CHAP.05 DESCRIPTION
05.1 PRODUCT PRESENTATION
Jolly-Mec products are the result of over forty years experience in the wooden biomass
combustion sector; they are designed and engineered to meet the increasing demands of
today’s markets with high performance levels and savings enveloped in a modern design.
The MEC 21-18 kW Boiler, approved according to European EN 303-5:2012 standards at
a third party authority accredited by the European Commission as a machine inspection
and certication institute, is a high performance electronic controlled device in closed
circuit for water heating powered with an ECOLOGIC and ECONOMIC energy fuel: wood
pellets.
The MEC 21-18 kW Pellet Boiler is a single-body heater with a heat exchanger in special
steel and a particular ue gas pass whose designed structure allows it to make maximum
use of the heat produced by combustion to achieve high performance that places it at the
top of its category for efciency and emissions, i.e. Class 5. . High yield, over 90%, and
reduced polluting emissions are the characteristics that allow this device to be included
in the most advanced product range on the market, permitting high energy savings and
fast returns on initial investments thanks to the excellent ratio between heating power and
costs provided by an innovative fuel such as pellets. It works with forced draught, with a
pellets combustion fan and an 80 mm diameter exhaust pipe located on the rear of the
boiler. Pellets are feed from the bottom, directly in the basket through a double worm screw
driven by gear motors.
The MEC 21-18 kW Pellet Boiler can heat an entire home in total autonomy over an area
up to 130 m2(or higher in the case of using a buffer).
It can be connected to a radiator or oor heating system and it comes with a previously tested standard closed tank hydraulic kit.
Combustion is controlled by means of a radio-frequency electronic control unit with the following main functions and features:
• Remote control display Ample LCD screen that provides an interface with the product to set function
values and read data on work status.

• Water circulator for the heating system
Standard cladding of the MEC 21-18 kW heat boiler includes the following components:
• Steel Top in two parts: the front piece tilting backwards for pellets manual lling and the rear piece provided with a passing
hole for automatic external pellets feeding pipe
• Right-Left side panels hooked by pressure and easy removable for maintenance
• Front closing door as completion panel of the cladding
The various elements of the cladding must be handled carefully, as being satin-nished, polished or painted, they could be scratched or
dented during the handling or assembly phases.
The Boiler comes packaged with a dust-proof cellophane hood secured within a wooden crate.
*Fully empty net container capacity is about 60 kg. The optional minimum level sensor indicates when pellets in
the container weigh less than 15 kg, for which the working capacity when the AL 23 – PELLET LEVEL alarm triggers,
indicating that pellet level has dropped under the minimum, is about 45 kg.

Please be aware that to have a 18 kW output, approximately 4.20 kg of pellets per hour must be burned.
The declared output may vary according to fuel type
The above technical specications were measured with certied quality PELLETS. ONLY use this type of fuel as
recommended later in CHAP.06.2 - RECOMMENDED FUELS.
All appliance tests, nal inspection and ne-tuning was performed using the recommended certied pellets. Jolly
Mec Caminetti S.p.A. is not responsible for malfunctions, breakdowns or problems due to the use of pellets that are not
recommended, as combustion parameters vary according to the quality of the pellets.
To achieve best operational results, it may be necessary to change the default factory settings on the control unit during
the optional Commissioning service. These operations must only be performed by a specialised Technical Service Center.

06.2 RECOMMENDED FUELS
A pellet product’s performance is signicantly linked and highly inuenced by the type and quality of wooden pellets that is burned. It is
important to choose pellets that have no debris or impurities. The Association of Pellet Manufacturers with the Italian Thermotechnical
Committee have established standards for identifying pellets in terms of energy*.
As the efciencies of different wooden PELLETS qualities differ, likewise the efciency and heat capacity emitted by the product running
on pellets will vary. Similarly, unburned residue left in the combustion chamber is inversely proportionate to pellet quality: the lower the
pellet purity, the faster dirt accumulates in the machine.
Jolly Mec Caminetti S.p.A recommends the use of the same type of pellets used during the optional Commissioning service, i.e. when the
settings and calibrations were made to suit the loaded combustible materials. Continuous switching of types and qualities of combustible
materials will require continuous adjustments to settings by the specialised Technical Service Center, which can not be endorsed by the
Manufacturer.
The main quality certications for PELLETS on the European market are DIN Plus, Ö-Norm M7135 and UNI EN ISO 17225-2 (class A1
or A2), which guarantee the following quality standards:
Store pellets at least 1 m from the appliance, in a dry place and not outdoors, not even under porches or roongs.
Do not use pellets that are very hard and with different dimensions; the mechanical parts are sized and tested for use with pellets with
the above-mentioned characteristics.

WHAT YOU SHOULD KNOW ABOUT PELLETS:
pellets are obtained by a drawing process using sawdust discarded by virgin wood processing systems and therefore
have no chemical additives. The consistency, compactness and strength with which the pieces remain intact is due to a
substance contained in wood called lignin; this acts as a binder during the compression phase.
The various qualities of combustible materials can also depend on the sawdust mix used to produce the pellets, which
generally have a standard length of between 5 and 30 mm, a diameter of between 5 and 6 mm, a weight of from 600 to
700 Kg/m3 and a humidity of no more than 8% of its weight.
One advantage over wood is its greater heating power; in fact, when using good quality wood, it is possible to achieve
about 4.3kWh/Kg with a humidity rate of up to 15%, whilst with pellets this can climb to 4.9kWh/Kg and a water content
of a maximum of 8%.
The sacks of pellets must be stored in a clean, dry place.

06.4 OPTIONALS
Automaticclosingboxforexternalairpassageway:
Installed on the external air passageway, it only allows for air
intake when actually necessary, closing the cold air passage
when the generator is not running to thus avoid cooling the
installation room
Insect-proofgrate230x230mm:
Installed on the exterior of the comburent air intake, it prevents
insect entrance within the home. The mesh must be periodically
cleaned since dust, pollen or humidity can obstruct air passage
through the grate over time.
FumeexhaustpipeL1000mmØ100mm:
Metallic pipe used to connect the generator to the ue.
FumeconnectionpipeL300/L250mmØ80mm:
Metallic pipe used to connect the generator to the ue.
Remotethermostatmodule:
Installed in the home, it is used to easily control stove operations
and adjust necessary temperatures from within the home.
Temperature time settings or personalised heating proles can
be set.
Zone module:
Essential device for correct zone control with the pellet stove.
The module can separately manage systems with zone valves
or systems with zone circulators and a secondary Puffer intake
circulator.

CHAP.07 POSITIONING AND CONNECTIONS FOR THE INSTALLER
07.1 HYDRAULIC CONNECTION AND EXTERNAL AIR INTAKE SETTINGS
The device must only be installed indoors and on surfaces that can support the load. If the existing construction does not meet this
requirement, it will be necessary to take appropriate measures (e.g. installing a load distribution plate). The appliance must be installed
in an area where the appliance itself, gas exhaust pipes and ue can be easily accessed for maintenance.

e
Fig. 2
illustrate pipe functions and minimum distances
that must be observed, All measurements are in mm.
The lateral distance from the adjacent wall, according to
installation, is to be maintained on both sides.
1. Network Load Inlet for Cold Water 1/2” F.
2. Boiler Drain 1/2” F.
3. Heating plant Flow piping 3/4” M.
4. Heating plant Return piping 3/4” M.
5. Safety Valve Fitting 1/2” F.
6. Combustion Air Inlet Ø80 mm.
