Alarko ACK2 - Fuels; Flue Gas Exhaust System

ACK2 and ACK3 boilers can be fired with the fuels; Oil (according to DIN 51 603
and/or to local limitations), Natural gas, LPG and Town gas (according to EN 437
and/or to local limitations).
FLUE GAS EXHAUST SYSTEM
ACK2 and ACK3 boilers are B
23
type appliance so the flue gases must be
connected to an adequate draught chimney, without any flue gas leakage to the
boiler room. Chimney design must be according to local codes. Chimney inside
diameter, height, material, thermal insulation, strength shall be according the flue
gas specifications and shall not cause dangerous high pressures.
0 to -0.3 mbar vacuum shall be observed at the flue gas exit of boiler.
Some informative diagrams are given for quick reference in annex
Effective chimney height is the height difference between boiler flue gas exit and
chimney end.
Flue gas ducts between boiler and chimney shall not be longer then ¼ of the
effective height but anyhow it shall not be longer then 7 m and shall not be shorter
then 0.6 m. There can be maximum two 90° elbow (avoid sharp turns)
Flue gas ducts shall not have any downward slope. It is advised to have 10° slope
upwards and enter the chimney with an angle of 45°.
