bottom in the appliance.
The appliance must be inspected by the
installer for the air tightness of the gas supply
and flue gas duct. The operation of the control
valve, the thermocouple circuit and the ignition
of the burner must also be checked.
When the appliance is ready for use, have your
installer tell you about its use, operation and
maintenance.
Use only the supplied ceramic wood block set,
coals or stones.
Place the log set exactly according to the
description.
Keep the area around the pilot flame free of
coal.
Avoid dirt in the gas pipe.
Always close the gas valve if the appliance is
not in use.
If you notice a gas smell, immediately close
the main valve, open windows and avoid fire or
the use of electrical contacts, such as
switches, because of the sparks they can
cause. Always call in an expert to trace a pos-
sible gas leak.
Installation
requirements

General

The appliance must be connected tightly to a well-
functioning flue.
For connection measurements: see "Technical
data" appendix.
Ask the fire service and/or your insurance com-
pany about any specific requirements and reg-
ulations.

The chimney

The chimney (the flue pipe) has a double function:
It extracts the air from the room, which is neces-
sary for incinerating the fuel in the stove or
Subject to change because of technical improvements
fireplace.
It removes the combustion gases by means of the
thermal and natural draught. The thermal draught is
created by the temperature difference between the
air inside and outside the flue pipe. The warm air in
the flue pipe is lighter than the cooler air outside the
pipe and therefore rises upward together with the
combustion gases. Natural draught is caused by
environmental factors such as the wind.
It is not permitted to connect multiple appliances to
one chimney (for example, the central heating boiler),
unless approved on the basis of local or national reg-
ulations.
Check which chimney is necessary for the appliance
in question, and whether the existing chimney is suit-
able and complies with the applicable standards. Ask
a specialist for advice.
The chimney must comply with the following general
conditions:
The flue pipe must be manufactured from fireproof
material. Ceramic or stainless steel elements are
recommended.
The chimney must be airtight, must have been prop-
erly cleaned and must guarantee an adequate
draught.
The chimney must be as vertical as possible, start-
ing from the outlet in the appliance. Changes in dir-
ection and horizontal sections are not
recommended as they can disrupt the removal of
flue gas.
The interior dimensions of the chimney may not be
so large that they cause the flue gases to cool off
too fast. For the recommended chimney diameter:
See the appendix "Technical data". If the flue pipe
is extremely well insulated, a larger diameter may
be used.
In particular, the dimensions of the section of the
flue pipe must be consistent. Wider sections, and
particular narrower sections, disrupt the rapid
removal of flue gas and must be avoided. The
same applies to a cover plate or extractor hood on
top of the chimney. Be careful that this does not
constrict the protruding section, and make sure
that the hood is designed so that when there is
wind it actually speeds up rather than obstructs the
removal of the flue gases.
