3.8 Condensate outlet
The boiler is fitted with an odour closure (siphon), which must be flooded before running the boiler with about 200 ml of
water. Firstly, it is necessary to connect neutralizing equipment to the outlet for the condensate and then to discharge the
condensate to the sewerage piping. The discharging of the condensate into the sewerage piping is governed by national or
regional (local) regulations.
The collection piping must have a minimum declination of 5° from the boiler into the sewerage piping and must not be blocked
(in the case of blocking the collection of the condensate, there is resonance of the combustion chamber of the boiler chamber).

3.9 Design of gas exhaust
The exhaust for burnt gases of these types of boilers must be designed by means of the certificate smoke collection system
delivered by the producer. From the viewpoint of checking the route for burnt gases, it is necessary to ensure that the
exhaust for burnt gases has a suitable revision hole. The exhaust for burnt gases and any connection to the chimney must be
in accordance with ČSN 734201. The actual performance of the exhaust for burnt gases must be designed and prepared in
the project for the connection of the boiler while respecting the standard rules for collection of condensate. The horizontal
piping must be installed with the slope 2° from the terminal unit in the direction from the boiler to prevent any escape of the
condensate (and possible freezing) from the terminal unit of the exhaust into the surroundings.
For THERM 90 KD.A condensing boilers, the following methods for the collection of burnt gases are approved:
a) coaxial smoke collection tube with a diameter of 110/160 mm
b) separate smoke collection tube with a diameter of 2 x 110 mm
Mininum length of smoke collection is 1 m. The first knee in the case of horizontal smoke collection is included into the
maximum length of smoke collection. The second and subsequent further knees shorten the maximum length by:
0,5 m - knee 45°
0,75 m - knee 90°
