3.4 Energy efficiency
The energy efficiency of your stove is defined by the thermal energy input
over the thermal energy output (thermal output).
The iQ technology controls the optimal combustion air quantity for the
respective combustion situation.
This reduces emissions and heat loss through controlled discharge of the
exhaust gases into the chimney. (Increasing the efficiency).
To ensure your stove is as energy efficient as possible, the following points
must be observed/met:
► Observe amount of fuel added (avoid overload).
► Only use fuels specified in the operating instructions.
► Regular inspections/cleaning (see chapter "7 Maintenance").
► In the event of excessive chimney supply pressure, take
suitable measures (e.g. installing an airflow limiter).

4 Combustion air currents

4.1 Grate air, window air purge and rear wall air

Grate air :
A
Grate air is the air the fuel draws directly and typically from below
through the fire grate.
It supplies the ember area with oxygen and is commonly only
used during the lighting stage.
Window air purge :
B
Window air purge is the primary air supply for the flames and embers.
It is directed down from above along the firebox glass and reduces
soot particles on the glass.
This ensures effective and clean combustion of the wood gases.
Rear wall air :
C
Rear wall air flows from the back into the combustion chamber. It improves
the mixing with oxygen in the areas inside the combustion chamber the
window air purge does not reach.
The rear wall air reduces emissions and increases efficiency.

5 Setup, installation and assembly

5.1 Preparing for setup

The following conditions must be checked prior to setup:

Installation site:

▪ Check the load-bearing capacity of the installation site. Using a
floorplate can improve load distribution. When unsure, please contact
an expertor your architect.
▪ Verify the installation site is flat and level. Use a spirit level.
▪ Verify the safety distances (chapter "5.3 Safety distances for setup
and installation") can be met.
▪ Check the flooring material. If the flooring is flammable, a fireproof floor
plate must be installed in front of and next to the stove.
▪ Check if the stove can stand free. Installation in alcoves or additional
cladding are prohibited.
▪ Do not block vents or convection openings on the stove.
▪ Do not connect the iQ technology to a 230 Volt mains socket below the
stove. Only a 5 Volt USB connection is permitted below the stove.
Chimney:
▪ The chimney must be suitable for solid fuels and must comply with the
legal requirements in the respective country.
▪ The construction of the chimney and the effective chimney height
must meet the required minimum pressure for the fireplace stove.
▪ A chimney calculation as per EN 13384-1/2 can establish system
suitability.
▪ The temperature class of the flue gas installation (chimney and flue
pipe) must have a soot fire resistance of at least T400.
▪ The chimney cross section should correspond with the flue pipe
cross section. If the effective chimney height is too small and/or
the chimney cross section too large or too small, this can affect the
airflow pattern.
▪ The supply pressure (chimney airflow) for your fireplace model is listed
Fig. 2
in chapter "12.2 Technical data".
Operating your stove at a higher supply pressure than the max. supply
pressure specified will increase the emissions output.
Your stove will be heavily loaded and can become damaged.
▪ The max. supply pressure for the stove is 25 pascal.
A damper or a supply pressure limiter can help limit the
supply pressure (indirect vent operation only).
