INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Wood pellets must be stored in dry premises, so they can be transported without problems
and also in order to achieve trouble-free operation with optimum combustion and maximum
efficiency. The preferred fuel (wood pallets) should be stored in dry premises, so that it can be
transported without problems thus enabling trouble-free operation with optimum combustion
and maximum efficiency.

Boilers series Bisolid Automat can utilize firewood as other suitable fuel with maximum
humidity 25%, i.e. in the form of chopped firewood logs with diameter up to100 mm and length
400 mm, split firewood with bark or without bark. The manufacturer recommends that the fuel
be applied transversely in the fuel hopper, so as to achieve gradual combustion and fuel
layering.

Boilers series Bisolid Automat can also utilize as other suitable fuel wood chips as well with
maximum moisture of 40%.

When using firewood or wood chips with irregular or non-compliant form, additional control
should be exercised on the boiler by the service personnel.

Supply of fresh air to the combustion chamber of the boiler through the tube
pellet burner fan, which is automatically activated, allowing for burning of fire
wood and wood chips with higher moisture.

The mounted to the heating boiler Bisolid Automat pellet burner with rotary self­cleaning Bisolid GP xx R tsc is designed for burning of the approved by the
boiler manufacturer solid fuels ONLY!

Hot water boilers series Bisolid Automat are not designed to burn coal.

2.4. DESCRIPTION OF THE BOILER

The boiler is a welded construction of steel sheet panels and pipes. The inside space is
separated by water baffle into a fuel hopper, combustion chamber and heat-exchanger,
through which the flue gases are discharged to the chimney neck. A movable two-component
grate is located under the combustion chamber and the fuel hopper, which is run laterally
using a lever.

The combustion air is supplied by a fan, located in the pellet burner of the boiler, controlled by
an electronic device.

Heating water inlet and outlet are secured by nozzles G1
backside of the boiler along its axis. The exhaust gases (flue gases) discharge valve is
controlled from the top of the boiler. The exhaust gases discharge flap (flue gases evacuation
flap) serves to evacuate the flue gases during loading the fuel hopper of the boiler. The flap
opens during loading other suitable fuel (firewood and wood chips) into the fuel hopper of the
boiler and closes immediately thereafter.

Not opening the flue gases flap may result in a smoke in the boiler fuel hopper during loading
other suitable fuel.

The flue gas discharge flap (flue gases evacuation flap) should be opened only
during loading the boiler hopper with other suitable fuel. The flap should be
closed immediately after closing the door of the fuel hopper.

4. OPERATION INSTRUCTIONS

4.1. OPERATION OF BOILER BISOLD AUTOMAT

The boiler should be maintained only by adult persons, preliminary acquainted with the boiler
operation and maintenance. The boiler service and maintenance personnel should strictly
comply with the manual and should only commission the boiler, adjust the temperature of the
thermal power regulator, decommission the boiler and conduct ongoing monitoring of ts
operation. After commissioning the boiler, the service technician should acquaint the user with
the boiler operation and maintenance. Unattended children are not allowed near the boiler.
Any activity on the construction of the boiler, which might endanger the life and health of the
maintenance personnel or of persons present in the boiler room, is strictly forbidden.

The boiler should be operated at a maximum water temperature of 90 oC and is subject to
ongoing control. Use of flammable liquids for easy firing as well as any activities related to
increasing boiler rated power (overloading) are strictly forbidden. Positioning of flammable
objects on top or near the boiler is not allowed. The ash should be taken out in fireproof
container with cover.

In case of danger from penetration of flammable vapors or gases in the boiler
room or any activities that might lead to fire or explosion (bonding flooring,
varnishing with flammable paints or others), the boiler should be
decommissioned before starting any of these activities.

4.2. SAFETY OPERATION OF THE BOILER

Relevant safety instructions should be observed when operating the boiler. Bisolid Automat
Boiler should not be used for any other purposes except for those indicated in this manual.

When operating the boiler Bisolid Automat, always a heating circuit has to be

included in which the water is circulated. If the heating radiators are equipped

with thermostatic valves (or other control components), which close the

circulations water flow. As a result of this process it is possible that the

generated heat energy, from the fuel final combustion, can’t be adopted by the

heating system (can’t be unloaded) and to lead to overheating of the appliance.

Therefore in case the boiler Bisolid Automat is operated in heating systems with

radiator regulation valves, it is necessary not to completely close the radiator

valves, but to adjust them to minimum value. Also one of the radiators should

not be equipped with regulation valve, in order to ensure adoption of the heat

energy generated during the process of final combustion.

Boiler surface should be cleaned only with standard inflammable cleaners. Positioning of
objects made of flammable materials near the boiler at an unsafe distance is not allowed.

It is not allowed to store flammable materials (wood, paper, oil, diesel oil, petrol and other
readily flammable materials) in the boiler room. The minimum allowed distance between
boiler’s outer parts and the flue pipe and any average or not readily flammable materials
(which dye out after firing without any additional heat energy), should be not less than 100
mm.

The allowed distance from readily flammable materials (which continue to burn after removal
of the firing source) should be minimum 200 mm.

Bisolid Automat OM-BAV05/02/2018/EN 32

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Removal of solid waste, combustion process products, out of the ash tray should be
performed using the ash box. The ash box (ash tray) should be emptied in good time before
fully filled. All ash box related activities should be performed using a handle, situated on its
front. After removing the box from the boiler the ash should be dumped in a preliminary
prepared fireproof container. When handling or operating use gloves as protective equipment.

When installing the boiler and its safety and control components, do not forget
that all installation works should comply with the safety at work principles.

Bisolid Automat OM-BAV05/02/2018/EN 33

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

5. BOILER BISOLID AUTOMAT COMMISSIONING

5.1. BOILER INSPECTION BEFORE COMMISSIONING

Before commissioning the boiler, the service technician should check:

 Whether the installation comply with the design.
 Whether the boiler is filled with water and under pressure and weather there are

leakages in the heating system.

 The connection of the pellet tube burner to the boiler.
 Boiler connection to the chimney – the pipe connection should be approved by an

authorised service specialist.

 Functioning of the heating regulators.

The service technician should train the user how to control the boiler and
should fill-in the exact date of commissioning the boiler in the warranty card.

When installing a Bisolid Automat boiler on the heating system always observe

the requirements indicated in section 9.5 for the installation of the boiler

equipment excess heat release.

5.2. EXEMPLARY PRINCIPAL HYDRAULIC SCHEME

5.3. FILLING AND DRAINING THE HEATING SYSTEM

The system may be filled with water or drained only if the water corresponds to the parameters
of the EN standards. The water should be clean, colorless, without suspended particles, oils
and chemically corrosive substances, and it should not be acidic (рН factor must be higher
than 7.0). First of all a comprehensive washing of the entire heating system should be
performed.

Water amount in the system should not be decreased or drained except in the
cases when the boiler is being repaired and there is risk of freezing. An
antifreeze fluid can be added into the water system representing 15% of the
total water quantity (see anti-freezing fluid instructions of the supplier).

Non-fulfillment of the above mentioned instruction might result in clogging the

heat-exchanger. During the heating season the water volume in the heating
system should be kept constant. When topping up water, be careful and avoid
intake of air into the system. Water should never be drained out of the boiler
or the heating system, except if it is absolutely necessary, like during repair and

other. Draining and refilling the system with water increases the risk of
corrosion and boiling stone (scale).

5.4. CONDENSATION AND TARS

In boiler initial commissioning the walls of the boiler condensates, which drains into the
combustion chamber. Such condensation on the walls might cause doubt that the boiler

“

leaks”. The condensation disappears after depositing of ash on the inside walls, which is
usually achieved after 2 to 4 ignitions. When operating at reduced power, at low water
temperature in the boiler and low flue gas temperature, condensation forms on the inside

Bisolid Automat OM-BAV05/02/2018/EN 35

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

boiler walls, which drains into the combustion chamber. As the flue gas condensation point is

o

65

C, the condensation forms only when the gases cool down in the middle layer of the boiler
walls, where the temperature is lower than 65 oC. If condensation affects the combustion
chamber as well, this means that the used fuel is too wet. In such a case, the condensate may
leak into the combustion chamber even if the water temperature is higher than 65oC. Tar forms
under similar conditions - low thermal power, low temperature and in case of improper
regulation of the combustion process (insufficient amount of secondary air).

The tar is removed from the walls of the boiler using the provided tar scraper, but only when
soft. This can be achieved at boiler water temperature around 90 oC. Such temperature,
however, quickly takes the heaters out of their nominal mode of operation. Therefore, quickly
burning soft firewood is recommended as optimum fuel.

If you decide to install an expansion tank to prolong boiler life, before that

eliminate the possibility of low temperature corrosion along the fuel pass by

maintaining boiler temperature above the dew point of 65 oC. This can be
achieved by a mixing device. If low temperature corrosion is not limited, the
boiler corrodes while the expansion tank, in most of the cases, reduces the life
of the boiler body as a result of the pressure and the dynamic load on the boiler
walls. Only service providers, duly authorized to perform such activities, have
the right to install expansion tanks.

At boiler initial firing condensation may occur. This should not trouble the user
as this is normal - especially when burning firewood with higher moisture. The
boiler "dries" when reaching normal mode of operation.

5.5. BOILER MAINTENANCE

The combustion grate is cleaned by moving the lever forward and backward in a range of 10­15 cm by lifting the control lever. If you want to do a thorough cleaning after completion of the
combustion process, the grate is drawn fully forward with the help of the lever of the grate.

The boiler should be used only up to its rated thermal power. Overheating the boiler results in
limiting the life of the heat source, this is not recommended by the manufacturer. The boiler
and the heating system should be dimensioned so that to avoid continuous operation with inlet
water temperature of less than 65 oC - the dew point.

If the boiler works continuously in this mode of operation, its lifetime is reduced, resulting in
heavy contamination and tar smearing on the boiler and the chimney, which results in limited
chimney draft and creates other preconditions to degrade performance? For this purpose, we
recommend during transitional seasons (spring, autumn) to fire the boiler for a short period of
time at full thermal power, in order to burn the deposits and to dry the chimney.

The manufacturer does not recommend, under no circumstances, to burn

sawdust, which significantly reduce the lifetime of the boiler.

Bisolid Automat OM-BAV05/02/2018/EN 36

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

5.6. BOILER CLEANING AND MAINTENANCE

After continues operation, soot and ash accumulate on the boiler walls, which reduces the
performance of the equipment. The quantity of soot and the eventual tar depend on the
operation of the boiler, the type of fuel used, the parameters of the chimney draft and the
outlet water temperature. Cleaning of the boiler should be carried out according to need and
operating conditions, but at least once a week.

After stopping its operation, the ash from the grate should be cleaned. The smoke damper is
adjusted in the upper position and the heat-exchanger cover is taken off. Cleaning of the heat­exchanger is done with the cleaning tools provided with the boiler (steel scraper and brush).
The soot fallen under the heat-exchanger is removed through the soot door. After cleaning the
boiler, the ash door is returned to its initial position.

During cleaning, it is recommended to check the condition of the ceramic blocks in the
combustion chamber. Damaged blocks are replaced with new ones.

Please strongly concider the timely closing of the flue gases flap of the boiler.

The ash must be stored (the ash has to be taken out by using appropriate
gloves) in fireproof reliable containers and to be transported to open space.
Other waste should not be stored in this container.

Maintenance of boilers series Bisolid Automat is done daily, periodically or annually.

In daily maintenance, the user must clean the unburned residues in the combustion chamber;
clean the ash gathered in the combustion chamber and dumps the ash-box (ash-tray).

For effective use, to prevent possible problems with the operation and for optimum life of the
boiler, it is very important that the user performs periodic maintenance of the equipment. A
periodical check on every 3 months is recommended. Such checks should be performed by
authorized service 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 inlet - outlet water, in and out of the boiler and water pipe

connections.

 Check fittings including valves and flaps.
 Check the fresh air fan of the pellet burner.
 Check the circulation pimps.
 Visual check of the grate.
 Operation and safety control checks of the boiler hydraulic system.
 Check the unloading valve.

The annual preventive maintenance of the boiler should be carried out only by authorized
technicians, before the start of the heating season. Before calling the service technicians the
user should clean the flue pipe and the chimney. The annual preventive maintenance carried
out by authorized service technicians includes the following checks and activities:

 Position of the fuel hopper and the combustion chamber, insulation and insulation

ropes.

 Boiler testing at operating pressure for adjustment of combustion by measuring flue

gas parameters if needed.

 Checking and cleaning the boiler grate and surfaces from soot and ash.

(WOOD PELLETS)

6.1. PURPOSE OF THE TUBE PELLET BURNER

The purpose of the fully automated tube pellet burner with manual cleaning Bisolid GP xx R
tsc as part of the accessories of Bisolid Automat series boiler is to heat sites with small and
medium sizes.

The pellet tube burner is a very good heating solution by burning wood pallets. What is more,
pellet burner Bisolid GP xx R tsc may automatically fire other suitable fuel, used by the user,
like firewood and wood chips, then stop and subsequently, if the boiler other suitable fuel has
been burned out to start automatically burn wood pellets.

The automatic electric ignition, the automatic selection of the thermal power (optimization
mode with room thermostat) and the multi-functional indicator control panel of the pellet tube
burner make it easy and comfortable to use during the heating season.

Pellet burner Bisolid GP xx R tsc is designed to burn wood pallets compliant with standard EN
ISO 17225-2:2014, classes A1, A2 and B with the relevant quality characteristics that are
shown in Table 1 and Table 2. The fuel and air mix in the burner in a controlled way result in
an ecological highly efficient combustion.

The required minimum time for maintenance of tube pellet burner Bisolid GP xx R tsc,
depending on the characteristics and the quality of the wood pellets, is once a week.

The optimum functionality of the equipment depends both on the professionally designed
heating installation and on the precise maintenance of the pellet tube burner.

6.2. PURPOSE OF THE PELLET BURNER CONTROLLER

The controller is designed to provide automatic control of the combustion process and to
adjust the power of the pellet burner, depending on the heating needs of the building or the
premises.

Hot water boilers series Bisolid Automat are designed to work with preferred
fuel (wood pellets) and other suitable fuel (firewood and wood chips). The
working algorithm requires the presence of pellets because the ignition of the
other sitable fuel and optimal burning is assisted by the pellet burner operation.
In principle, it is possible work only with pellets, but the optimal use of the
opportunities of boilers, and heat output becomes both fuels.

It is forbidden directly ignition of hot water boilers series Bisolid Automat using
other suitable fuel (firewood or wood chips) without to be switch on the pellet
burner controller!

Switch on the pellet burner controller before starting operation of the
boiler!

The device can control the following system modules of the pellet burner:

 Fuel feed auger 1.
 Fuel feed auger 2.
 Fresh air fan and flue gases fan.
 Electric heater to ignite the pellets.
 Cleaner to clean ash.
 Boiler circulation pump.

At primary switch on, as well as when switching the power supply off,
the burner goes through a stop procedure.

6.4. STARTING THE PELLET BURNER

When missing stop signal or in case of emergency situation and there is difference between
the adjusted and the measured temperature from the To sensor, then the burner starting
procedure initiates. The initial fuel doze is loaded and the ignition switches on.

After establishing the presence of flame the burner heating output increases. When the
modulation zone „Zone_reg” has been reached the burner heating output decreases and
when the desired water temperature or flue gases temperature has been reached the burner
operates at its minimum heating ouput. When higher than the adjusted temperature has been
reached, the system responds with stop procedure.

When the burner is in the modulation mode and the power is reduced accordingly, upon
temperature decrease the power starts to increase automatically.

Before igniting other suitable fuel in the form of firewood and wood chips in Bisolid Automat
series hot water boilers check:

 Water quantity in the heating system.
 Sealing of the heat-exchanger cover.
 Installed pellet tube burner condition.

The flue gases flap should not be left opened except for 1-2 minutes while

loading the boiler fuel hopper with other suitable fuel (firewood and wood chips).

The role of the flue gases flap is to bring the flue gases out of the boiler fuel hopper to the
chimney only during loading other suitable fuel. The flue gases flap is opened before opening
the door for loading the boiler other suitable fuel to enable extraction through the chimney of
the flue gases collected in the combustion chamber. This prevents smoke in the boiler room
and the risk of inhaling flue gases while loading other suitable fuel in the boiler. The flue gases
flap should no be opened for more than one or two minutes i.e. only during loading the hopper
with other suitable fuel, and should be closed immediately after that.

Do not start the boiler, before connecting the boiler to the chimney.
Check chimney connections before starting the boiler.
Check chimney draft. If the draft exceeds the recommended values install a

draft regulator.

In the transition seasons it is recommended boiler operation ONLY with wood
pellets, in order to avoid the danger of overheating when is used fuel in the
type of firewood or wood chips.

Other suitable fuel ignition (firewood and wood chips) is done as follows:

Bisolid Automat OM-BAV05/02/2018/EN 54

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

%

The pellet tube burner may operate both independently and by using other suitable fuel. When
starting the pellet burner, in case no other suitable fuel is added, the burner will operate as a
standard pellet burner. When starting the burner in the event that other suitable fuel is added,
other suitable fuel ignition takes place, then the burner stops and the combustion process
continues with other suitable fuel (firewood and wood chips). The other suitable fuel
combustion process will continue until other suitable fuel is available in the boiler fuel hopper.
In the event that other suitable fuel is exhausted (firewood and wood chips), the pellet burner
will continue to operate maintaining the temperature set by burning wood pallets.
Other suitable fuel can be added during operation of the pellet burner as well.

The pellet burner SHOULD NOT BE SWITCH OFF to the complete
combustion of the other suitable fuel (firewood, wood chips) in the boiler
combustion chamber!
While not completely burnt the embers from wood or wood chips the pellet
burner SHOULD NOT BE SWITCH OFF OR DISCONECTED!

Criterion for successful ignition of the other suitable fuel is the temperature of the flue gases.
When reaching this temperature, the burner modulates its operation to minimum power until
reaching a set water temperature (parameter) and after that it stops. The boiler enters into
other suitable fuel combustion mode. This mode continues until reaching the water
temperature set. When reached, the fan stops its operation and before that it has been in a
modulation mode approaching the temperature set. When the water temperature drops, the
fan is switched on again. It is possible that the burner starts again in case the water
temperature drops down below a set value (parameter).

At first ignition, to control the optimum condition of the flame, quality combustion control is
recommended. It includes monitoring the condition of the smoke from the chimney. Lack of
excessive smoke from the chimney is a sign of quality combustion, but if there is such, this
means that there is a deficiency of secondary air in the combustion chamber.

Bisolid Automat series hot water boilers are not designed to burn coal.

7.3. BOILER SWITCH OFF

We do not recommend accelerating the combustion process of the boiler. The fuel should burn
completely by itself on the combustion grate.

After switching off the boiler, clean the boiler, take out all combustion residue, empty the
ashbox (ash tray), clean contact surfaces of the feeding door and the ash box, and then close
the feeding door of the boiler and the door of the ash box.

7.3.1. STOPPING THE BOILER FOR A LONG PERIOD OF TIME

When stopping the boiler for a long period of time (at the end of the heating season), the boiler
should be completely cleaned from all unburnt deposits (soot, ash and sludge). Otherwise, the
accumulation of moisture in the unburned gases leads to excessive boiler corrosion.

The boiler can be operated only by adult persons who are well acquainted with
this operation manual.
Turn the boiler off every time, if any (even temporary) danger of presence

of flammable or explosive vapors in the room, from which the combustion air is
supplied to the boiler (for example, from paint during painting, from spraying
and laying molten substances, from gas leakage etc).

Boiler ignition with explosive substances is strictly forbidden.

Boiler overheating is forbidden.

The boiler and the chimney should be thoroughly cleaned at the end of the
heating season. Grease all hinges, chimney damper mechanism and other

moving parts.

9. BOILER INSTALLATION INSTRUCTIONS

9.1. BOILER INSTALLATION - GENERAL INFORMATION

Bisolid Automat series hot water boilers should only be installed by a specialized company
authorized for such activity. Boiler installation should be performed in compliance with the
preliminary designed project and the acting legal provisions.

The existing network of authorized service providers, which comply with these conditions, is
able to take responsibility for all boiler installations, their commissioning and warranty repairs.

Boiler installation should correspond to the acting prescriptions as well as to the operation and
installation manual. The manufacturer is not liable for damages caused as a result of
unqualified installation.

All problems (malfunctions) caused by boiler clogging with dirt from the

heating system and/or malfunctions caused by clogging are not covered by

boiler warranty card.

9.2. CHOOSING APPROPRIATE BOILER MODEL

The choice of an appropriate boiler model, i.e. its heating output is a main condition for the
economic and optimum operation of the equipment. The boiler should be chosen so that its
rated power corresponds to the heat losses of the site.

Choosing a boiler with too high heating output (oversize) leads to increased depositing of tar
and condensation. Therefore, it is not recommended to use boiler with higher power than the
heat losses of the site.

9.3. POSITIONING IN THE BOILER ROOM

Bisolid Automat series hot water boilers may be positioned in rooms that comply withl ocal
norms in effect. The boiler room should allow constant fresh air inflow, needed for the
combustion process. The air should be clean, free of halogenated hydrocarbons, corrosive
vapors and should not be too humid and dusty. The room should be protected against freezing
and air relative humidity should not exceed 80%.

When installing the boiler, for easy manipulation, it is necessary to pay attention to the
following (Figure 22):

 The minimum distance in front of the boiler should be 1000 mm to allow servicing the

pellet tube burner and to remove and put back the ashtray.

 The minimum allowed distance between the rear part of the boiler (where the boiler

connects to the chimney) and a wall should not be less than 500 mm.

 The minimum distance between the left and right side of the equipment and a wall

should be 400 mm to ensure free access to service the equipment.

 The minimum distance of the free space above the boiler should be at least 1200 mm

to ensure easy access to the fuel hopper when loading the fuel and to allow for
cleaning the accumulated ash on the heat exchanger.

 The minimum allowed distance between the outer parts of the boiler and the flue pipe

to flammable materials should be 200 mm.

 A safe distance of 300 mm should be observed in cases the degree of flammability of

the material is unknown. The safety distance should be respected when deploying
household objects, flammable materials and fuels in the boiler room.

Bisolid Automat OM-BAV05/02/2018/EN 60

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Figure 22. Positioning in the boiler room

The boiler should be steadily fixed over inflammable or heat-insulated foundation, which
should exceed the boiler contour with minimum of 300 mm in front and 100 mm in all other
sides. For easy service it is recommended that the boiler is positioned on an inflammable
foundation 100 - 150 mm high.

The boiler room should ensure constant combustion air flow. Air consumption depends on the
power of the boiler, respectively 45 – 60 m3/h (the corresponding air opening to allow air flow
is 200-300 cm2).

When the boiler operates do not touch any hot water connections or the

flue pipe.

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, or to
store the fuel in a premise different from the boiler room.

Do not put flammable materials on the top of the boiler or near it within the
safety distance.

9.4. WATER SUPPLY REQUIREMENTS

Bisolid Automat boiler is designed for systems with independent or forced water circulation. To
limit flue gas condensation and to increase the lifetime of the boiler at the same time, it is
recommended to use devices that do not allow lowering the temperature below 65 °C (flue gas
condensation point). For this purpose, for example, a three-way or eventually a four-way
mixing valve can be used, or a thermostatic valve.

Clean water should be used as a heat carrier, corresponding to the requirements of the
standards. The hardness of the boiler water should not exceed the values of the
recommended parameters (Table 18).

9.5. CONNETING THE BOILER TO THE HEATING SYSTEM

9.5.1. BOILER EXCESS HEAT RELEASE

The cooling loop is designed to release excess heat from the boiler to avoid exceeding the
maximum allowed boiler water temperature of 95 °C. Connecting the cooling loop to the boiler
flanges is shown in Figure 23 and to the two-way safety valve in Figure 25. In the event of
boiler overheat (the output water temperature exceeds 95°C), the thermostatic valve switches
on and the excess heat is being released by the cooling loop.

The two-way safety valve DBV 1 is used to release the excess heat in order to avoid
exceeding the maximum permissible temperature of the water in the boiler i.e above 95 °C. In
the event the system is equipped with a protective device against overheating, but
nevertheless the boiler overheats (the output water temperature is higher than 950С), the
protective device creates a cold water cycle, which remains active until the temperature
decreases below the limit value. At this point, the discharge cooling device and the cold water
running through the system close simultaneously.

9.5.2. PURPOSE OF THE TWO-WAY SAFETY VALVE

It is imperative to install the two-way safety valve. The installation of the

two-way safety valve is performed by a qualified and competent specialist!

Bisolid Automat OM-BAV05/02/2018/EN 62

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

The two-way safety valve DBV 1 is used for protecting boilers against overheats. Outlet and
inlet valves are integrated in the valve body operated by a thermostatic element. Upon
reaching the limit temperature, the outlet and inlet valves open simultaneously allowing for
cold water to start flowing into the boiler and hot water to start discharging out of the boiler.
Upon lowering the temperature to a level below the limit value, the outlet and inlet valves close
simultaneously.

Figure 23. Two-way safety valve DBV 1

A - Cold water inlet.
B - Outlet to the boiler.

In the event of activation of the two-way safety valve that might cause inflow

of water, not meeting the requirements set out in Table 18, the water in

the system should be treated as per the requirements. Furthermore,

the pressure in the heating system should be adjusted to the desired value.

C - Draining outlet - pipeline.
D - Inlet from the boiler.

The two-way safety valve does not replace the safety valve.

If the pressure in the water pipeline is higher than 6 bar, a reducing valve should be installed
on the cooling water inlet. It should also be installed when after an additional cooling the
pressure in the heating system is too high. In these cases, it is recommended that the
pressure of the reducing valve is adjusted at a value twice the value of the pressure necessary
for the heating system, and the minimum is 2 bar.

9.5.3. INSTALLATION OF THE TWO-WAY SAFETY VALVE

The installation of the two-way safety valve should be performed only by

a qualified person. For optimum operation of the thermostatic two-way safety
valve, it is necessary to comply with the prescribed conditions for installation

and to observe the flows direction indications marked on the valve body.

Bisolid Automat OM-BAV05/02/2018/EN 63

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

The safety valve is always mounted directly on the boiler (in the upper left part of the boiler) or
to the outlet pipe. When installing the valve, it should be checked whether the use of a 3/4" tip,
which can be either in the pipeline or on the boiler, provides complete immersion of the valve
thermostatic element after installation of the valve.

After mounting the tip in position "C" (Figure 23), the draining pipeline, through which the
waste water along with the hot water outflow, is connected,

The cooling water supply is connected in position "A" (Figure 23) according to Figure 25,
which supplies the boiler with cooling water after commissioning the valve. Particulate filters
should be installed in the place from where the cooling water is supplied.

The pipeline, which according to Figure 25 joins the return pipeline of the heating system near
the boiler is connected in position "B" (Figure 25),

The valve should be installed to the boiler according to Figure 25 i.e. outlet "C" - the draining
pipeline outlet should be positioned downwards.

It is necessary to install a safety valve for maximum overpressure of 4 bar

on the system and its dimensions should comply to the rated power of the
boiler. The safety valve should be positioned directly behind the boiler. There
should not be any shut-off valve located between the safety valve and the

boiler. If you have any questions, please, contact an authorized installation and

service center.

9.5.4. TWO-WAY SAFETY VALVE PERIODIC MAINTENACE

A control checkup should be performed once a year by appropriate turning of the head of the
two-way safety valve to remove any impurities precipitated on the valve. It is also necessary to
clean the filter on the cooling water outlet.

9.6. BOILER CONNECTION TO THE SMOKE EXTRACTOR

The smoke extractor is fixed to the chimney neck by 5 mm diameter rivets. The shortest
possible way should be chosen to connect the flue pipe from the boiler to the chimney at an
angle and upwards.

The smoke extractor should be brought to the chimney and should be fixed to the chimney
neck not to allow any accidental or arbitrary movement. The smoke extractor should not be
longer than 1.5 m and if conditions allow, additional elbows should not be used. All smoke

Bisolid Automat OM-BAV05/02/2018/EN 65

INSTALLATION, OPERATION AND MAINTENANCE MANUAL

extractor components should be made of non-combustible materials. Flue pipes for solid fuels
are very well adjusted pipes, which are installed in the same direction as the flue gases.

9.7. BOILER CONNECTION TO THE CHIMNEY

Bisolid Automat series boilers in central heating systems should be connected mandatory to a
separate chimney with appropriate chimney draft, which is a main precondition for optimum
operation of the boiler.

The chimney draft affects boiler thermal power, its performance and lifetime. The chimney
draft depends on chimney cross-section, height and roughness of the inner wall, and
furthermore on the difference between the flue gas temperature and the outside temperature.
The most suitable chimneys are the insulated chimneys and those with a chimney insert. The
actual draft can be measured by an authorized installation and service company using a
special gas analyzer.

The smoke extractor between the boiler and chimney should be insulated with mineral glass
wool. The smoke extractor and chimney must be made of steel or equivalent material that can
be used at temperatures around 400 °C.

All system connections for the flue gases must be solid and reliable to perform better
combustion and achieve high efficiency. The smoke extractor need to be connected to the
chimney using the shortest way and in the amounts indicated in Figure 26. The horizontal links
and elements that increase the pressure loss such as elbows should be avoided. Should not
be used as a single vertical stack steel tube. The chimney must be made of an inner and an
outer surface. The outer surface can be made of steel or brick. On the inner surface of
chimneys is recommend to use elements of stainless steel to prevent corrosion. The space
between the inner and outer surfaces of the chimney should be insulated to prevent
condensation of the flue gases.

At the lowest level of the chimney, there must be a hole with lid for cleaning, which is
necessary to be made of steel.

These dimensions in Figure 26 are indicative only. The working

installation depends on the diameter, height, roughness of the wall of the

chimney, temperature difference between the combustion products and the

external air temperature. We recommend using of a chimney built-in metal

insert.

The dimensions of the smoke extractor and the chimney must not be smaller than the chimney
neck dimension from the boiler. The diagram in Figure 27 is recommended for dimensioning of
the total height and minimum inner diameter of the chimney, depending on the boiler heat
output if it is not explicitly stated in the mandatory local regulations.

If the chimney draft is insufficient or chimney is not built according to the project

(bad condition of the structure, without insulation, blocked etc.) can occur big

problems in combustion. In this case, we strictly recommend the chimeny

condition to be controlled by the technician who will identify and remedy any

irregularities.

9.8. TRANSPORTATION AND STORAGE

Upon dispatch, the manufacturer offers the boilers mounted on wooden pallets and fixed
against displacement with screws. The boilers should not be transported in position different
from their normal operating position.

It is necessary to provide at least normal storage conditions for boilers during their storage and
transportation.

Do not apply pressure on the boiler packaging and covers during storage and transportation.

Boilers should not be carried or transported without the use of forklift trucks,
trolleys or other wheeled vehicles for transportation.

Packaging is disposed of in one of the secondary raw materials centers or in the municipal
landfill.

The disposal of the product (the boiler) after expiration of its lifetime is done in one of the

In all other cases, the repair of any failure and damage should be performed by the
manufacturer or an authorized service provider.

An obligatory condition for the normal operation is the presence of pellets, as
main fuel. Loading wood chips, as other suitable fuel to be made in operating
burner at steady state (presence of stable flame). Loading of firewood can be
made as in already operated burner, and in the absence of equipment start.
The requirement for the second case is loading with wood to be realized in the
way to is not to close burner tubus, i.e. to provide normal flame output. There is
possibility to realized start delay of the equipment – the preliminary loaded
boiler with wood is automatically ignites by external start (for example GSM) or
with или by simply pressing of the switch START. This is significant advantage
if this facility – automatic ignition of the other suitable fuel (even wood with high
moisture, difficult to burn in, hard flammable at normal boiler). The other
suitable fuel loading is made in open flue gases flap to the chimney with
purpose to limit smoke forming at the cover opening for loading.
