Inspection length | Inspection opening

Inspection openings must be installed in each exhaust system. The opening helps the chimney sweep to clean the stainless steel chimney. At regular intervals the chimney sweep has to free exhaust systems from soot. The inspection opening facilitates the cleaning and maintenance of the system. The installation height of the inspection opening is determined according to country regulations and in consultation with the chimney sweep.

However, the accessibility to the cleaning opening must be guaranteed at all times.
