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 compa­ny 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 ser­vice water), it is necessary to fire-up daily.

7. We therefore recommend installing the boiler with accumulating storage tanks and 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 cor­rode 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 construct­ed 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 sec­ondary 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 con­trol thermostat failure or as an indication of exceeding the emergency temperature. If such ex­ceeding 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 re­sults 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 dimen­sions 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

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 cm2 for 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 per­mission 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.

Instruction manual - GB

www.atmos.cz

16-GB

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 chim­ney 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 screen­ing 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 main­tained 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-com­bustible, 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 mate­rials 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

17. Choice and connection method of control and heating ele-

ments

Boilers are provided to the user with the basic boiler performance control elements compliant with
requirements for convenient heating and its safety. The regulation ensures that the required temperature
of the water exiting the boiler (80 - 90 °C) is adhered to. The control of mixing valves and pumps is
not solved. With the exception of DC75SE, which is equipped with two thermostats 70 °C (pump con

­nection temperature during normal operation), 95 °C (pump connection temperature during emergency
state) for switching the pump in the boiler circle and with the exception of DC15E, which is equipped
with thermostat place in the panel and an outlet for the pump in the boiler circle. Connection of these
elements is illustrated in the wiring diagram. Each pump in the system must always be controlled by an
individual thermostat to avoid a temperature drop of water returning to the boiler under 65 °C. When
connecting the boiler without an accumulation tank or equalizing tank, the pump placed in the heated
building circuit must be switched on and off by an individual thermostat or electronic regulation so
that it only operates when the pump in boiler circuit operates. If two thermostats are used – each for
switching one pump – set the thermostat that switches the heated building circuit pump, to 80 °C, and
the thermostat that switches the boiler circuit pump, to 75 °C. Both pumps may only be switched by
one thermostat. We recommend to switch the pump in the boiler circle by the means of waste gas ther

­mostat built in the boiler (during fire-up), if the boiler is connected with the accumulation tanks and
Laddomat 22 and the if the gravity water circulation which prolongs the required temperature build
up functions well in the boiler circle. When switching the pump in the boiler circle by using the waste
gas thermostat built in the boiler panel, we recommend to install safety thermostat on the 95 °C pump
(see electric wiring diagrams). Thermostat in the boiler can be alternatively replaced with an attaching
thermostat on the boiler outlet which connects the pump in the boiler circle when the temperature rises
to 95 °C (parallel connection with the waste gas thermostat).
Setting the required water temperature for the building is always achieved by means of a three-way
mixing valve. The mixing valve can be regulated manually or by electronic regulation, which contrib

­utes to a more convenient and economical operation of the heating system. The connection of all the
elements is designed to suit specific conditions of the heating system. Electric installations related to the
additional equipping the boilers with the above mentioned elements must be carried out by an expert in

compliance with valid ČSN EN standards.

When installing the boiler, we recommend using a closed expansion tank. However, an
open tank may also be used if permitted in the standards of the specific country. The
boiler must always be installed in a way which prevents overheating (and subsequent
damage) even during a power cut. It is because the boiler has certain momentum.

There are several ways of protecting the boiler from overheating. Connecting an over­heat prevention cooling loop with a TS 131 3/4 ZA (95 °C) or WATTS STS 20 (97 °C)
valve to the public water system. In cases of personal wells, the boiler can be addi­tionally protected by using a back-up power supply (battery with an exchanger) for
operation back up of at least one pump. Another option is connecting the boiler to an
after-cooling tank and reversal zone valve.

When installing the boiler, position the rear section 10 mm higher in order to facilitate
circulating and air-bleeding.

For the heating system regulation we recommend regulation elements provided by the following
companies:

a) ATMOS ACD 01 - Eqvithermal controller set for solid fuel boilers
b) KOMEXTHERM, Praha tel.: [phone]
c) KTR, Uherský Brod tel.: [phone]
d) Landis & Staefa tel.: [phone]

18. Boiler corrosion protection

The specified solution is connecting the boiler with Laddomat 22 or with a thermoregulatory
valve, which can separate the boiler circuit from the heating circuit (primary and secondary circuits),
and provide minimum of 65 °C for water returning to boiler. The higher the temperature of water
returning to the boiler, the fewer tars and acids condensing; which damage the boiler. Temperature of
the outgoing water must permanently range between 80 - 90 °C. The combustion products (waste
gas) temperature must not drop below 110 °C during normal operation. Low waste gas temperature
causes condensation of tars and acids even when the specified outgoing water temperature of (80 ­90 °C) and returning water temperature of (65 °C) are adhered to. These conditions may occur when
using the boiler to heat domestic hot water (DHW) in summer, or when heating only a section of the
building. In this case we recommend connecting the boiler with accumulation tanks, or daily fir­ing-up. For outputs of 15 - 100 kW it is also possible to keep the minimum temperature of the return­ing water (65 - 75 °C) by utilising a three-way mixing valve with an electric actuator and electronic
regulation.

23. Laddomat 22

With its construction, Laddomat 22 replaces the
traditional connection composed of individual
parts. It is composed of a cast-iron body, ther­moregulatory valve, pump, non-return f lap valve,
ball valves and thermometers. When the water
temperature reaches 78 °C, the thermoregulato­ry valve opens the water supply from the storage
tank. The connection with Laddomat 22 is consid­erably easier and therefore, we recommend it. A
spare thermo-cartridge of 72 °C is supplied with
the Laddomat 22 device. It is used for boilers over
32 kW.

WARNING - For boilers with an output from 15 up to 100 kW we recommend using Lad-

24. Thermoregulatory valve

Thermoregulatory valve type, TV 60 °C
(65/70/75 °C) is used with solid fuel boilers. When
the boiler water temperature reaches + 60 °C , the
thermoregulatory valve opens and fluid from the
building heating circuit (2) enters the boiler circuit

( 3 →1). Inlets 1 and 3 always remain open. This

ensures that the minimum temperature of the wa­ter returning to the boiler is maintained. If need
be, a thermoregulatory valve set to a higher tem­perature (E.g. 72 °C) may be used.

Recommended sizes of the thermoregulatory valve TV 60 °C (65/70/75 °C).

25. Operating a system with accumulation tanks

Ignite the boiler and allow the accumulation tanks to “charge” to the required water temperature
of 90 - 100 °C by the boiler’s maximum output operation (2 to 4 loads). Then leave the boiler to stop
burning. Then keep withdrawing heat from the storage utilising three-way valve for a period of time
corresponding to the size of accumulation tanks and the external temperature. In the heating season
(and if adhering to specified min. accumulation tanks volumes – see chart) this could take 1 - 3 days.
If the accumulation method cannot be used, then we recommend using at least one tank of 500 - 1000
l volume for equalising the boiler start-ups and run-outs.

Tank insulation

A suitable solution is joint mineral wool insulation of the particular number of tanks (of required
volume) placed together into a plasterboard structure, or additional filling with granular insulation.
When using the mineral wool, the specified minimum insulation thickness is 120 mm. Another option
is purchasing tanks in a leather-cloth housing insulated by mineral wool (see the price list).

Advantages

The installation with accumulation tanks provides several advantages:

- lower fuel consumption (by 20 – 30 %), the boiler operates in full output and at an optimal effec­tiveness of 81 - 89 % until the complete combustion of the fuel

- prolonged boiler and chimney service life – minimum formation of wood-tars and acids

- possibility to combine it with other heating methods – accumulated electric power, solar collec­tors

- combination of wall radiators and floor heating

- convenient heating and ideal fuel combustion

- environmentally friendlier heating

26. Connection of overheat protecting cooling loop with a safe-

ty valve Honeywell TS 131 - 3/4 ZA or WATTS STS20

(valve opening temperature 95 - 97 °C)

ATTENTION – cooling loop to prevent overheating must be used in compliance with EN
ČSN 303-5 only for overheating prevention (never for heating up warm service water).

The TS 131 - 3/4 ZA or WATTS STS 20 valves, the sensor of which is placed in the rear of the
boiler, prevent overheating in the following way: if the boiler water temperature rises above 95 °C,
the valve opens and allows water from public water supply system to enter the cooling loop. This
water then absorbs the excessive energy and exits to the sewer. In case that a non-return flap valve has
been installed to the cooling loop water inlet for the purpose of preventing reversed water flow (which
might be caused by pressure drop in the public water supply system), the cooling loop must be fitted
with a 6 – 10 bar safety valve or with an expansion vessel of minimum 4 l volume. The boiler must
be protected against overheating at all times. If not, its damage or burst may occur.

27. Operating instructions

Preparing boilers for operation

Before putting boilers into operation, it is necessary to ensure that the system has been filled with
water, and air-bled. Wood boilers must be operated in compliance with the instructions stipulated in this
manual so that satisfactory and safe functioning is achieved. They can only be operated by adults.

Ignition and operation

Before fuel ignition, open the ignition valve /13/ by pulling the ignition valve pulling rod /17/ and
reduce the waste gas thermostat (DC15E excluded) for the ignition (to minimum - 0 °C). Through
the top door /2/ insert dry wood kindling on the heatproof shaped piece /5/. Place the kindling per­pendicularly to the channel recess in the shaped piece so that a 2 – 4 cm gap between the recess and
fuel is created; which allows the waste gas passage. Place paper or wood wool on top of the kindling,

then another layer of kindling and larger amount of dry wood. After ignition close the top door and
open the lower door. For faster flaring up the extraction fan may be switched on (DC7OS, DC15E).
When the fuel has caught sufficient fire, close the lower door, fill the storage tank completely with
fuel and close the ignition valve with its pulling rod /17/. Set the waste gas thermostat into the oper­ating position which it is necessary to determine for ideal operation. On the FR 124 draught (output)
regulator /22/ set the required outgoing water temperature 80 - 90 °C (note – DC50SE is not equipped
with draught regulator FR 124). If the boiler should work as a gasification appliance, then a layer of
glowing charcoal must be kept (known as reduction zone) above the gasifying nozzle. This can be
achieved by burning dry firewood of suitable size. When burning moist wood, the burner does not
operate as a gasification appliance, the fuel consumption increases dramatically, the boiler does not
reach the required output and the service life of both - the boiler and the chimney - decreases. If the
specified chimney draught is adhered to, the boiler operates up to 70% output without the ventilator.

Waste gas thermnostat setting

NOTE – when burning wood for the first time, condensation occurs and condensed fluid
leakage occurs – this is not a defect. Condensation will disappear later. When burning small
wood waste particles, it is necessary to monitor the waste gas temperature which must not
exceed 320 °C. Otherwise, the ventilator (S) may sustain damage. Wood-tar and conden-

sate formation in the hopper is a side effect of wood gasification.

ATTENTION

– during operation, all doors must be shut and the ignition valve pulling rod

must be inserted, otherwise the ventilator (S) may sustain damage.

Output regulation - electromechanical

Output regulation is achieved by means of a control flap valve /8/ operated by the FR 124 draught
regulator /22/ which automatically opens up or shuts down the valve /8/; depending on the pre-set out

­going water temperature (80 - 90 °C) (DC50SE excluded). The output (draught) regulator adjustment
should be done carefully because it not only regulates the output; but also protects the boiler against
overheating. The setting should be in compliance with the enclosed ‚Assembly and Setting Instructions‘

for the HONEYWELL Braukmann FR 124 type regulator. The overheat protection function can be
monitored by checking the regulator’s functionality at temperature of 90 °C. At this temperature, the
control valve /8/ must be almost closed. It is necessary to seek and discover the best setting. You can
visually inspect the control valve’s /8/ position by looking from the rear side of the ventilator. The ven

­tilator is controlled by a control thermostat situated on the boiler’s panel. The regulation is based on the
pre-set outgoing temperature value. The temperature set on the thermostat should be 5 °C lower than the
temperature set on the FR 124 draught regulator. (Indicated by dots on the thermostat scale). The con

­trol panel also comprises of a waste gas thermostat which is used to switch the ventilator off when the
fuel has been combusted. When igniting, position to the “firing-up” position (minimum value). When
the fuel has sufficiently flared up, set it to the operating position in which the ventilator runs until the
fuel has completely burnt out. It is necessary to seek and discover an optimal position of the thermostat;
which depends on type of fuel, chimney draught and other conditions. The outgoing water temperature
should be monitored on the thermometer /18/ situated on the control panel. There is also an irreversible
safety thermostat on the panel. Wood supply gasification boiler DC50SE is not equipped with Honey

­well draught regulator FR 124 and typical regulation valve (aperture for FR 124 on the water outlet
from the boiler must be blinded). It is equipped with regulation valve with a servo-drive and spring
placed in the combustion air inlet. This valve is controlled with regulation and waste gas thermostat in
accordance with outlet water temperature; like the draught ventilator. When the thermostat is switched
off, it switches off automatically. Regulation valve is set by the manufacturer to a maximum opening of
30 mm. Maximum valve opening can be altered as necessary. This can change the boiler output and its
combustion. Boiler DC15E is not equipped with a ventilator, regulation, waste gas and safety thermo

­stat. Output regulation is carried out only with Honeywell FR 124 draught regulator, which controls the
regulation air valve. Panel on DC15E type is equipped with a switch and thermostat for a pump.

Draught regulator - HONEYWELL Braukmann FR 124 – Assembly instructions

Disassemble the lever /1/ and coupler /2/ and screw the regulator into
the boiler.

Setting

Heat the boiler to approx. 80 °C. Set the setting handle to the tem­perature read on the boiler thermometer. Tension the air flap valve
chain in a way that provides the required boiler output; the gap at
the air (control) flap valve may range between 3 - 50 mm. The valve
minimum gap is set by a setscrew to 3 - 8 mm; boiler service-life pro­longing feature, do not decrease. Otherwise, the boiler and ventilator
may get covered in tar and their service life would be reduced. In
cases where there are insufficient general draught conditions, slightly
increase the permissible minimum gap.

Draught regulator functional check

Set the setting handle to the required temperature of water exiting the
boiler (80 - 90 °C). When the water temperature reaches its maximum
of 95 °C, the control flap valve must be fully closed (only providing
the setscrew gap). It is always necessary to fine-tune the specified op

-

erating temperature (80 - 90 °C) utilising the mixing valves behind the
boiler either manually or by electronic regulation with electric actuator.

Adjustments to settings should be done on the basis of the waste gas analyzer and maximum
temperature; which must not exceed 320 °C at the outlet to chimney, at stabilised nominal
output /with closed ignition valve/. The boiler is set to optimal operating parameters by the
manufacturer. Therefore, make adjustments to settings only in cases where the operation
conditions are non-standard (for example - if insufficient chimney draught, pull the regula­tor pulling rod to its maximum).

29. Fuel refill

Before fuelling, open the ignition valve /13/ with the pulling rod /17/. Do not switch the extraction
ventilator off. Wait for approximately 10 seconds and slowly open the loading door /2/ so that any ac­cumulated gases are first vented off into the flue-gas duct and not in the boiler room. Before opening
the DC70 door, switch the pressure ventilator /4/ off using switch /20/. Cover the glowing charcoals
with a wide log. Do not press the fuel on the gasifying nozzle, it can put the flame out. Always fill the
hopper completely. In order to prevent excessive smoke formation, load new batch of fuel only after
the previous fuel has combusted to at least one third of the loading volume.

CAUTION – during operation, the ignition valve pulling rod must be retracted, other­wise damage to the ventilator (S) will occur. Otherwise, the ventilator (S) will sustain
damage.

30. Steady heat operation

It is possible to use boilers for slow-burning operation, i.e. keeping the fire up overnight without
the necessity to heat-up during the day. This is only permitted during wintertime. This operating
method however decreases the boiler service life. Prepare the boiler for slow-burning operation in the
following way:

- place several (4 – 6) larger logs on a glowing layer of partially combusted fuel

- turn the mixing valve down
After the valve has been turned down, the boiler water temperature increases to 80 - 90 °C.

- the control flap valve /8/ operated by the FR 124 Honeywell draught regulator automatically

shuts down and the ventilator switches off (DC15E excluded) – the boiler operates in maximum
output mode

In boilers prepared as previous, the fuel burns for 8 – 12 hours. The actual slow-burn combustion
time depends on the amount of fuel placed in the boiler and on the actual quantity of consumed heat.

Even if the boiler operates in the slow-burn mode, it has to keep the output water temperature
ranging between 80 - 90 °C and returning water minimum temperature 65 °C.

31. Boiler cleaning

It is necessary to clean the boilers regularly and thoroughly every 3 to 5 days because the flue
cinder accumulated in the fuel storage tank together with tars and acids dramatically decreases the
boiler’s service life and output and insulates the heat transfer surface. If excessive amount of cinder
in the lower chamber is left to form, then the burn-off area is insufficient and damage to the ceramic
nozzle handle or the boiler may occur. Carry out the cleaning procedure by first switching the ex­traction ventilator on (except for DC15EP), then open the loading door /2/ and sweep the cinder down
through the slot into the lower chamber. Leave long pieces of wood which has not fully combusted
(charcoals) in the hopper for the next time the boiler is used. Open the cleaning lid /15/ and clean the
rear duct with a brush. If the brake valve is inserted in the duct (corrugated sheet), it must be removed
before cleaning. Remove all the soot and cinder after opening the lower lid /15/. Open the lower door
/3/ and clean the lower chamber from cinder and soot. Remove the layers of dust on the side walls of
the lower combustion chamber with a poker or a brush. If there is a roof in the lower combustion area
which contains a breaker (corrugated sheet – DC30SX, DC40SX, DC50S, DC75SE), it is necessary
to remove the breaker when cleaning and removing the ash. The cleaning interval depends on the fuel
quality (wood moisture content), heating intensity, chimney draught and other factors. We recom­mend cleaning the boilers once a week. Do not pull out the fireclay shaped piece /10/, /14/, /38/, /39/
when cleaning. At least once a year clean the extraction ventilator rotating wheel and via the cleaning
hole, inspect the state of the primary to secondary air ratio regulation. For boilers DC50SE, special
sheets are placed on the sides next to the gasification nozzles; the sheets improve the combustion
quality. Area underneath these sheets must be cleaned regularly once per 7 to 14 days. Boilers DC70S
must be checked at least 2x a year and the compressive ventilator and the air duct may need cleaning.
If necessary, clean the area behind the heating area rear screen from tars and ash /41/, /19/.

32. Heating system maintenance - including boilers

Inspect at least once every 2 weeks. If necessary, refill the system with water. If the boilers are
out of operation during wintertime, a risk of water freezing in the system arises. Therefore, we recom­mend letting all the water out from the system or fill it with an anti-freeze. In other situations, only let
water out if necessary and keep without water for as little time as possible. After the heating season
is over, clean the boiler thoroughly and replace damaged parts. Do not leave parts replacement for the
last moment; prepare your boiler for the heating season as early as Spring.

33. Use and inspections

Boiler operators must always follow the operation and maintenance instructions. Interventions
into boilers that could endanger the health of the operators or other persons in the vicinity are prohi­bited. Boilers may only be operated by a person that is more than 18 years old, that has been acquain­ted with the instructions and operation of the equipment and that complies with the requirements of

§ 14 of the Directive no. 24/1984 Coll. The boiler operation needed increased attention to safety in
terms of potential burns from hot boiler parts and systems. You must never leave unattended children
near boiler that is in operation. During the operation of solid fuel boilers it is prohibited to use any
flammable liquids for lighting the fire and it is also prohibited to increase the nominal output of the
boiler during operation (overheating). You must not put flammable objects on the boiler and near

the fuel feeding and ash pan openings and ash must be stored in non-flammable containers
with a lid. When handling fuel and ash, wear protective equipment (gloves, dust mask). Boilers in

operation must be under occasional supervision of the operator. The user may only carry out repair
consisting in simple replacement of a spare part (e.g. a sealing cord, etc.). During the operation check
the doors and cleaning openings for tightness and always tighten them properly. The user must not al­ter the structure and electric installation of boilers. The boiler must always be cleaned properly and in
time so that free passage of all the ways can be guaranteed. Cleaning doors must always be properly
closed.

CAUTION - Follow valid fire regulations and have in reach portable fire extinguisher. If
any non-standard behavior of the boiler shut down the boiler from operation and call the
service.

Heatproof shaped piece (nozzle) replacement

Material list: 1. Heatproof shaped piece

2. sealing cord (3 pcs)

3. boiler sealant (white)

Procedure: Remove or break up the old heatproof nozzle
(further referred to as „nozzle“). Thoroughly clean the noz­zle holder, which the nozzle was seated on, from tar and
old sealant. Roll slim strands of boiler sealant. Place these
continuously round the nozzle holder aperture in such a
way which would prevent any penetration of secondary air
underneath the nozzle later on. Take the new nozzle in your
hand, stand in front of the boiler and position the nozzle in such a way that its recess (cut-out) is posi­tioned in a direction away from you and downwards (the recess is positioned inside the boiler; a mark
on the nozzle - if present – is positioned backwards). The secondary air is brought to the nozzle from
the rear section of the boiler. Place the nozzle on its holder and fully push towards the rear of boiler.

Position it in such a way that free play between nozzle and holder is the same on both - the left and
right side. Shape the sealing cords with a hammer so that their cross-section changes from square to
trapezoid shape. Then spread them along the sides and front of the nozzle and by gently tapping calk
them evenly round its circumference so that they are level with the nozzle. Cover the sealing cord
connections with a small amount of the boiler sealant.

Door sealing cord replacement

Procedure: Use a screwdriver to remove the old sealing cord and to clean the groove in which it was

seated. Lightly shape the cord from a square into a trapeze cross-section using a hammer. Press the
sealing cord along the door circumference (place the narrower base into the groove first) in such a
way to ensure that the cord sticks well in the groove (if necessary use a little hammer). Position the
lock’s handle upwards, and with several gentle, careful taps of the door against the boiler, press the
cord into the groove until the door can be closed smoothly. Fine-tune the position of the wheel that
engages the lock’s cam. This is the only procedure that can ensure good door seal!

Adjusting the door hinges and locks

The loading door and ash-pan door are firmly connected to the boiler drum by two sets of hinges.
Each hinge consists of a nut, which is welded to the boiler drum, and a screw to which the door is
connected by means of a pin. If you want to adjust the hinge settings, first take off the upper hood
(control panel) and remove both pins. Then remove the door and slightly turn the screw with a right­hand thread, as necessary. By following these steps in reverse order, you can replace the door. The
door lock consists of a lever with a handle and a cam which engages a wheel that is screwed into the
boiler and secured by a nut preventing its turning.

36. Environmental protection

The ATMOS gasifying boilers comply with the most demanding environmental requirements
and were awarded the “Environmentally friendly product” mark, in compliance with directive No.
13/2002 of the Ministry of Environment of the Czech Republic. The boilers are certified in compli­ance with the European standard EN 303-5 and they fall within class 3, 4 and 5.

Disposal of the boiler after expiration of its service life

It is necessary to provide an ENVIRONMENTALLY FRIENDLY DISPOSAL of the boiler‘s individual parts.
Before disposal, clean all the flue cinder and place it in a refuse bin.
Take the boiler drum and hood to a scrap-metal collection site.
Take all the ceramic (fireclay) parts to an approved refuse site

NOTE – In order to comply with the environmentally friendly operation requirements, it
is prohibited to burn any other substances than specified for the boiler. Plastic bags, vari­ous plastic materials, paints, textiles, laminate are substances which should be particularly
avoided but also avoid burning sawdust, sediment and coal dust.
