10. "Room-sealed" operation

If the appliance is operated independently of indoor air, the follow-
ing instructions are also to be observed:
• Room-sealed operation is only possible if combustion air is pro-
vided from outside.
• According to the assessment criteria of the DIBT in Berlin and the
DIN 18160 standards, fireplaces with an external supply of air for
combustion are only allowed if only one appliance is connected
to the chimney.
• The combustion air supply duct from the outside or from the air
shaft of an air-flue gas chimney as well as the connecting piece
to the chimney are constituent parts of the stove and must cor-
respond with FC41x and FC51x. The connecting pieces air / exhaust
gas must comply with DIN EN 1856-2 (pressure class N1, permis-
sible leakage rate < 2 l/s m2).
• The air supply duct provided by the customer must be tight (e.g.
steel pipe to DIN 24145, flexible, non-combustible aluminium hose
• Make sure that the pipe connection for supply air and exhaust gas
are leak-proof.
• The chimney flue must be sealed at the pipe connection by means
of a temperature resistant sealant.
• The flue pipe must have a gas-proof connection to the chimney
and must be sealed by means of an appropriate rope seal and a
temperature resistant sealant (e.g. heat-resistant silicone).
• The total length of the connecting pipe between appliance and
chimney should not exceed 1.5 m.
11. Requirements for the room where
the appliance is situated

Load-bearing capacity of the floor

Prior to installing the appliance, make sure that the substructure of
the floor is suitable for the weight of the appliance. Ensure a level
and vibration-free positioning of the appliance.

Room temperature and ambient temperature / humidity

The appliance can be operated in dwellings with normal air humidity and
room temperatures of + 5 °C to + 20 °C.
The appliance is not protected against water spray and must not be
installed in wet rooms.

12. Safety clearances

(Fig. „D" on page 3)
The following safety clearances to combustible items (movable
wooden walls, furniture, furnishing fabric, etc.) must be maintained:
A 15 cm Clearance to wall at the rear
B 30 cm Clearance to wall at the side
C 100 cm Area of heat radiation
13. Floor pad as a protection against
flying sparks
(Fig. „16. Adjustment of the air supply" on page 19)
With combustible floors (timber flooring, synthetic materials, fitted
carpet, etc.), the use of a floor pad made of safety glass or similar
non-combustible materials is recommended
According to fire protection laws, the minimum size for this pad
must be observed.

14. Fuels

The appliance is designed for burning firewood (logs).
Use bark waste, sawdust, fine wood chips, brushwood, wood-wool,
wood shavings and paper only in small amounts to start a fire when
operating the appliance with firewood. The burning of such fuels
results in significant pollutant emissions, large amounts of ash, and
the heat output is comparatively low.
FIREWOOD (LOGS)
Firewood should have a moisture content of approx. 20 % of the dry
weight, a length of 1/3 m and should be split into small pieces. This
way, the firewood quickly catches fire and produces a higher heat
output than the same volume of large logs. Spruce wood, fir wood
or alder wood should be allowed to dry out for at least 2 years,
hardwood as long as 3 years (under a roofed shelter).
The effect of the water content in wood on the calorific value is
shown in „Tab. 1":

stored for one winter

Prohibited fuels

Surface-treated wood (veneered, painted, impregnated, etc.), particle
board, all types of household waste (packaging waste), plastic mate-
rials, newspapers, rubber, leather, textiles, etc.
Burning these materials is harmful to the environment and is there-
fore prohibited by law. Furthermore, damage to the appliance and
the chimney can occur.
Furthermore the combustion of coal and similar fuels is not permit-
ted. The appliance has not been tested for use with these fuels;
therefore damage to the appliance cannot be ruled out and is not
covered by warranty.
PLEASE NOTE: Damage resulting from burning prohibited fuel is not
covered by warranty.

15. Operation

Accessories supplied by the manufacturer

To ensure a safe operation of the appliance, it comes with a grate
lifter and a cleaning brush.

Closing the heating door

The door of the appliance is self-closing and self-locking. To open
the heating door, press the integrated release button fully while pull-
ing on the door handle. When closing the heating door make sure
that it engages with an audible click. Check: It must not be possible
to open the door simply by pulling on the door handle.

Opening the fuel drawer (Kesar)

The fuel drawer is equipped with a „tip-on" catch; all it takes is a
gentle push on the front of the fuel drawer and the drawer opens
(Figure 13). To close the drawer, gently push the front of the fuel
drawer again until the lock engages.
