Where it is necessary to have a horizontal length of
pipe, there must be a minimum positive gradient of
3% along its length.
It is forbidden to run flue pipe in a horizontal plain
or in a reverse gradient.
It is forbidden to install the smoke outlet at pave-
ment level, on public streets, car-parks or anywhere
that might cause annoyance to people and/or ani-
mals.
The flue must be installed with the outlet above roof
level.
IMPORTANT: All sections of the flue pipe must be
accessible for inspection, and allow for internal
cleaning, removal or substitution.
Do not place nets or grilles over the flue outlet.
When they become dirty they will obstruct the out-
let and cause poor combustion, and the stove may
be blocked with soot.

COMBUSTION AIR
The process of combustion requires oxygen, and
therefore air. When in operation, the stove draws
air from the room in which it is installed; poor com-
bustion may therefore result if the room is insuffi-
ciently ventilated.
To resolve this problem, a suitable vent hole must
be provided to allow a permanent supply of fresh air
from the outside. The cross-section of the vent
must be 6 cm² for each kW of energy consumed at
maximum input 67cm
The ventilation hole must have a cross-sectional
area of 67 cm² if a flue draught stabiliser is fitted.
If no flue draught stabiliser is fitted the ventilation
requirement is 34cm².
If the stove is located in a room containing another
appliance cooker hood or extractor fan, it is essen-
tial to provide ventilation equivalent to the sum of
the air requirement for all appliances.
The vent must not be placed directly beside the
appliance in order to avoid drawing in air that is too
cold: at certain times of the year when the appli-
ance is very cold, the stove may be locked out
when you first attempt to light it. If this occurs, the
situation should be considered absolutely normal,
and you can unlock the stove using the switch #4
located on the control panel. Then switch on again.
SAFETY AND CORRECT USE OF THE APPLI-
ANCE
Before switching on for the first time, read the fol-
lowing safety instructions.
1. Some parts of the stove become hot (door,
glass, flue, etc.), and contact with these parts
may cause burns.
2. Do not place combustible or inflammable
materials beside the stove, and never at less
than 1 metre.
3. Do not store bags of pellets close to the stove.
4. Your stove burns pellets only - it is not an incin-
erator. It is forbidden to burn other materials or
household waste as fuel.
5. When loading pellets into the tank, avoid pour
ing sawdust along with them. Failure to follow
this instruction may make the appliance unsafe,
and void all warranties.
