4.1 INITIAL COMMISSIONING
The stove must be assembled and installed by a specialist contractor. The
initial commissioning must only be executed by an expert employee of the
installation company. A certificate confirming proper installation and proper
adjustment / function of all control components and safety components
must be given to the owner / operator of the system (see „9.1 Commission-
ing protocol ambiente a1/a2/a3/a4/a5/a6/a7/a8“ on page 53).
When first putting your appliance into service, only start a moderate fire.
This enables you to avoid cracks in the firebox lining (which may still contain
residual humidity before the first firing). Slowly increase the heating power
to about 30% above nominal heat output by setting the fire 3 to 5 times to
give the corrosion coating applied to the surfaces time to 'burn in' properly
During this process, the paint can become slightly soft, do not place any
objects on the stove and do not touch the appliance. During this burning-in
process, an unpleasant yet harmless odour (sometimes accompanied by
the build-up of smoke) may be given off. 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.

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 commissioning.
The operator must also be given detailed instructions on the operation,
functioning and maintenance of the entire system including all additional
components. In addition, the measures for maintaining safe operation of the
system must be communicated to the owner. Briefing must be documented
in the commissioning protocol (see point 9 Commissioning protocol) The
installation and operating instructions must always be kept in the vicinity of
the ambiente a4 H

O where they can be easily accessed.
Before commissioning it is important to check whether any objects are still
inside the firebox 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
deflector plate of the firebox lining. This is needed to soak up any conden-
sate occurring the first three times the stove is lit. Before lighting the stove,
check that the mat is lying snugly on top of the chamotte deflector plate.
If the mat is not in position, condensate can drip on to the firebox 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 firebox 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.
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.
