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

Flue Pipe Connection

The Ottawa 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. 9).

10. Butterfl y Valve
The butterfl y valve (Fig. 10/1) 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. 10) is open
before opening the fi re box door during the
burning phase.

11. 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 Ottawa.
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
- any fl ammable fl uids (including methanol
and ethanol) as well as any fuel pastes
or gels
is not permitted.
ENVIRONMENT!
Combustion of the materials listed above not
only gives off unpleasant odours, but also
generates emissions that damage the environ-
ment and are harmful to health.
Combustion of non-permitted fuels constitutes
a violation of the German Federal Immission
Control Act.
Improper fuels and their combustion residues
can be detrimental to the functioning and ser-
vice life of the stove and chimney – use of such
fuels voids both the warranty and guarantee.
