• Never empty the ash pan when the Aduro H5 is warm. Embers may still be found in the ash pan
for up to 24 hours after the fire has gone out. Please wait to empty the ash pan until you are sure
that there are no embers in the ash.
• The door should be kept closed while the Aduro H5 is in use. While lighting the fire, the door can
stand ajar for the first few minutes.
• The pellet function stops if the door is opened.
• When putting logs in a hot stove, you must always open the primary air intake and make sure that
the wood ignites within 2-3 minutes. If the wood does not ignite, add some ignition products and
ignite them manually.
• In the event of a chimney fire: Close all the dampers on the Aduro H5 and call the fire-fighting
service.
3.1 Damper
The stove is equipped with a damper under the door, which regulates the combustion air: primary,
secondary, and tertiary air supply. The primary air is used at the beginning to get the fire going, the
secondary air keeps the fire burning evenly, and the tertiary air ensures that flue gasses are burned. You
must always add secondary and tertiary air, while firing the stove. According to our experiences regarding
the use of the pellet function, we recommend that the damper is always completely closed to achieve the
optimum combustion of the pellets.
The damper allows you to adjust the Aduro H5 according to the chimney draft and the heat output, you
require. The longer the damper is pulled out, the more air is added and the more powerful the combustion.
The illustration below shows the stove seen from the front with the dampers indicated. Use edge of door to
read position of inlet air:
3.1.1 Secondary air supply
In normal circumstances, the Aduro H5 should be working with this damper between 60 % and 100 % open
(the damper is placed between position 2 and 3). You should never close the air intake so far that the flames
are extinguished. There should always be visible flames in order to achieve clean and efficient combustion.
A too low supply of air can lead to bad combustion, high emissions and a bad efficiency.
If you wish to fire the stove with the lowest effect possible – around 3 kW – you must close the secondary air
supply almost completely 45 minutes after the wood has been put in. At this point there are only few flames
and the stove can burn clean by using the tertiary air from behind in the stove.
1: Fully open primary and tertiary air inlet. This position can be
maintained with the Aduro key, which must be placed in the
two holes.
2: Closed primary air inlet, fully open tertiary air inlet.
3: Closed primary and tertiary air inlet (used when burning
wood pellets).
The secondary air inlet is regulated above the front door. This
air inlet should be closed, when only burning pellets.
