WE HOPE YOU WILL BE SATISFIED WITH OUR PROD-
UCT, AND WE RECOMMEND TO COMPLY WITH THESE
MAIN REGULATIONS NECESSARY FOR LONG SERVICE
LIFE AND CORRECT FUNCTION OF THE BOILER
1. Assembly, ring-up test and operator‘s training must be carried out by an installation compa-
ny trained by the manufacturer; this company also lls in a boiler installation report (p. 37).
2. At the gasication process the wood tars and condensates (acids) are produced in the fuel re-
servoir therefore the thermoregulation valve must be installed behind the boiler in order to keep
the minimum 65 °C temperature of the water returning to the boiler.
The operating temperature of water in the boiler must be between 80 and 90 °C.
3. Every circulating pump in the system must be regulated by an individual thermostat in order to
keep the specied 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 operation at the rated output is ecological.
6. When operating the boiler in a lower output mode (summer operation or heating up domestic hot
water (DHW)), it is necessary to re-up daily.
7. Therefore the boilers should be installed with the accumulation tanks and Laddomat 21/22
which guarantees 20 - 30 % fuel savings and a longer service life of boiler and chimney with
a more comfortable operation.
8. If you cannot install the boiler into an accumulation system, then we recommend installing it at
least with one buffer 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 – with a higher moisture the boiler output boiler
decreases and the fuel consumption increases.
CAUTION - If the boiler is connected with Laddomat 21/22 or with thermoregulation
valve TV 60 °C and the accumulation tanks (see the enclosed diagrams), the guarantee
for the boiler body is increased from 24 to 36 months. The guarantee for other parts
does not change. In case these principles are not adhered to the service life of the boi-
ler body and ceramic ttingscan be substantially reduced due to the low-temperature
corrosion. The boiler body can corrode within two years.
CAUTION - INSTALLER SHOULD ALWAYS COMPLY WITH LOCAL PLAN-
NING AND BUILDING REQUIREMENTS.

1. Intended use
The environmentally friendly boilers ATMOS are designed for heating family houses, cottages,
holiday houses and other similar buildings. Boilers are suitable for buildings with heat loss ranging
between 19, 25, 29.8, 40 and 49 kW, depending on type. The boilers are constructed mainly for bur-
ning logs. Any type of dry wood is suitable for heating, especially wooden logs up to a maximum
length 330 - 530 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-rewood.
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 specications
The boilers are designed for burning wood based on generator gasication principle utilising an
exhaust fan, which suck out the ue gas from the boiler.
The boiler body is manufactured as a welded structure from 3 - 6 mm thick steel sheets. Consist
of the fuel hopper which at the lower end of this hopper comprises a heatproof shaped piece (nozzle)
with longitudinal opening (slot) for passing of combustion products and gases and heat proof shaped
piece at the sides. The burn out (bottom) chamber is equipped with ceramic shaped pieces (spherical
space). There is a vertical ue 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 ue 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’ body 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 tted with a control val-
ve, which is operated by FR 124 draught regulator. Primary and secondary air is preheated to high
temperature.
Boiler construction has following advantages
The combustion process proceeds to the function generator gasication at high temperatures. The
boilers called GD are provide with the ceramic re chamber and with the primary air inlets on the
sides.
EXHAUST FAN = COMFORT OPERATION
The boilers pre-heat the primary and secondary air to a high temperature which results in warm
and stable ame of stable burning quality.
Large fuel hopper allows burning of the log pieces with the maximum length 330 - 530 mm, de-
pending on the boiler type. Large pieces of waste wood can also be burned.
All boilers are equipped with cooling loop for overheating protection.

Control elements function:
1. 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 (100 °C). If
such exceeding occurs, it is then necessary to depress the thermostat.
2. Thermometer – monitors the temperature of water exiting the boiler.
3. Main switch – allows for completely shutting down boiler if necessary.
4. Flue gas thermostat – is used to switch off the ventilator when the fuel has burnt out.
CAUTION – when ring up (igniting), set the ue gas thermostat to (“0 °C“- ring-up).
After aring up, set the ue gas thermostat to „operation“. It is necessary to detect the op-
timal operating position. Should the ue 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 ue gas thermostat (set to “0 °C“ - ring-up).
5. Control thermostat (boiler) – controls the boiler operation depending on the temperature of
water exiting the boiler (80 - 90 °C).
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 ts into an aperture of (92x138 mm). The electric harness is prefabricated and ready
to be used for the regulation’s power supply.

6. Fuel
Specied fuel is dry chopped log re 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 - 530 mm as per boiler type. Fuel dimensi-
ons 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 specied in Czech standard
ČSN3320001. Boilers must be placed in a boiler
room with sufcient air access necessary for com-
bustion. Placing boilers in living areas (including
halls) is not permitted. The combustion air inlet
aperture in the boiler room must be of minimum
250 cm2 for boilers of 15 - 75 kW outputs.

2 - Flue duct
3 - Boiler

GB
www.atmos.cz GB-13
Instruction manual - GB
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
sufcient draught and it must discharge the ue 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 inuences 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 out-
let (min. 150 mm). The chimney draught must comply with the specied 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 ame “breaks”). In case of excessive draught, install a throttle
valve in the ue 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 standard ČSN EN 73 4201.
Specied chimney draught is stated in section 3 „Technical Data“.
10. Flue-gas duct
The ue-gas duct must be connected into the chimney vent stack. If the boiler cannot be connec-
ted to the chimney directly, the appropriate ue-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 ue-gas ducts must
not be lead through another person‘s apartment or property. The
internal diameter of the ue-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 ue-gas duct entries through
ammable material structures are stipulated in appendices 2 and
3 of the Czech standard ČSN 061008. These are appropriate for
mobile installations, wooden cottages etc.

11. Fire prevention during installation and use of heating app-
liances
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 ue-gas ducts positioned near ammable materials of the B, C1
and C2 ammability class materials (the ammability classes are listed in chart 1). It is necessary to
double the 200 mm safe distance if the boilers and ue-gas ducts are placed near ammable materials
of C3 class (see chart 1). It is also necessary to double the safe distance if the ammability 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 ammable insulation). The scree-
ning board or protection screen (on the protected object) must exceed the boiler outline including its
ue-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 xtures and ttings from combustible
materials in cases where the safe distance cannot be maintained (such as in mobile structures or woo-
den cottages etc. - for more details see ČSN 061008 standard). The safe distance must be maintained
even when placing xtures and ttings near the boilers.
If boilers are placed on oors from combustible materials, the oor must be tted 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 am-
mability 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 ammable gases or fumes, or
during works when a temporary re 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 ammable materials may be placed on the boilers or near
them for a distance lower than the specied 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 qualied 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 xed 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 qualied repair according to applicable standards and regulations.

CAUTION – the boiler must be installed in compliance with a design prepared in ad-
vance. Installation may only be carried out by persons trained by the manufacturer.
15. Choice and connection method of control and heating elements
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 tem-
perature of the water exiting the boiler (80 - 90 °C) is adhered to. The control of mixing valves and
pumps is not solved. 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 ue gas thermostat built in the boiler (during re-up), if the boiler is
connected with the accumulation tanks and Laddomat 21/22 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 ue 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 boi-
ler 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 ue 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

Instruction manual - GB
contributes to a more convenient and economical operation of the heating system. The connection
of all the elements is designed to suit specic 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 specic 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 over-
heat 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 addi-
tionally 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]
16. Boiler corrosion protection
The specied solution is connecting the boiler with Laddomat 21/22 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 (ue
gas) temperature must not drop below 110 °C during normal operation. Low ue gas temperature
causes condensation of tars and acids even when the specied 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 ring-
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 regu-
lation.
