We congratulate you on the purchase of your stove.
This manual will inform you about the best way of using the stove and the art of keeping a perfect fire.
Before using the stove, carefully read the text about breaking in the stove. These heating instructions apply to the Boxer Plus.
They are merely intended as a guideline as your stove will behave differently according to the place where it is installed, simply
because the conditions are different. The flue, the weather, the quality of the wood used and the climate conditions in the
house determine your stove’s burning behaviour. In time, you will develop your own directions for use, based on these heating
instructions.
Three basic rules
1. Use dry and clean wood.
The stove is designed for burning so-called ‘stackable fuels’: wood and briquettes. We assume you will be using dry fuels
only. So, this also holds for the kindling paper and cardboard. Wet fuel costs more energy, leaves moisture on the glass
and soils the flue.
2. Do not dampen the stove excessively.
Allow the stove sufficient time to warm up (at this stage, do not leave the stove unattended) and do not reduce the fire too
quickly. Bear this rule in mind: you must not dampen a stove until it has reached its proper temperature.
3. Always ensure there is enough fresh air.
In houses today, cracks and chinks have usually been sealed. Opening a small grate or cantilever window will ensure
sufficient fresh air. Or use the fresh air supply connected to your stove if provided with such a control feature.
The main thing when making a fire is that both the flue and the stove reach the proper temperature.
The fine heat from wood
You have purchased a wood stove. In many respects, wood as a fuel is a
ideal choice. But what is wood exactly? Under the influence of sunlight, a tree
builds up wood cells from CO2 (carbon dioxide), water and energy. In its growth
process, the tree takes CO2 from the air and gives off oxygen in return. That’s
why a walk in the woods is so healthy. Also in terms of the environment, wood
is an ideal fuel. If it is simply left to rot, the same amount of CO2 is released as
when it is burned. In environmental terms, we then say that wood is
‘CO2 -neutral’.
Only dry wood is firewood suitable for a stove.
Not all wood qualifies as stove wood. Good burning is achieved by using wood that has been
seasoned (wind-dried) for at least eighteen months. That is to say: preferably chopped wood,
stored under a shelter that protects it from the rain, so that its moisture can gradually evaporate.
Dry wood does not sizzle in the fire and does not soot the glass.
Wood thickness
When building your fire, preferably use wood thicknesses in the order shown:
1. Kindling wood
2. Thicker wood
3. Solid log
(abt. 2x2x30cm)
(abt. 4x4x30cm)
(abt. 7x7x30cm)
The power of fire
There is hardly anything that can resist a really hot fire. Your stove, too, could be damaged by overheating. To prevent this
from happening, you must not burn more than 4 kg of dry wood at a time in your Boxer Plus. 4 kg equals roughly 4 solid oak-
wood logs having a 15% residual moisture content. The construction and materials used have been chosen so as to be able to
control and resist a responsible fire. So, manage your fire judiciously.
