1.9 Causes of faults
Your stove is built to the latest technical know- how. Nevertheless faults may occur, which
are caused by the chimney, fuel or the heating and plumbing.
Fault Check / Rectify
Stove smokes
- in summer
- in winter
- when commissioning
- open the ash door briefly. High outside temperatures
cause poor chimney draught.
- warm up chimney with a paper fire in the chimney or
warm up in stove.
- open the ash door briefly.
- do not use damp or smoke intensive fuel.
- fill the fire box slowly, bit by bit.
- when was the stove last cleaned?
- a short period with some smoke when the stove is first
commissioned is quite normal and will soon disappear.
Stove does not draw properly - is the draught from the chimney too weak?
- is the pipe connection from oven to chimney leaking?
- are all cleaning doors on the chimney and on the stove
properly closed?

stove is installed? Doors and windows should not be abso-
lutely air tight.

To little heat when cooking
and roasting - is the temperature control set at "3"?

Operating temperature not
reached - was energy rich fuel used (Fuel)?
- is the installation properly dimensioned?
