1.21 CONCENTRIC HORIZONTAL KIT INSTALLATION.
• Type C configuration, sealed chamber and fan assisted.
The position of the terminal (in terms of distances from openings,
overlooking buildings, floor, etc.) must be in compliance with the
regulations in force.
This terminal is connected directly to the outside of the building
for air intake and flue gas exhaust. The horizontal kit can be
installed with the rear, right side, left side or front outlet. For
installation with frontal outlet, one must use the fixing plate and
a concentric bend coupling in order to ensure sufficient space to
carry out the tests required by law upon commissioning.
• External grid.
Both the Ø 60/100 and Ø 80/125 intake/exhaust terminal, if
properly installed, is pleasant to look at on the outside of the
building. Make sure that the external silicone wall sealing plate
is properly inserted in the wall.
ATTENTION:
for correct functioning of the system
the terminal with grid must be in-
stalled correctly ensuring that, the "high"
indication present on the terminal is respect-
ed on installation.
Horizontal intake-exhaust kit Ø 60/100. Kit Assembly.
(Fig. 21).
Install the curve with flange (2) on the central hole of the in-
door unit, positioning gasket (1) with the circular projections
downwards in contact with the indoor unit flange, and tighten
using the screws contained in the kit. Fit the Ø 60/100 (3) concen-
tric terminal pipe with the male side (smooth) to the female side
of the bend (2) up to the end stop; making sure that the internal
and external wall sealing plate have been fitted, this will ensure
sealing and joining of the elements making up the kit.
•
Extensions for Ø 60/100 horizontal kit (Fig. 22).
The kit with this configuration can be extended up to a max.
horizontal length of 12.9 m including the terminal with grid
and excluding the concentric bend leaving the indoor unit. This
configuration corresponds to a resistance factor of 100. In this
case the special extensions must be requested.
Immergas also provides a Ø 60/100 simplified terminal, which in
combination with its extension kits allows you to reach a maxi-
mum extension of 11.9 metres.
Horizontal intake-exhaust kit Ø 80/125 Kit Assembly.
(Fig. 23):
to install the kit Ø 80/125 one must use the flanged adapter kit
in order to install the flue system Ø 80/125. Install the flanged
adaptor (2) on the central hole of the boiler, positioning gasket
(1) with the circular projections downwards in contact with the
boiler flange, and tighten using the screws contained in the kit.
Engage the bend (3) with the male side (smooth) to the end stop
on the adapter (1). Fit the Ø 80/125 (5) concentric terminal pipe
with the male side (smooth) to the female side of the bend (4)
(with lip seals) up to the end stop; making sure that the internal
(6) and external wall sealing plate (7) have been fitted, this will
ensure sealing and joining of the elements making up the kit.
• Extensions for Ø 80/125 horizontal kit (Fig. 24).
The kit with this configuration can be extended up to a max. length
of 32 m, including the terminal with grid and excluding the con-
centric bend leaving the indoor unit. If additional components are
assembled, the length equivalent to the maximum allowed must be
subtracted. In this case the special extensions must be requested.
