important: whEn using mEtallic pipEs, thEy must bE insulatEd with propEr matErials (coatings in insulating

before positioning the insert in the pre-existing fireplace, it is necessary to close the upper internal part of the stack using
(properly pre-drilled) sheet metal or any other kind of fire-resistant material that can support very high temperatures without
suffering any damage. (see

dEflEctor of thE firE-proofing matErial of thE hood.
for this reason, it is necessary to foresee an intake of air from the bottom (intake of fresh air) and a high output (output of hot air).
Each of these openings must be free and it should not be possible to obstruct it; moreover, they must have a minimum surface of at least 3
dm
(example: 30 x 10 cm grating).

in this way, the following targets are achieved:
• a greater safety
• an increase of the heat created by air circulation around the device.
• a better working of the appliance

Ventilation and aeration oF the installation premises
as thE product draw thEir combustion air from thE placE of installation, it is mandatory that in thE placE itsElf, a
sufficiEnt quantity of air is introducEd. if windows and doors arE airtight (E.g. built according to EnErgy saving critEria),
it is possiblE that thE frEsh air intakE is no longEr guarantEEd and this JEopardisEs thE draught of thE appliancE and your
hEalth and safEty.
important: for a better comfort and corresponding oxygenation of environment, the combustion air can be directly withdrawn at the
outside through a junction which is to be connected with a flexible pipe. the connection pipe (not furnished) must be flat with a minimum

a maximum length of 4 m and with no more than 3 bends. if there is a direct connection with the outside it must be
endowed with a special windbreak.
thErE mandatory bE sufficiEnt quantity of air for combustion and rE-oxygEnation of thE room to EnsurE thE dEvicE will
work propErly. there should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even
when the doors and windows are closed.
the air inlets must meet the following requirements:
• thEy must bE protEctEd with grids, mEtal mEsh, Etc., but without rEducing thE nEt usEful sEction;
• thEy must bE madE so as to makE thE maintEnancE opErations possiblE;
• positionEd so that thEy cannot bE obstructEd;
• any Extractor hoods in thE room whErE thE dEvicE is installEd must not opEratE at thE samE timE as this could cause
smoke to enter the room, even with the fireplace's door closed.
the clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and ventilation),
as long as the flow takes place freely through permanent openings communicating with the outside.
thE adJacEnt room cannot bE usEd as a garagE, or to storE combustiblE matErial or for any othEr activity with a firE
haZard, bathroom, bEdroom or common room of thE building.
ventilation is deemed sufficient when the room is equipped with air inlets according to the table:
