Multiple occupancy
All Austroflamm fireplace inserts in this manual have been checked and approved under DIN EN
13229 with self-closing and locking door (designated BA1). Appliances intended to operate BA1 can
be connected to a multiple-occupied chimney (if multiple occupancy is possible). The calculation is
made according to DIN EN 13384 Part 2.
NOTICE
Multiple occupancy of the chimney is not allowed with balanced flue operation!

Flue pipe connecting pieces
The connecting piece must be selected in accordance with DIN EN 13384.
The connection between fireplace insert and heat recovery surface or to the chimney must be made
using steel flue pipes with a minimum wall thickness of 2 mm, or flue pipes made of austenitic, non-
rusting steel with a minimum wall thickness of 1 mm.
The connecting piece must be connected directly to the chimney.
The connecting piece inside the cladding must be covered with at least 3 cm thick, dimensionally
stable, non-flammable insulation material of Class A1 as per DIN 4102, as described in the section
Thermal insulation layers and materials.
This does not apply to connecting pieces that are intended for heating convection air and for which
fire hazard is otherwise excluded.
