Safety Instructions
Possible Risks
If the combustion chamber door or cleaning openings are left open
during operation, carbon monoxide is able to discharge from the
boiler. Do not leave them open longer than necessary. Insufficient
air supply during operation is lethal. It is prohibited to close the
openings of the boiler or the installation room that provide the
fresh air needed for operation.
This boiler has electric components which are live during operati-
on, as well as movable parts on the inside. Under any circumstan-
ces do not stick a finger or other objects in the openings of the
boiler. There is a danger of electric shocks or burn injury, as well
as property damage.
In case water is leaking from the boiler, stop its operation immedi-
ately and have competent service personnel at the damage.
Minimum Distance Of Flammable Materials
Keep flammable materials and objects away from the boiler and
make sure that the insulation material below the boiler protects
the floor from harmful heat exposure. The minimum distance flam-
mable objects have to be kept abway from the boiler is stringently
prescribed and is subject to regional directives. Ask your chimney
sweep for detail information.
In case the boiler is not installed in a seperate boiler room but in
the living space with an open flue, combustion air is taken from
the living space as well.
The minimum distance from the boiler and its exhaust pipe to-
materials with low or intermediate flammability is 100 mm. The
minimum distance from easily flammable objects is 200 mm. The
latter also counts for materials if their flammability is unknown.
Fresh Air Intake
Boilers need a suitable air supply to maintain combustion.
Open Flue:
Under certain circumstances, if the fresh air is ta-
ken directly from the boiler room, an insufficient supply of oyxgen
needed for combustion may occur. This is especially prominent in
houses or flats with tightly sealed doors and windows. Operating
the boiler without constant supply of outside air can cause sevee
problems in operation. It is recommended to install an automatic
venting system in the builduing or use a balanced flue system.
Balanced Flue:
The fresh air opening is connected with a sealed
pipe which takes air from the outside or a seperate room with
constant fresh air supply. Keep the air supply pipe as short as pos-
sible. It is recommended to install the pipe with the capability to
be shut off (according to EnEV) to prevent humidity from entering
during longer operation pauses.
Avoid using combustion air from the flue. Because of the flue drau-
ght, there is always negative pressure.
The simultaneous operation of artificial ventilation (e.g. cooking
hood) and the pellet boiler in the same room is prohibited. The air
suction may cause problems in boiler operation and discharge of
carbon monoxide.
Talk to your chimney sweep about regional prescriptions
regarding air supply.
