat exchanger,the flue gas will cool down underapprox. 47°C. n Heating also without flue gas fan:There are situations and siteswhere there is so little counterpressure on the chimney thatthe condensing boilers will alsowork perfectly without a flue gasfan. Therefore, Kroll offers theBK 20 and BK 30 also withoutflue gas fan.The following has to be observed:• Flue gas unit• Must be within the maximumlength according to the Krolldocumentations• Combustion air supply• Geodetical height• Must not be higher than1000 m above sea level
