it will produce beautiful dynamic yellow flames. If necessary, the flames’ effect is regulated
steplessly with the regulator rod.
Note! At cold start, if fuel has been left long in the hearth, a safety function prevents it from
lighting immediately. In such a case the hearth can be started by holding the lighter lit for
about 10 seconds while its flame barely touches the burner matrix. If the hearth does not start,
add new fuel according to Section 4.2.2, keeping in mind that the burner in this case will
absorb less than 2 litres.
Warning! This procedure may increase the wear on the burner and thus reduce its lifetime.
Vauni recommends that tanking be done not long before the hearth is used.
5. If the hearth goes out immediately after lighting – repeat the lighting procedure in point 4
above.
6. If possible, do not run the hearth until it goes out by itself. The ceramic wool in the burner
retains its performance best if kept constantly moist by the bio-ethanol, even when not in use.
Note 1! On the first occasions of firing, some smell may arise – this is quite normal. The smell
decreases gradually after a number of firings.
Note 2! A clicking sound may occur during firing, at the start or when the fuel level is low and
the flames are smaller. This is quite normal.
4.2 Fuel
The Divider is optimized for, and must only be used with, liquid denatured ethanol – whose
burning produces only carbon dioxide and water vapour, the same components as in the air we
breathe out.
Warning! The fuel must not be preheated.
4.2.1 Recommended fuel quality
For Vauni Divider we recommend Vauni ECO-FLAME which is the market’s most optimal bio-
ethanol fuel for use in chimney-free hearths and inserts. This product gives natural, smoke- and
soot-free flames with a neutral aroma, and can be ordered at www.vauni.com. In cases where
ECO-FLAME is not available, only liquid denatured ethanol (bio-ethanol) must be used, which is
sold under various trade names at building-supply stores, DIY-stores, petrol stations and large
markets. (Applies for Sweden – for other markets consult your distributor)
Denatured ethanol is an inflammable liquid, and therefore must be handled with great care – in
Sweden according to the prescriptions and general advice for handling inflammable liquids
(National Inspectorate of Explosives and Flammables, SÄIFS 2000:2). Handling of larger amounts
than 100 litres requires a permit for handling of inflammable goods (SÄIFS 1995:3). For more
