3.4 RATING PLATE
The rating plate contains technical data and information. The rating plate
must not be removed, as it is proof that the stove has been tested and it is
needed for acceptance and for the annual inspections by the chimney sweep.

4. COMBUSTION
4.1 LIGHTING THE STOVE FOR THE FIRST TIME
The ambiente a1/a2/a3/a4/a5/a7/a8 stove must be assembled and installed
by a specialist contractor. Commissioning must always be carried out by an
expert from the installation firm. The owner / operator of the system must be
handed a certificate stating that the system has been properly installed and
all control and safety components have been correctly set and are operating
correctly (see sample in section „9.1 Commissioning report for ambiente
a1/a2/a3/a4/a5/a7/a8“ on page 46).
Only a moderate fire should be lit when using the stove for the first time. That
way, you avoid cracking the fire chamber lining (the lining may still contain
residual moisture at commissioning). Slowly increase the heat output the
next 3 to 5 times the stove is lit, up to about 30% above the nominal output,
to allow the anti-corrosion coating on the surfaces to burn in correctly. The
wood consumption will be approx. 2.5kg/h for a typical combustion period
of about 45 minutes. That corresponds to 1.8 kg wood per combustion
cycle, though the actual combustion duration can vary according to local
conditions. The colour of the coating may mellow slightly during this pro-
cess. Do not place any objects on the ambiente a1/a2/a3/a4/a5/a7/a8 and
do not touch the stove. 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.
