3.1. Chimney
As manufacturer of fire inserts we allow/recommend the
following tolerances for new chimneys with triple isola-
tion:
- 180 mm, 200 mm chimney diameters may be reduced
by 20 mm from an effective chimney length of 8 m
- 250 mm chimney diameter may be reduced by 50 mm
from an effective chimney length of 8 m
- 160 mm, 180 mm chimney diameters for
«MERKUR» and «VENUS» must not be reduced
- 200 mm chimney diameter for “VENUS HK right/left”
must not be reduced
However, we recommend not to use chimney cross sec-
tions exceeding the specifications. Otherwise the follow-
ing faults may occur:
-
excessive cooling down of flue gases resulting in
possible condensation in the chimney
-
insufficient chimney draught
If smaller cross sections are determined according to
chimney calculation programmes, the installation is at
the own risk of the fireplace/tiled stove constructor.
3.2 Outside/fresh air
As manufacturer of fire inserts we request in general that
all systems must dispose of the outside/fresh air quanti-
ties specified. Otherwise trouble-free operation will not
be possible. If, according to the combustion air calcula-
tion, smaller cross sections are determined, their instal-
lation is at the own risk of the fireplace/tiled stove con-
structor.
