(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 parallelly with the heater.
10. Fire Protection
Distance from flammable structures and furniture
To assure adequate heat protection, a minimum distance of 15 cm in the back and 20 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 10 Pa.
Fuel
Wood logs
(25 cm length, 30 cm circumference)
Lignite briquettes
Maximum dose 2,2 kg/hour 1,7 kg/hour
Slider pull out 10 mm fully open
Burning time 1.0 hour 1.0 hour
When burning wood, set the slider (pull out to 10 mm) so that the primary combustion air intake is completely closed and the secondary
combustion air intake is fully open.
When burning lignite briquettes set the slider (pull out completely) so that both primary and secondary air intakes are fully open.
The combustion air slider is below the firing door.
Quantity and adjustment of combustion air for moderate operation:
Fuel Lignite briquettes
Maximum dose approx. 1,7 kg/hour
Slider open at 5 mm
Burning time approx. 2 hours
14. Space Heating Capacity
For rooms with insulation non-conform with calorific insulation regulations space heating capacity should be determined pursuant to
DIN 18 893 for nominal heating capacity of 8 kW:
in favourable heating conditions
- 190 m
3
in poor heating conditions - 145 m
3
in unfavourable heating conditions - 98 m
3
For occasional heating – interrupted for more than 8 hours – space heating capacity is reduced by 25%.
