3. OPERATION INSTRUCTIONS
3.1. OVERALL CHARACTERISTICS OF HOT WATER BOILER
FROM BISOLID COMFORT SERIES
The solid fuel boilers from BiSolid Comfort 03/04/05 series are designed for heating of
domestic and industrial buildings.
Preconditions for proper functioning of the hot water boiler are not only its professional
installation, but also the needed chimney draught and its correct operation.
The solid fuel hot water boiler from Bisolid Comfort series is designated for heating systems
which are suitable for systems with forced water circulations.
The hot water boilers from series BiSolid Comfort are offered in three output models (defined
by the number of sections: 3, 4 and 5) with heating capacity from 18 to 32 kW.
The cast-iron boiler body consists of sections and serves as combustion chamber (including
for flue gas extraction) and in the same time as water heat-exchanger. There are three types
of sections - integrated front and rear and from 1 to 3 middle sections (same type), which are
between them. The boiler body required size is built during the assembly (combustion
chamber and water heat-exchanger), with a suitable number of sections. The assembled
boiler body is equipped with the necessary pipe elements for connecting to the water-supply
system.
The boiler body is also equipped with brackets for installation of thermostat sensors and
brackets on the legs for fixing the boiler to a floor base. Steel plate covers are mounted on the
boiler body and are filled inside with heat-isolation.
In order to guarantee the boiler’s proper operation and that it will operate economically, it is
important to know that its nominal heating output is equal to the heat losses of the heated
premises.
Choosing a boiler with insufficient heating output will lead to unadequate heating of the
premises and by such terms not providing of the heating comfort.
Choosing a boiler with unnecessarily high heating output will lead to terms in which the boiler
will not operate at its full ouput power and as consequences to excesive condensation and tar
deposits.
3.2. SAFETY AND CONTROL DEVICES
The hot water solid fuel boilers from series BiSolid Comfort 03/04/05 are equipped with two
main control components:
Chimney (flue) flap.
Thermo-regulating valve (TRV).
The chimney flap (Figure 3) is element which supports the chimney draught regulation, i.e.
exctracting the flue gasses to the chimney. The flap is situated in the boiler’s flue back side
and is controlled manually.

Danger
When installing the elements for safety and control please do not forget that all
installation works must comply with the safety labor principles. If thermoregulation valve or other safety element replacement is necessary, please use
the recommended devices. In case of using any other type of devices you
should ask the supplier first. The thermo-regulating valve must be checked by
authorized specialist once per year.
The change of the flap position controls the burning intensity and by that the boiler heating
output (when operating with wood logs). The thermo-regulating valve is connected to the
control flap by a chain. The chain is connected to the flap in such way that the thermoregulating valve tensioning can be adjusted (Figure 5).
Figure 5. Control flap.
Warning
When the boiler operates with wood pellets the chain must be disconnected
from the flap. The necessary air for firing is supplied by the pellet burner fresh
air fan.
Danger
Keep any objects away from the regulating flap and from the grooves providing
primary air intake.
The hot water temperature can be measured by thermometer (Figure 6), which is situated on
the front boiler panel, over the fuel feeding door.

4. BOILER INITIALIZATION TO OPERATION
4.1. BOILER CHECK-UPS BEFORE INITIALIZATION FOR
OPERATION
Before initializing the boiler for operation the service technician must check:
If the installation complies with the project.
Boiler must be filled with water, to be under pressure and to check the entire heating
system for leakages.
Boiler connection to chimney – flue pipe connection lines must be approved by
authorized service technician.
Heating regulators functionality.
Warning
The service technician must train the user how to operate and manage the
boiler and also to fill in the exact start of operation date in the warranty card of
the product.
4.2. FILLING AND DRAINING THE HEATING SYSTEM
The system can be filled or drained with water only if the water corresponds to EN standards
values. The water must be clean, with no color, no suspended particulates, oils and chemically
aggressive and corrosive substances, and also it should not be acid (pH factor must be higher
than 7.0). At first place a comprehensive rinsing of the entire heating system should be
performed.
Warning
Water quantity in the system should not be decreased or drained except in the
cases when the boiler is being repaired or there is risk of freezing. An antifreeze
fluid can be added against freezing, with a volume of 15% from the total liquid
quantity (please see the anti-freezing fluid supplier usage instructions).
Warning
Not fulfilling the above mentioned requirement might result in clogging the heatexchanger of the boiler and cracking the cast-iron sections. During the heating
season the water volume in the heating system must be kept constant. If
refilling with water you must be careful to not intake air into the system. The
circulation water should never be drained out from the boiler or the heating
system, except if it is absolutely necessary, for example when doing repairs and
etc. Draining and refilling the system with water increases the risk of corrosion
and boiling stone (scale).
Warning
Filling or topping up water into the heating system must be done only when the
boiler is cold or cooled, in other case the cast-iron sections of the boiler may
crack.

5. BOILER OPERATION AND CONTROL WITH WOOD LOGS
5.1. BOILER FIRING
Before firing a hot water boiler from BiSolid Comfort 03/04/05 series check the manometer and
wether there is enough water in the heating system. Open the stopping valve, located between
the boiler and the heating system. Spread paper over the cleaned fire-grate and then put over
it enough quantity of chopped wood pieces. Open the flue flap and close the fuel feeding door.
Ignite the paper through the ash cleaning door and fully open the regulating flap, located on
the same door. When the fire has ignited enough layer of the main fuel, a smooth burning
should be observed. When the fire has enough power, add more fuel up to the lower edge of
the fuel feeding door.
Ensure equal layer of fuel on the whole boiler depth. When the boiler has reached the needed
heating output, then it is necessary to part or half close the chimney flap, in order ro prevent
exctraction of heat to the chimney.
Danger
Do not start the boiler if it’s not connected to a chimney.
Before starting the boiler check its connection with the chimney.
Check the chimney draught. If it is above the recommended values a
draught regulator has to be installed.
5.2. HEATING WATER TEMPERATURE ADJUSTMENT
When the desired heating water temperature is 60°C, you can heat the water in the boiler for
example with 5°C higher than the desired temperature of 60°C (it is measured by the boiler
thermometer). This is possible if you turn the thermo-regulating valve’s head to 65°C and
check if the regulating chain is streched and the regulating flap is completely closed. This
position of the flap regulating chain can be adjusted by turning the regulating valve’s head.
Then the process of adjustment works out. When the water temperature decreases, the
regulating flap will start to open by the force applied from the chain. When the water
temperature suddenly increases, the regulating flap will start to close. In such way the air fed
in the burning zone can be regulated, respectively the water temperature in the boiler.
5.3. REFUELING THE BOILER
First close the regulating flap, this action will cut the air supply needed for firing in the boiler.
After that, open the chimney (flue) flap completely. Gradually open the fuel feeding door and
wait until all gasses are led out from the burning chamber to the chimney. Only then you can
open the fuel feeding door completely and start to refuel the boiler. After closing the fuel
feeding door, you should again restore the chimney flap position and the regulating flap
function.
Danger
Boiler doors must not be opened when it operates continuously.
When refueling the boiler ensure minimum distance of 5 cm between the
loaded fuel highest point and the combustion chamber top surface.
Page 18
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
BiSolid Comfort OM-BSCV00/08/2012/EN
18
5.4. BOILER HEATING MODE DURING THE NIGHT
This mode is used when you want to keep the fire in the boiler burning, for example during the
night. First scrape all the ash from the combustion chamber, with completely opened chimney
flap. After that refuel the boiler and close the fuel feeding door. After that, close the chimney
and the regulating flaps. This will lead to chimney draught decreasing and will limit the firing air
supply. Then close the rosset for secondary air supply. To restore the needed boiler heating
ouput open the chimney flap and partially open the regulating flap, until reaching the needed
boiler heating output.
5.5. CLEANING THE ASH
The cleaning is performed by removing and emptying the ash-tray, positioned in the ash
drawer under the fire-grate. This action must be performed regularly, in order to prevent ash
depositing and blocking the air supply to the combustion chamber.
5.6. CONDENSATION AND TARS
When firing a cold boiler the water condenses over the walls and flows down in the ash
drawer, which causes doubt that the boiler “leaks”. The condensation will disappear when the
inside walls of the boiler get warmed. When the boiler operates with low water temperature,
usually under 65°C or when the used fuel is wet, then the water condenses in the flue gasses
and the condense leaks down over the cold boiler walls. The low temperature heating mode
reduces the chimney life-time also. Therefore it is recommended to equip the boiler with fourway mixing valve, which guarantees that the inlet water will not be below 50°C. The tar
depositing occurs in similar conditions (lack of air for firing, boiler clogging). To prevent from
condensation and tars we recommend to start the boiler at water temperatures higher than
65°C or to choose a boiler which corresponds to the needed heating output. The oversized
boiler operates inefficiently, because it has to operate at low temperatures.
Warning
Condensation is possible at initial boiler firing. This should not embarrass the
user, because it is normal event – especially when firing wood with higher water
content. The boiler “dries” when it reaches normal operation mode.
5.7. BOILER SWITCH OFF
We do not recommend you to accelerate the burning process in the boiler. The fuel must burn
completely by itself over the fire-grate.
5.8. BOILER SHORT-TERM SWITCH OFF
After switching off the boiler, clean it, take out all burned wastes, empty its ash-tray, clean the
contact surfaces of the feeding door and the ash drawer, and after that close the boiler’s fuel
feeding and ash drawer doors.
Page 19
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
BiSolid Comfort OM-BSCV00/08/2012/EN
19
5.9. BOILER LONG-TERM SWITCH OFF
When switching the boiler off for long period of time (at the end of the heating season), it must
be completely cleaned from all unburned accumulations (soot, ash and deposits). Otherwise
the accumulation of moisture in the unburned gasses leads to excessive boiler corrosion.
Warning
The boiler can be operated only by adult people who are well introduced with the
current manual for operation.
Switch off the boiler every time when there is any (even momentary) danger by the
presence of flammable or explosive vapors situated in the same room from which
the boiler intakes air for burning (for example painting paint, spraying or laying
molten substances, gas leakage, etc.).
Boiler initial firing with explosive substances is strictly forbidden.
Boiler overheating is forbidden.
The boiler and the chimney have to be completely cleaned at the end of the heating
season. Also grease all hinges, chimney flap mechanism and other moving parts.
5.10. BOILER MAINTENANCE
Maintenance of the boilers from series BiSolid Comfort 03/04/05 has to be performed daily,
periodically or early.
During the daily maintenance the user must clean the unburned residues in the combustion
chamber, to clean the ash gathered in the combustion chamber and to dump the ash from the
drawer.
It is important that the user performs periodical maintenance of the appliances, in order to
achieve effective usage, prevention of possible problems with its operation and optimum boiler
life cycle. We recommend periodical check on every 3 months. Such checks have to be
performed by authorized servicing technicians and should include the following activities:
Check boiler’s combustion chamber and flue pipe, including the chimney. They should
be cleaned if necessary.
Check for leakages of incoming or outgoing water, in and out of the boiler, water pipe
links as well.
Check valves, fittings and accessories.
Check circulation pumps.
Visual check of the fire-grate.
Perform operation control check for safety of the hydraulic system and the boiler.
The yearly maintenance (prophylaxis) of the boiler must be performed only by authorized
technicians, before the start of the heating season. Before calling the servicing technicians the
user has to provide already cleaned flue pipes and chimney. During the yearly prophylaxis the
authorized technicians perform the following checks and activities:
Position of the combustion chamber shaft, isolation and isolation ropes.
Boiler test at operating pressure for adjustment of the burning, by measuring flue gas
parameters if necessary.
Check and clean the boiler’s fire-grate and surfaces from soot and ash.
Test boiler connections for leakages.
Check fittings including muffs, mixing valves, pressure valves for reliability.

Test and if necessary clean the water filter.
Check expansion tank (buffer) and clean it if necessary.
Test pressure sensor. Clean or replace it if necessary.
Perform operation control check for safety of the hydraulic system and the boiler.
5.11. BOILER CLEANING
After continues operation of the boiler amounts of soot and ash accumulate to its walls, mainly
over the heat-exchanger sections and the flue outlet, which decrease the heat-exchanging
rate and the boiler heating ouput. The amounts of soot and tar depend on the operation
conditions and the types of used fuel. This may also lead to inadequate chimney draught.
Boiler cleaning has to be performed regularly, at least once per month, usually by using steel
brush through opened boiler door.
All inside walls of the boiler in the combustion chamber and the flue gasses passage channels
must be cleaned. If there is bigger quantity of tars over the combustion chamber inside walls,
then it must be removed by using a scraper or burned by firing hard wood at maximum
operation temperature.
Direction
The ash must be stored (the ash has to be taken out by using gloves) in
fireproof reliable containers and to be transported to opened spaces. Other
garbage or wastes should not be stored in these containers.
5.12. BOILER REPAIR
The boiler must be repaired only by authorized servicing technician or servicing organization.
The user or owner is allowed to perform only normal maintenance and to replace only a few
parts, for example sealing of insulating rope.
Warning
Always use only genuine spare parts when repairing the boiler.

7. BOILER INSTALLATION INSTRUCTIONS
7.1. BOILER INSTALLATION – OVERAL INFORMATION
The hot water boilers from series BiSolid Comfort 03/04/05 must be initianted into operation by
authorized servicing technicians. The existing network of authorized servicing organizations
which comply with this condition is able to take responsibility for all boiler installations, their
initialization in operation and warranty repairs.
The boiler is designed to supply heating systems with pressure up to 400 kPa by using water,
which must compy to the standard requirements (under no circumstances the water can be
acidic, i.e. it must have hydrogen exponent pH>7 and minimum carbon hardness). The heating
system must be designed in such way that the hot water circulates at least through some of
the radiators at all times.
We do not recommend the usage of antifreeze liquids because of their unsuitable properties.
Such liquids have decreased heat-exchanging capabilities, high volume expansion and
harmfull components.
Before final installation, the distribution pipelines of the heating system must be rinsed several
times with water under pressure. In old, already used systems, the rinsing has to be performed
in opposite direction to the heated water circulation. In new systems all radiators have to be
cleaned from erosive materials and rinsed with warm water under pressure.
We recommend installation of precipitant on the boiler entrance (i.e. on the boiler’s hot water
return pipeline). The precipitant should be designed with availability for emptying on regular
intervals, without necessity of draining too much hot water. The precipitant can be combined
with filter, but the filter itself is not enough to secure adequate protection.
Warning
The system must be connected to open type expansion tank, for safety
reasons.
Any of the stopping fittings must not be connected to the inlet or the safety
outlet pipelines.
For increasing the system safety a bypass line must be installed on the inlet
and outlet line of the circulations pump, as presented on the diagrams.
The bypass line valve must be closed when the boiler operates normally.
The bypass line valve can be used when there are problems with the power
supply and must be opened if there is any risk of heating system water
overheating, caused by power supply failure or another problem.
The pipelines diameter installed in the bypass line must be at least equal of the
water supply pipeline.
UPS (uninterruptible power supply) can be used for prevention of power supply
failures.
Warning
All problems (faults) with the boiler caused by clogging with dirt from the heating
system or faults caused by clogging are not covered by the product warranty.
Page 30
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
BiSolid Comfort OM-BSCV00/08/2012/EN
30
Warning
The filter, as well as the precipitant must be checked and cleaned regularly.
7.2. BOILER WATER REQUIREMENTS
The boiler water requirements are presented in the European standards. If the sum of calcium
and magnesium content in the water exceeds 1,8 mmol/l without additional chemical
processing, then for calcareous depostis prevention special measures must be performed (for
example processing with magnetic or electrostatic field).
7.3. BOILER POSITIONING
The hot water boilers from series BiSolid Comfort 03/04/05 can be positioned in rooms that
comply with the acting legal local provisions. The boiler room must have constant fresh air
intake, needed for the burning process. The air has to be clean, without halogen
hydrocarbons, corrosive vapors and should not be too wet and dusty. The room must be
protected against freezing and with no more than 80% relative humidity of the air.
In order to comply with the fire provisions the boiler must be installed:
Over flooring from inflammable material.
Over surface from inflammable material, under-covering the boiler with 20 mm pitch
from every side and covering the entire width of the boiler body.
If the boiler is installed in the basement, we recommend that it is positioned over
fundament with at least 50 mm height, as the boiler is positioned in the middle.
In compliance with the servicing standards it is necessary to leave space with at least 600 mm
length at the boiler front side. The minimum distance between the boiler back and the wall
must be also 600 mm. It is also necessary to leave free space of at least 600 mm between the
boiler sides and the wall, in order to provide access to the boiler back side. The fuel must not
be positioned close to the boiler, as the minimum distance is at least 800 mm.
If there are two boilers in the room it is not allowed to position any fuel between them. It is
recommended to keep minimum distance of 800 mm between the boiler and the fuel (Figure
12), or to store the fuel in a premise different from the boiler room.
Danger
Do not put flammable materials over the boiler’s top side or near it within the
safety distance.

7.5. POSITIONING IN THE BOILER ROOM
Figure 13 presents the minimum distances which must be observed in order to guarantee safe
operation in the boiler room and availability to perform servicing, cleaning and refueling.
The distance between the boiler front side and the wall has to be at least the boiler length plus
500 mm.
The minimum distances between the boiler from back and side have to be 800 mm, as the
distance in the back is determined by how the boiler is connected to the chimney.

Figure 13. Minimum distances in the boiler room.
Danger
When the boiler operates do not touch any hot water pipe lines or flue pipes.
7.6. INSTALLATION PROCEDURE
Position the boiler over inflammable material surface.
Install the temperature safety valve. During its installation make sure that the arrow
direction shows the water flow direction.
After connecting the boiler to the heating system screw the boiler’s filling and draining
stop cocks at its back side.
Install the flue pipe with the boiler’s flue flap for extracting the flue gasses.
Place the flue pipeline end in the chimney connection orifice. The boiler flue diameter
is 150 mm.
Mount the thermo-regulating valve in the orifice at the front section top side.
We recommend installation of hot water stopping valves at the inlet and outlet pipes,
before draining the entire heating system, so they can clean before the filter.
Any stop fittings should be installed between the boiler and the expansion tank.

7.8. BOILER OPERATION WITH ACCUMULATING TANK
In some cases the heat energy can be delivered to the consuming devices by accumulating
tank. The formula for determining the minimum needed water quantity for accumulation tank is
given below.
Vsp – Volume of the accumulation tank, litters.
QN - Nominal heating output, kW.
Tb - Burning time, h.
QH - Premises heating load, kW.
Q
min
– Minimum heating output, kW.
The heating boiler, which uses not only one fuel type, should operate with accumulation tank,
dimensioned in compliance with the used fuel type requiring highest accumulation tank
volume. Usage of accumulation tank is not necessary when the defined volume is lower than
300 litres.
7.9. TRANSPORTATION AND STORAGE
The boilers for expedition are offered by the manufacturer on a wooden pallet and secured
against moving with cap bolts. The boilers should not be transported in position different from
their base (normal operating position).
It is necessary to ensure at least the minimum conditions for preservation of the boilers during
their storage and transportation.
During transportation and storage the boilers packages and cover panels should not be
pressed.
Danger
The boilers should not be moved or transported without using forklifts, transport
carts or other wheel based transport utilities.

7.10. FLUE OUTLET PIPELINE INSTALLATION
Figure 17 presents the correct connecting of the boiler flue pipeline to the chimney, by
additional pipe connection. Please observe the following rules when installing the flue
pipelines to the chimney:
Install the flue pipelines (pipe connection) to the chimney by checking the cleaning
manhole.
Fix the pipeline to the boiler flue outlet.
Install the flue gasses pipe to the chimney, by using the shortest track, without using
excessive number of bends. Avoid undesirable coupling sections, especially with 90 °
connection angle.
Fix the pipelines reliably by using enough number of supports (especially for long flue
pipelines).
The flue pipeline (pipe connection) must be installed carefully in order not to loosen,
because it is fixed only to the chimney inlet.
Use parts and components for connecting the boiler flue outlet to the chimney that are
made only from inflammable materials.

7.11. CHIMNEYS AND ADVICES FOR CONNECTING TO
CHIMNEYS
It is enough to have a drawing for connecting the boiler flue outlet to the chimney, as main
condition for the boiler correct functioning. This requirement is essential and determines the
efficiency and correct operation of the system. Therefore the following features should be
noticed when connecting the boiler flue outlet to the chimney:
Page 38
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
BiSolid Comfort OM-BSCV00/08/2012/EN
38
Have in mind that the boiler must be connected to the chimney system (to flue gasses)
in accordance to the local legal conditions.
When connecting the boiler to the chimney it is necessary to ask professional installer
for consultation and installation, because all activities must conform to the regulations
for installation and the manufacturer instructions.
The boiler can be correctly connected to the chimney by using a chimney system
project and technical specification.
The chimney system design sizing (flue gas pipelines system) must be based on the
flue gasses mass flow rate, at maximum heating output of the boiler.
The effective height of flue gas chimney is determined by the coupling point of the
boiler flue outlet to the chimney.
Make sure that the chimney system sizing and the flue connection to the chimney is
performed by qualified specialist.
If the boiler is not connected properly to the chimney, the product warranty will be
considered as invalid.
The presented dimensions in Figure 18 are only tentative. The operation scheme depends on
the diameter, height, chimney wall roughness and temperature difference between the
combustion products and the outside air temperature. We recommend the usage of chimney
with integrated metal insert.
Usually for more accurate calculations, performed by heating specialist or installer of the
chimney system, the below formula is used for determining the chimney cross-section area.
F - Chimney cross-section area, cm2.
a – Coefficient (а = 0.041 for wood logs).
QN – Boiler heating outlet, kCal/h.
H – Chimney height, m
