ATTENTION! STRICTLY RESPECT!
To protect against acid condense and to avoid the formation of tars
attacking the boiler’s body, it is mandatory to correctly assemble one of the
following equipment: 4 way valve or thermostatic mixing valve or
thermostatic control recirculation pump, (according to the fig.
”Installation scheme”, pg. 25-28.)
The boiler operating temperature must be in the range 70 – 90 °C,
while the minimal return temperature 60°C.
Use light color pellets as fuel (with minimum residues content) with
the maximum humidity of 12% and quality dry wood with the
maximum humidity of 25%.
When sizing the central heating boiler, you must take into account
the correct calculation of the heat needs, do not oversize the boiler!
The inobservance of the requirements above entails the
warranty loss!

Dear beneficiary,
Thank you for choosing FI-NSP BOILER ON SOLID FUEL – PELLETS, an innovating and
modern product, with special qualities and performances. This product provides maximum
satisfaction if you use the boiler according to the recommendations of this manual. We guarantee you
its long term use if the boiler’s putting into service is made by the authorized personnel of S.C.
TERMOFARC S.R.L.
The company provides you warranty and long term post warranty.
Many of us have the experience of heating up using fire wood or wood scrap briquettes in
the hot water boilers. It’s been a while since a new solid fuel appeared, the so-called pellets, an
ecological fuel manufactured in a similar way as the wood scrap briquettes, by pressing wood wastes
(wood scrap and wood chips),without any high pressure binders. The pellets have a cylindrical shape,
with a diameter of 6 – 10 mm and up to50 mm long, with a calorific efficiency of 4.8 - 5 kWh/kg.
Pellets are supplied in plastic bags of 15, 20, or 25 kg. Yet, in other countries, they are transported in
cisterns out of which the pellets are directly fed to tanks.
The benefit of such pellets is that they are ecological and that they may be used for heating
in central heating stations with automatic feeding.
Due to these reasons, our company executed this product, FI-NSP BOILER ON SOLID
FUEL – PELLETS made up of the pellets burner, the pellets tank with the feeding system and the
boiler type FI-NS already on the market for a long time.
This manual refers to the assembling, installation and use of the product. Thoroughly
studying the instructions, you shall get important information for the safe operation of this boiler,
thus obtaining optimum performances and long term use. To market them and for the product’s
compliance with the essential security requirements stipulated in the European Directives, the boilers
have been assessed by ISCIR CERT, consequently the compliance certificate 041B1 – 584/EC being
issued.

FI-NSP boilers are manufactured from steel sheet of 5 namely 6 mm in the inside part and 4 mm at
the external part, welded, made in eleven manufacture sizes.
From the construction point of view, they are boilers with water chamber, with chamber-type
burning point and two convective circuits of burned gases.
Their construction permits the use in two operating alternatives:
1. automatic operation, being endowed with automatic burners on pellets;
2. manual feed operation, using solid fuel (wood, coal, coke, wood scrap, wood wastes) in the
burning process;
They are meant for the heating of the buildings and the production of household hot water. They
are endowed with two heat exchangers: coil producing household hot water (the range FI-15NSP –
FI-50NSP), and cooling coil – protection against the overheating (all range of powers).
It may be assembled in a gravitational operation installation or in force circulation installation
with circulation pump;


Water chamber
: they are made up of two
plan-parallel walls of steel plate of 5 – 6 mm
width, namely 4 mm, located at a distance of
60 mm. The walls of the chambers are
reinforced with round steel cross-ties of Ø 10
mm welded at both ends. 

Boiler doors: allow the wood feed and the
cleaning of the pellets burner grate (the
middle one), the ash exhaust (the lower one)
and the cleaning of the convective routes (the
upper one). The door of the ash pan also plays
a part in the admission of combustion air by
means of a throttle, in the manual feeding
operation on solid fuel (wood, coal, coke,
wood scrap briquettes, wood wastes). The air
throttle is controlled by the draft
thermocontroller on the front part of the
boiler. It provides the closing of the throttle
and thus the reduction of the combustion
primary air feed when the temperature of the
water in the boiler reaches the set value.
The lateral door (the range FI - 80 NSP – FI –
150 NSP) allows the cleaning of the pellets
burner grate.
The back door represents the assembling
place of the burner on the pellets.

Convective system: as membrane walls of
pipes Ø 42 x 4.5 mm it provides two circuits
for the burnt gases, in which zigzag
turbulence nozzles are designed.

The grate: is plane, for the combustion
of the solid fuel in layer.
The ash pan: is a drawer that may be
taken out through the door in the lower part of
the boiler.

Heat insulation: it is executed of mineral
wool.
The coil for preparing household hot
water (the range FI-15NSP – FI-50NSP): is
made up of galvanized pipe of 1/2” and
inserted into the water chambers. The cold
water enters through the upper part at approx.
10°C and comes out through the lower part at
approx. 60°C.

The
cooling coil
: is made up of galvanized
pipe inserted in the water chambers; in the upper
part it is connected to the running water network
and in the lower part it is connected to the heat
valve, with an impurities filer interposing
between them. Its function is to cool the boiler in
case of overheating.
The control panel for automatic operation:
in the upper part of the boiler there is the
adjustment, safety and automation control panel
with the following component parts :
- Thermostat for controlling and adjusting the
boiler
- Safety thermostat (stops the pellets burner at
over-temperature whenever the first thermostat is
faulty – manual resetting)
- Thermo-manometer
- Led general switch
- Wire fuse 6 - 10A
The automatic pellets burner: made up of
the burner body, turboventilator, electric igniter,
control elements with programmable automaton
and photosensor.
Pellets feeding system: made up of pellets
tank (bunker), conveyor worm, engine and
reductor for the conveyor worm drive, feeding
tube, flexible tube.

Reinforcements: the following
reinforcements are located in the upper part of the
boiler:

Chapter 1
ASSEMBLING INSTRUCTIONS
This chapter addresses both to authorized persons proceeding to assembling the boiler, as well
as to the beneficiary who is interested in the executed works complying with the safety norms while
using all the elements contributing to the installation’s good operation.
The boiler may be assembled by companies or by ISCIR authorized personnel. The assembling
shall be executed on the grounds of a project, complying with the norms in force and with the boiler’s
technical book.
 Attention! If the boiler is not be assembled, store it in a dry place.
1.1. Choosing the boiler
The boiler must be chosen so that the rated power corresponds the heat losses and the heat
necessary according to STAS 1907, essential requirement for the accurate and economic operation.
Choosing a boiler with greater rated power shall result in tar deposits on its inside walls.
1.2. Location and position of the boiler
The boiler shall be assembled only in the heat power plants executed compliant with a project drafted by
specialized institutions, observing the safety measures stipulated in STAS 7132-86; STAS 3417-85 ; Norm I 13-
94; Norm I 13/1-96; PT C 9-2003; PT A2-2003; ISCIR collection; GP 051-2000; P 118-99.
The boiler shall be assembled in a separate room at the subsoil, basement or ground floor of the
civil or industrial buildings, except for those included in the A and B classes of inflammation or
explosion danger. As well, it is forbidden to assemble the boilers directly under rooms where
personnel cannot self-evacuate (such as the hospitals), under showrooms, stores, kindergartens or
under their access ways.
ASSEMBLING
LOCATION
The boilers room must be separate
from the adjacent rooms and have
sufficient windows. The room where
the boiler shall be assembled must be
large enough to allow the boiler
assembling on a perfectly even
surface. (Eventually on a metallic or
concrete base) respecting the
distances according to fig. 11. The
boiler shall not be assembled on
flammable material support. The
room must have a fresh air access
hole, with an opening of 400 cm2–
permanently open to the outside. We
recommend a siphon trap assembled
and drinking water pipes with
enough pressure to fill in the heat
plant installation.


 Attention! Locating the boiler in dwelling rooms and on the access halls is forbidden!
1.3. Assembling the boiler’s components
The boiler is delivered completely assembled and equipped. If you encounter problems when
moving it to its operating place, the components may be disassembled as it follows, according to
blueprint in fig. 12. When disassembling it, start by removing the cover. Then remove the lateral
covers by unscrewing the M6stud bolts located two in the upper part and two in the lower lateral part.
If necessary, you my also disassemble the back cover by unscrewing the M6stud bolts, then the three
smaller components (between doors) shall be removed if you unscrew the stud bolts M6.
When the boiler is located where it is meant to operate, before assembling it, we proceed to its
dressing up. The component parts shall be assembled according to the blueprint in fig.12. The
assembling starts by fixing the back cover by means of the M6 stud bolts. Then, the three smaller
components (between doors) shall be fixed using the M6 stud bolts. Then, the two lateral covers shall
be fixed using the stud bolts M6, two in the upper part and two in the lower lateral part. When
assembling the top cover, the probes and the inlets of the control device shall the inserted in the
corresponding case and in the coupling inlet ¼”.
