4 BASIC RULES FOR OPERATION
The service life and functionality of the heating insert depend on correct as-
sembly, proper operation and regular care and maintenance.
The fireplace doors should be opened only for loading firewood or clean-
ing. BRUNNER heaters are designed and optimized for closed operation.
When the fireplace door is open, other fireplaces connected to the same
chimney might be impaired. Under certain circumstances this could lead
to a risk of flue gas poisoning. The fireplace door must always stay closed,
even if the fire is not burning.
Avoid overheating the device! The oven will overheat if it is loaded with
more than the specified maximum amount or if sufficient heating pauses
are not observed.
Stoves and fireplaces from Ulrich Brunner GmbH are designed for period-
ic burning. It means that always a minimal amount of firewood has to be
loaded and the combustion air must be adjusted according to the following
instructions. Insufficient volumes of combustion air will lead to higher emis-
sions and increased staining of the glass door.
Avoid risk of overheating! If the stove temperature is often too high, this
can cause discolorations, especially in the case of stainless steel frames.
Such defects do not constitute a reason for a claim.
Stoking wood
For stoking up we recommend to use a protective glove or the “cold
hand” (delivered with some models), because the door handle gets very
hot after several hours of burning. Open the door slowly. This will avoid
turbulences, which could draw the smoke into the room. The right time for
stoking up is when the wood turned almost completely into glowing em-
bers.
