Flue gas exhaust
The hot ‐ water fireplace insert must be connected to a separate chimney, to which no other stove
or UT boiler can be connected, see CSN 73 4210.
The active chimney diameter required is 180 mm; the required draft is 12 Pa. This corresponds to
an effective chimney height of approximately 5 m (measured from the collar to the chimney opening).
Besides basic technical parameters, the chimney draft is also affected by various other factors, such as
weather, location, chimney humidity, age, installation... If in doubt whether the given chimney is sufficient,
consult a chimney sweeper.
If the draft exceeds 15 Pa, we recommend an additional reduction of draft by choking the
secondary air intake with the installation of an additional flue gas shutter or draft regulator of air intake
into the smoke flue.
If, on the contrary, the chimney draft is too low, we recommend using a chimney ventilator.
The smoke flue is used to exhaust flue gases from the smoke outlet of the appliance into a pipe or
open space. The smoke flue should be as short as possible, with fluid changes in shape and minimum
surface irregularities. Pursuant to CSN 73 4101, it should not exceed a length of 3 m *); if the length
exceeds this limit, it needs to be equipped with insulation to ensure minimum heat resistance of 0.55
m2.K.W ‐ 1. Choose smoke flues with a cleaning opening that allows you to clean and check the flue. Smoke
flues must not be conducted to other floors, apartments or areas where the installation of fuel appliances is
not permitted. Smoke flues can pass through walls. If the wall is made of flammable structural materials or
contains flammable components, the smoke flue must be surrounded by non ‐ flammable material with very
low heat conductivity (CSN 06 1008).
The minimum distance from the smoke flue to flammable materials is regulated by CSN 06 1008.

Distances may be reduced to up to a quarter, if the smoke flue is equipped with at least 2cm thick
sheathing made of non ‐ flammable material
Before starting a fire for the first time, everything needs to be inspected by a chimney sweeper,
who will issue an inspection report.
b) Air intake
The fireplace insert is equipped with a central air intake (CAI) for supplying the air necessary for
combustion from the outside or alternatively another room, e.g. a cellar.
CAI is connected to the fireplace insert by a minimally 1m long aluminum flexible pipe with an inner
diameter corresponding to the outer diameter of the CAI flange, which may then be continued with any
pipe (including plastic) resistant to a temperature of 80°C. The length of the intake pipe should not exceed
5 ‐ 7 m. We recommend fitting the inner surface with insulation to prevent condensation of air humidity in
the interior at low temperatures of intake air (air from outside during winter). Try to avoid bending
(elbows), each bend exceeding 90°C may reduce the draft by up to 15 %.
