4.7 OPERATION OF THE WATER HEAT EXCHANGER
WITH THE ambiente a4 H
2
O
The firebox door should only be operated in
mode A1. Tampering with the closing system
is not permissible.
The water heat exchanger is operated via
the lever behind the stove at the right-hand
side (cf. Fig. 11). This switches between the
lighting-up/adding more fuel position and the
combustion position. The lever does not have
an intermediate position.

Combustion position
(
Fig. 17 A
) The lever is right at the top. All the flue gas
will now be routed via the ambiente a4 H
2
O’s water heat exchanger. Wait for
the stove to heat up fully, the fuel to catch light and embers to form before
moving the lever to this position. That normally takes about 15-20 minutes.
Lighting or fresh fuel phase
(
Fig. 17 B
) The lever is right at the bottom.
The flue gas bypasses the ambiente a4 H
2
O’s heat exchanger. That allows the
chimney draught to develop as quickly and effectively as possible.
To keep the ambiente a4 H
2
O operating efficiently, be sure to add wood in time
to prevent the flue gas temperature dropping too low.
5. FUEL
The foundation “Wald in Not” (Forest in Danger) put it aptly in one of their
information brochures: “Wood does not cause any burden for nature. Wood
is stored energy from the sun. Sunlight, water and carbon dioxide are the
building blocks from which wood is created. Sunlight is chemically bonded
during the whole life of the tree. The sun’s energy is stored in lignin and
cellulose. This energy is set free again when the wood is burnt! You can find
out more information on the internet site www.wald-in-not.de.
Fireplaces may only be operated using fuels that correspond to the 1st
BlmSchV regulations. Only firewood (recommended residual moisture 20%
or less) or wood briquettes according to DIN 51731 are permissible for use
in stoves.
Incidentally: A measuring device for determining the moisture of firewood
does not cost very much and quickly pays off.
No other type of fuel may be used!
Therefore, it is not permissible to burn the following:
• Varnished or plastic-coated wood
• Chipboard or wood that has been treated with wood preservatives
• Wood originating from Europool palettes
• Waste, household rubbish and old clothes
• Paper, paper briquettes, cardboard
• Damp wood (residual moisture over 20%)
• Plastics / foam material of any sort
• Solid or liquid materials damaging to wood
