easily using a slightly moist cloth once the stove has cooled. If necessary, use a special cleaning agent designed
for ceramic hobs. Do not touch the clean glass with your fingers. Fingerprints burn into the glass and can never
be removed.
After the first couple of times using the stove, the cord in the door will expand to follow the contours of the stove.
HI2 Insides
The HI2 insides were specially developed for WFS and, without giving away too much of our
secret recipe, comprise a mix of special concrete with vermiculite. The heat-reflective action
of the vermiculite generates heat build-up in the combustion chamber while the rest of the
material stores the heat.
Once combustion is well under way, you will see a perfect fire – clean, eco-friendly combustion
with a high heat yield.
The fire bricks, weighing in at some 30 kg, initially require thorough heating. The heat in the combustion chamber
is key to ensuring the stove works properly. We therefore advise getting the fire going with thinner, more easily
combustible wood. Leave the doors slightly ajar for a quarter of an hour so the fire quickly starts to burn fiercely.
If you then ensure a red-hot bed of ash for further combustion, this will create decent flames and radiant heat that
you can enjoy for the rest of the evening, while occasionally adding fresh wood.
The heat is stored by the fire bricks - known as accumulation - so any fresh logs ignite quickly. This accumulating
action means that the stove continues to give off heat for a long time after the fire is extinguished.
The HI2 insides are made using water, so the moisture will have to be heated out of the fire bricks during the first
few sessions.
Our advice is to get a really good fire going for the first few hours. At that point, the fire will probably not look like
it did in the showroom, but the appearance will improve rapidly after the first couple of fires.
After installation, it is essential that you first allow your home to dry thoroughly. Inadequately
dried walls retain soot and other substances that are released by the stove during use. The risk
of cracks in the plaster is also highest at that point.
Fuel
The Smart only burns on wood. Never place more than 2 kg (Smart 60) and 3 kg (Smart 75) of fuel in the fire at
once. Always use clean, harvested timber that has been allowed to dry thoroughly. See the table below for drying
times. Moist wood burns poorly and generates far too much smoke. This can cover the glass of your stove with
black soot. Soot particles (creosote) also stick in your flue, which increases the risk of a chimney fire.
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 flames
and little or no smoke, and the fire will crackle when burning. Wet wood makes a hissing sound, gives much smoke
and only small flames which will considerably dampen the pleasure of burning your stove and the heat output.
