The owner of small firing systems or the person authorised for the

submit it to the authorities or the chimney sweep on request.
Note
Please observe the national and European standards as well as
local regulations concerning the installation and operation of

Packaging
Your first impression is important to us!
The packaging of your new stove provides excellent protection
against damage. However damage to the stove and accessories
may still occur during transport.
Note
Therefore please check your stove on receipt for damage and
completeness! Report any deficiencies to your dealer immediately!
Pay particular attention during unpacking that the stone panels
remain intact. Scratches to the material can easily occur. Stone
panels are excluded from the warrant.
The packaging of your new stove is environmentally neutral to a
great extent.
Tip
The wood used in the packaging has not been surface treated.
The cardboard and film (PE) can be disposed of via the municipal
waste collection for recycling.
Electrical connection
The stove is supplied with an approx. 2 m long connecting cable with
shock-proof plug. This cable is to be connected to a 230 Volt/50 Hz
socket. The average electrical power consumption is some 20 Watt in
heating operation, and approx. 150 Watt during automatic ignition.
The connection cable must be laid so that there is no contact to any
sharp edges or hot surfaces of the stove.
