approx. 7-9 cm. Let the fire burn and let the stove cool down to room temperature before the next lighting.
3. The third stoking
Repeat the second stoking, but use more wood this time. Set the temperature level to level 3. Let the
fire burn and allow the stove to cool down after the fire has died out.
Restoking:
Follow the general instructions, see the sections “Lighting the stove” and “Stoking”.
Lighting Up
A successful combustion process requires that the wood is lit in the right way. A cold stove and a cold
chimney challenge the combustion process. Be careful to make a good lighting with suitably dry wood,
using kindling and lighting the fire in the top layers of kindling.
Open the door. Place two pieces of wood (5-8 cm in diameter) horizontally in the
bottom of the combustion compartment. Place 5-8 pieces of kindling randomly
on top. Place two fire-lighters in between the top layers of kindling. Light up the
fire-lighters and close the stove door. Select the desired room temperature level.
When the door of the stove is opened the IHS system is activated. If lighting up does not occur within
15 minutes, the system will automatically go back to standby and the dampers will be closed.
If the flue gases do not reach a high enough temperature for kindling or firing, IHS Smart Control
TM
and
the wireless room temperature sensor emit a stoking alarm, even if there is still unburned wood and
flames in the combustion chamber. The stoking alarm is emitted to make you aware that the fire needs
more energy. Restoking with small pieces of kindling wood can often provide a more rapid and sufficient
temperature rise.
HWAM Autopilot IHS
TM
closes all three air dampers when the stove is in standby mode. This prevents
hot air from the room to enter the chimney (heat loss). This might on the other hand result in a very
cold chimney when the stove is lit. In certain cases it is necessary to assist the draught in the chimney
by burning a couple of newspaper pages on top of the wood ready to be lit. Read more on www.hwam.
com about the function of the chimney.
Important!
The door must not be opened when lighting up. It must always be closed when the stove is in use. Oth
-
erwise the stove’s intelligent control system does not function. The door should only be opened when
lighting up, when restoking, and when cleaning the stove. Never leave a stove before there are lasting
flames in the wood after firing!
The Thermostat Function
The HWAM Autopilot IHS
TM
will in general have an environmentally friendly combustion and adapt to
the desired room temperature. The thermostat function is designed as a radiator valve. The user enters
a desired heat level, which suits the room in which the stove is installed. When the thermostat is set at
a heat level, the control function will adapt to this temperature.
• If the room temperature is lower than the desired heat level, the control function increases the flue
gas temperature in order to increase the heat radiation from the stove.
• If the room temperature is higher than the desired heat level, the control function decreases the flue
gas temperature, thereby giving the layer of embers as long a life as possible before re-stoking. This will
reduce the heat radiation from the stove and facilitate re-stoking without having to light up the fire
anew. If the room temperature drops below the desired level, the ember phase will be shortened, and
the system will activate a re-stoking alarm. The system will signal that a re-stoking is due at the flue gas
