4.8.2. Outlets
in general, it is possible to use a standard kit for passage via the roof
or outside wall. In the case of such passage via the outside wall
directly above the boiler, use the Remeha kit for passage via an
outside wall. This is available as an accessory.
For exhausting combustion gases of types C1, C3 and C5, it is
appropriate to use a
M&G Skyline / Mugro 3000
or a
Coxstand E
HR
. When exhausting combustion gases of type C6, the material of
the exhaust must conform with Gastec QA and/or be provided with
CE marking.
The exhaust vent for combustion gases must conform to EN
1856-1. The flue gas pipes must be calculated conforming to EN
13384 (parts 1 & 2).
