on the pipe as close as possible to the appliance. To limit
the formation of condensate, it is in any case advisable to
insulate the flue gas pipe with a material resistant to high
temperatures.
Due to the high temperatures that the flue gas pipe
can reach, it is still advisable to insulate it from the
wall and from potential contact with things and
people, for example by using rock wool or glass
wool.
The flue gas exhaust terminal, if used only for flue
gas exhaust, must also be protected against acci-
dental contact with people and things, due to the
high temperatures it can reach.

INSTALLATION PROCEDURE
In accordance with the installation project, prepare the
gas and electrical supply lines, as well as the holes for the
flue gas outlet and combustion air intake.
3.5.1
Install the gas-fired convector on the wall
1. Check the packaging for visible signs of damage, oth-
erwise, notify the carrier immediately.
2. Remove the gas-fired convector from its packaging
by first removing the air intake and flue gas exhaust
pipes. Do not damage or discard the cardboard jig
with the drilling template required for installing the
gas-fired convector.
3. Fix the jig to the wall where the gas-fired convector is
to be installed, making sure it is perpendicular to the
floor.
4. Drill the hole (Ø 50 mm) to house the larger pipe and
holes A (Figure 3.6
p. 15) to fix the support brack-
et (drill 6 mm holes to insert the provided wall plugs).
The Ø 50 mm hole for the duct can be made with a
suitable core drill or by means of a succession of small-
er holes made with a simple drill on the perimeter to
be removed.
5. Adjust the length of the pipes (air intake and flue gas
exhaust) to the actual thickness of the wall by cutting
off the excess length: to determine the exact length
see diagram Figure 3.5
The coaxial duct must in any case not be less than
20 cm in length (flue gas pipe 200 + 33 mm, air in-
take pipe 200 + 2 mm).
In the Ø 49 pipe, do not cut the side with the
edging, which will later be used to secure the pipe.
In the Ø 35 pipe, do not cut off the side with a skirt-
ed end that will be used to fit the pipe to the gas-
fired convector.
6. Remove the jig from the wall.
