2.3.9 Inspect/clean chimneys to which former
solid fuel boilers were once connected
We recommend that you have chimneys inspected and
cleaned by a chimney sweep before the flue gas pipe is
installed if these chimneys were previously used to divert
flue gas away from solid-fuel-fired boilers but should now
supply combustion air. If it is not possible to adequately in-
spect/clean the chimney (e. g. due to construction features),
you can
–
use a separate air supply or
–
use open-flued operation for the system.
2.3.10 Risk of corrosion in the product caused by
using a chimney to which the former oil-
fired boiler was once connected
Chimneys that previously diverted the flue gas away from oil-
fired boilers should not be used to supply combustion air.
The combustion air may be charged with chemical deposits
and this leads to corrosion in the product.
2.3.11 Risk of fire due to insufficient clearance
▶ Ensure that the flue gas pipe outside the shaft has a min-
imum clearance of 5 cm from flammable components.
2.3.12 Moisture damage caused by incorrect
installation location of the inspection elbow
An incorrect installation location leads to condensate leaking
from the lid of the opening for cleaning and may lead to cor-
rosion damage.
▶ Install the inspection elbow in accordance with the illus-
tration.
2.3.13 Moisture damage caused by incorrect
installation location of the inspection T-
piece
An incorrect installation location leads to condensate leaking
from the lid of the opening for cleaning and may lead to cor-
rosion damage.
▶
Install the inspection T-piece in accordance with the illus-
tration.
2.3.14 Material damage due to improper use
and/or unsuitable tools
Improper use and/or the use of unsuitable tools may result in
material damage.
▶
Always use a suitable open-end spanner to tighten or
undo threaded connections.
▶ Do not use pipe wrenches, extensions, etc.
