1. PURPOSE
e stove is purposed to heat domestic and public premises by the means of pellets. e
stove is designed and manufactured to work with A-class pellets only ( DIN plus 51731
) with the following characteristics:
What are the pellets.
e pellets are produced by compressed wood-
en waste le from the production of various
furniture, sawmills and others. is type of
fuel is environmentally friendly because in
the production process no agglutinate agents
(glues, resins and others) are added. Actual-
ly, the integrity of the pellets is guaranteed by
the lignite – a natural ingredient contained in
the wood itself. While the wood has a calorie
capacity of 4.4 kW/kg (15% humidity at 18
months drying), the pellets have 5.2 kW/kg.
• Material 100% pure conifer or broad-leaf
wood;
• Diameter Ф6/8 mm;
• Length 20-30mm;
• Calorie capacity 5.2 kW/kg;
• Ash content < 8%;
e use of pellets with characteristics dierent from the recommended may result in
power decrease, unstable and inconsistent work of the stove.
Info: To ensure the proper work of the stove the pellets must be stored in a dry place!
Recharging of pellets can be done during work, with the following sequence:
1. Open the bunker (located at the top rear of the product);
2. Fill the hopper, using non-combustible container;
3. Close the lid of the bunker;
Attention!!! Use gloves! Beware of hot surfaces!

3. ASSEMBLY
3.1 General conditions.
All national, regional and European requirements for safe operation of the appliance
must be respected during installation and operation.
Prior to installation, load capacity of the place where the stove will be intended must be
ensured. e weight of the stove is specied in the technical data table.
To ensure the correct and safe operation of the stove, the following conditions must be
met:
e installation of the stove and its accessories must be carried out by authorized per-
sons.
e oor where the stove is installed should be at and horizontal, made of re-resist-
ant materials at least 1500 mm in front of the replace and not less than 400 mm on
both sides and at the back of the wall.
Minimum distances from the wall to the stove should be at least 400 mm. e mini-
mum space in front of the replace should be 1500 mm. e minimal distance of the
stove from combustion materials should be no less than 1500 mm.
e door of the replace should be closed tightly during the work process. Opening it
during work is absolutely forbidden.
When installing the stove, the connections between the individual pipes and the chim-
ney rooop must be dense.
When the re is rst ignited, a smell occurs as a result of the paint being heated.
e replace is painted with heat-resistant paint, which achieves its ultimate resist-
ance aer repeated use of the stove. THEREFORE KEEP OUTSIDE INTERACTIONS
WITH THE COATING TO A MINIMUM in order not to damage it.
A. A neighboring wall.
B. e rear wall.
C. Sidewall.
D. Floor protection.
E. Ignitable element.

3.3 Assembly of the duct components.
Duct components and pipes
For the assembly of the duct pipes the use of non-ammable materials, resistant to the ammable
products and condensation is obligatory. e assembly must be performed in such a manner so
it guarantees the airtight sealing and prevents condensation. If possible, avoid adding horizontal
sections. Direction shi is done by using knee joints with a max angle of 45˚.
For heating devices equipped with a smoke ventilator, i.e all of the “MARELI” stoves, the follow-
ing instructions must be observed:
Chimney
e chimney or the duct component must conform with the
following requirements: to be airtight, waterproof and prop-
erly insulated, to be constructed with materials resistant to
the normal mechanical wear and to the heat coming from the
combustion products and condensation.
• To be kept away from ammable materials.
e recommended chimney dra at work - from 12-20 Pa.
• Horizontal sections must have a minimum incline
of 3° upwards;
• e length of the horizontal sections must be as
short as possible, but without exceeding 3 m;
• More than four direction shis are forbidden,
including the cases where a T-shaped element is
used;
• e duct components must be airtight and to be
insulated if extending outside the premises in
which the replace is installed;
• e duct components must allow a soot cleaning;
• e duct components must have a constant sec-
tion. A section change is allowed only in the
chimney joint;

3.5 Air intake
Suction pipe or air intake is placed in the back and has a circular section with a diameter of 48 mm.
e combustion air can be aspirated:
• From the camera, as long as it is near an air intake communicating with the outside wall hav-
ing a minimum area of 100 cm2, properly positioned and protected by a grid.
• Or by connecting directly outside with a suitable tubing having an inner diameter of 48 mm
and a maximum length of 1.5 M.2
4. Cleaning
Cleaning the replace should be done only when cold. e cleaning of the combustion chamber
must be carried out daily. For this purpose, make sure the replace has ceased operation and is
completely cold. Pull up the combustion pot and remove it from the stove and then clean it from
soot. When removed fuel pot at the bottom of the combustion chamber opens a hole designed for
the accumulated ash. Collect ashes in the ashtray and return fuel pot in place and then close the
door. e replace is ready for operation.
Cleaning of ues and chimneys are conducted once every 1.5 tons of fuel used
Once clean audits and close the cleaning lid. Check that the bolts are tightened well. Every time
you open check for violations of the isolation seal. If this happens do not use the product until
the isolation seal is repaired.

5 Safety and unexpected risks
Terms of danger may arise in the following cases:
• Automated pellet stove is used incorrectly;
• e unit is installed by unqualied personnel;
• e safety instructions described in this management are not met;
Unforeseen risks:
Pellet replace “Mareli” has been designed and manufactured in accordance with the safety re-
quirements on the national, regional and European levels. Although considered possible risks
arising from improper use, you may experience the following risks:
• Risks of spreading combustion outside replace - opening the door of the chamber of the
replace may fall hot / burning particles (as hot ash and small particles burning coal), which
could lead to a re in the heated room. It is therefore necessary that the product always works
with a tightly closed door. It can only be opened when the product has completely cooled
down;
• Risks of burns caused by high temperatures as a result of the combustion process in the
combustion chamber and / or access to the door of this burn chamber when the product is
not completely cool;
In case of re hazard the product should be stopped by the controller and power supply until the
cause of the problem is determined.
