LIRA SLIM PLUS
EXAMPLES OF CORRECT CONNECTION TO THE FLUE
1 Installation of flue with hole for the passage of the pipe increased by:
▪ minimum 100 mm around the pipe if communicating with non-flammable parts such as concrete, bricks, etc.;
or
▪ minimum 300 mm around the pipe (or as per the dataplate) if communicating with flammable parts such as wood,
etc.
In both cases, insert suitable insulation between the flue and the floor.
Check and respect the flue dataplate, in particular the safety distances from combustible materials.
The above rules also apply to holes made in the wall.
2 Old flue, ducted with the creation of an external door to allow cleaning of the chimney.
3 External flue made exclusively with insulated s/steel pipes, i.e. with double wall: all well-anchored to the
wall. With antiwind grille.
4 Ducting system using T-pieces, allowing easy cleaning without disassembling the pipes
