Installing The Stove; Operation - Olsberg Draco 28/895 Instruction Manual

Installing the stove

The floor on which the stove is installed must be even and
horizontal. The stove may only be installed on an adequate
load-bearing floor. The stove can be stood on a metal floor
sheet or glass sheet to protect the flooring.
If the flooring or carpet is inflammable, a stable and non-
combustible spark protection plate must be used. This
must extend 50 cm to the front and 30 cm to each side
beyond the edge of the combustion chamber opening.
Under the stove no spark protection plate is required.
Assembly sequence
● The Ø150mm stovepipe connection can be installed at
the top or rear. The stove is supplied ready for connec-
tion from above. If you wish to connect it at the rear, the
following steps must be carried out to make the neces-
sary modifications:
- Break out the cover in the back panel.
- Replace the connector sleeve and the sealing cover.
● Decide where the stove is to be installed. There must be
no objects made of combustible materials within a dis-
tance of 80 cm, of the stove's radiation area, measured
from the combustion chamber's inspection glass, nor
may any be placed within this area subsequently.
Depending on the installation position of the stove in
front of walls that need to be protected (flammable or
load-bearing), the following distances from walls need
to be observed in accordance with the position of the
combustion chamber door to the wall / side panel or
the back panel (see schematic diagram).
When not dealing with walls that need to be protect-
ed, you merely need to observe a minimum distance of
approx. 5 cm to allow for proper heat dissipation.
● Install the pipe lining (provided on site) in the chimney.
The connection height can be individually specified for
a top stovepipe connection, however should not exceed
1.5 m from the connector sleeve. For the rear stovepipe
connection heights please refer the "Technical Data"
chapter. No combustible material is permitted within a
radius of 20 cm around the stove pipe.
● Connect the stovepipe at both connection points with
stove putty so that the stove pipe is permanently sealed.
● Push the stove onto its planned position and orient it so
that the stovepipe fits into the pipe lining.
The stovepipe connections must be tight. The stove-
pipe must not protrude into the chimney.
Bear in mind that on partition walls in accordance with
test specification EN 13240 the temperature of 85°C
can be reached, and with light wallpaper or similar
combustible construction materials this can result in
colour changes.

Operation

Permissible fuels
The following fuels are approved:
● Natural shopped wood in the form of billet wood
Maximum length: .....................33 cm
Circumference: .......... approx. 30 cm
● Wood briquettes to DIN EN 14691
Size class HP 2
Maximum length: .....................20 cm
Billet wood reaches a moisture content of 10 to 15% after
being stored outdoors for 2 to 3 years (only covered at the
top) and is then ideally suited for heating.
Freshly cut wood has a very high moisture content and
so burns badly. Apart from the very low calorific value it is
also harmful for the environment. The increased conden-
sate and tar formation can lead to fireplace and chimney
sooting.
This diagram shows that the consumption rate with fresh-
ly-felled wood (calorific value 2.3 kWh/kg) is almost twice
as high as the consumption rate with dry wood (calorific
value 4.3 kWh/kg).

Moisture [%]
You will only achieve optimum combustion and heat in
an environmentally friendly way with these fuels. Adding
the fuel in small quantities avoids unnecessary emissions.
Clean burning can be identified by the fact that the fire-
brick becomes a light colour.
According to the German Federal Immission Control Act,
it is forbidden e.g. to burn the following fuels in stoves:
● Moist wood or wood treated with wood
preservatives
● Sawdust, chippings, grinding dust
● Bark and chipboard waste
● Slack coal
● Other wastes
● Paper and cardboard (except for igniting)
● Straw
Please note before heating for the first time
● Remove all accessories from the ash pan and combus-
tion chamber.
● The odour given off by the evaporation of the protec-
tive coating disappears after the stove has been burn-
ing for several hours (ventilate the room well).
● The stove has a high quality temperature resistant coat,
which does not achieve its final strength until the stove
has been heated for the first time. You should therefore
never leave anything on the stove and not touch the
surfaces as the paint coat could otherwise be damaged.
● As soon as the kindling material has burned down, put
on 2 burnouts consisting of 3 kg wood ensuring that the
temperature resistant coating reaches its final firmness.
Igniting
● Before ignition, check that no flammable objects are
placed on the stove.
● Empty the ash pan if necessary and slide back in.
● Open the combustion air slide valve complete.
● Grate in open position = operating lever pulled out
● Stack small amounts of firewood and, on top of it, kin-
dling material (igniter cubes and dry, smaller kindling)
and set the material alight.
● Close the door to the combustion chamber so that the
kindling material can catch fire.
● Once there is a basic firebed, add more fuel according to
the heat requirement (see chapter "Heating").
