Primary Damper; Aduro-Tronic - ADURO H1 Manual De Instrucciones

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.

3.7 Primary damper

When you add a new log, the primary air intake/damper should be opened until the fire is burning properly. In
order to utilize the fuel to the fullest extent, the embers should have burnt for so long that it is necessary to
open the primary air intake for approx. 2 minutes to get the new log to burn.
In order to reduce the risk of ash falling from the stove when the door is opened to add more fuel, it is a good
idea to open the primary air intake/damper for approx. 1 minute before the door is opened. This increases
the draught through the stove and reduces the risk that ash will drop on the floor.
Please note: if you overload the Aduro H1 and burn more than approx. 3.1 kg wood/hour, there is a risk that
the lacquered surface of the stove will become discoloured and eventually fall off. The stove can be
resurfaced, but this is not covered by the manufacturer's guarantee. In the same way, any other damage to
the stove caused by overloading will not be covered by the guarantee.

3.8 Aduro-tronic

The patent-applied Aduro-tronic is designed to operate the stove for you. All you
have to do is put dry wood in the stove, and activate the control system - Aduro-
tronic does the rest, leaving you to enjoy the flames and the benefits of efficient
combustion. Aduro-tronic is a manually operated mechanical start-up device,
which works without the use of electricity.
Please note: Use of dry wood of the right size is important to achieve optimum
combustion.
3.8.1 How to operate Aduro-tronic
When lighting
When lighting a fire in the Aduro H1 for the first time, the maximum amount
of primary air will be needed to light the fire. For that reason, the primary
damper can be kept "forcibly open". This is done by pulling the primary
damper forward as far as possible and then fixing it with the Aduro Key (see
illustration). When the stove is warm and a layer of embers has been created
on the bottom of the combustion chamber, the Aduro-tronic can be set to the
automatic position, i.e. the Aduro Key can be removed.
Alternatively, you can leave the door ajar the first minutes during lighting the
fire (without the key).
When stoking
Each time fresh wood is put in the stove, a precise amount of primary air will
be allowed in for the first few minutes. What's more important is that the
primary air is not allowed in for too long. This is to ensure optimum
combustion. The Aduro-tronic control will ensure intake of primary air at the
right tempo. The automatic is activated by pulling the primary damper out
each time fresh wood is put in the stove. The automatic closes then the
primary air gradually.
Regulation of the Aduro-tronic control
The control is pre-set to allow primary air intake for the first 5 minutes. This setting has been used during
testing at the Danish Technological Institute using 'standard' sized logs and with maximum moisture content
of 18%. Standard size logs are approx. 30 cm long and 10 x 10 cm in thickness. A standard chimney was
also used for testing. In practice, such circumstances can differ, which is why the Aduro-tronic control can be
adjusted to your circumstances. If you want a slower intake of primary air: (e.g. for a slower flue draught,
larger sized wood or for longer intervals between stoking) Adjust the screw on the front of the control level
using a small allen key to slow closure rate. If the screw is turned to the right closing time is increased and if
turned to the left closing time is reduced. The Aduro-tronic must be closed within 6 minutes.
