decisions regarding the repair work of the chimney shall be the chimney-sweep's / expert's domain, prior to
providing positive feedback for the installation of the biomass furnace.
Figure 1
-
The smoke can be channelled off directly into the exhaust pipe (chimney) only if the cross section reaches
20 x 20 cm or a diameter of 20 cm and a cleaning / inspection hatch is installed.
-
If the
cross section of the chimney exceeds
20 x 20 cm or the diameter exceeds 20 cm, the potential
regulation of ventilation (more or less air) can be done in three ways:
1.
An automatic negative pressure regulator should be installed at the base of the chimney;
2.
Install a 10 cm diameter steel pipe into the chimney, if you have the elements needed for such a
modification.
-
Ensure that the attachment of the chimney is sealed correctly.
-
Avoid contact with flammable materials (such as wooden bars: in any case, the structure must be
insulated with a heat-resistant material, refer to figure 2).
The furnace is manufactured to comply with 80 mm exhaust pipes attachments for the chimney. If you use a
non-standard, newer chimney and you are currently modifying the existent structure, use insulated stainless
pipes (triple layer wall). The diameter should match the one in table 1. Flexible tubing is prohibited.
