4.2.1 Straight wall vent
For instructions on how to install the straight wall vent also refer to paragraph “10. SEQUENCE FOR INSTALLING A STRAIGHT
WALL VENT”.
• Measure wall thickness and cut the supplied pipes to wall size plus 5 cm.
• Install seals Dto pipes Aand insert the latter, thus prepared, into stub pipes Cof the equipment, using sliding agent to help insertion
if necessary (see gures 10 and 11). Make sure that seals are properly in place and do not obstruct air or ue gas passage.
• Fasten equipment to the wall by means of the supplied screws and anchors.
• If equipment is installed under a shelf or windowsill made from ammable material, protect its lower part using a sheet of
insulating material.
• If equipment is installed under a windowsill (usually made from marble), it is always advisable to insulate its lower face to
minimise heat dispersion to the outside.
• Fasten intake and vent terminal Bto the external wall using the supplied screws, avoiding to cement the pipe in order to allow
equipment removal in the future, if necessary. Close any gaps with rock wool.
WARNING
It is compulsory to fasten the intake and vent terminals to the external wall in a secure manner.
WARNING
The air necessary for combustion is taken in through the slits on the
external wall (g.11), which should hence be free: avoid cementing or
using sealants of any kind.
It is always preferable to install the supplied stainless steel disc (A)
(g.11).
WARNING
Pipes must be slightly slanted downwards to allow drainage of any condensation.
4.2.2 Vent pipe with extensions or elbows
Gazelle EVO allows the use of extensions and elbows for intake and vent pipes.
This allows for a wide range of solutions to overcome installation issues connected with the impossibility of direct venting.
35 mm and 60 mm diameter pipes are available.
WARNING
Condensation occurs more easily when using pipe extensions. To prevent it from entering the heat exchanger, always
use the suitable accessories for draining condensate.
Condensate draining accessories must be connected to a trap having a head of at least 10 cm.
WARNING
Insulate the vent pipes!

The gures 13 A / B show a few examples:
To extend the vent, the splitter kit can be used with support bracket, or the pipes can be connected directly to the equipment. In this
latter case, follow this procedure:
• Install seal Don adapter F (g.13 A).
• Use sliding agent if necessary to engage adapter Finto stub pipe C (g. 9) and fasten it to equipment base with screw Y(supplied)
(g. 13C).
• Insert pipe Ø 35 mm or 90° elbow into adapter, putting the relevant seal G in-between, to be tted in the coupling of the elbow or
pipe (g. 13 B).
• Elbows Ishall be fastened to the base by means of the suitable brackets S supplied in the splitter KIT (g 13 C).
• To join an elbow to a pipe or put two pipes together, engage and cover them with the seal H (g.13 B).
• Insert terminal Lon the pipe, pulling the relevant closing screw V. Intake and vent terminals are the same. If 35 mm pipes run
parallel, use the standard intake/vent terminal (g.14 A).
When splitting pipes, they can be installed recessed in the wall or onto the walls.
If pipes must be installed along the walls, the suitable spacer support supplied as accessory can be used (g.15)

4.2.3 Roof vent
When using the roof vent, the accessory (diameter 60 mm) must be used as a vent terminal.
The nal pipe must then be diameter 60 mm: if the pipes used are 35 mm, it will be necessary to use the adapter W 35/60, available
as an accessory (Fig. 18).
