3. INSTRUCTIONS FOR THE INSTALLER
This part of the manual contains
installation instructions for gas radiators.
It is for use by qualified fitters, the only
persons authorised to install gas radiators
professionally as prescribed by the current
regulations.
IMPORTANT:
Before installing the radiator, check that
the technical data correspond to the
specifications for the system. The type of
gas to be used and the supply pressure
are shown on the data label affixed to the
radiator.
3.1 CHOOSING A LOCATION
The Gazelle Techno gas radiator can
generally be installed anywhere in the
room to be heated. Please check laws and
regulations for local restrictions.
The radiator comes with straight pipes
measuring 59 cm long, which can be used
whenever it is installed on external walls.
These pipes can be replaced with pipes of
up to 1 m long if required.
It is also possible to install the radiator
on internal walls, using outlet solutions
that involve bends and longer pipes as
illustrated (examples in paragraph 3.2.2).
During installation of the flue gas system, it
is important to comply with the minimum
distances in accordance with the current
laws and regulations of the country in
question.
Gas radiators are room-sealed appliances,
defined by the current European
regulations as “type C”. Both the air-
intake and flue gas pipes are an integral
part of the appliance.
Whenever it is necessary to extend
the flue gas pipes, always use original
accessories by the Manufacturer.
3.2 INSTALLATION
• The package in which the gas radiator is
delivered contains a wall-mounting paper
template. Place it on the wall and drill
the holes as indicated, keeping to the
minimum distance from the ground (see
fig. 7).
• Remove the foam polystyrene protection
and remove the painted casing, taking
care not to damage it. To do this, remove
the two screws, one on either side at
the bottom. Remember to replace them
afterwards.
Use the specific hexagonal spanner
provided (see the picture below).
• If the wall is made partly or entirely of
flammable material, insulate the flue
gas pipe with rock wool at least 1 cm
thick.
3.2.1 Straight flue gas outlet
• Measure the thickness of the wall and
cut off the pipes to that length plus about
5 cm;
IMPORTANT. With reference to fig. 9, the
air intake is on the left and the flue gas
outlet on the right.
• Fit the gaskets D on the pipes A and
insert the pipes in the stub pipes C on the
radiator using some lubricant compound
(figs. 9 and 10).
• Install diaphragm E of the size shown in
the table of technical data on the terminal
end of the air-intake pipe (fig. 11).
• Fix the radiator onto the wall using the
screws and inserts provided.
• If the surface of the wall is made of
flammable material, place a 1-cm layer
of insulating material such as glass
wool or ceramic fibre between the back
of the radiator, the pipe and the wall.
• If the radiator is positioned below
a shelf made of flammable material,
protect the underside with a layer of
insulating material.
• Fix the air intake and flue gas terminal
B to the wall using the screws provided.
It is advisable not to embed the pipe
in concrete to allow the radiator to be
removed at a later stage.
Important! The combustion air is taken
in through slots in contact with the
outer wall (fig. 12) and they must
always be left clear. Do not use cement
or sealants of any kind. If necessary,
install the stainless steel ring-plate A
provided (fig. 12).
• Pipes must slope slightly downwards
to allow any condensate to drain out
and they must be properly insulated.
