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 
temperature of 180° C, and at 100° C the system will enter standby mode and all dampers will close.

•  Should the room temperature be much lower than the desired heat level, the control function increases 

the flue gas temperature. If a satisfactory increase in temperature does not occur, the control will activate 
a re-stoking alarm, since it expects that more wood is needed to increase the heat level in the room.

•  If the room temperature after a new re-stoking still does not reach the desired level, the water content 

in the firewood may be too high or the draught in the chimney too weak. The IHS system always strives 
for a sufficiently high flue gas temperature to ensure an environmentally friendly combustion.

Stoking

When alarm for re-stoking sounds the stove is ready for re-stoking. The alarm for re-stoking will come 
via the room temperature sensor or the acquired remote control. The app IHS Smart Control

TM

 will 

also come with a notification that it is time for re-stoking if the app is opened. For more information on 
the app, see separate manual.

The amount of woo that is used for re-stoking should be adjusted based on the current heat demand. 

Small amount of wood 

Medium amount of wood  

Large amount of wood 

(700 - 1200 g) 

(1000 - 1800 g) 

(1600 - 2300 g)

In terms of combustion technique, you should always stoke the stove with at least two pieces of wood 
at a time even if you only use a small amount of wood. You can also choose not to restoke.  After a while 
the stove will then automatically go into hibernation.

Important!
Never leave a stove before there are lasting flames in the wood after re-stoking! 
During combustion, the outer surfaces of the stove will become hot, and due care must 
therefore be shown.

Fuelling with coal, wood briquettes or pet coke

The stove is not approved to use coal or pet coke as a fuel. However, wood briquettes can be used to 
fuel the fire and should be placed on the embers produced by the burned wood. 

Be aware that using fuels other than wood, will cause soot to form on the glass pane.

Operating the heat compartment damper

There is a damper at the back of the stove between the top plate and the heat compartment that opens 
and closes the flow of convection air in the heat compartment. The supply of convection air can be opened 
by moving the damper to the left and closed by moving the damper to the right. 
To store heat in the heat storage stones in the heat storage compartment as quickly as possible, it is 
recommended that the convection vent be kept closed while the fire is lit.
With the convection vent closed, the heat storage compartment retains the heat stored in the heat stor-
age stones for the longest possible duration. If the vent is opened, the heat stored in the stones in the 
heat storage compartment will be released into the room as quickly as possible.
