"Straight length" means with terminals and joints but without bends.
The boiler is supplied without the flue,
Allowing you to use the accessories for condensing appliances that
most suit the installation characteristics (see catalogue).
.
It is compulsory to use the Beretta flue components.
Flue gas outlets are potential sources of danger. Ensure they
remain clear
The use of longer flue causes a minor loss of output of the boiler
Make sure the flue gas discharge pipe is tilted 3° towards the
boiler.
The boiler is designed to take in and dispose of flue gas
condensate and/or meteoric water condensate deriving from the
flue gas discharge system using its own siphon.
Flue installation
Concentric pipes (ø 60-100 mm)
- Position the bend so that the Ø 60 pipe goes fully into the f lue gas
turret of the boiler.
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the bend.
- Fully tighten the two locking terminals of the flange (C) so the bend itself
is restrained.
-
Twin pipes (ø 80 mm)
SPIECIAL
The combustion air suction pipe should be selected from the two inputs,
remove the closing plug fixed with the screws and ix the specific air
deflector.
- Position the adaptor on the flue gases pipe so that the Ø 60 pipe goes
fully into the flue gases turret of the boiler
- Once positioned, make sure that the 4 notches (A) on the flange connect
to the groove (B) on the Ø100 of the adaptor.
- Fully tighten the two locking terminals of the flange (C) so the adaptor
itself is restrained.
