In the event of a power failure, the chimney has to ensure the safe discharge
of the flue gases from the appliance. Consequently it performs an important
safety function and therefore several points are to be observed:
•
It is obligatory to provide a connection to a chimney that is non-susceptible
to moisture and suitable for solid fuels.
•
The chimney has to conform to the specifications given on the type plate and
in the user manual of the stove.
•
Prior to installation it is necessary to perform a calculation of the chimney as
regards its dimensions.
•
If the chimney draught is too high (>16 Pa) we recommend installing a damper
(draught regulator)
•
Always connect the appliance to a separate chimney; no other heating appli-
ances should be connected to the same flue or chimney system.
•
The flue pipe is to be connected to the chimney in compliance with the re-
quirements of the Building Regulations. For further questions please consult
your local chimney sweep.
•
Make sure that all flue pipes are leak-proof. Your local chimney sweep will
be happy to give advice

Suitable fuels
WOOD PELLETS
It is imperative that only wood pellets conforming to the Austrian standards
ÖNORM M7135 or DIN Plus are used. Diameter 6 mm, length max. 30 mm.
Storage of wood pellets
Pellets are supplied with a maximum water content of 10 %. Wood pellets must
not be exposed to humidity during transport, make sure that they are stored in
an absolutely dry place which is free of dirt.
WOOD
Billet wood (Fig. 2) should have a maximum water content of approximately
30 % of the dried weight, be approximately 1/3 m long and be chopped small.
In this way the billets are ignited rapidly, producing a better heat output than
larger wood billets for the same amount of wood. Undercover in the open, fir,
pine or alder wood should be stored a good 2 years, hard wood even 3 years.
The significance of the water content of wood on the calorific value is shown
in Table 1.
Unsuitable fuels
Moist wood, bark waste, sawdust, fine wood chips, brushwood, wood wool,
wood chips. Use only very small amounts of paper for lighting.
Burning such fuels generates high levels of pollutant emission, a lot of ash
while the calorific value is very low.
Impermissible fuels
Surface-treated wood (veneered, painted, impregnated, etc.), chipboard wood,
all types of waste (packaging waste), plastics, newspapers, rubber, leather,
textiles, etc.
Burning such materials will greatly pollute the environment and is prohibited
by the legislator. It can also damage the stove and chimney. Furthermore the
combustion of carbon energy is not allowed. The appliance has not been tested
for operating on these fuels; therefore damages to the appliance cannot be
ruled out and are not covered by warranty.
