8. Versions
Heaters with spring fireplace door can be connected to a chimney with multiple taking for other heaters and
fireplaces provided that dimensions of the chimney are in compliance with DIN 4705 part 3.
The door of the heater with spring fireplace door must always be closed during operation, except for firing, fuel
charging, and ash removing. Otherwise operation of other equipments connected to the chimney may be affected
or flue gas may leak.
9. Combustion Air
Since heaters 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.
10. Fire Protection
Distance from flammable structures and furniture
To assure adequate heat protection, a minimum distance of 20 cm in the back and 40 cm on the sides is required
between the heater and flammable structures and furniture.
Fire protection within radiation perimeter
Make sure that no flammable structures or furniture are within radiation perimeter of glass door, which is 80 cm.
The distance may be reduced to 40 cm if safety shade is installed between fireplace and flammable structures
leaving enough space on both sides.
Fire protection outside radiation perimeter
Minimum distances from flammable structures and furniture are stated on heater’s label and must be observed.
Heater
For solid fuel heaters floor in front of fireplace’s door made of flammable materials must be protected by a non-
flammable hearth. Its minimum dimensions are 50 cm in the front and 30 cm on the sides of fireplace door.
11. Spare Parts
Only spare parts approved or provided by the manufacturer may be used. For inquiries, please, contact a specialized
vendor.
No modifications to heater are allowed!
12. Warning in case of fire in chimney
Deposit in chimney may catch fire if unsuitable or humid fuel is used. In such case close all heater air holes
immediately and call the fire brigade. After fire is extinguished chimney should be inspected by an expert for
cracks or untight places.
13. Nominal heating capacity, combustion air adjustment, and fuel burning time
Nominal heating capacity of heater is 8,0 kW and it is obtained at minimum supply pressure of 13 Pa.
