Ventilation; Use Of Stove - RAIS/attika VISIO 3-1 NS Manuel D'utilisateur

English
By setting the interval between position 1 and 2 (see next section) ensures optimum
utilisation of the energy content of the wood, as there is oxygen for combustion and
for the burning of the pyrolysis gases. When the flames are a clear yellow the damper
has been set correctly. Finding the correct position comes with time after regular use of
the stove.
We do not recommend to turn it down completely, because it feels too hot. Too little
air supply gives poor combustion, which can cause high and dangerous flue gases,
emissions and poor efficiency. This results in dark smoke emanating from the chimney,
and the calorific value of the wood not used to its fullest.

Ventilation

There must not be an extraction/range hood (kitchen) in the same room as the stove as
this may cause the oven to emit fumes into the room.
The stove requires a permanent and adequate air supply to operate safely and efficient-
ly. There can be fitted a permanent air supply vent to the room to the stove's combus-
tion air (see section on Air System).
This air vent should not be shut off or sealed under any circumstances.
Use of the stove
Adjustment of the air dampers - the damper has 3 settings
See diagrams at the front of the manual.
Position 1
Push the lever fully to the left.
The damper is closed; there is a minimal air intake.
This option should be avoided during normal operation.
See warning note after next section.
Position 2
Pull the lever to the right up to the first notch (center position).
This position gives only secondary air.
During ordinary stoking the lever is set between position 1 and 2.
When the flames are clear and yellow, the damper is set correctly - resulting in a slow /
optimal burning.
Position 3
Pull the lever to the right.
The damper is fully open and provides full ignition air (primary) and full secondary air.
This position is for the lighting stage and refuelling and is not used during normal
operation.
