Commissioning must not take place until all the necessary components have
been connected up, all necessary safety devices have been integrated and
are operational, the water heat exchanger has been filled and the system
has been vented. It is not permissible to operate the system without water,
when only partly filled or with safety devices that are not operational. It
may be necessary to vent the water heat exchanger several times at com-
missioning (refer to
Figure 12b/12c
, section „2.9.1 ambiente a4 H

O pipe
connections“ on page 21).
The operator must also be given detailed instructions on the operation,
functioning and maintenance of the entire system including all additional
components. The measures necessary to keep the system operating safely
must also be explained to the operator. Operator instruction must be docu-
mented in the commissioning record. The Installation and Operating Manual
should be kept in an easily accessible place near the ambiente a4 H

O.
Before commissioning it is important to check whether any objects are still
inside the fire chamber or in the ash pan. If so, remove them.
The stove is supplied with a ceramic fibre mat 3-5 mm thick on top of the
baffle plate of the fire chamber lining. This is needed to soak up any con-
densate occurring the first three times the stove is lit. Before lighting the
stove, check that the mat is lying snugly on top of the fireclay baffle plate. If
the mat is not in position, condensate can drip on to the fire chamber lining,
leaving permanent stains. The fibre mat can be removed after the stove has
been lit 2 or 3 times. Also, dirty condensate may leak from the bottom of
the fire chamber and may soil or damage the floor underneath the stove. An
absorbent material should therefore be placed under the stove the first few
times it is used, until there is no more condensate leakage.
Only a moderate fire should be lit when using the stove for the first time
(approx. 1.5 kg/h) to avoid cracking the fire chamber lining. There may still
be some residual moisture in the lining when the stove is lit for the first time.
That moisture can escape, e.g. via the air connection box and the rear wall,
the first few times the stove is lit. It is important to ensure that the fibre mat
is correctly positioned on top of the baffle plate. That way, the condensate will
be absorbed before it drips on to the fireclay and possibly causes stains. The
air inlet should be open during this time.
Slowly increase the heat output the next 3 to 5 times the stove is lit, up to
about 20% above the nominal output (wood consumption approx. 2.6 kg/h)
to allow the anti-corrosion coating on the surface of the stove to burn in cor-
rectly. An unpleasant odour, which is harmless to health, may be given off
during this process (sometimes accompanied by a small amount of smoke).
It is therefore important to ensure that the room is well ventilated during
the burning-in process. Open all the doors and windows to let fresh air in.
Please note that slight expansion or contraction noises may be heard as the
stove heats up or cools down. Such noises occur as the material expands at
high temperatures, and are not a cause for concern.
4.2 CONTROLLING THE COMBUSTION AIR SUPPLY
The combustion air supply is infinitely adjustable with the aid of the air
adjustment lever, which is located below the door (see
Fig. 16
). The lever
must be operated with the firebox door closed.
Air supply open: When lighting the stove or when adding more wood, move
the lever all the way to the right. That delivers the maximum combustion air
