C) Supply of combustion air from above. Air supply from above can only be performed with tested chimney systems.
In this case, it is necessary to calculate the dimensions of the chimney!
D) Supply of combustion air directly from outside. If combustion air is directly supplied through the outer wall, it shall be
only be slightly preheated, which is unfavorable for a clean combustion. In this case there is also risk of condensation!
NOTE: We do not recommend these versions of air supply! However, if you use these options, consult a qualified
professional.
In the room where the heating device is installed, it is necessary to ensure sufficient supply of fresh air. If the windows and
doors are hermetically sealed or if there are air-extracting devices, such as hoods, hair dryers, fans etc., in the room where the
range is installed, combustion air (fresh air) must be supplied from outside. In any case, this should be discussed with a
competent chimney sweep before installing the range.

6. FLUE INSTALLING
Review the unpacked solid fuel and become familiar with the parts of the solid fuel and the accessories, and especially pay
attention to the following:
- The special channels of the firebox door, the ashtray, the cover for cleaning and the hob frame should have pigtails with
no asbestos that seal well and do not allow uncontrolled air intake.
- The combustion regulator (thermostat) with regulation knob (fig.1 pos.10) should properly open and close the regulator
flap (fig.1 pos.19).
- The ember holder (fig.1 pos.13) should be properly placed in its bearing and should be easily open.
The flue connection (plug), that is delivered together with the solid fuel and is placed in the drawer for wood, should be set
and screwed on the openings of the plug carrier (hob) or on the opening on the lateral side. The existing cap must be
previously removed and the same screws for connecting plugs should be used.
WARNING:
If Your flue is not the best or it is with suspicious quality, we recommend that You install a flue connection on the plug
carrier (from the top), and not on the side.
The flue reaches its rated power if the flue draft is 15,5 Pa. We recommend the following flue sizes with which this draft is
obtained:
Dimensions of light surface (mm.)
- Proper flue and meeting other requirements set out in the material that follows are a prerequisite for flawless functioning
of the solid fuel.
- The flue connection should be installed with uplifting.
- Horizontal flue pipe pieces longer then 0,5m should have an uplifting of 10 towards the flue.
- The flue extension, flue pipes and the flue must not be narrowed.
- All connections as well as the flue must be well sealed, with no soot and grime in flue pipes.
- The flue should be protected from cold (it should be heat insulated). This especially applies for flues made of sheet metal
and flues built on external walls.
- Flue pipes that do not have thermal insulation and do not stand vertically, must not be longer then 1,25m. Check of the
draft strength is performed by using candles (fig. 2).
