3 Safety
In this manual we give you numerous safety instructions for the safe operation of your fireplace insert.
These instructions are characterized differently as follows, depending on their importance:
3.1 Importance of the safety instructions
NOTICE
Particular behaviour and/or activities that are required for safe working. Failure to follow this can result
in material damage.
CAUTION
Possible dangerous situation (light or minor injuries and material damage).
WARNING
Possibly imminent danger to life and health of persons (severe injuries or death).
DANGER
Immediately imminent danger to life and health of persons (severe injuries or death).
3.2 Warning of sources of danger
3.2.1 General safety instructions
• It is strictly forbidden to burn or introduce highly flammable or explosive substances, (such as
empty aerosols and the like) into the firebox or to store them in the immediate vicinity of the fire-
place due to the risk of explosion!
• Please note that the the surfaces of the fireplace insert heat up considerably during operation. To
operate your fireplace insert, we recommend that you use the protective glove supplied with it.
Please alert children to these dangers, and keep them away from the heat-producing appliance
when it is operating.
• Placing non-heat-resistant objects on the stove or in its vicinity is forbidden. This also applies to air-
ers -> fire hazard!
• While the heat-producing appliance is in operation, it is forbidden to process highly flammable or
explosive substances in the same room or in adjoining rooms.
• To avoid a build-up of heat in the chimney, the warm air grilles must not be closed during heating
operation.
• Fireplace inserts tested to type A1 are fitted with a self-closing firebox door. This means that oper-
ating with the firebox door open is not permissible. To stoke up the wood the hinged door must
be kept open against the tension force of the springs. The door must not be jammed open with
clamping devices.
• Only spare parts which are specifically approved or offered by the manufacturer may be used.
Please contact your specialist dealer if necessary. Failure to comply with this may cause loss of war-
ranty!
Please also read further information in the section Fuel.

3.2.2 Safety distance
Fig.1: Dimension “a” as per technical data
(front minimum clearance)
No flammable objects may be placed within the radiation
area of the fireplace insert up to a certain distance (see
Technical Data [}auf Seite 15]) measured from the front
edge of the firebox opening (a minimum clearance in the
Technical Data).
3.2.3 Special types of danger and personal protective equipment
For certain activities such as installation/dismantling, particular care must be taken that the following
safety equipment is worn:
Safety gloves
Safety shoes
