1.23 SEPARATOR KIT INSTALLATION.
Type C configuration, sealed chamber and fan assisted.
•
Separator kit Ø 80/80.
This kit allows air to come in from outside the building and the
exhaust to exit from the chimney, flue or intubated duct through
divided flue exhaust and air intake pipes. Combustion products
are expelled from pipe (S) (in plastic, so as to resist acid con-
densate). Air is taken in through duct (A) for combustion (this
is also in plastic). The intake pipe (A) can be installed either on
the right or left hand side of the central exhaust pipe (S). Both
ducts can be routed in any direction.
•
Kit assembly (Fig. 29).
Install the flange (4) on the central hole of the indoor unit, po-
sitioning gasket (1) with the circular projections downwards in
contact with the indoor unit flange, and tighten using the hex
screws with flat tip contained in the kit. Remove the flat flange
present in the lateral hole with respect to the central one (ac-
cording to needs) and replace it with the flange (3), positioning
the gasket (2) already present in the boiler and tighten using the
supplied self-threading screws. Fit the male side (smooth) to
the bends (5) in the female side of the flanges (3 and 4). Fit the
intake terminal (6) with the male side (smooth) in the female
side of the bend (5) up to the end stop, ensuring that the internal
and external wall sealing plates are fitted. Fit the exhaust pipe
(9) with the male end (smooth) to the female end of the bend
(5) up to the end stop; making sure that the internal wall sealing
plate has been fitted, this will ensure sealing and joining of the
elements making up the kit.
•
Installation clearances (Fig. 30).
The minimum installation clearance measurements of the Ø
80/80 separator terminal kit have been stated in some limit
conditions.
•
Extensions for separator kit Ø 80/80.
The maximum vertical straight length (without bends) that
can be used for Ø 80 intake and exhaust pipes is 41 metres, re-
gardless from whether they are used for intake or exhaust. The
maximum horizontal straight length (with bend in suction and
in exhaust) that can be used for Ø 80 intake and exhaust pipes
is 36 metres, regardless from whether they are used for intake
or exhaust. Please note the type of installation C
43
must be done
with a natural draught flue.
N.B.:
to favour the removal of possible condensate forming in the
exhaust pipe, tilt the pipes towards the boiler with a minimum
slope of 1.5% (Fig. 31).
