INSTALLATION ROOM VENTILATION
According to reference regulation UNI10683, 4 Pa depression must be verified between the installation room interior and exterior. Prepare
ventilation openings of at least 80 cm
2
in the room where the product is installed to allow the inflow of clean oxidizing air taken from
unpolluted rooms. The ventilation openings, if fitted with insect-proof mesh, must be easily removable and undergo periodic cleaning to
ensure clear air flow passage.
If the comburent air inlet is directly connected to the stove, it may be necessary to make adjustments to the control unit, especially during
the start-up phase, as the temperature and humidity of outdoor air not only varies during the period of use of the product, but also come
into direct contact with the pellets and the ignition element, generating different fuel burning times.
Here below you will find the indications for the realization of externally connected direct air intake:
• Over a length of 0 to 1 m, the diameter of the air intake fitting shall be 80 mm, with only 1 possible change of direction of 90° maximum,
and a difference in height of up to 50 cm downwards or 20 cm upwards.
• On a length between 1m and 3m, the diameter of the air intake fitting must be 100mm, with only one change of direction of up to 90°
and a height difference of up to 50 cm downwards and 20 cm upwards.
• Above 3 meters, and up to 5 meters maximum, the diameter of the air intake fitting must be 125mm, always with only one change of
direction of up to 90°, and a difference in height of up to 50 cm downwards and 20 cm upwards.
Jolly Mec authorizes a direct air intake fitting above 5m on products and recommends an installation only under technical project.
In order to ensure a proper installation and good operation of the product, Jolly Mec offers an external air intake fitting as an option:
diameter 80 mm for a maximum developed length of 1 m.
As per the fuel product exhaust system, air vents are also extremely important and must be given the appropriate
consideration and respect.
The installer is directly liable for all electrical system parts, generation hook-up to the system, ventilation and the fume
exhaust system and MUST, at the end of installation work, issue a declaration of conformity as per Ministerial Decree 37/08.
On the other hand, the purchaser MUST assign all work to a qualified professional technician.
The device must be installed and used in accordance with all local and national laws and EC Regulations.
WARNING
In the event of a black-out, suitable sizing of the fume exhaust system guarantees sufficient draught to exhaust the fumes generated by
combustion without the use of the electric exhaust fan.
If the performance of the fume exhaust system is not excellent, it is possible to adjust the operating settings of the stove to overcome
draught defects by a maximum of 15% of the fume exhaust device; this adjustment is however the exclusive competence of the
specialised Technical Service Center.
Supporting the weight of the flue with the appliance union is strictly forbidden. Use specific stands or independent supports for this
purpose.
To install other combustion devices in the same room where the pellet appliance is installed, refer to UNI 10683 and UNI 7129 installation
regulations.
The minimum flue height must be over 3,0 m.
Blocking of wall exhaust terminals at any height and any distance from openings, doors and/or windows is not permitted and a very
important rule to follow.
Installation of external fireplaces must be performed using insulated double-walled pipes, to prevent the formation of condensate; it must
also be possible to inspect the base of the fireplace for routine maintenance which must be done at least once a year.
A windproof chimney cap must be installed; in the presence of adverse weather conditions, especially high winds, this accessory allows
the stove flue draught system to operate much easier.
A minimum flue draught between 10 and 14 Pa must be guaranteed. This value must be measured using specific and controlled
instruments each time the appliance and flue undergo maintenance.
With strong winds and the chimney cap installed in the reflux area (see

,
zone bordered by the dotted line A for roofs with ß>10° slant) of the roof or
without complying with the distances foreseen by UNI 10683 situations may
arise where the stove does not work which will trigger the no depression alarm.
It is not possible to make corrections or reset the stove operating values to
override the alarm.
It is only recommended to connect the comburent air ducting system to the stove if absolutely necessary. Very
cold air and humidity may cause difficulties during the stove ignition phase.
NOTE
It is not allowed to install coaxial systems for the smoke output.
