Chimney; Flue Pipe Connection; Butterfl Y Valve; The Right Fuel - HASE Luno Mode D'emploi

6.

Chimney

The Luno has to be connected to a suitable chimney with
a minimum effective chimney height of 4.50 m. It can be
connected to a chimney to which other fi replaces are already
connected. The chimney cross section should correspond to
the fl ue pipe cross section. 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 stove requires a 11 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 stove has a maximum permissible output
pressure of 35 Pa. To limit the output pressure, a butterfl y
valve (Fig. 4) or output pressure limiter can be used.

Flue Pipe Connection

The Luno has to be connected to the chimney with a fl ue
pipe with an inside diameter of 15 cm. Please ensure that
all pipe pieces are tightly fi t at the connection junctions. We
recommend using elbow pipes with cleaning hatches.
CAUTION!
The fl ue pipe must be well sealed at the
chimney entrance and cannot project into the
inner cavity of the chimney; otherwise the fl ue
venting will be impaired (Fig. 3).

8. Butterfl y Valve
The butterfl y valve (Fig. 4/1) is an optional control element. It
is fi tted in the fl ue pipe and used to regulate the fl ue gas fl ow,
and can thus slow down the burning-off process. When the
handle's position is diagonal to the fl ue pipe, the fl ue gas fl ow
rate is turned to minimum. We strongly recommend installing
a butterfl y valve to reduce the output pressure. Please comply
with the country-specifi c legal regulations.

NOTE!
Make sure butterfl y valve (Fig. 4) is open
before opening the fi re box door during the
burning phase.

The Right Fuel

Only fuels which generate low quantities of smoke may be
burned in stoves. Only fuel in the form of natural, untreated
wood logs or bricks, including the adherent bark, can be used
for the Luno.
For the most attractive stove fi re, use beech wood logs. If
other types of wood are used, such as oak, birch, pine or
larch, we recommend adding beech wood for picturesque
dancing fl ames. Brushwood and small pieces of wood are
good kindling materials.
Highly resinous coniferous wood (e.g. spruce, pine, fi r) tends
to emit fl ying sparks and leaves behind a fi ne layer of fl ue ash
that can swirl up when the fi re box door is opened.
The fi rewood should be stored for at least two years to achie-
ve the required maximum residual moisture content of 20%.
CAUTION!
If the wood used as fuel is too moist, water
vapour can condense and damage the stove. In
1
addition, it will reduce the thermal output.
CAUTION!
Burning, e.g.:
- damp or moist wood(residual moisture
content over 20%),
- varnished, laminated, treated, or plastic-
coated wood,
- wood treated with wood preservatives,
- household waste,
- paper briquettes (contains pollutants such
as cadmium, lead, zinc), or
