WE HOPE YOU WILL BE SATISFIED WITH OUR PROD-
UCT, AND WE RECOMMENED TO COMPLY WITH
THESE MAIN REGULATIONS NECESSARY FOR
LONG SERVICE LIFE AND CORRECT FUNCTION OF
THE BOILER
1. Assembly, firing-up test and operator‘s training must be carried out by an installation compa-
ny trained by the manufacturer; this company also fills in a boiler installation report (p.41).
2. During the gasification process, wood tar and condensates (acids) form in the fuel storage tank.
Therefore, there must be a Laddomat 22 or a thermoregulatory valve installed behind the boiler in
order to keep the minimal temperature of water returning to the boiler at 65 °C.
Operating temperature of water in the boiler must be in the 80 - 90 °C range.
3. Every circulating pump in the system must be regulated by an individual thermostat in order to
keep the specified minimum temperature of water returning to the boiler.
4. The boiler must not be permanently operated in an output lower than 50 %.
5. The boiler operates environmentally-friendly at the nominal output level.
6. When operating the boiler in a lower output mode (summer operation or heating up warm ser-
vice water), it is necessary to fire-up daily.
7. Wethereforerecommend installingthe boilerwith accumulatingstorage tanksand Laddomat 22,
which provides 20 - 30 % fuel consumption decrease, and longer service life of both – the
boiler and the chimney and user-friendlier operation.
8. If you cannot install the boiler into an accumulation system, then we recommend installing it at
least with one equalising tank; the volume of which should be 25 l per 1 kW of the boiler output.
9. Use only dry fuel with 12 - 20 % moisture content – higher moisture content decreases the
boiler’s performance and increases consumption.
Boilers with an extraction ventilator are marked with S (DC 70S excluded) at the end of the
label.
CAUTION – if the boiler is installed with a Laddomat 22 or with a TV 60/65/70/75 °C
and with the accumulation tanks (see attached schematics), the guarantee period for
the boiler drum is extended from 24 to 36 months. The guarantee period for other
parts remains unaffected. In non-compliance with these instructions the drum’s and
the heatproof pipes’ service life may dramatically decrease. The boiler drum may cor-
rode in as little time as 2 years.
CAUTION - INSTALLER SHOULD ALWAYS COMPLY WITH LOCAL PLANNING
AND BUILDING REQUIREMENTS.

1. Intended use
The environmentally friendly boilers ATMOS DC 15/18/20/22/25/30/32/40/50/70/75 are designed
for heating family houses, cottages, holiday houses and other similar buildings. Boilers are suitable
for buildings with heat loss ranging between 15 - 75 kW, depending on type. The boilers are construct-
ed mainly for burning logs. Any type of dry wood is suitable for heating, especially wooden logs up
to a maximum length 330, 530, 730 and 1000 mm as per the boiler type. If you use logs of a larger
diameter the nominal output is then decreased and the burning period prolonged. The boiler is not
intended for burning saw dust or small-particle wood waste. These can be burnt in small quantities
only, together with log-firewood. MAX.10 %. Due to their huge feeding hoppers, the boilers save the
user a lot of laborious wood wood preparation and splitting operations. They save both - the physical
effort and also the time dedicated to these operations.
2. Technical specifications
The boilers are designed for burning wood based on generator gasification principle utilising an
extraction ventilator (DC15E excluded), which extracts the waste gas from the boiler or blows the air
in the boiler.
a) Gas extraction ventilator – for boilers DC18S, DC22S, DC25S, DC30SE, DC32S,
DC50S, DC40SE, DC50SE, DC75SE, DC20GS,
DC25GS, DC32GS, DC40GS, DC22SX, DC30SX,
DC40SX
b) Pressure ventilator – for DC70S (DC80)
c) Without ventilator – DC15E
The boiler drum is manufactured as a welded structure from 3 - 8 mm thick steel sheets. The top
comprises the Fuel Hopper and the lower end of this hopper comprises a heatproof shaped piece with
longitudinal opening for combustion remnants and gases. The burn-off chamber is equipped with
ceramic shaped pieces. There is a vertical waste gas duct at the rear of the boiler body which is in its
upper section equipped with an ignition valve. The upper part of the waste gas duct is equipped with
gas outlet pipe for connecting to chimney. The front wall is in the upper part equipped with stoking
door and with ashtray door in the lower part. In the front section of the upper hood there is an ignition
valve pull rod. The boilers’ drum is externally heat insulated with mineral wool placed beneath the
sheet metal covers of the boilers’ external housing. A control panel for electromechanical regulation
is situated in the upper part of the boiler. In the rear section of the boilers, there is a primary and sec-
ondary air feeding duct fitted with a control valve, which is operated by FR 124 draught regulator.
Primary and secondary air is preheated to high temperature. For boilers DC50SE, the valve with the
FR 124 draught regulator is replaced with servo drive with inbuilt spring. This boiler also contains
two special steel plates alongside the gasifying nozzle.

Description:
1. Thermometer – monitors the temperature of water exiting the boiler.
2. Main switch – allows for completely shutting down boiler if necessary.
3. Waste gas thermostat – is used to switch off the ventilator when the fuel has burnt out.
CAUTION – when firing up (igniting), set the waste gas thermostat to (“0 °C“- firing-up).
After flaring up, set the waste gas thermostat to „operation“. It is necessary to detect the
optimal operating position. Should the waste gas temperature fall below the preset value, the
thermostat switches the extraction ventilator off. If you want the ventilator to re-start, set a
lower temperature on the waste gas thermostat (set to “0 °C“ - firing-up).
4. Control thermostat (boiler) – controls the boiler operation depending on the temperature of
water exiting the boiler.
5. Safety irreversible thermostat – serves as boiler protection against overheating in case of con-
trol thermostat failure or as an indication of exceeding the emergency temperature. If such ex-
ceeding occurs, it is then necessary to depress the thermostat.
6. Ignition valve pulling rod – serves for opening the ignition valve during heating or inserting
fuel.
7. Area for electronic regulation of the heating system can be used to house any type of regulation
system that fits into an aperture of (92x138 mm). The electric harness is prefabricated and ready
to be used for the regulation’s power supply.
8. Pump thermostat in the DC15E boiler for switching the pump in the boiler circle (75 - 80 °C)
Advantages of boilers
Boilers provide burning at high temperatures with the generator gasification function. That re-
sults in fuel saving and ecological operation. The boilers pre-heat the primary and secondary air to a
high temperature which results in warm and stable flame of stable burning quality. Boilers marked
with GS provide this process in the ceramic combustion area with primary air side inlets. Boilers
equipped with extraction ventilator require simple and easy operation, and are marked with “S”
(DC70S, DC15E excluded). Large fuel hopper allows burning of the log pieces with the maximum
length 330 - 1.000 mm, depending on the boiler type. Large pieces of waste wood can also be burned.
All boilers are equipped with cooling loop for overheating protection.

6. Fuel
Specified fuel is dry chopped log fire wood, Ø 8O - 150 mm, at least two years old, moisture 12 %
to 20 %, caloric power 15 – 17 MJ.kg-1 and log length 330 - 1000 mm as per boiler type. Fuel dimen-
sions are stated in section 3 „Technical Data“. It is also possible to burn large pieces of wood waste in
combination (max. 10 %) with crude logs.
Basic wood burning data
You can ensure maximum output and a long service life if you burn wood which has been left for
at least 2 years to dry. The following graph illustrates the relationship of moisture content to heating
capacity of the fuel. The energy content declines dramatically with increased water contents.
Example:
Wood with 20 % moisture contents has thermal power of 4 kWh /1 kg of wood
Wood with 60 % moisture contents has thermal power of 1.5 kWh /1 kg of wood
• Example – spruce wood which has been stored for 1 year under shelter – see graph

Raw wood does not burn easily, produces a lot of smoke and substantially decreases
the service life of your boiler and chimney. Boiler output drops as low as 50 % and fuel
consumption doubles.

8. Environment type and boiler placement in a boiler room
Boilers may be used in a “basic environment” - AA5/
AB5 as specified in Czech standard ČSN3320001.
Boilers must be placed in a boiler room with sufficient
air access necessary for combustion. Placing boilers
in living areas (including halls) is not permitted. The
combustion air inlet aperture in the boiler room must
be of minimum 300 cm2for boilers of 15 - 75 kW
outputs.
1 - Chimney
2 - Flue duct
3 - Boiler
9. Chimney
Connecting the appliance to the chimney vent stack must always be carried out with the per-
mission of the appropriate chimney authority. The vent stack must always be capable of providing
sufficient draught and it must discharge the waste gas into the open atmosphere in a reliable manner
for all possible operating conditions. The dimensions of the individual vent stack must be correct to
ensure good functionality of the boiler; because the draught influences combustion, performance
and the service life of the boiler. The chimney draught is directly dependent on its cross section,
height and the inner wall ruggedness. It is not permitted to connect another appliance into a chimney
into which a boiler is connected. The chimney diameter must not be smaller than the boiler outlet
We recommend providing a concrete (metal)
base under the boiler.

GB
(min. 150 mm). The chimney draught must comply with the specified values (see technical data, page
8). The chimney must not be excessively high, otherwise the boiler effectiveness is decreased and the
combustion is affected (the flame “breaks”). In case of excessive draught, install a throttle valve in the
flue gas duct between the boiler and the chimney.
Indicative values of the chimney cross section dimensions:
20 x 20 cm height 7 m
Ø 20 cm height 8 m
15 x 15 cm height 11 m
Ø 16 cm height 12 m
Exact chimney dimensions are stipulated in Czech standard ČSN 73 4201. Specified chim-
ney draught is stated in section 3 „Technical Data“.
10. Flue-gas duct
The flue-gas duct must be connected into the chimney
vent stack. If the boiler cannot be connected to the chimney
directly, the appropriate flue-gas duct extension must be as
short as possible in the given circumstances, but not longer
than 1m, it must be without additional heating surface and
must incline upwards in the direction towards the chimney.
Flue-gas ducts must be mechanically durable and sealed
against combustion products and gas penetration, and it must
be possible to clean them inside. The flue-gas ducts must
not be lead through another person‘s apartment or property.
The internal diameter of the flue-gas duct must not be larger
than the internal diameter of the chimney intake and it must
not decrease in width in the direction towards the chimney.
Use of elbow-pipes is not suitable. Methods for providing
flue-gas duct entries through flammable material structures
are stipulated in appendices 2 and 3 of the Czech standard
ČSN 061008. These are appropriate for mobile installations,
wooden cottages etc.
1- Waste gas thermometer
2- Cleaning aperture
3 - Throttle valve (draught limiter)
INFO - In case of excessive chimney draught, install a throttle valve or draught limiter
(regulator) /3/.

11. Fire prevention during installation and use of heating ap-
pliances
Selected from ČSN 061008 – Fire safety of local appliances and heat sources.
Safe distances
When installing the appliance, keep a minimum safe distance of 200 mm from building materials.
This distance is valid for boilers and flue-gas ducts positioned near flammable materials of the B, C1
and C2 flammability class materials (the flammability classes are listed in chart 1). It is necessary to
double the 200 mm safe distance if the boilers and flue-gas ducts are placed near flammable materials
of C3 class (see chart 1). It is also necessary to double the safe distance if the flammability class of
the material in question cannot be determined. The safe distance can be decreased to one half (to 100
mm) if a heat insulating, non-combustible screen (asbestos board) of a 5 mm minimum thickness, is
placed 25 mm from the protected combustible material (so called flammable insulation). The screen-
ing board or protection screen (on the protected object) must exceed the boiler outline including its
flue-gas duct on each side by at least 150 mm and by at least 300 mm above its upper surface. The
screening board or protection screen must be also used for all fixtures and fittings from combustible
materials in cases where the safe distance cannot be maintained (such as in mobile structures or
wooden cottages etc. - for more details see ČSN 061008 standard). The safe distance must be main-
tained even when placing fixtures and fittings near the boilers.
If boilers are placed on floors from combustible materials, the floor must be fitted with a non-com-
bustible, heat insulating pad exceeding the boiler’s ground-outline on the side where the stoking and
ash-pan apertures are, by at least 300 mm (in front of the aperture) and on all the other sides by at least
100 mm. The non-combustible, heat insulating pad can be made from any material of A flammability
class.
Chart 1
Flammability classes of building mate-
rials and products
A – non-combustible granite, sandstone, concrete, bricks, ceramic tiles, mortars,
reproong plasters etc.)
B – non-easily ammable Akumin, Izomin, Heraklit, Lignos, basalt felt boards, bre-
glass boards, Novodur
C1 – low degree of ammability deciduous tree wood (oak, beech), Hobrex boards, plywood,
Sirkolit, Werzalit, hardened paper (Formica), Ecrona)
C2 – medium degree of ammability coniferous tree wood (pine tree, larch, spruce), chipboards
and cork boards, rubber ooring (Industrial, Super)
C3 – high degree of ammability breboards (Hobra, Sololak, Sololit), cellulose materials,
polyurethane, polystyrene, polyethylene, foamed PVC
In circumstances when there is a risk of temporary access of flammable gases or fumes, or
during works when a temporary fire or explosion risk may possibly occur (such as gluing
linoleum, PVC etc.) the boilers must be put out of operation long enough before the risk
occurrence. No items from flammable materials may be placed on the boilers or near
them for a distance lower than the specified safe distance (more see ČSN EN 13501-1).

12. Connecting boilers to the electrical power network
The boilers are connected to 230 V, 50 Hz mains with a mains cable without a plug. The mains
supply cable in case of repair it must be replaced with the same type by the servicing organization.
Connection, maintenance and reparation can be made only by a qualified person in accordance with
valid regulations of the particular country.
CAUTION - The mains cable must not be equipped with a plug (designed to be connected
to a socket). It must be connected in a fixed way to a switchboard or junction box to avoid
confusion of the conductors.
Mains cable must be regularly checked and maintained in the prescribed condition. It is forbidden
to interfere in to the safety circuits and elements for safe and reliable operation of the boiler. If any
damage of electrical equipment must be the boiler out of operation, disconnect from the mains and
ensure a qualified repair according to applicable standards and regulations.
Connectors in side hoods of the boiler:
1- connector for income cabel (L - brown, N - blue, PE - green/yellow)
2- connector for extraction fan
