2. For the Installer
2.6.2 Minimum service clearances with flue gas tube connection
straight back
Dimension Clearance Description
a 800 mm Minimum clearance in radiation area (front window) from flammable materials
b 600 mm Minimum lateral clearance from non-movable objects (e.g. wall)
c 50 mm Minimum lateral clearance from movable objects (e.g. furniture)
f
400 mm Minimum clearance from flammable walls with non-insulated exhaust pipe
200 mm
Minimum clearance from flammable walls with insulated exhaust pipe (20 mm)
2
Minimum clearance from flammable walls with tested double-walled insulated
exhaust pipe, acc. to accreditation of connecting piece
3
Note!
The intake air line must be non-flammable (e.g. flexible aluminium tube) if the exhaust pipe is unin-
sulated.
If the walls are non-flammable, there are no fire protection reasons for a minimum service
clearance from the exhaust pipe and no need to insulate the exhaust pipe.

1 When the fully automated feed unit FIRE 040 is installed subsequently, the pellet flue-connected boiler must be closed again by a heating expert. Subsequent
installation is highly complicated and can only be done by our customer service, with charging based on the actual work done.
2 Technical data for exhaust pipe insulation: Mineral wall insulation; melting point: >1000 °C; thermal conductivity: < 0.04 W/mK
3 The minimum service clearance is determined by the design specifications (Ø of the double pipe) of the flue gas system used or the minimum service clea-
rances demanded in the accreditation.
