The combustion products venting can be led in two ways according to the following figures:
Fig. no. 15
Combustion products venting in a direct design
Fig.no.16
Combustion products venting in a combined design
We recommend to use the variant according to Fig.no.15 if the boiler is designed in the way making sure it
observes the max. height H = 1,5 m and calculations according to tab. no. 9. This design has a minimum
pressure loss.
Fig.no.16 shows an example of a combined design assembly with individual elements. The calculation
according to tab. no.9 must be observed it means the max. value of flow resistance coefficient must not be
exceeded.
The combustion products draw-off ventilator (OSV) is put on the boiler draught diverter neck or on the
smoke-flue vertical tube inserted in the neck of the draught diverter. The neck extension must be direct and
vertical, its diameter must be the same as the diameter of the neck and it must not be longer than H - 1,5m.
