Installation

Check to make sure that the load-bearing capacity of the in-
stallation surface is sufficient. If necessary, using a floorplate
to distribute the load can increase the load bearing capacity.
If the Luno will be operated as a room air dependent stove,
please check and ensure that the room where it will be instal-
led has a sufficient supply of combustion air. If the windows
and doors are tightly sealed, the necessary supply of fresh
air may not be ensured, which can interfere with the draught
capability of the stove and chimney.
If additional combustion air inlet openings are required, they
are not permitted to be closed or blocked.
CAUTION!
Simultaneous operation of the stove with ven-
tilation systems and/or exhaust hoods can cau-
se negative pressure to build up in the room
where the stove is installed, which can lead to
problems such as flue gas escaping from the
stove.
If the Luno will be operated as a room air de-
pendent stove, the negative pressure in the
room where the stove is installed is not permit-
ted to exceed the value of 4 Pascal.
When operated as a direct vent stove, the ne-
gative pressure in the room where the stove is
installed is not permitted to exceed the value of
8 Pascal. (the ventilation system designer speci-
fies the air pressure in Pascal units).
We recommend setting the ventilation system
to a maximum negative pressure of 4 Pascal.
NOTE!
In order that no oxygen is removed from the
room, we recommend the use of an extractor
hood which leads the air in an outward direc-
tion by means of a window contact switch, or to
guarantee that sufficient replacement air is able
to flow into the installation room.

Chimney Connection

The Luno stove has to be connected to a suitable chimney
with a minimum effective chimney height of 4.50 m. The „ef-
fective chimney height" is the distance between the flue gas
intake in the chimney and the top of the chimney pot.
The Luno can be connected to a chimney to which other
fireplace stoves are already connected. When operated as a
direct vent stove, the Luno must be connected to a separate
chimney.
The chimney cross section should correspond to the cross
section of the flue pipe. If the effective chimney height is too
low and/or the chimney cross section is too large or too small,
the draught capability of your stove can be impaired.
The Luno requires a 12 Pa output pressure (chimney draft). At
higher output pressures, the stove emissions increase, which
puts a high load on the stove and can lead to damage.
The Luno has a maximum permissible output pressure of 20
Pa at the flue gas intake duct. To limit the output pressure, a
butterfly valve (Fig. 4) or output pressure limiter can be used
(only possible with room air dependent operation).
After a soot fire occurs in the chimney, the flue gas path has to
be checked for tightness.
If these requirements cannot be complied with or if there are
any doubts concerning the suitability of the chimney, we re-
commend a chimney calculation according to EN 13384-1/2.

Flue Pipe Connection

CAUTION!
The flue pipe must be well sealed at the chim-
ney entrance and cannot project into the in-
ner cavity of the chimney; otherwise the flue
venting will be impaired (fig. 3).

fig. 3
The Luno has to be connected to the chimney with a flue pipe
with an inside diameter of 15 cm. Please ensure that all pipe
pieces are tightly fit at the connection junctions. We recom-
mend using elbow pipes with cleaning hatches.
CAUTION!
When operated as a direct vent stove, The flue
pipe has to be sealed at the flue pipe connec-
tion piece with Hase Sealing Paste. The flue
pipe connection to the chimney has to be gas
proof and sealed with a suitable sealing cord
and heat-resistant silicone.
Ensure that all flue tube supports and multiple
section flue tube connection points are sealed
with Hase sealing paste. (see Installation In-
structions)
