TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
8. FILLING THE HEATING INSTALLATION
Table 6
Problem Prevention
Possible installation
damage due to strains
in the material caused
by temperature
differences
Fill the heating installation only in
cold conditions (inlet temperature
must not exceed 40°C ).
Danger of installation
damage due to
accumulation of
deposits
Condensate formation
and tar deposits
may shorten boiler’s
operational life.
- Do not operate the heating boiler
for a long period of time in partial
load mode
- The temperature at the boiler
inlet must not be less than
65°C
,
boiler water temperature must be
between
80°C
and
85°C
.
- Use the boiler for a short period to
heat warm water in the summer.
9. OPERATION OF BOILER

Failure to observe the installation and operating
requirements described in the manual and the
service booklet voids the warranty.
9.1. Operation of Dual chamber CombiBurn DC-A
• IGNITION. After the start up of the boiler from the control
panel, the main pellet auger conveys certain amount of
fuel from the pellet hopper to the burner. This specific
amount of pellets is set by the installer and depends on
the fuel characteristics. The fed-in quantity of pellets is
conveyed from the auger conveyor built in the burner to
the combustion chamber where it is being ignited using
hot air.
• BURNING. The burning process takes place in the
combustion chamber and, after it has been fed into the
combustion chamber, the fuel is then transported from
the internal auger conveyor to the combustion chamber in
portions. This allows for constant and optimal burning rate
of the fuel. Flame intensity is monitored by a photosensor
which monitors the burning and feeds data into the
control unit which enables the starting or stopping of the
combustion process, if necessary. The output of the burner
is determined by the intervals preset on the control panel
taking into account the heating value, size and density of
the pellets.
•
AUTOMATIC CLEANING SYSTEM
. The Dual chamber boiler
DC-A is equipped with innovative automatic cleaning
system for combustion chambers of both divices.
A powerful cleaning motor built in the burner body, air is
being blown in at high speed and rate thus removing all
residues – ash, noncombustible inclusions, etc. built up
into the combustion chamber of the burner.
At the same time the boiler turns on automatic ash
removal which is transported to the ash container through
screw located in the lower part. These automatic cleaning
cycles last several seconds and can be additionally
adjusted as well as their repeat rate depending on the load
of the burner.
9.2. Important recommendations for long-lasting and
correct operation of the boiler
- For assembly and installation of the burner follow the
requirements in this manual.
- Use only recommended in this manual fuel.
- Clean ash-and-soot container weekly.
- Disassemble the burner from the boiler body before clean
it. Depending on fuel and burner settings, clean the pellet
burner once a week:
1) Disassemble pellet burner.
2) Use a wire brush to clean burner chamber
3) Use a vacuum cleaner to clean the ashes underneath the
chamber
4) Assemble the cleaned burner
- Do not use both chambers at the same time
- User`s training for operation and maintenance of burner is
performed by an authorized installer or service shop.
- It is mandatory to clean and complete maintenance once
per year of all burner components and boiler chamber
components.

10. CONTROLLER UNIT
10.1. Controller view. Explanation of buttons and indicators.
LCD screen: The controller screen displays the information
for the operation of the facility.
Explanation of buttons:
Button F
– function key (button).
Used to move from one page to the
next menu, and passing the burner
from one stage to another (Manual
-Auto – Programe).
Button ”Enter” – Used to move
from one line to another menu of the
controller. Confirm the entered value.
Buttons “Navigation arrow Up” and “Navigation arrow
Down” – Used to change the value of a parameter
in the menu. After entering the correct value press button
“Enter”, to move to next parameter.
Display symbols explanation:
Auto Clean symbol appears in right upper part of
display. Active auto cleaning symbol means boiler
automatic cleaning mode.
Crossed-out flame symbol appears in upper right part
of display. Means that the boiler enters into
Extinguish mode.
CH priority
/Radiator /symbol appears in upper part
of display. Means than Central Heating priority is set
to heat up the central heating.
Domestic Hot Water /shower/ priority symbol
appears in upper part of display. Means than DHW
priority
is set to heat up the domestic hot water.
When set DHW temperature is reached, DHW pump stops
and CH pump is activated.
Parallel pumps /shower and radiator/ symbol appears
in upper part of display. Means that is set equal
priority to both pumps. They work in parallel and are
controlled by temperature sensors.
