2. Design

Description

Heating with pellets with the use of the ATMOS A25 pellet burner has a lot in common with natural gas or oil heating. However, there is a difference that burning of pellets produces a certain quantity of ashes that must be removed from the burner and boiler in an interval to avoid impairment of efficiency or affecting the functionality of the burner. The ATMOS A25 pellet burner is supplied with automatic fuel ignition as standard. The assembly of the burner, external conveyor and fuel bin work completely automatically during operation and is controlled by an electronic control unit with the use of a flame sensor (photocell). In the burner body the fuel and combustion air are supplied in such a way to ensure maximum efficiency and environment-friendliness of fuel burning.

Only high-quality pellets with the diameter of 6 to 8 mm and length of 5 to 25 mm should be fed into the burner. Pellets made of soft wood without bark, called white pellets, are considered as high quality

pellets.

Ashes are normally removed from the burner through the open door once every 7 to 30 days as necessary. It is recommended to thoroughly clean the inner parts of the burner once a year; for this operation the burner should be removed from the boiler. For ideal cleaning of the combustion chamber (pot) of the burner you can use a special vacuum cleaner or a poker.

4. Safety, burner installation and commissioning

Safety and connection of the burner to the boiler

WA R NI NG - Before starting the burner you must carefully read all the provisions of this

manual. At the same time you must observe all general safety regulations for work with heating equipment resulting from the valid legislation.

• The premises where the equipment will be installed must comply with all fire protection regulations

EN

in accordance with valid standards and laws.

• The equipment must be positioned in such a way to ensure access for cleaning and removal of ashes not only from the burner, but also from the boiler, flue gas duct and chimney.

• The burner must be installed to the boiler over a sealing cord, soft Sibral sealing or another insulation and sealing material to prevent flue gas from escaping along the burner to the boiler room. Under one of the nuts with the use of which the burner is attached to the boiler a SPECIAL SHEET-METAL PART - END SWITCH STOP must be positioned. It is used to compress the end switch that monitors the proper position of the burner on the boiler. This protective device must not be omitted in any case as it is directly related to fire safety.

• The connection between the burner and the boiler must be properly tightened to prevent flue gas from escaping to the boiler room.

•

During the installation you must make sure that the pellets can freely fall through the hose to the burner. The connections between the hose, burner and conveyor must also be properly tightened.

Design and technical measures for increasing safety

• The ignition and combustion process is controlled by the electronic control unit by means of the

flame sensor - photocell. If the sensor does not sufficiently see the flame during operation, it will

automatically put the burner out of operation.

• The electronic control unit senses the speed of the burner fan and at any problems of the fan it

automatically puts the burner out of operation.

• On the burner frame there is an end switch and end switch stop that does not make it possible to

start to burner if the burner is not properly fixed to the boiler (e.g. after cleaning of the burner). If during normal operation of the burner the end switch gets disconnected, the burner will be automatically put out of operation. If at the start after two attempts with the fuel supply and one attempt without the fuel supply the pellets are not ignited, the burner will be automatically put out of operation.

• If during normal operation of the burner the fuel bin runs out of pellets, the burner will try a new

start and subsequently will be put out of operation. After replenishing pellets in the fuel bin and drawing pellets to the conveyor you can start the burner by merely turning off and on the burner switch on the boiler panel.

• The flexible transparent hose between the burner and external conveyor is made of special material

that melts at high temperatures and the hose will change to a spring that will separate the burner from the fuel bin.

10-EN

www.atmos.cz

Operation and maintenance manual - EN

• The safety thermostat - located on the fuel supply pipe of the burner, will shut down the burner if

its temperature is higher than 95 °C (55 °C for boilers DxxPX, PXxx). Thus, it protects the burner from return ignition of pellets in the conveyor and at the same time from operation with clogged flue gas exhaust from the boiler (e.g. in case of a failure to remove dust from the boiler, flue gas duct and chimney). The safety thermostat will also put the burner out of operation in case the hose between the burner and conveyor gets perforated to prevent flue gas from escaping to the boiler

room.

INFO - After any shutdown of the burner when an error message (ALARM) appears on the display it is necessary to immediately find the cause and remove it. After removing the cause of the error you can start the burner by merely turning off and on the burner switch, which is located on the boiler panel.

5. Type of environment and location of the boiler with the

burner in the boiler room

Boilers with a pellet burner may be used in the AA5/AB5 basic environment in accordance with

the ČSN3320001 standard. Boilers must be installed in a boiler room with guaranteed sufficient supply

of combustion air. It is unacceptable to locate boilers on residential premises (incl. corridors). The cross-section of the opening for supply of combustion air to the boiler room must be at least 350 cm2 for boilers with an output of 5 - 45 kW.

EN

6. Chimney

A boiler with a burner must always be connected to the chimney vent with consent of the responsible chimney maintenance company. The chimney vent must always produce sufficient draught

and exhaust flue gas to the free atmosphere in virtually all operation conditions. For proper function of boiler the separate chimney vent must be properly dimensioned as the combustion, output and service life of the boiler depends on its draught. The draught of a boiler directly depends on its cross-section, height and roughness of the inner wall. No other device may be connected to the chimney to which a boiler is connected. The diameter of the chimney must not be smaller than the outlet on the boiler (min. 150 mm). The chimney draught must achieve prescribed values (see the technical specifications in the boiler manual). However, the boiler must not be excessively high so as not to reduce the efficiency of the boiler and not to disturb its combustion (tear the flame). In case of too strong draught install a throttling flap or draught reducer in the flue gas duct between the boiler and the chimney.

Guideline values of dimensions of the chimney cross-section: 20 x 20 cm height 7 m Ø 20 cm height 8 m 15 x15cm height 11 m Ø 16 cm height 12 m

The exact determination of chimney dimensions is defined by the ČSN 73 4201 standard.

The prescribed chimney draught is specified in the “Technical data” chapter of the manual of the particular boiler.

CAUTION - The draught of the chimney during operation must ensure the minimum vacuum of 2 Pa in the combustion chamber of the boiler.

EN-13

Operation and maintenance manual - EN

7. Flue gas duct of the boiler

The flue gas duct from the boiler must lead to the chimney vent. If the boiler cannot be connected directly to the chimney vent, the corresponding flue gas duct adapter must be as short as possible with regard to the particular conditions, but not longer than 1 m, without additional heating surface and it must rise towards the chimney. Flue

EN

gas ducts must be mechanically strong and leak-proof for flue gas and cleanable inside. Flue gas ducts must not lead through other owners‘ residential or commercial units. The inner cross-section of the flue gas duct must not be larger than the inner cross-section of the smoke uptake and must not get narrower towards the chimney. The use of smoke elbows is not suitable. Designs of passages of flue gas ducts through structures of flammable materials are defined in

Annexes 2 and 3 of ČSN 061008 and are mainly suitable for

mobile units, wooden huts, etc.

INFO - In case of too strong draught of the chimney install a draught regulator (limiter) /3/ or a throttling flap in the flue gas duct, see the ATMOS price list.

8. Fire protection within the installation and use of heat appliances

Extract from ČSN 061008 - Fire safety of local appliances and sources of heat

Safe distances

On installation of an appliance the safe distance from building materials must be maintained, at least 200 mm. This distance is valid for boilers and flue gas ducts located near flammable materials of the B, C1 and C2 flammability class (the flammability class is specified in tab. no. 1). The safety distance (200 mm) must be doubled if boilers and flue gas ducts are located near flammable materials of the C3 class (see tab. no.1). The safety distance must be doubled if the flammability class of flammable material is not evidenced. The safety distance may be reduced to a half (100 mm) if you use a non-flammable heat insulating panel (asbestos panel) with the thickness of at least 5 mm, located 25 mm from the protected flammable material (flammable insulation). A shielding panel or protective screen (on the protected object) must exceed the outline of the boilers (incl. flue gas ducts) at each side by at least 150 mm and the top surface of the boiler by at least 300 mm. A shielding panel or protective screen must also be used to protect fixtures of flammable materials if the safe distance

cannot be maintained (e.g. in mobile units, huts, etc. - more details in ČSN 061008). The safety

14-EN

www.atmos.cz

Operation and maintenance manual - EN

distance must also be maintained in case of installation of fixtures near boilers. If boilers are located on a floor of flammable materials, they must be installed on a non-flammable, heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening by at least 300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat insulation pads you can use all materials of the A flammability class.

Tab. nr.1

Flammability classes of building materials and products

A - no flammability

granite, sandstone, concrete, brick, ceramic tiles, mortar, fire-resistant plastering, etc.

EN

B - difficult flammability

C1 - poor flammability

C2 - medium flammability

C3 - high flammability

WARNING - In circumstances leading to the danger of transient ingress of flammable gases or vapours and during work that might result in a temporary risk of a fire or explosion (e.g. gluing of linoleum, PVC, etc.) the boilers must be put out of operation in time before the occurrence of the danger. No objects of flammable substances may be put on the

burner and boiler in a smaller distance than the safe distance from them (more - see

ČSN EN 13501-1).

In short, do not put any items that could easily catch fire in the vicinity of the boiler.

9. Connection of boilers D14P Compact, D21P Compact, D25P Compact, with a buffer tank for burner control on the basis of TS and TV sensors

EN

INFO – The TV and TS (boiler accessory) sensors on the buffer (accumulation) tank are connected directly to the burner. The boiler does not include an extraction fan, and so it does

not requjire the AD02 or AD03 module.

Required accessories (not part of the burner): nothing needs to be bought

System configuration of parameters: S6 = 1, S14 = 0, S15 = 2

Pump in the boiler circuit is controlled via the directly installed thermoregulator from the boiler panel.

INFO - In case of we would like to control pump in the boiler circuit directly from the control unit of the ATMOS A25 burner with output R2 it is necesary to switched the reserve R2 on the boiler terminal board (from terminal 7 to terminal 10) and instal the TK sensor (boiler temperature sensor). Further set S14 parameter (S14 = 12) - pump control in the boiler circuit. After activation of this funftion, S37, S38, S39, S40 temperature parameters should be checked and configured. For boilers D14P, D14P/130, D21P a D25P Compact we recommend to set pumps in the boiler circuit to S40 = 1 (when S14 = 12) for improved operation.

Only connect the burner to the 230 V, 50 Hz electric mains via the boiler with a mains cable without a plug so that the conductors (L, N) should not be interchanged. The mains supply must be replaced with the same type by a repair organization. The boiler must be positioned in such a way

that the connector on the burner can be within the operator’s reach (in accordance with ČSN EN

60335-1).

CAUTION - Boilers with a burner may only be connected by a qualified person in accordance with all the relevant valid regulations of the particular country while great attention must be paid to safe earthing of the boiler. After the installation of the burner on the boiler the technician must connect the burner and subsequently the entire boiler to the electric mains in accordance with the attached wiring diagram.

Connection:

Between the burner and boiler a six-wire cable is newly used that is connected with one end to the burner with a 6-pin connector (part of the burner) and the other end with a 6-pin connector to the boiler.

EN

The meaning of the conductors is as follows:

Black – phase L1 (230V, 50Hz) – With the main switch of the boiler on the black conductor is

•

permanently live (independently of the control thermostat of the boiler). It is the supply voltage of the burner. This phase must be fuse protected via the safety thermostat of the boiler (95 - 110 °C).

• Brown – phase L2 (230V, 50Hz) – The brown conductor is controlled by the control or another

thermostat on the boiler panel. It brings the phase, impulse for the burner start. It is perceived as the starting (ignition) and shutdown signal. This phase must also be fuse protected via the safety thermostat of the boiler. (95 – 110 °C).

• Grey - reserve R (L3) (230V/50Hz) – The grey conductor is connected directly to the 6-pin

connector on the boiler. It serves as the free reserve for various functions of the boiler, characterized with the S6 parameter. If you do not use the reserve function, connect the supply cable directly to the connector, not connecting or cutting off the grey cable

• Red - reserve R2 (230V/50Hz) – The red conductor is connected directly to the 6-pin connector

on the boiler. It serves as the second free reserve for various functions of the boiler, characterized with the S14 parameter. If you do not use the reserve function, do not connect or cut off the red cable.

• Blue - N – Neutral – The blue conductor is connected to the neutral conductor.

• Yellow and green - PE – Protective Earthing – The yellow and green conductor is connected to

the earth.

37. Commissioning

CAUTION - The system may only be put in operation if the burner is connected to the

boiler, the boiler to a chimney with sufficient draught via a flue gas duct and in the fuel bin there is a sufficient quantity of pellets of the corresponding quality. Pellets made of soft

wood without bark, i.e. white pellets with the diameter of 6 to 8 mm and length of 5 to 25 mm are considered as high-quality pellets. These pellets do not cake. Burning of dark pellets or pellets with bark that contain visible dark dots produces cake that must be removed from the burner mouth once a day. Otherwise the combustion chamber and the feeding hose from the conveyor will get clogged.

INFO - The pellets have to be stored in dry and clean containers (areas). When filling the fuel bin, the pellets must not be contaminated by foreign objects that could cause a blockage of the conveyor or have an impact on the burning process.

Requirements for the external conveyor and pellet bin at the first start of the burner:

• The worm conveyor must be positioned in the bin in such a way to be able to easily pick up

pellets. In the case of a fuel bin whose pellet level will be higher than 2 metres a roof will have to be installed over the conveyor to prevent blocking of the conveyor. Blocking of the conveyor is caused by dust in the pellets in combination with high pressure caused by the height of the pellet level. ATMOS 250, 500 and 1000 l pellet bins do not require the installation of the roof.

EN

• The hose between the burner and conveyor must be tensioned, properly fixed and must have such

an inclination to enable trouble-free falling of pellets to the burner.

• The connector of the work conveyor must be plugged into the socket on the burner.

Procedure of drawing pellets to the conveyor

• Plug the connector of the external worm conveyor to a standard wall socket. As soon as the first

pellets get over the top point and start to fall to the burner via the elastic hose, plug the connector of the external worm conveyor back into the socket on the burner.

Normal operation:

• On the control thermostat on the boiler panel set the required operation temperature of 80 - 90 °C

and turn on the switch of the burner located on the boiler panel and the main switch. For boilers with a built-in burner in the upper doors reduce the combustion thermoregulator for heating.

The STARTup mechanism consists of the following steps:

At the start the worm conveyor and the ignition spiral are started (the fan on the burner is stopped).

•

• The worm conveyor will run for the time set by parameter T1, necessary for the delivery of the

amount for pellets for optimum ignition. After the delivery of the ignition amount of fuel the worm conveyor will stop. The burner fan will be started at the ignition speed - parameter S2 as

well as the extraction fan (if the boiler is equipped with one and is set accordingly – reserve R and parameter S6).

www.atmos.cz

EN-45

Operation and maintenance manual - EN

• After the ignition of pellets the photocell will sense light, which will cause the ignition spiral to

switch off with a slight delay.

• The burner will pass over to the stage of perfect burning of fuel - set by parameter T7.

The OPERATION algorithm consists of the following steps:

• When the fuel burns perfectly, the burner will get to the stage of gradual increase of the power

to the nominal value - parameter T10.

EN

• After achieving the nominal power the burner works in the normal mode until the heating system

or the accumulation tank is heated to the required temperature. The power of the burner results from the hourly quantity of pellets delivered by the worm conveyor to the combustion chamber. The worm conveyor works in the intermittent mode set by parameters T4 and T6. Parameters T4 and T6 are set in accordance with the instructions on page 50.

•

After setting the nominal power of the burner you must also set the amount of combustion air necessary for complete burning of fuel. This setting is performed with the air flap on the burner

fan. The exact setting should be carried out by a trained person with the use of a flue gas ana lyzer.

The burning out algorithm is designed as follows:

After the achievement of the set temperature at the boiler thermostat (e.g. 85 °C) or temperature

•

in the accumulation tank - temperature at the bottom sensor (TS), the electronic control unit of the burner will switch off the external worm conveyor. Thanks to this, the pellets in the combustion chamber will burn out. Optimal burning out of pellets in the combustion chamber is additionally supported by the operation of the burner fan for a certain time - parameter T5. After subsequent drop of the temperature of water in the boiler or discharge of the accumulation tank - temperature at the top sensor (TV), the burner will be re-started in the same way as described in the text above. If the accumulation tank is connected to a solar exchanger and activating functions for automatic optimization (switching) of sensors, parameter S15 = 3, the burner may be turned off by sensor TK instead of sensor TS.

The other algorithms are designed in the following way:

• If the first attempt for ignition with fuel supply fails, the burner will repeat the whole algorithm.

After the second unsuccessful attempt for ignition with fuel supply the burner will proceed to the third attempt during which the fuel is not supplied any longer, but only the ignition spiral is active. After this unsuccessful attempt the burner will be put out of operation as the system has probably run out of pellets or a fault has occurred.

• In case of a short-term interruption of power supply to the burner, the burner will automatically

renew its operation after performing diagnostic checks, complete burning out of pellets and a new start.

Setting the required power and combustion quality:

The required power is set with the use of parameters T4 and T6.

However, the actual power is also influenced by the diameter of pellets and angle of the conveyor. Therefore, you should keep in mind that if after setting the burner you change the angle of the conveyor or diameter of pellets, you will have to readjust the burner.

Adjust the combustion quality with the air flap of the fan in such a way that the flame tips should always end 1 to 3 cm before the opposite wall. For boilers with burner built in the upper door and the combustion length of 60 cm or greater, adjust the burner in such a way that the tip of flame ends 10 to 15 cm before the opposite wall.

You should also know that the setting of the burner is different if the boiler is equipped with an extraction fan and if the boiler does not have an extraction fan. The combustion should be precisely tuned after 30 to 60 minutes of permanent operation, best with the use of a flue gas analyst. We recommend you to adjust the burner in such a way that the surplus of O

range of 8 to 10 (12) % and the average CO content can be lower than 500 (250) mg/m operation the flue gas temperature must never drop below 130 (110) °C and rise over 250 °C (parameter S18).

INFO - As the burner is equipped with many functions (parameters), you should only set

the basic parameters that characterized the burner power - T4 and T6, the air flap.

• Parameter S4 – Fuel ignition control method …(1)

If:

a) S4 = 1…. Photocell sensing

• Parameter S6 – characterizes the first reserve R - additional output - function… (4)

The first reserve R is used mainly for controlling boiler exhaust fan (S6 = 4 )

CAUTION – In the standard setting when parameter S1 is set to 2, you can connect to the reserve terminal (approx. 566 VA). In the setting when parameter S1 is set to 4, which means that at the start both the ignition spirals are activated simultaneously, you can connect to the reserve terminal R, R2, R5 and R6 an appliance with the maximum current of 0.29 A (approx. 67 VA).

If:

a) S6 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will be closed and the reserve output will be energized. Thanks to this you can start a spare source

of energy for heating of the building as e.g. a gas, electric or oil boiler.

b) S6 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will be opened and the reserve output will not be energized. Thanks to this a signal can be sent to

an electrically backed up AB01 ATMOS GSM module controller that will send information that there is a system fault or the system is not energized. This is the opposite logic (to S6 = 1), which

means that during normal operation the reserve is energized.

c) S6 = 3…… The reserve function as the output function for the burner fan, when the reserve output is closed, is energized always when the burner fan is running (fan mode only 100 % or

OFF). This function is applied if you want the boiler fan or extraction fan in the chimney to run together with the burner fan. This function is designed for direct control of an fan directly from the burner (e.g. DxxPX, PXxx).

an appliance with the maximum current of 2.46 A

52-EN

d) S6 = 4…… The reserve function as the reversed function of the output for the burner fan, when the reserve output is off, is not energized always when the burner fan is running. This function is always activated if you connect the A25 burner with the AS25 set containing the

AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the

www.atmos.cz

Operation and maintenance manual - EN

AD02 or AD03 module under the instrument hood of the boiler and connect it electrically between the boiler terminal board and the extraction fan, see the wiring diagram.

This setting and connection with AD02 or AD03 module and special connector (jumper to main switch) is standardly used for DCxxSP, CxxSP, ACxxSP boilers with the function for automatic

start after wood is burnt out activated (AUTOSTART – S34 = 1 or S34 = 2). Boiler exhaust fan is running simultaneously with the pellet burner during the AUTOSTART function.

e) S6 = 5…… Reserve function as the output function for the Z1 ignition spiral when the reserve copies the run of the ignition spiral.

f) S6 = 6….. Cleaning function of the combustion chamber or grill (flap). If the burner is in the

normal START, RUN and STOP mode, the output is not energized. The output is only energized for the limited time T11, which continues immediately after the expiration of time T5 in the

STOP mode. It is not used with the A25 burner.

g) S6 = 7….. Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The reserve output work independently of the condition of the actual output for the external worm

conveyor. This means that if the standard output for the external conveyor gets damaged, the reserve will work independently in accordance with the same program, and therefore it can be used as a replacement for the damaged output.

EN

h) S6 = 8….. Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor (cycles between time T4 and T6). The reserve works in dependence on the status of the actual output for the external worm conveyor. This means that if the output for the external conveyor gets damaged, the reserve will be switched off automatically. This function is suitable in situations when you need to control another external conveyor that supplies (feeds) pellets from a larger distance to the main conveyor from which the pellets fall directly to the burner.

i) S6 = 9….. Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor, but with the difference that it does not cycle, but

runs permanently both during the drawing of the ignition amount and during both the times T4 and T6. Thus, the other external conveyor runs continuously and works independently of the status

of the actual output for the external worm conveyor. This means that if the output to the main external conveyor from which pellets directly fall to the burner gets damaged, the reserve will keep working independently. This function can be used in cases when you need to control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet bin at the boiler from which the main external conveyor draws pellets to supply them directly to the burner. Caution - the other external conveyor must always be controlled with an additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler.

j) S6 = 10….. Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor, but with the difference that it does not

cycle, but runs permanently both during the drawing of the ignition amount and during both the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in dependence on the status of the actual output for the external worm conveyor. This means that if

the output for the external conveyor from which pellets fall directly to the burner gets damaged, the reserve will be switched off automatically. This function is convenient in cases when you need to control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet bin at the boiler from which the main external conveyor draws pellets to supply them directly to the burner. Caution - the other external conveyor must always be controlled with an additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler. This is a similar function to S6 = 9, but with a higher degree of safety.

EN

k) S6 = 11….. Reserve function for controlling boiler exhaust fan for DCxxSP(X), CxxSP, ACxxSP boiler types when the function for automatic start after wood is burnt out is activated. This function ensures that boiler exhaust fan is running only during wood burning after the wood is burnt out. When the burner is run on pellets, the boiler exhaust fan remains switched off. This function is used if you do not need or want to use the boiler exhaust fan while the burner is running. Install the AD02 module under the instrument hood of the boiler and connect it electrically between the boiler terminal board and the extraction fan, see the wiring diagram.

WARNING – this is not a standard setting for DCxxSP(X), CxxSP, ACxxSP boilers with the function of automatic start. (AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (standard setting is S6 = 4).

l) S6 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner regulation (boiler terminal board). This function controls the pump in the boiler circuit without using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, D80P, P80, DxxPX, PXxx. Pump output must be switched to reserve R on the boiler terminal board and the TK sensor must be installed before this function can be activated. After activation, S37, S38, S39, S40 temperature parameters must be checked and configured.

m) S6 = 13…..Reserve function is the reverse output function for controlling the pump in the boiler circuit from the burner regulation (output cable from boiler with a connector – white inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.

This method of pump controlling can be used for any ATMOS pellet boiler, and is therefore recommended. AD02 or AD03 modules must be inserted and connected under the boiler hood

and the TK sensor must be installed before this function can be activated. After activation, S37, S38, S39, S40 temperature parameters must be checked and configured.

n) S6 = 14….. Reserve function for direct control of solar heating pump from the burner regulation (boiler terminal board). This function control solar pump when automatic sensor switching function is activated (S15=3), where the boiler is connected with accumulation tank equipped with solar exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected to the TSV solar panel. This function never uses AD02 or AD03 modules. After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked and configured. This function is specially designed for boilers: D14P, P14, D15P, P15, D20P, P20, D21P, P21, D25P and P25

• Parameter S15 – Operation function of the burner by the two temperatures in the accumulation

tank …(1)

a) S15 = 1… The function is off, the burner works based on the thermoregulator on the boiler panel

b) S15 = 2 …. The function is activated and the pellet burner works based on the two temperatures (sensors) in the accumulation tank – TV and TS (recommended tank volume: 500 to 1000 l).

The temperature of the bottom sensor (TS) is the temperature at which the burner is switched off

and the fuel burns out (parameter S16). The temperature of the top sensor (TV) is the temperature at which the burner is switched on again (parameter S17).

The burner screen displays the TV and TS temperatures.

c) S15 = 3 …. The function is activated and the pellet burner works based on the two temperatures

(sensors) in the accumulation tank – TV and TS (recommended tank volume: 500 to 1000 l).

The temperature of the top sensor (TV) is the temperature at which the burner is switched on again.

The temperature of the bottom sensor (TS or TK) is the temperature at which the burner is stopped.

Whether the burner is switched off based on the TS or TK sensor is decided by the temperature of

the solar panel (TSV) and the temperature in the lower part of the accumulation tank (TS), where a

solar exchange is built-in. If the solar panel can efficiently heat up water in the accumulation tank,

the burner is turned off based on the TK sensor, so that the tank can store energy from the sun.

If the energy delivered from the solar collector drops below a certain limit (temperature), the deactivation

logic of the burner is automatically switched back to be based on the TS sensor (S26 = 1).

However, it is possible to set that the switching may only occur after a certain period of time

(S29 = 2nd digit means the length of delay between switches, in hours). Another variant is to have

the burner work permanently based on the TV and TK temperatures (S26 = 0).

d) S15 = 4 …. The function is off and the burner works based on the TK temperature, protected

by the thermoregulators on the boiler panel. After this function is activated, we need to check and

possibly setup its temperature parameters S18 and S19.

CAUTION - if S15 = 2 not possible to set S6 = 14 a S14 = 14. Je-li S15 = 3 not possible to set S6 = 11, S14 = 11, S6 = 12, S14 = 12, S6 = 13, S14 = 13. Je-li S15 = 1, S15 = 4 not possible to set S14 = 14.

• Parameter S16 - Temperature of the top sensor (TV) at which the burner is started….. (60 °C)

It is the minimum temperature of water that can be reasonably utilized in the heating system.

• Parameter S17 - The temperature of the bottom sensor ((TS, or TK for S15 = 3)) at which the

burner is stopped….. (75 °C)

It is the maximum temperature of water that corresponds to requirements of the heated building and the designed heat exchangers in the system (radiators and floor heating).

CAUTION – Do not set this value too high to avoid disconnection of the safety thermostat on the boiler. Always set the control thermostat on the boiler to the maximum value (95 °C). If the control thermostat on the boiler intervenes before the burner is switched off by the signal of the TS sensor in the bottom part of the accumulation tank, the system probably finds itself in the state of hydraulic imbalance and you should check and adjust it. You can e.g. throttle the shortcut in the boiler circuit or the return line from the heating system towards the accumulation tank.

• Parameter S18 – describes the required temperature of boiler TK, which the burner is switched

off at if S15 = 4… (85 °C)

EN

• Parameter S19

- difference between TK temperature (for re-starting the burner) for S15 = 4…(5 K)

• Parameter S24 – maximum flue gas temperature... (250 °C)

If you connect a flue gas temperature sensor (TS) to the burner and in a mode of the burner this limit value is exceeded, a warning message will appear on the display. It will notify the operator of the necessity to clean the heat exchanger of the boiler or the installer of the necessity to reduce the burner power to avoid unnecessary wasting of fuel. The operation of the burner is not limited by this message in any way and to clear the message you can just switch off and on the main switch on the boiler.

a) S26 = 0…. The burner permanently works based on the upper TV sensor (activation temperature)

and via the TK sensor (deactivation temperature). The lower part of the tank permanently has enough room for energy from the solar collector (TS sensor)

b) S26=1… the burner permanently works based on the upper TV sensor (activation temperature) and the configured logic automatically takes care of switching between the middle TK sensor and lower TS sensor. Whether the burner is deactivated based on TS or TK is decided based on the temperature on the solar panel (TSV) and the temperature on the lower part of the accumulation tank (TS), where the solar exchanger is located. If the solar panel can efficiently heat up water in the accumulation tank, the burner is turned off based on the TK sensor, so that the tank can store energy from the sun.

• Parameter S17 - activation difference of function S26 = 1… (10 K)

If the temperature on the solar panel (TSV) exceeds the temperature in the lower part of the tank by the activation difference, the boiler deactivation function will be switched from the bottom TS sensor to the middle TK sensor. If a function for solar panel pump control is activated directly from the boiler regulation (S6 = 14 or S14=4), the same logic will be used to activate the solar pump.

If the temperature on the solar panel (TSV) exceeds the temperature in the lower part of the tank

by the deactivation difference, the boiler deactivation function will be switched from the middle TK sensor to the bottom TS sensor.

If a function for solar panel pump control is activated directly from the boiler regulation (S6 = 14

the TS sensor for controlling the burner based on two temperatures (sensors, S15 = 3)... (0 hours)

This function will cause the function for deactivating the burner to be switched from the middle

TK sensor to the bottom TS sensor after the time listed in parameter S29 passes, if the temperature on the solar panel TSV is lower or greater only by the deactivation difference (Parameter S28) than the temperature in the lower part of the tank where the solar exchange is located.

The set value means the number of hours, e.g.: S29 = 2 means a switch delay of 2 hours.

• Parameter S30 – is the function of the minimal operating time of the solar pump when the

conditions for its activation and then deactivation are met (function S15 = 3)… (3 min )

The set value means the number of minutes, e.g.: S30 = 3 means 3 minutes

• Parameter S31 – characterizes the required temperature TS in the lower part of the accumulation

tank where the solar exchanger is located, during the function of charging the accumulation tank by the solar collector. (function S15 = 3)… (75 °C)

Once it is reached, the solar pump will be turned off.

function of charging the accumulation tank by the solar collector (function S15 = 3)… (100 °C)

The solar pump will be turned off if it is exceeded.

• Parameter S33 – characterizes the maximum temperature TSV of the solar collector, for which

the solar pump will still remain in operation (function S15 = 3) …(115 °C)

The solar pump will be turned off if it is exceeded.

• Parameter S34 – is the function of automatically starting the pellet burner (AUTOSTART) after

the wood burns out. The function is specially created for DCxxSP(X)/(EP), CxxS, ACxxSP burners, however it may also be used for two separate boilers …. (0)

a) S34 = 0…. The automatic start function is off

b) S34 = 1…. The automatic start function is on. The pellet burner will be turned on when the

temperature of exhausts TSV drops below the set value (S36 = 80), e.g. below 80 °C

c) S34 = 2…. The automatic start function is on. The pellet burner will be turned on when two

conditions are met:

- the temperature of the boiler TK drops below the set value (S35 = 75), e.g. below 75 °C

- the temperature of exhausts TSV drops below the set value (S36 = 80), e.g. below 80 °C

62-EN

Operation and maintenance manual - EN

If the function (parameter S34) is turned on in the boiler, the following practice is used for

boilers DCxxSP(X)/(EP), CxxSP, ACxxSP:

If the boiler is burning out but the wood container still contains enough wood, we may directly

switch the boiler switch from wood to pellets.

The pellet burner will perform a DIAGNOSTIC which will be used to ascertain the current status

of the boiler (temperature of exhausts, temperature of the boiler, temperature in the accumulation tank)

If the conditions for immediate start of the burner are not met (see above), the burner will remain

on standby, where the flue exhaust fan will remain in operation (if set) so that the wood can properly finish burning (S6 = 4). AUTOSTART will start flashing on the burner screen.

If the AUTOSTART sign flashes slowly, the conditions set by the function (S34 = 1 or S34 = 2)

are not met.

If the AUTOSTART sign flashes quickly, the previous conditions are met, but the conditions set

by function (S15 = 2) are not, which means that the temperature on the accumulation tank did not drop below the value set by S16 or the regulation thermoregulator on the boiler is not activated, i.e. the end switch is not pressed (a star is not displayed on the boiler screen near the thermoregulator symbol)

If all the conditions are met, the burner will start automatically.

EN

INFO – In case of an electric outage, the burner will perform a DIAGNOSTIC and, if all conditions are met, will burn out and return to normal operation. Otherwise it will await the fulfillment of previous conditions (drop of exhaust and water temperature). If we want to use wood to heat up the boiler, it suffices to place the switch on the wood position. However, it is better to first keep the switch on the „0“ position for 10 - 15 minutes so that the burner can properly burn out. This is an ideal time to prepare the fuel for stoking.

WARNING – DCxxSP(X)/(EP), CxxSP, ACxxSP boilers do not allow you to control the solar heating function directly from the pellet burner. Additionally the TK and TSV sensors are used for measuring the temperature of the boiler and exhausts during this function.

• Parameter S35 – characterizes the limit (max.) temperature of the boiler TK, during which the

burner will automatically start during the AUTOSTART function (S34 = 2)… (75 °C)

• Parameter S36 – characterizes the limit (max.) temperature of the exhausts TSV, during which the

burner will automatically start during the AUTOSTART function (S34 = 2)… (80 °C)

WARNING – after placing the exhaust sensor TSV on a side of the burner flue pipe, the

TSV temperature is not the exact temperature of the exhausts but the difference temperature for the automatic start function. If we want to place the exhaust sensor directly on or into the flue pipe to measure the exhaust temperature precisely, it is necessary to always use a sensor with a higher heat resistance of up to 400 °C.

• Parameter S37 – characterizes the requires temperature of the boiler TK during which the pump in

the boiler circuit will be activated. This will only occur if the required temperature is reached and the boiler is in OPERATION or burn-out mode (S14=13 with modules AD02 or AD03)… (75 °C)

a) S67 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will be closed and the reserve output will be energized. Thanks to this you can start a spare source

of energy for heating of the building as e.g. a gas, electric or oil boiler.

b) S67 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will be opened and the reserve output will not be energized. Thanks to this a signal can be sent to

an electrically backed up AB01 ATMOS GSM module controller that will send information that there is a system fault or the system is not energized. This is the opposite logic (to S6 = 1), which

means that during normal operation the reserve is energized.

c) S67 = 4…… The reserve function as the reversed function of the output for the burner fan,

when the reserve output is off, is not energized always when the burner fan is running. This function is always activated if you connect the A25 burner with the AS25 set containing the

AD02 or AD03 module, which in this case controls the extraction fan of the boiler. Install the AD02 or AD03 module under the instrument hood of the boiler and connect it electrically between the boiler terminal board and the extraction fan, see the wiring diagram.

This setting and connection with AD02 or AD03 module and special connector (jumper to main switch) is standardly used for DCxxSP boilers with the function for automatic start after

EN

a) S68 = 1…. If any fault occurs in the burner and the burner is shut down, the reserve relay will be closed and the reserve output will be energized. Thanks to this you can start a spare source

of energy for heating of the building as e.g. a gas, electric or oil boiler.

b) S68 = 2….. If any fault occurs in the burner and the burner is shut down, the reserve relay will be opened and the reserve output will not be energized. Thanks to this a signal can be sent to an

electrically backed up AB01 ATMOS GSM module controller that will send information that there is a system fault or the system is not energized. This is the opposite logic (to S14 = 1), which

means that during normal operation the reserve is energized.

c) S68 = 3…… The reserve function as the output function for the burner fan, when the

reserve output is closed, is energized always when the burner fan is running (fan mode only 100 % or OFF). This function is applied if you want the boiler fan or extraction fan in the chimney to run together with the burner fan. This function is designed for direct control of an fan directly from the burner (e.g. DxxPX, PXxx).

d) S68 = 9… Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor, but with the difference that it does not cycle,

but runs permanently both during the drawing of the ignition amount and during both the times T4 and T6. Thus, the other external conveyor runs continuously and works independently

of the status of the actual output for the external worm conveyor. This means that if the output to the main external conveyor from which pellets directly fall to the burner gets damaged, the reserve will keep working independently. This function can be used in cases when you need to control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet bin at the

boiler from which the main external conveyor draws pellets to supply them directly to the burner. Caution - the other external conveyor must always be controlled with an additional level sensor

(level meter) that will maintain the level of pellets in the pellet bin at the boiler.

70-EN

e) S68 = 10….. Reserve function as the output function for the external worm conveyor, when the reserve copies the run of the external worm conveyor, but with the difference that it does not

cycle, but runs permanently both during the drawing of the ignition amount and during both the times T4 and T6. Thus, the other external conveyor runs continuously, but it works in dependence on the status of the actual output for the external worm conveyor. This means that if

the output for the external conveyor from which pellets fall directly to the burner gets damaged, the reserve will be switched off automatically. This function is convenient in cases when you need to control another external conveyor that supplies (feeds) pellets from a larger distance to a pellet bin at the boiler from which the main external conveyor draws pellets to supply them directly to the burner. Caution - the other external conveyor must always be controlled with an additional level sensor (level meter) that will maintain the level of pellets in the pellet bin at the boiler. This is a similar function to S6 = 9, but with a higher degree of safety.

S68 = 11 ….. Reserve function for controlling boiler exhaust fan for DCxxSP(X), CxxSP, ACxxSP

boiler types when the function for automatic start after wood is burnt out is activated. This function ensures that boiler exhaust fan is running only during wood burning after the wood is burnt out. When the burner is run on pellets, the boiler exhaust fan remains switched off. This function is used if you do not need or want to use the boiler exhaust fan while the burner is running. Install the AD02 module under the instrument hood of the boiler and connect it electrically between the boiler terminal board and the extraction fan, see the wiring diagram.

WARNING – this is not a standard setting for DCxxSP(X), CxxSP, ACxxSP boilers with the function of automatic start (AUTOSTART – S34 = 1 or S34 = 2) after wood is burnt out (setting is S68 = 4).

g) S68 = 12…..Reserve function for direct control of pump in the boiler circuit from the burner regulation (boiler terminal board). This function controls the pump in the boiler circuit without using AD02 or AD03 modules. This is applicable only for boilers that do not allow heating with wood (not even in emergency situations). E.g. D14P, P14, D21P, P21, D25P, P25, DxxPX, PXxx. Pump output must be switched to reserve R5 on the boiler terminal board and the TK sensor must be installed before this function can be activated. After activation, S37, S38, S39, S40 temperature parameters must be checked and configured.

EN

h) S68 = 13…..Reserve function is the reverse output function for controlling the pump in the boiler circuit from the burner regulation (output cable from boiler with a connector – white inside) via AD02 or AD03 modules. This function controls the pump in the boiler circuit using AD02 or AD03 modules ranged into a set with pump thermostat installed into the boiler panel.

This method of pump controlling can be used for any ATMOS pellet boiler, and is therefore recommended. AD02 or AD03 modules must be inserted and connected under the boiler hood

and the TK sensor must be installed before this function can be activated. After activation, S37, S38, S39, S40 temperature parameters must be checked and configured.

i) S68 = 14….. Reserve function for direct control of solar heating pump from the burner regulation (boiler terminal board). This function control solar pump when automatic sensor switching function is activated (S15 = 3), where the boiler is connected with accumulation tank equipped with solar exchanger and collectors. The system requires TV, TK, TS and solar sensors to be connected to the TSV solar panel. This function never uses AD02 or AD03 modules. After activation, S26, S27, S28, S29, S30, S31, S32, S33 temperature parameters must be checked and configured. This function is specially designed for boilers: D14P, P14, D15P, P15, D20P, P20, D21P, P21, D25P and P25

CAUTION - the direct controlling function of solar heating from pellet burner cannot be used for upper doors. This function also cannot be used when the pump is simultaneously controlled in the boiler circuit from the burner regulation (TK sensor cannot be simultaneously in boiler and accumulation tank)

S15 = 2, S15 = 4, S34 = 1, S34 = 2), solar collector temperature (S15 = 3, S6 = 14, S14 = 14))

Short explanation:

This always depends on whether the burner regulation function based on two temperatures on the accumulation tank is on or off, and whether the automatic start function after wood burns out is activated.

The default settings are S15 = 1 and S34 = 0, which means that the function for controlling the burner by two sensors is deactivated and the AUTOSTART function for DCxxSP(X)/(EP), CxxSP,

ACxxSP burns is also off. The burner is only controlled by thermoregulators on the boiler panel. The customer may connect the exhaust temperature sensors TS and TSV and the water temperature sensors TV and TK to the burner so that they only serve as information.

If we set S15 = 2, the function for regulation by two temperatures on the tank is activated and

so we connect the water tempearture sensor in the lower part of the tank TS and the water temperature sensor in the upper part of the tank TV to the clamps of the burner connector.

If we set S15 = 3, the function for regulation by two temperatures on the tank is also activated, simultaneously with the solar functions. It is thus also necessary to connect the TK sensor located in the middle of the accumulation tank between the TV and TS sensors and the TSV solar collector sensor.

If we are going to use the AUTOSTART function for boilers DCxxSP(X)/(EP), CxxSP, ACxxSP (S34 = 1 or S34 = 2), we must also connect the TK sensor as a boiler sensor and the TSV sensor as the exhaust temperature sensor.

If we are going to control the pump in the boiler circuit (recommended S14 = 12 or S14 = 13), we must always connect the TK sensor.

If no problem has been found, reset the regulation AC07X by the RESTART command.

If the system is working, but you are not satisfied with its function, proceed as follows:

Check the quality of pellets

• Heating value - whether they are really pellets made of wood or whether something has been

added to them - crumble them and smell

• Colour - caking - white pellets do not cake, dark pellets or pellets with dark dots that contain bark

EN

cake - in such a case the combustion chamber must be cleaned once a day!

If it is not enough to clean the combustion chamber once a day, the pellets contain chemicals which

do not allow pellets to be burned in the A25 burner (biologic waste). Replacement required.

• Dust in pellets - causes uneven operation of the burner and clogging of the burner hose

• Size - too small pellets - reduce the burner power (Ø 5 x 5 mm), long pellets do not fall freely to

the burner and clog the supply pipe.

Check the flue gas temperature

• It should be in the optimal range (150 ÷ 200 °С).

• If the temperature is too low, reduce the power of the burner (decrease parameter T4 and increase

T6) and reduce the quantity of combustion air or clean the boiler.

• If the temperature is too low, increase the power of the burner and quantity of combustion air

(increase parameter T4).

Check the level of pellets in the burner mouth

•

If it is too low and the burner goes out, check the flue gas temperature (see above). Reduce the quantity of combustion air or increase the quantity of supplied pellets - increase the power (increase parameter T4).

• If the pellet level in the burner mouth is too high and the burner exhibits poor combustion - produces

smoke, increase the quantity of combustion air or reduce the quantity of supplied pellets - reduce the power (decrease parameter T4).

At the start check how long it takes for combustion quality to improve - how long smoke is released from the chimney

• If smoke is released from the chimney at the start for more than 5 minutes, extend the time of

gradual increase to the nominal power (parameter T10, e.g. increase by 5min). Be careful about the setting of the air flap.

The burner regularly does not ignite at the first attempt, but always at the second one

• Extend the time for the supply of ignition fuel (parameter T1 e.g. by 10 s), extend time T2 for

ignition of pellets (e.g. to 12 minutes) or reduce the angle of the conveyor (max. 45°).

If after stopping of the burner and its burning out a lot of glowing unburnt pellets remain in the combustion chamber (mouth) of the burner

40. Maintenance and cleaning of the burner

The system for burning wooden pellets is designed in such a way to require minimum maintenance. The necessary degree of maintenance directly depends on the set power of the burner and quality of used pellets.

CAUTION - Before starting repair or maintenance work during which you will handle the burner always turn off the power supply with the main switch of the boiler or disconnect to supply cable of the burner with the connector!

Regular removal of ashes:

Burning of wooden pellets leaves approximately 1 to 2 % of ashes. In practice you will gradually find out how often the burner should be cleaned depending on the set power, intensity of heating and quality of used fuel. Before the start of cleaning you must first shut down the burner and let the fuel burn out, best by reducing the temperature on the control thermostat or by turning off the burner switch on the boiler panel. The common interval of cleaning the burner mouth and boiler varies

in the range of 7 to 30 days (after burning of 300 to 1000 kg of high-quality pellets). You should remove ashes from the burner mouth by removing the combustion chamber from the burner mouth and knocking it out. Then remove ashes from the combustion space of the boiler and clean the heat exchanger of the boiler (tube plate) as described in the boiler manual.

EN

CAUTION - Always put ashes in a closed vessel. During the removal of ashes and cleaning of the combustion chamber use means of personal protection (gloves and protective goggles).

Annual maintenance

• At least once a year you must perform a complete check, maintenance and inspection of the

burner during which the burner must be removed from the boiler.

• During this maintenance remove and wipe the photocell that senses the flame.

• Thoroughly clean the space under the combustion chamber of the burner and behind the ignition

spiral. Disassemble the inlet pipe through which pellets fall to the burner and clean it.

• Dismount the covering metal sheet of the burner mouth attached with one screw and clean the

space under it where pellets fall and burn (scrape off dust and deposits). Clean the opening through which the photocell sees the flame.

• Knock dust out of the flexible supply hose and visually check whether it is not perforated. In such

a case repair it or replace. On that occasion check the worm of the external conveyor by inspecting it from the bottom where pellets fall into the flexible hose. Check whether is it not strangled by some objects, e.g. wound strings, a piece of wood, etc. that are sometimes found in pellets.

• Then, assemble and seat everything in the boiler. Tighten all the connections.

www.atmos.cz
