Description
Exhaust of combustion gases above the roof.
4
The opening for the air-supply inlet is located in the same pressure zone as the vent (For
4
example, a concentric passage to the roof).
Common channelling for the air-supply and exhaust of combustion gases (CLV):
Concentric.
-
Eccentric; Air supply from the shaft.
-
This also relates to the overpressure cascades.
4
Closed equipment.
4
Separate channelling for the air-supply.
4
Separate channelling for the combustion gases.
4
Terminating on different pressure surfaces.
4
The manufacturer delivers this type of equipment without a supply or exhaust system.
4
The equipment can be connected on a so-called semi-CLV system (with common combustion
4
gas exhaust).
Channel for the air-supply and exhaust fumes in a duct or surrounded by a sleeve:
4
Concentric.
-
Eccentric; Air supply from the shaft.
-
Exhaust of combustion gases above the roof.
-
The opening for the air-supply inlet is located in the same pressure zone as the vent.

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).
