Intake from internal source

The combustion air can also be taken in from the installation room. The operator of the stove must ensure
without fail that sufficient combustion air is available (approx. 30 m³/h). Never exceed the maximum
ambient negative pressure of 4 Pa!

5.5 Flue with air intake system (AIS)

•
The AIS flue system is approved and certified for solid fuels.
•
The cross-section of the connection the combustion air intake connection from stove to chimney is equal
to at least the circular area of a 100 mm tube.
•
The air duct is insulated from the flue-gas duct. This means that no transmission of heat from flue gas
to combustion air occurs.
•
The cross-sectional area of the air intake is at least equal to the circular area of a 100 mm tube.
•
There must be no contact between flue gas and air intake at the point of entry to the chimney or along
its length.

5.6 Non-dependence on ambient air

The tightness of the stove conforms to German requirements for solid fuel combustion appliances non-
dependent on ambient air. The approval allows use in passive houses, low-energy houses and rooms with
controlled ventilation and external combustion air intake.
•
The test was carried out by TÜV Southern Germany.
•
Approval has been applied for to the DIBt (Deutsches Institut für Bautechnik).
•
The pellet stove's installation must be inspected by the regional master chimney sweep before being
used for the first time (valid certificate of chimney sweeping).

5.7 Backflow system

ATTENTION: It should be ensured that the return temperature at the intake connection to the heat
exchanger does not fall below 50 °C during heating mode. Undercutting this temperature results in corrosion
and soot formation and thereby, destruction of the heat exchanger.
To ensure safe operation the stove is to be properly connected to a reliable heat take-out facility (buffer
tank). The requisite water quality is stipulated in Ö NORM H 5195 and is to be observed.
Without a regulation return riser the guarantee is invalidated!
