TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
CAUTION! Hot surface!
Risk of burns if you touch the running system.
Burner housing, body and flange are hot surfaces
during burner operation.
- It is strictly prohibited to open boiler inspection
doors with the burner running.
- Close and buckle-lock the hopper hatch cover after
filling the boiler with fuel. The hopper hatch cover
is not allowed to remain open for longer periods of
time.
-
Also, exercise caution when touching the
observation port for monitoring the burning
process. It may be hot.
1.2.3. Minimum clearances for installation and flammability
of construction materials
The applicable minimum clearances in your country may
differ from the ones specified below. Please, consult your
installer.
The minimum distance from the burner, heating boiler or
exhaust gas pipe to objects or walls must be at least 200 mm.
Table 1. Flammability of construction materials
Class А
– non-
flammable
Stone, bricks, ceramic tiles, baked clay,
solutions, plaster free of organic additives.
Class B
– hardly

boiler and walls.
For general safety considerations, we recommend that the
boiler be placed on a foundation made of class A material,
see table 1.
2. PRODUCT DESCRIPTION
Diagram 2
The CombiBurn high-efficiency dual chamber boiler is
designated for central heating of premises through burning
of wood pellets using a high-efficiency burner n integrated
to its lower combustion chamber. As alternative (backup
fuel) for it can be used wood logs, wood briquettes and coal,
which are loaded to the upper boiler chamber.
CAUTION! Do not use both chambers for burning
fuel at the same time.
To prevent heat losses into the ambience, the boiler is
insulated on the outside by high-temperature rock wool.
Efficiency – rate up to 89%. Designed in conformity with EN
303-5, class 5.
Set includes Dual-chamber boiler DC-A, pellet burner CW,
fuel hopper, removable ash-and-soot container.
2.1. Design structure of Dual-chamber boiler CombiBurn DC
Boiler body is with two combustion chambers. The wood
pellet burner is installed in the lower chamber. A metal grate
divides the upper from the lower combustion chamber. On
this grate the backup fuel (firewood, wood briquettes or
coal) is loaded. The boiler body is made of boiler grade steel
of thickness 6 mm for the combustion chamber and 3 mm
for the water jacket.
• Ecological.
Wood pellets and firewood used in the
combustion process are renewable energy sources with
minimum emissions.
•
Automated
. The main control unit, integrated in the
burner, manages the entire heating process. Controller
functions:
1) Fully automated ignition and pellet feed;
2) Fan ensuring stable operation of burner;
3) Self-cleaning function (adjustable 1-4 times over 24 hours
at equal intervals), programmable start time;
4) Built-in discharge mechanism drives the ash and soot into
a removable container;
5) Controls the operation of the circulation pump of the
central heating;
6) Controls the operation of the pump of the domestic hot
water;
7) Option for control by room thermostat;
8) Timer;
9) Optional for manual mode when using the upper chamber
and burned wood and / or coal.
•
Efficient
. On their way to the chimney flue gases make a
three-pass run around three water-filled barriers inside
the combustion chamber. Thus flue gas is cooled down
until exit from boiler, having all its heat energy transferred
to the water inside the jacket. The water jacket embraces
the combustion chamber in full to utilize the emitted heat
most efficiently. To prevent heat losses into the ambience,
the boiler is insulated on the outside by high-temperature
rock wool. Efficiency – rate 89%.
2.2. Automatic ash removal system. Ash deposit container
The specially designed ash-and-soot disposal system allows
the ash and soot to subside at the lowest point of the boiler
body
(1)
and be disposed inside the ash and soot container
(2)
using a transport screw
(3)
and a stirring mechanism
(9)
.
Ash-and-soot container is removable. It is equipped with
a handle
(4)
and wheels
(5)
for convenient disposal. Once
you have emptied the container of ashes, please make sure
you close the container cover tightly
(6)
, buckle-lock it to the
container buckles
(7)
, then buckle-lock the container to the
boiler buckles
(8)
.

2.3. Design of wood pellets burner CW
The burner is made of high-quality stainless steel able to
withstand temperatures of up to
1150°С
. The burner CW is
installed on side-flange of heating boiler.
