Lighting the stove for the rst time
Discolouration of walls, ceilings and grates
The walls, ceilings and grates may show some discolouration after lighting your hearth. This is caused
by the dust particles that burn in the convection cover. This is a natural process for which WANDERS
cannot be held responsible. To minimize discolouring we refer to the advice given for atmospheric
hearths. Your installer can give you more information about this.
When you light the Square Basic Basic for the rst time, the hearth must still ‘anneal’ and temper itself. The
unit has a heat resistant lacquer which must burn in the stove at temperatures above 400 °Celsius. This will
happen during the rst few times of lighting the stove and temperatures rise to 600 °C. Though this may give
an unpleasant smell, it is otherwise harmless. It is advisable to keep the stove burning with limited fuel for at
least 6 hours when lighting the stove for the rst 4 or 5 times. Air the room well when the stove is burning.
Make sure that any cooking hood is not turned on when the stove is burning; a cooking hood extracts the
combustion air that the stove needs.
Some deposit may form on the glass panes of the stove when you ‘anneal’ your hearth. You can easily remove
this deposit with a damp cloth after the stove has cooled down. You can also use some cleansing agent for
ceramic rings. Please make sure you do not leave any nger marks on the clean glass. Finger marks burn into
the glass and cannot be removed later.
Newly-built house or recently renovated?
It is advisable to wait six weeks before lighting the stove in a newly-built house that has recently
been completed, or in a space that has recently been renovated drastically. The walls and ceilings still
contain gases, softeners and moisture from plasterwork or paint. The warm air-streams may discolour
the dust particles in the space which may stick to walls and ceilings. Even the moisture in the walls and
ceilings will become warm and may cause yellow stains.

The Square Basic Basic only burns on wood. Do not put more than 3 kg of fuel in the stove at the time. Always
use clean and cut logs, which have suciently dried. Please see the above list for drying times. Wet wood does
not burn well and gives heavy smoke emission. It may blacken the glass pane of your stove with soot and build
up smut in the ue pipe. This may increase the risk of chimney re.
Fresh, moist wood contains about 50% moisture. Cleaved wood still contains 20% moisture after drying it for
a year and moisture percentage will be decreased to 12 to 15% after drying it for two years. Dry wood gives nice
ames and little or no smoke, and the re will crackle when burning. Wet wood makes a hissing sound, gives
much smoke and only small ames which will considerably dampen the pleasure of burning your stove and the
heat output.
Do not put any paran-containing logs in your stove. When the door is closed, the high heat will
melt the paran from the logs too quickly. The polluted ue gasses which consequently develop will
deposit on and burn in the glass of your stove and cannot be removed later.
