1.3 Connection to the chimney
At installation comply with all corresponding project, safety and hygienic regulations according to the Regulation No. 84/97.
Data to calculate the chimney (at the nominal thermal power):
Fuel
Wood
Brown-coal briquettes
Flue gas flow [g/s]

17.1
Max. flue gas temperature behind exhaust throat [°C]
427

The fireplace can be used to connect a multi-occupied chimney, which means that to the chimney with the fireplace connected,
we can connect more devices.
Before connecting the fireplace, make sure there is sufficient blast in the chimney. Flame of a burning paper or candle should
be sucked into the chimney opening. The fireplace should be attached to the chimney flue in the shortest direction.
The fireplace should be attached to the chimney flue always with the consent of competent chimney sweeper office in
compliance with STN 73 4210 and STN 73 4201.
If the fireplace cannot be attached to the chimney flue directly, the flue involved should be the shortest possible and ascend
towards the chimney. Flues can be of maximum 1,5 m length. In any case, it is necessary to ensure smoke tubes and bends,
mounted on exhaust throat, against getting loose by a pin. Smoke tubes and bends must be attached firm and tight to the
fireplace and plugged into each other by minimum 40 mm length in the direction of chimney blast. The chimney opening must
be fitted with a sheet metal case with a diameter corresponding to the diameter of used smoke tubes.
Correct and incorrect connection of fireplace to the chimney is displayed in Figure Nr.1.

To ensure a failure-free operation, the chimney blast must be kept at 12 Pa (measured inside of smoke tube behind the
fireplace). As the chimney blast can be affected by changeable factors, as the outside air temperature, combustion
temperature, chimney lining, wind power, etc., it varies during the year. Therefore it is recommended to install a damper inside
of the chimney.
The fireplace can reach the specified performance and efficiency as long as it is connected to a chimney with sufficient blast
draught. The chimney´s cross section must be 150x150 mm, and minimum height 5 meters.
1.4 Combustion Air
Since fireplace are fireplaces depending on surrounding air and take combustion air from the room, adequate intake of
combustion air is vital.
In rooms with tight windows and doors (e.g. as energy-saving measure) fresh air intake may be low and thus affect draught of
the heater. Also your well-being may be affected; even your safety may be threatened. It may sometimes be necessary to
assure adequate intake of fresh air e.g. by installing air shutter close to heater or by combustion air pipe leading to exterior or to
a well aerated room (except boiler room). In particular it is vital that combustion air pipes are open during operation of fireplace.
Steam flues located in the same room with fireplace may affect heater’s operation (smoke may leak to inhabited room despite
closed fireplace door) and therefore must never be operated parallely with the heater.
The outdoor combustion air could be supplied to the heater through the connecting socket which can be mounted on the
bottom of the backside of the heater.
The fireplace needs for wood combustion up to 20 m
3
of fresh air per hour.
Insufficient air flow runs counter to proper operation of fireplace and is a threat to your safety!
Let the installation of your fireplace, its connection to chimney and venting be tested by a competent chimney sweep
in your area!
1.5 Fire safety
It is obligatory to strictly adhere to the rules of fire safety covered by STN 92 0300.
