5. OPERATION AND CONTROL OF PELLET BURNER FROM BISOLID
GP XX_B HC> SERIES
5.1. DESIGNATION OF THE PELLET BURNER CONTROLLER
The controller is designated to provide automatic control of the combustion process and
adjustment of the pellet burner’s heating output, depending on the building and premises
heating needs.
5.2. OPERATION OF THE PELLET BURNER CONTROLLER
The device can control the following system modules:
Fuel transport auger.
Fresh air and extraction fans.
Electrical heating element for ignition of the pellets.
Cleaner element for ash cleaning.
Circulations pump for the boiler.
At primary switch on, as well as when switching the power supply off, the burner
goes through stop procedure.
5.3. 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 (there is service
parameter for adjustment) and when the desired 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 therefore the power is reduced with a
decrease in temperature in the automatic way the power is increased.

determined the heating water tempearture.
5.6.4. DETERMINATION OF THE ASSIGNMENT FROM ROOM
THERMO REGULATOR
This method is applicable only if is operating with contact room thermostats with
"independent output" (See section "Service Settings").
Time for optimisation.
Using of time for optimisation allows to reducing fluctuations in the assignment of the hot
water, which leads to a better control of the hot water. It can choose from 0 to 60 min, in
increments of 5 minutes. (See section "User settings").
When there are switches on and off from the room regulator and it operates without
optimization (0), the heating water adjustment becomes:
At start - maximum.
At stop – minimum.
When there are switches on and off from the room regulator and it operates with optimisation
(5-60 min.), the heating water adjustment becomes:
At start – increase starts, as the maximum assigned temperature value is reached at
the end of the optimization time, only in case there is no stop occured during this
period.
At stop – decrease starts, as the minimum assigned temperature value is reached at
the end of the optimization time, only in case there is no start occurred during this
period.

1. The handle of the cleaning mechanism of the burner is pulled back until it stops moving
as shown in Figure 5.
2. The handle is moved forward until it stops moving as shown in Figure 6.
3. This action is repeated 2 to 3 times for the complete cleaning of the fire-grate, once per
a day.
The handle of the cleaner should be in extremely retracted position to the
burner to allow the pellet burner to operate normally.
The pellet burner series Bisolid GP xx_B hc> is cleaned in the following cases:
During the operation of the pellet burner:
- The pellet burner can be cleaned and at its operation. In this way of cleaning is
discarded small dose unburned fuel, but the advantage is that there is no need any
waiting time, i.e., cleaning can be done immediately on the customer request. The
burner is programmed to continue working after this type of cleaning.
Cleaning of the pellet burner without interrupting the operation of the device:
- When a device does not operate assigned to it by the program, for example daily or
weekly thermostat.
- When a device does not operate and is in standby mode due to the achieved
temperature.
When the pellet burner is switch off:
- When a device is switched off by the user, it is necessary waiting for the complete
combustion of residual fuel according to the parameters listed in Table 9.
The cleaning of the pellet burner, which is carried out from outside with the help
of the mechanism for cleaning, does not require protective equipment.
5.16. PELLET BURNER SERVICING
The regular pellet burner servicing by the user guarantees efficient, economic and reliable
operation of the appliance.
The user has to periodically, at least once per day or longer, depending on the fuel ash
content, but no longer than five days of operation, to switch off the burner. This measure
guarantees effective after-burning of the fuel and combustion chamber cooling.
After the pellet burner cools down the ash and/or slag must be cleaned from the combustion
chamber fire-grate. The flexible pipe connecting the fuel transport auger and the burner fuel
inlet pipe must be cleaned from dust at least once per week.
Dust depositing on the flexible pipe walls can lead to distortion of the fuel
feeding, ignting the dust as a result of emergency situation, in consequence of
which hot flue gasses might pass through it.

6. INSTALLATION INSTRUCTIONS FOR PELLET BURNER SERIES
BISOLID GP XX_B HC>
6.1. PELLET BURNER INSTALLATION – COMMON INFORMATION
The wood pellet burner series Bisolid GP xx_B hc> must be installed only by specialized
company, authorized for such activities. The pellet burner installation must be performed
depending on the solid fuel hot water boiler type from Bisolid series, the preliminary designed
project and acting legal provisions.
The existing networks of authorized service organizations comply with these conditions and
are able to take responsibility for all pellet burners Bisolid GP xx_B hc> (GP 20_B18 hc>, GP
25_B hc> и GP 32_B hc>) installations, their initialization in operation and warranty repairs.
Installation of the pellet burner must comply with the acting regulations and directives as well
as to the operation and installation manual. The manufacturer is not responsible for failures or
damages caused by unqualified installation.
The pellet burner series Bisolid GP xx_B hc> must be connected to the power
supply only by qualified authorized person.
All problems (failures) caused by incorrect installation of the pellet burner are
not covered by the pellet burner’s warranty cards.
6.2. CHOOSING A PELLET BURNER
The choice of suitable pellet burner series Bisolid GP xx_B hc> is necessary to be made
accordingly to the heating output of the different types and models hot water boilers Bisolid.
The correctly chosen pellet burner used for installation to the mentioned hot water solid fuel
boilers guarantees economic and optimum operation of the system boiler – burner.
The choice of pellet burner with too high nominal heating output, compared to the boiler’s
output, leads to increased consumption and fuel expences.
The choice of pellet burner with much lower nominal heating output, compared to the boiler’s
output, leads to impossibility for reaching the boiler’s nominal parameters and low efficiency
Page 30
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Bisolid GP xx_B hc> . OM-BSGPHCV02/07/2017/EN 30
6.3. POSITIONING OF THE PELLET BURNER
The pellet burner series Bisolid GP xx_B hc> can be installed on hot water boilers, which are
positioned in uninhabitable premises (for example boiler room, basement).
The pellet burner and 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, with ambient
temperature in the range from +5°C to +35°С and with no more than 80% relative humidity of
the air.
Safe 200 mm distance must be kept in the cases when the flammability level of the material is
unknown. The same safety distance must be kept also for domestic objects, flammable
materials and fuels situated in the room, where the burner is positioned.
Do not put flammable materials over burner’s main module top side or near it
within the safety distance.
The main module of the pellet burner series Bisolid GP xx_B hc> must be installed in
horizontal position towards a suitable solid fuel hot water boiler. The pellet burner position has
to be considered so it can provide its reliable operation, easy cleaning, handling and servicing.
Correct positioning during the pellet burner installation guarantees reliable and efficient
parallel operation of the burner and the hot water boiler.
The fuel transport auger must be installed near to the already installed pellet burner, in order
to secure its good connection, through the flexible pipe, with the burner’s main module fuel
supply pipe.
About the positioning of the fuel transport auger we recommend that the angle between the
horizont plane and the auger center axis is 45o. By this way an optimum operation of the auger
motor and the burning process will be guaranteed.
If the fuel transportation auger’s angle changes, then the wood pellet
consumption changes respectively depending on the pellet burner heating
ouput.
When the fuel transportation auger’s angle decreases, then the wood pellet consumption
increases and respectively the pellet burner heating output increases. When the fuel
transportation auger’s angle increases, then the wood pellet consumption decreases and
respectively the pellet burner heating output decreases.
The fuel transport auger and the wood pellets hopper, where it is located, positions are
recommended to be situated in a way that provides easy access to the pellet burner, for the
purposes of adjustment, cleaning and servicing.
