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, firing-up test and operator‘s training must be carried out by an installation companyt-
rained by the manufacturer; this company also fills in a boiler installation report (p.33).
2. At the gasification the tars and condensates (acids) are produced in the fuel reservoir 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 service temperature of water in the boiler must be between 80 and 90°C.
3. When using the circulating pump its run must be operated by a separate thermostat so that the
prescribed minimal temperature of the reverse water is ensured.
4. The boiler must not be permanently operated in the power range lower than 50%.
5. The boiler operation at the rated output is ecological.
6. 3.The daily firing-up in necessary in case of operation at a reduced output (the summer opera-
tion and heating the hot service water).
7. Therefore the boilers should be installed with the storage tanks and the thermoregulation valve
which guarantees 20- 30% fuel savings and a longer service life of boiler and chimney with
a more comfortable operation.
8. If you cannot connect the boiler into the accumulation you should connect the boiler with at least
one equalizer with approx. 25l volume per 1kW of 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.
The boilers with the draw-off ventilator have the letter S at the end of designation.
CAUTION - If the boiler is connected with thermoregulation valve TV 60°C and the
storage tanks (see the enclosed diagrams), the guarantee for the boiler drum is increa-
sed 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 boiler drum and ceramic fittings
can be substantially reduced due to the low-temperature corrosion. The boiler drum
can corrode within two years.

1. Purpose of use
The ecological hot water boilers ATMOS DC 50/60/70 GSX are destined for heating the one-fa-
mily houses, weekend houses, cottages and similar houses with 50 - 70 kW heat losses depending on
the type. The boilers are constructed only for combustion of the lump wood. Any dry wood, especial-
ly the wooden logs, cleft timber up to 530 mm max. length can be used for heating. It is also possible
to use the wood with a higher diameter in the form of blocks which decreases the rated output, but
prolongs the combustion time. The boiler is not destined for combustion of sawdust and petite wood
waste which only can be burnt in a small amount together with the logs- MAX.10%. Thanks to the ro-
bust hopper of the boiler there is eliminated the most toilsome operation at the wood preparation and
its cutting into appropriate pieces. It saves the physical effort and time necessary for this activity.
2. Technical specification
The boilers are constructed for combustion of wood on the principle of generator gasification
using the suction fan which exhausts the combustion products from the boiler or blasts air into the
boiler.
Suction fan - for boilers DC50GSX
DC60GSX
DC70GSX
The boiler drum is made as a weldment of steel sheets 3-8 mm. It consists of fuel hopper which
in the lower part is equipped with a refractory fitting with a longitudinal opening for the gases and
combustion products passage. The burning down space underneath is equipped with ceramic fittings.
In the rear part of boiler drum there is a vertical flue way equipped with firing-up safety valve in the
upper part. The upper part of the flue way is equipped with the draw-off throat for connection to the
chimney. The front wall is equipped with stoking door in the upper part and with the ash door in the
lower part. In the front part of the upper hood there is the tow bar (control cable) of firing-up safety
valve (register). The boiler drum from outside is heat insulated by means of rock-wool inserted under
the sheet metal covers of the boiler outer shell. In the upper part of boilers there is the control panel
for the electromechanical regulation. In the rear part of boilers there is the channel of primary and
secondary air input equipped with a register operated by the draught controller FR 124. The primary
and secondary air is preheated to a high temperature.

CAUTION – When firing up we set the flue gas thermostat to („0°C“ firing). After burn-
ing up we set the flue gas thermostat into the operating position. It is necessary to find out
the optimal position for concrete conditions. If the temperature of the combustion products
drops below the set value the thermostat switches off the draw-off ventilator. If we want the
ventilator to run again we must set a lower temperature at the flue gas thermostat (e.g. set to
„0°C“ - firing).
4. Regulation thermostat (of the boiler) – controls the ventilator operation according to the output
temperature of water from boiler.
5. Safety thermostat irreversible – it serves as a protection of the boiler against overheating in case
of the regulation thermostat failure or as the signalization of emergency temperature transgression
– after the emergency temperature transgression it must be pressed down.
6. Tow bar (control cable) of firing-up safety valve – it serves for opening the firing-up safety
valve when firing-up or stoking.
7. The place for electronic regulation of the heating system can be equipped with any regulation
which can be inserted into the opening (92x138 mm). The electric bunch is prepared for its power
supply.
8. The flue gas thermostat 2 serves for operating the flap with the servo-drive at the combustion air
inlet into the boiler according to the maximum temperature of the combustion products - the switch-
ing temperature 180-200°C (only at variant B).
The boilers advantages
The combustion in the boilers runs at the high temperatures with the function of generator gasi-
fication. This results in fuel savings and an ecological operation. The primary and secondary air of
boilers is preheated to a high temperature it means they have a hot and stable flame with a constant
quality of burning. At the GSX boilers everything runs in a ceramic combustion chamber with the
lateral primary air inlets in the upper part of the stoking chamber. The boilers are equipped with the
exhauster and they have a comfortable and easy operation. A big hopper enables to burn the cleft tim-
ber of 530mm length. Also the big pieces of wood waste can be burnt. All boilers are equipped with
the cooling loops against overheating.

6. Fuel
The prescribed fuel includes dry cleft timber and the logs of 80 - 150 mm diameter minimally
2 years old containing 12% - 20% moisture with 15-17 MJ.kg“1 fuel value. The fuel dimensions are
stated in chapter 3. „ Technical data „. It is also possible to burn the big lumps of the wood waste in
combination with the logs (max. 10%)
Basic wood burning data
The maximum output and a long service life of boiler can be ensured by burning the wood sea-
soned for minimally 2 years. In the following diagram we show the dependence of fuel value on the
water content. The effective energy content in the wood distinctly drops with increasing water con-
tent.
Example:
Wood with 20% water has the thermal value 4 kWh /lkg wood
Wood with 60% water has the thermal value 1,5kWh /lkg wood

8. The type of environment and boiler installation in the boiler-room
The boilers can be used in the „basic environ-
ment“, AA5/AB5 according to ČSN 3320001-3. The
boilers must be installed in the boiler-room with an
ensured access of air necessary for combustion. The
boilers must not be positioned in the dwelling space
(neither in corridors). The cross section of the ope-
ning for combustion air inlet into the boiler-room
must be minimum 350 cm2 in case of boilers with
35-70 kW output.
1 - Chimney
2 - Smoke-flue
3 - Boiler
We recommend that a concrete (a metal) foun-
dation is constructed under the boiler.

instruction manual - GB
GB

14-GB
9. Chimney
The connection of the appliance to the vent stack must be done with the agreement of a
competent chimney sweepers´ firm. The vent stack must always develop a sufficient draught and the
combustion products must be reliably led away into the free atmosphere for all practically possible ser-
vice conditions. For a correct function of boilers it is necessary that the separate vent stack is correctly
sized because the combustion, boiler output and service life depend on its draught. The chimney
draught depends directly on the chimney cross section, height and roughness of the internal wall. No
other appliance is allowed to join the chimney to which the boiler is connected. The chimney diameter
must not be smaller than the outlet on the boiler (min. 150 mm). The chimney draught must reach
the prescribed values (see the technical data p. 8). But it must not be extremely high so that it does not
reduce the boiler efficiency and does not disturb its combustion (does not split the flame). In case of a
strong draught install a throttle into the smoke-flue between the boiler and chimney (draught limiter).
Informative values of chimney cross section:
20 x 20 cm height 7 m
Ø 20 cm height 8 m
15x15cm height 11 m
Ø 16 cm height 12 m
ČSN 73 4201 defines the exact chimney dimensions. The prescribed chimney draught is speci
fied in section 3. „Technical data“.
10. Smoke-flue
The smoke-flue must join the vent stack. If the boiler cannot be directly connected to the vent
stack then the smoke-flue extension piece must be as short as possible,and not longer than 1 m, without
any additional heat-delivery surface and it must ascend
towards the chimney. The smoke-flues must be mecha-
nically robust and tight against the combustion products
leakage and inside cleanable. The smoke-flues must not
be led through external home or utility units. The inter-
nal cross section of the smoke-flue must not exceed the
internal cross section of the the stack flue and must not
narrow towards the chimney. The use of smoke elbows
is unsuitable. The factures of smoke-flue passing through
the structures made of of combustibles are shown in an-
nexes 2 and 3 to ČSN 061008 and are especially suitable
for the mobile facilities, timber huts etc.

11. Fire protection at the heating appliances installation and use
Selection of ČSN 061008 –Fire safety of local appliances and sources of heat
Safety distances
The minimum 200 mm safety distance from the building materials must be kept when installing
the appliances. This distance applies to the boilers and smoke-flues installed near the combustibles of
B, Cl and C2 grades (the combustibility grade is shown in table no. l). The safety distance (200mm)
must be doubled if the boiler and smoke-flues are installed near the combustibles of grade C3 (see
tab. no. l). The safety distance must be doubled in case the combustibility grade wasn’t proved. The
safety distance must be halved (100 mm) when using the fire-resistant and heat-insulating board
(asbestos plywood), with min. 5 mm thickness installed 25 mm from the protected combustible ma-
terial (combustible insulation). The shielding plate or protective screen (on the protected item) must
overreach the boiler contours incl. the smoke-flues at least by 150 mm on every side and at least by
300 mm above the upper boiler surface. Also the furnishings made of combustible materials must be
equipped with the shielding plate or protective screen if it is impossible to keep the safety distance
(e.g. in mobile facilities, weekend houses etc. – see the details in ČSN 061008). The safety distance
must be kept when installing the furnishings in the vicinity of boilers.
If the boilers are installed on the floor made of combustible materials they must be equipped
with a fire-resistant and heat-insulating pad overreaching the contours on the side of the stoke hole
and ash-pan hole (at least by 300 mm in front of the hole and at least by 100 mm on other sides. The
materials with combustibility grade A can be used as the heat-insulating, fire-resistant pads.
Table no.l
combustibility grade of building
materials and products
A - fire-resistant granite, sandstone, concretes, bricks, ceramic tiles, mortars, fire prevention plas-
ters etc.
B - uneasy to burn acumin, izomin, heraclit,lignos, boards made of basalt felt , boards made of fibre-
glasses, novodur
C1- difficult to burn hardwood(oak, beech), hobrem boards, plywood, sirkolit, werzalit, hardened
paper(umakart, ecrona)
C2- moderately combustible Softwood (pine tree, larch, spruce), chipboards, cork slabs, rubber floorings (In-
dustrial, Super)
C3- easily combustible Fibreboards (Hobra, Sololak, Sololit), cellulose materials, polyurethane, polysty-
rene, polyethylene, expanded PVC
ATTENTION - Under the circumstances that result in the danger of temporary intrusion of
combustible gases or vapours and at the activities that might result in the temporary danger
of fire or explosion (e.g. linoleum, PVC gluing etc.) the boiler must be put out of operation
in a timely manner it means before the danger occurence. Do not put any items made of
combustible materials on the boiler neither within the distance smaller than the safety
distance (more ČSN EN 13501-1).

thout plug. This is the mains feeder type M and in case of an exchange it must be replaced by the same
type (cross-section). The position of the appliance must ensure that the plug (connector) is within the
operators´ easy reach (according to ČSN EN 60335-1). Only the persons competent according to all
valid rules of the concrete country are allowed to connect the boilers.

16. Selection and the way of connection of regulation and heat-
ing elements
The boilers are delivered to the customer with the basic boiler output regulation which meets the
demands on the heating comfort and its safety. The regulation ensures the required temperature of the
output water from the boiler (80-90°C). It does not deal with the mixing valves and pumps operation.
Every pump in the system must always be operated by a separate thermostat in order to avoid the bo-
iler chilling below 65°C at the reverse path. When the boiler is connected without the storage tank or
equalizer the pump positioned in the heated facilities circuit must be switched by means of a separate
thermostat or electronic regulation so that it only runs when the pump in the boiler circuit is running.
If we use two thermostats, each for switching one pump, we set the value of 80°C on the thermostat
which switches the pump in the heated facilities circuit and the value of 75°C on the thermostat which
switches the pump in the boiler circuit. Both pumps can also be switched by one thermostat. In case the
boiler is connected with the storage tanks and the gravity water circulation is well functioning in the
boiler circuit thus prolonging the boiler start time to the required temperature we suggest to switch the
pump in the boiler circuit by means of the flue gas thermostat installed in the boiler (at firing-up). When
switching the pump in the boiler circuit by means of the flue gas thermostat installed on the boiler panel
the safety thermostat on 95°C pump should be installed in the boiler (see the wiring diagrams). The
thermostat in the boiler can be alternatively substituted by a surface thermostat at the boiler outlet which
switches the pump in the boiler circuit at 95°C (parallel- connected with the flue gas thermostat).
The required temperature of water to the facilities is always set by means of three-way mixing
valve. The mixing valve can either be operated manually or by means of electronic regulation which
contributes to a more comfortable and economical operation of the heating system. The connection
of all elements is always proposed by the designer according to the specific conditions of the heating
system. The electric installation connected with a sufficient boilers equipment with above mentioned
elements must be carried out by a specialist according to valid ČSN EN.
When installing the boiler we suggest the use of an open expansion tank, but it also
can be closed if it is allowed by the valid standards of a given country. The boiler must
always be installed so that it cannot be overheated or damaged in case of the electricity
outage, because the boiler has certain inertia.
The boiler can be protected against overheating in several ways: by connecting the
cooling loop against overheating with TS 130 3/4 A (95°C) valve or WATTS STS 20
(97°C) to the water main. In case of a private well we can protect the boiler by using
the standby source of electricity (battery with a converter) for backing up the operati-
on of at least one pump. The boiler connection with the after-cooling reservoir and the
inverse zone valve is another possibility.
When installing the boiler please underlay the rear part of boiler by 10 mm to be better
flushed and vented.
The regulators of following firms are recommended for the heating system regulation:
a) ATMOS ACD 01 - the set of equithermal regulation for solid fuel boilers
b) KOMEXTHERM, Praha tel.: [phone]
c) KTR, Uherský Brod tel.: [phone]
d) Landis & Staefa tel.: [phone]

17. Boiler corrosion prevention
The boiler connection with the thermoregulation valve is the prescribed solution which enables
to create the separated boiler and heating (primary and secondary) circuits in order to ensure the
minimum 65°C temperature of the reverse water to the boiler. The higher is the temperature of
the reverse water to the boiler the less tars and acids will condense and damage the boiler drum. The
temperature of the outlet water from the boiler must be permanently in the range of 80 - 90°C.
The temperature of the combustion products (flue gases) during the routine operation must not drop
below 110°C. A low temperature of the combustion products will cause the condensation of tars and
acids though the outlet water temperature (80 - 90°C) and the temperature of water returning into the
boiler (65°C) are kept. These situations can occur in case of heating the service water (TUV) by the
boiler in the summer season or when heating only a part of facilities. In such a case either the boiler
connection with the storage reservoirs or daily firing-up are suggested. For 15-100 kW outputs it is
possible to use the three-way mixing valve with the servo-drive and electronic regulation in order to
hold the minimal temperature (65-75°C) of the reverse water to the boiler.

19. Thermoregulation valve
The thermoregulation valve type TV 60°C or TV 65°C is
used at solid fuel boilers. At+ 60°C water temperature in
the boiler the thermoregulation valve opens and the liquid
from the heated facilities circuit (2) is let into the boiler
circuit(3—>1). The inlets 1 and 3 are permanently opened.
The minimum temperature of the reverse water to the boiler
is ensured in this way. In case of need it is possible to use
the thermoregulation valve set to a higher temperature (e.g.
72°C).
Recommended size of the thermoregulation valve
For boilers: DC50GSX, DC60GSX, DC70GSX ................................................................. DN40, DN50
20. System operation with storage tanks
After firing-up the boiler and at full output operation (with 2 - 4 loadings) we charge the existing
volume of storage tanks to the required 90-100°C temperature and then we let the boiler burn down.
Hereafter we only take off the heat from the reservoir by means of a three-way valve during the time
that corresponds to the size of the accumulator and the outdoor temperature. In the heating season
(while observing the minimum volumes of accumulators-see the table) it might last for 1-3 days. If
we cannot use the accumulation we recommend at least one reservoir of 1000l volume for equalizing
the start and finish of the boiler.
