Controlling combustion air
The appliance has various features for air control; see
following figure.
The primary air slide controls the air flow under the
grille (1).
The secondary air slide controls the air flow for the
glass (airwash-system) and air supply via the vents in
the back wall (2).
The back wall has permanent vents (3) below the
baffle plate that allow for post-combustion.
Advice
Never burn wood with an open door.
Regularly burn wood with intense roaring fires.
If you frequently have low intensity fires, tar
and creosote may be deposited in the chimney
. Tar and creosote are highly combustible
substances. Thicker layers of these
substances may catch fire if the temperature in
the chimney increases suddenly. By allowing
the fire to burn very intensely regularly, layers
of tar and creosote will disappear.
Low intensity fires also cause tar deposits on
Subject to change because of technical improvements
the stove window and door.
When the outside temperature is not very low,
it is better to burn wood intensely for a few
hours instead of having a low intensity fire for a
long period of time.
Control the air supply with the secondary air inlet.
The secondary air inlet not only supplies air to
the fire but to the glass as well, so that it does
not quickly become dirty.
Open the primary air inlet for the time being if the air
supply by the secondary air inlet is inadequate or if
you want to fan the fire.
It is better to add a small amount of logs regularly
than to add many logs at the same time.
Extinguishing the fire
Do not add fuel and just let the fire go out. If a fire is
damped down by reducing the air supply, harmful
substances will be released. For this reason, the fire
should be allowed to go out naturally. Keep an eye on
the fire until it has gone out. All air inlets can be closed
once the fire has died completely.
Removing ashes
After the wood has been burnt, a relatively small
amount of ashes is left over. This bed of ashes is a
good insulating layer for the stove base plate and
improves combustion. It is good to leave a thin layer
of ashes on the stove base plate.
The flow of air through the fire plate must not be
obstructed, however, and no ash may be allowed to
accumulate behind a cast-iron inner plate. Remove
the excess ash regularly.
Fog and mist
Fog and mist hinder the flow of flue gases through the
flue. Smoke can blow back and cause a stench. If it is
not strictly necessary, it is better not to use the stove
in foggy and misty weather.
Solving problems
Refer to the appendix "Diagnostic diagram" to resolve
any problems in using the stove.
