USER
AUTHORISED TECHNICIAN
(ONLY to interpret or the Stove-manufacturer or the Authorized Technician of
Technical Assistance Service approved by the Stove-manufacturer)
SPECIALIZED STOVE-REPAIRER
CAUTION:
READ CAREFULLY THE NOTE
CAUTION:
DANGER OR IRREVERSIBLE DAMAGE POSSIBILITY
• The icons with the stylized figures indicates whom the subject dealt in the paragraph is addressed to (between the User and/
or the AuthorizedTechnician and/or the Specialized Stove-repairer).
• WARNING symbols indicates an important note.
2 PACKAGING AND HANDLING
2.1 PACKAGING
• The packaging is made up of recyclable cardboard boxes according to RESY standards, recyclable expanded polystyrene inserts
and wooden pallets.
• All packaging materials can be re-used for a similar use or eventually discharged as waste assimilable to the municipal solid
ones, in accordance with current regulations.
• After having removed the packaging please assure you about the integrity of the product.
2.2 REMOVING THE STOVE FROM THE PALLET
Proceed as follows to remove the stove from the pallet:
Fig. 1 - Screw removal
• Slightly pull out the machine body from the structure (see INSERT EXTRACTION a pag. 13)
• Remove the screws fixed to the base of the insert (see Fig. 1) and then remove it from the pallet.

2.3 STOVE HANDLING
Both whether the stove is packed or not it is necessary to observe the following instructions for handling and transporting the
stove from its sale point to its installation point and for any future movements:
• The stove must be handled with idoneous means paying attention to the existing safety regulations;
• do not turn the stove upside down and/or upset it on one side, but keep it in vertical position or as accorded with the construc-
tor instructions;
• if the stove is made up of ceramic, stone, glass or any particularly fragile material components, all must be moved with the
utmost care.
3 CHIMNEY FLUE
3.1 PREPARING THE SMOKE EXPULSION SYSTEM
The combustion product expulsion system is a particularly important element for the proper operation of the appliance and must
be correctly sized according to EN 13384-1.
Its creation/adaptation/verification must always be carried out by a legally qualified operator and must comply with the regula-
tions in force in the country where the appliance is installed.
The Manufacturer declines all liability for malfunctions caused by a badly sized and non-compliant smoke expulsion system.

3.3 SMOKE DUCT SMOKE FITTING
The smoke duct is the pipe that connects the appliance to the flue.

ZEFIRO3- ZEN AIRTIGHT
This smoke fitting must comply in particular with the following requirements:
• comply with product standard EN 1856-2;
• its cross-section must be of constant diameter and no less than that of the appliance outlet, from the firebox outlet up to the
connection in the flue;
• the horizontal section must be as short as possible and extend no more than 4 metres;
• the horizontal sections must have a minimum upward slope of 3%;
• changes of direction must have an angle no greater than 90° and be easy to inspect
• the number of changes of direction, including that for entry into the flue, and exclusion of the T in the event of a side or rear
outlet, must not exceed 3;
• it must be insulated if it passes outside the installation room
• it must not in any case cross rooms in which it is forbidden to install combustion appliances.
• the use of flexible metal and fibre cement or aluminium hoses is forbidden;
In any case, smoke ducts must be sealed against combustion products and any condensation. For this reason, it is recommended
to use pipes with silicone gaskets or similar sealing devices that withstand the operating temperatures of the appliance (e.g.T200
P1) and that by removing the gaskets, are still T400 N1 G certified.

3.4 FLUE CHIMNEY OR PIPED DUCT
When creating the flue, in particular comply with the following requirements:
• comply with the applicable product standard (EN 1856, EN 1857 EN 1457, EN 1806, EN 13063..);
• be made with suitable materials to ensure resistance to normal mechanical, chemical, thermal stresses and have adequate
thermal insulation in order to limit the formation of condensate;
• have a predominantly vertical configuration and be free of choke points along its entire length;
• be correctly spaced by air gaps and isolated from combustible materials;
• the flue inside the house must still be insulated and can be inserted in an air shaft provided it complies with the regulations
for piping;
• the smoke duct must be connected to the flue by means of aTee fitting with an inspectable collection chamber for the collec-
tion of soot and any condensate.
• where the sizing provides for wet operation, a suitable condensate collection and siphon discharge system must be set up.
We recommend checking the data plates of the flue for the safety distances that must be observed in
the presence of combustible materials and, if necessary, the type of insulating material to be used.
It is forbidden to connect the stove to a collective or shared flue (*) with other combustion appliances
or with hood outlets.
It is forbidden to use the direct drain on the wall or towards indoor spaces and any other form of drain
not provided for by the regulation in force in the country of installation.
