1 Construction of the fireplace
1.1 Placement of the fireplace
The installation of fireplace insert starts with preparing a correct place for the fireplace
construction . It ought to be characterised with:
-
strength of the base (floor) appropriate to the type of insert and weight of enclosure
(on average, from 450 to 850 kg); the floor must be reinforced and/or the weight ought
to be distributed over a larger area, if this condition is not fulfilled,
-
the chimney with parameters (diameter and height) suitable for the type and power of
the insert (chapter 3) and it must be resistant to humidity produced during the
combustion process, and temperatures occurring during combustion of solid fuels,
-
adjustable supply of fresh air from outside the building (min. 200 cm²), conducted to
the room in which the fireplace insert is installed,
-
the place of installation should not contain any combustible materials or non-heat
resistant materials, electrical or hydraulic installations,
-
the fireplace must not be installed in a room with mechanical exhausts (ventilation)
„If
the fireplace can be installed in a room with mechanical ventilation, please observe
local regulations.
-
floor under the fireplace and 60 cm in front of the fireplace must be made from
incombustible materials (e.g. terracotta or natural stone).
Once the place of installation is prepared as above, construction of the fireplace pedestal
constituting the fireplace foundation may proceed. The pedestal structure must guarantee
unobstructed flow of air from underneath, along external walls of the insert and upwards,
ensuring the minimum air flow section required for the given type of insert (table 4). If the
insert does not have its own supporting structure, the pedestal constructed as above may
become its foundation. While placing the insert, make sure that the insert base does not limit
the required air flow area (figure 1).
