POWERCHIP Operating Instructions

BS-04-00-00-00-01-BAEN

To prevent the boiler overheating, the controller reduces the heat output in certain situations. If the boiler still threatens to overheat, the controller responds according to a set of defined safety levels.

Safety level 1

BS-04-00-00-01-01-BAEN

15°C above specified temperature

The drive motor stops the fuel feed system and the flue draught fan shuts down.

Safety level 2

PH-04-00-00-01-01-BAEN

Boiler temperature above 90°C

All heating pumps and the cylinder charging pump are switched on to carry heat away from the boiler.

Safety level 3

BS-04-00-00-01-03-BAEN

Boiler temperature above 100°C

The STL (safety temperature limiter) trips and switches all boiler control functions off while the heating circulation pumps continue to run. The system remains switched off even if the boiler temperature drops back below 90 °C. The system must not be started up again until any faults have been rectified and the boiler has been checked.

Power failure

BS-04-00-00-04-01-BAEN

The controller, the flue draught fan and all circulation pumps switch off due to lack of electricity if there is a power cut. The glowing fuel bed on the grate continues burn with the natural draught of the flue. As this operating mode is not ideal, a larger amount of ash collects on the grate as well. As soon as the electricity supply is restored, the controller takes control of the heating system again.

Opening ash box or firebox door

PH-04-00-00-02-01-BAEN

 The drive motors stop feeding the boiler with fuel

 The flue draught fan switches to maximum extraction speed

 After the ash box/firebox door is closed, normal operation is resumed

On stoker duct

PH-04-00-00-03-01-BAEN

The stoker duct and feeder box are designed to be completely air-tight as far as the fire safety flap. That means that any burn-back is extinguished by lack of air. The fire safety flap is tested and approved as a burn-back prevention device. A positioner motor opens and closes the flap. Fuel delivery does not start until the flap is completely open. If the event of a fault or a power failure, the flap closes automatically of its own accord. When the boiler is in operation, the controller prevents

12

POWERCHIP Operating Instructions

On the fuel store outfeed unit burn-back into the stoker auger by replenishing the fuel. In addition, a sensor monitors the temperature in the vicinity of the stoker auger. In that way, burning fuel is continually pushed back out of the auger duct. This burn-back prevention system always functions unless the electricity supply to the boiler system is cut off.

Required in all countries

PH-04-00-00-04-01-BAEN

In addition, between the end of the fuel outfeed unit and the burn-back prevention device there is a sprinkler unit that is used instead of the temperature monitor with fuel stores with

a capacity not exceeding 50 m³

and is triggered at 55°C.

When the sprinkler is triggered, the sloping outfeed auger enclosure – which also serves as a burn-back inhibiting device

– is completely flooded. The quantity of water required to do so is at least 20 litres. If the temperature drops back below

55°C, the flooding is stopped.

Note:

The sprinkler system must be connected on all systems regardless of local regulations.

Overfill prevention

PH-04-00-00-05-01-BAEN

The overfill prevention function is triggered by the switch on the overfill cover. The fuel outfeed unit then runs in reverse for

5 seconds and then for 5 seconds forwards. If the cover switch trips again, the outfeed unit immediately stops.

Fuel stores > 50 m³

Requirement in Austria

PH-04-00-00-06-01-BAEN

A temperature monitor connected to a warning device must be installed in the fuel storeroom at the point where the fuel conveyor exits the fuel store and enters the boiler room. The warning device must be triggered when the temperature exceeds 70°C.

Manually operated fire extinguishing facility

This fire extinguishing facility is for the purpose of combating a fire seated in the fuel storeroom/bunker/silo in the area of the outfeed unit and is manually actuated. It consists of conduit piping with a minimum size of DN 20 and is to be fitted in the fuel storeroom immediately above the fuel conveyor close to its exit point through the wall or ceiling and positioned so as to obtain the maximum possible fire extinguishing effect. The conduit piping is to be connected directly to a pressurised water supply and provided with a stop tap located in the boiler room. That tap must be identified by a sign carrying the inscription "Fuel storeroom fire extinguisher". The design of the fire extinguishing facility must be such that it cannot be damaged by the delivery of fuel into the fuel store or by the fuel outfeed equipment.

On the Boiler Cascade Parameters menu (only visible on boiler "A") you can make settings for sequential boiler control.

Second boiler in the cascade system = boiler "B", third boiler = boiler "C", etc. Boiler "A" must be at address "0" on the router module, boiler "B" at 1, boiler "C" at 2, etc. After reassigning addresses on the router module, the boilers have to be disconnected entirely from the power supply. Only after that are the settings activated on the boiler.

7.6 Analogue room stat

BS-07-06-00-00-01-BAEN

If your system is fitted with an outside-temperature based heating circuit controller, each heating circuit can be equipped with an analogue room stat if desired.

The control knob on the room stat allows adjustment of the required room temperature preset on the Heating Circuit menu. Setting the control to a position in the positive range (+) raises the room temperature by up to 3°C. Setting it to a position in the negative range (–) lower lowers the room temperature by up to 3°C.

Note:

This means that the room temperature shown in the Detail View will be inaccurate. The room temperature shown will only match the actual temperature when the control knob is in the centre position. mode temperature phase, the outside temperature falls below the temperature set in the parameter

"Night OFF OT", the system heats to the room temperature set in the parameter "Night-time

Required Temperature".

Normal: Heating and low-temperature modes on as per timer programme

Heating: Continuous heating to "Required Daytime

Temperature"

Connection

- 1.5m. The most effective room is the one that is most frequently occupied. In that room, the radiators must not be fitted with thermostatic radiator valves (valves must be fully turned on).

Note:

The room stat should not be fitted in a position where it will be exposed to warm sunshine or the heat from a stove.

Pull off the control knob from the front, undo the fixing screw and remove the casing from the front.

Wire the room stat to terminals 1 and 2.

8.1 Starting up/Shutting down the system

BS-08-01-00-00-01-BAEN

BS-08-01-00-01-01-BAEN

Initial Initial commissioning and basic adjustment of the system may only be carried out by GUNTAMATIC engineers or authorised

GUNTAMATIC agents.

BS-08-01-00-02-01-BAEN

Restarting Before starting up the system again in the autumn/winter, carry out the annual check of the control and safety systems to ensure they are safe and functional. We recommend that you take out a maintenance contract so that the system operates safely and economically.

BS-08-01-00-03-01-BAEN

Day-to-day Clean the heating system precisely according to the instructions in the section Cleaning/Care. The amount of cleaning work required is heavily dependent on the quality of the fuel used and lower-quality fuels may necessitate more cleaning work.

BS-08-01-00-04-01-BAEN

Shutting down the system The system only needs to be shut down at the end of the heating season, if faults occur or in order to refill the fuel store.

To do so, set the system to the programme "OFF" and allow it to cool down for approx. 120 minutes. The system can then be shut down.

If the system is not used for extended periods (summer) also isolate it from the power supply by disconnecting the mains plug in order to prevent unnecessary lightning damage.

Checking system pressure

BS-08-02-00-00-01-BAEN

BS-08-02-00-01-01-BAEN

The operating pressure is normally between 1 bar and 2.5 bar.

If the system pressure is too low, malfunctions may result. If necessary top up the water in the heating system.

Note Completely draining and refilling the system or topping up a system filled with anti-freeze or treated water must only be carried out by a heating engineer.

Topping up the heating system water

 The heating system water must be cold when topping up

→ make sure the heating system water temperature is below 40°C.

 Add water slowly until the required system pressure is indicated on the system pressure gauge.

 Bleed the heating system.

 Check the system pressure again and add more water if necessary.

8.3 Fuel

BS-08-03-00-00-01-BAEN

To ensure trouble-free heating with the boiler, the fuel must be of the right quality.

PH-08-03-00-01-01-BAEN

Your GUNTAMATIC heating system is designed for burning

G30 woodchips with a max. moisture rating of W30, and pellets. With the optional lining for grain/miscanthus, the fuels barley, triticale and miscanthus can also be burned.

Our systems can handle fuels with a water content of up to

30% (W30). However, it does not make sense to burn fuels with a significant moisture content as a considerable proportion of the energy has to be used to evaporate the water in the fuel. The amount of ash produced in practical terms essentially depends on how clean the fuel is. With woodchips, the fine ash component increases with higher proportions of rotting wood, needles, etc.

Note:

Dust emission from the flue is related to the quality of the fuel.

Dry fuels enable substantially greater levels of efficiency.

Woodchips are made from waste wood from forestry work or from trees. After felling, chipping wood should be left to season for at least one summer in an airy and sunny location.

In sunny spots, the wood can be left lying on the ground among needles so as to make use of the moisture-absorbing effect of the needles. The wood seasoned for at least a few months is shredded into woodchips of the required size by special shredding machines.

Make sure that the average woodchip size of 3 cm (G30) is not exceeded as otherwise the auger conveyors may jam or be noisy in operation. Long thick strips of wood can cause problems on the fuel outfeed system and loss of heat output.

POWERCHIP Operating Instructions

BS-08-04-01-00-01-BAEN

There are a number of points to observe when ordering wood pellets in order to ensure that they are of perfect quality.

Reliable and trouble-free operation of the boiler and the conveying systems can only be guaranteed with high-quality pellets. Therefore we strongly advise that only quality-assured products are used that are guaranteed as such by the manufacturer.

Important quality criteria

Properties

8.4.3 Grain

Properties

 Surface should be shiny and very hard

 No additives or binding agents

 The ideal length is 20 mm

The price should always be a secondary consideration after the quality criteria. If the required quality criteria are not met, problems with combustion or conveying, increased wear and pellet consumption can result. Therefore, you should not accept quality standards that do not meet the above requirements.

PC-08-04-01-00-01-BAEN

Advanced cultivation, harvesting and storage methods combined with optimum conveying and metering qualities make grain an economical and convenient fuel.

Fundamentally, all types of feed grain are suitable. The best suited to combustion are grain types with husks and a low protein nitrogen content such as triticale. As the fusion point of grain ash (clinker formation) is around 700°C (wood ash

1200°C), it is advisable to add approx. 0.3 - 0.5% by weight of slaked lime (calcium hydroxide Ca(OH)

2

) to the fuel before use for boilers with ratings up to 50 kW and 0.5 - 0.8% for boilers with ratings over 50 kW. That increases the calcium content of the fuel, thereby raising the ash fusion point.

Note: Must not be stored with a residual moisture content of more than 13%.

The dried straw is harvested annually from the 3rd year on from April to May using a forage harvester. The crop should have a maximum moisture content of 20% when harvested.

Miscanthus has to be stored dry. As the fusion point of miscanthus ash (clinker formation) is around 900°C (wood ash

1200°C), it is advisable to add approx. 0.3 - 0.5% by weight of slaked lime (calcium hydroxide Ca(OH)

2

) to the fuel before use for boilers with ratings up to 50 kW and 0.5 - 0.8% for boilers with ratings over 50 kW. That increases the calcium content of the fuel, thereby raising the ash fusion point.

BS-08-05-00-00-01-BAEN

As a general rule, wood pellets should be stored in absolutely dry storerooms. Those rooms can be fitted with pressure-filling and air extraction pipes (Type A/110/DIN14309/G4 ½") or be provided with a filling hatch and must be fire-rated to Class

F90. The fire door must be protected by removable wooden boards. The wall opposite the pressure-filling pipe is to be protected by a blast guard. Alternatively, the pellets can be stored in fabric hoppers or plastic outdoor tanks.

Note:

If pellets come into contact with water, they swell up and disintegrate.

Therefore, the storeroom must be absolutely dry.

Refilling

Maximum bulk storage height

PH-08-06-00-01-01-BAEN

When first filling the storeroom and every time it is refilled after being completely emptied, do not immediately fill the store completely.

The fuel store must be absolutely dry; otherwise the fuel cannot be stored in it. Fill the storeroom with fuel to a depth of

50 cm, spreading it evenly over the agitator and agitator arms.

Then select the option Fill Auger from the User menu and run the agitator briefly so that the agitator arms can retract under the agitator cover plate. The fuel storeroom can then be filled up to the maximum permissible bulk storage height.

Before filling, and especially before refilling, the condition of the storeroom/remaining fuel should be examined. Residual fuel should be completely used up and/or dust removed so that old fuel and dust does not accumulate over a period of years. Broken pieces of wall or plaster and foreign objects of any kind (pieces of wood, stone, metal, etc.) can cause faults and/or damage throughout the system.

POWERCHIP Operating Instructions

the

Procedure

PH-08-08-00-00-01-BAEN

The ash boxes have to be emptied at intervals varying from every couple of days to 20 weeks depending on the amount of fuel used, its quality and heat output. The higher the ash content, the shorter the intervals at which the ash must be removed. This is especially the case with lower-quality fuels with a high ash content (e.g. bark) or a significant amount of foreign matter.

The accumulated ash obviously contains the residues of the fuel in concentrated form. If you only use environmentally safe fuels, the grate ash represents a high-quality mineral fertiliser.

Danger: Glowing embers can cause fires.

Only remove the ash from the boiler or store it in non-combustible containers.

Set the system to "Off" mode and wait until the status display changes to "Off" mode. Unlock the left grate ash box and pull it out to the front. You can then wheel the ash box easily to the emptying point by folding the handlebar upwards. The display on the boiler control panel shows the message "Burner door or ash box open (F01)".

Whenever you empty the grate ash box, please also check the fly-ash box for the heat exchanger cleaner on the right-hand side.

After emptying, replace both ash boxes and lock them in position. The message "Burner door or ash box open (F01)" disappears.

Please pay particular attention to ensuring that they are properly sealed.

On the Programme menu, set the system to the desired heating programme (Normal, Heating, etc.) and the system will start up again.

Resetting the ash warning If the ash warning appears on the display, it has to be reset on the "User" menu. To do so, go to the "User" menu and select the option "Ash emptied", change the setting to "YES" and press the "OK" button to confirm. The ash warning has now been reset to the maximum number of hours before it is next triggered. The time until the ash warning is issued is preset and can be adjusted to suit the fuel being used by selecting

"Ash Warning" on the User menu on the User Level.

9 Cleaning/Care

BS-09-00-00-00-01-BADE

BS-09-00-00-01-01-BAEN

Note:

For safety reasons you must only carry out servicing and cleaning when the heating system is switched off and disconnected from the mains, and has cooled down.

Servicing work inside the fuel storeroom must only be carried out under the supervision of a second person, who must be outside the storeroom.

There is a risk that accumulation of carbon monoxide in the fuel storeroom could endanger your life.

In particular, you should follow the safety instructions in Section 2.

BS-09-00-00-02-01-BAEN

Cleaning The sophisticated cleaning system on a GUNTAMATIC heating system means that regular cleaning work is substantially reduced. All that is required is regular emptying of the ash.

Care

The flue must be regularly swept. At the same time, the flue connecting pipe, the flue gas box and the boiler heat exchanger should be cleared of fly-ash.

Depending on how dirty the boiler becomes (which is determined by the quality of the fuel burned), interim cleaning may be required, for which the precise procedure is described in the section "Interim cleaning".

Depending on the load on the heating system, complete cleaning – for which the precise procedure is described in the section "Complete cleaning" – may be required twice a year but should be carried out at least once a year.

If the heating system is subject to exceptionally high loads, more extensive cleaning may be required.

BS-09-00-00-03-01-BAEN

If the casing panels or the controls become dirty, they are best cleaned with a soft, damp cloth. Use only gentle, solvent-free cleaners to dampen the cloth. On no account should solvents such as alcohol, white spirit or thinners be used as they will attack the surface of the boiler.

9.1 Cleaning the fuel store

BS-09-01-00-00-01-BAEN

The fuel outfeed auger and the fuel store must be completely emptied (vacuumed out) at least once every 3 years so as to prevent problems with the outfeed system due to dust accumulation.

Interim cleaning must be carried out at intervals of between 1 week and 3 months depending on the fuel burned, the quantity of fuel used and how dirty the boiler is, and involves the following steps:

1. Set the system to the programme "OFF" (see User settings) and allow it to cool down for at least 1 hour.

2. Remove ash from stepped grate (A) using a fire tool.

3. On the User menu, start the function "Clean grate" (see

Section ) and allow the stepped grate (A) to clean itself for a few minutes.

Caution: Risk of injury from moving parts.

Do not carry out any other cleaning operations while the Clean Grate function is active.

4. Clean out the air slots (D) in the grate using a small flatbladed implement such as a screwdriver (E) to clear them of combustion residue.

5. Check and clean the top air vents (B)

(only on systems with outputs > 50 kW).

6. Check that the fuel spout (C) moves freely (move up and down several times).

7. Pull out the ash boxes on the left (F) and right (G) and empty them.

8. Refit and fasten the ash boxes.

9. Unscrew the inspection cover (H) and remove the ash from underneath the grate.

10. Close and tightly reseal firebox door, ash boxes and inspection cover.

11. Reactivate boiler programme, e.g. "NORMAL".

Depending on the load on the system, complete cleaning may be required twice a year but should be carried out at least once a year.

All of the operations described in the section "Interim cleaning" are to be carried out. In addition, complete cleaning also requires the operations listed below.

1. Set the system to the programme "OFF" and allow it to cool down for at least 2 hours.

2. Unplug the flue draught fan (G), lift up and remove the cover panel (H) of the flue draught fan, unscrew the wingnuts on the flue gas box and remove the flue draught fan

(G). Lift up and remove the flue gas box adjuster plate (I).

Check the fan blade for dirt and clean if necessary.

3. Pull out the locking pin (J) of the heat exchanger cleaning mechanism and pull out the lower end plate (L) of the helix baffles by a distance of 1 cm. Open the heat exchanger inspection cover on the top of the boiler and remove the helix baffles (M) from above.

4. Clean out the heat exchanger tubes (N) using the tube brush supplied, then clean all fly-ash from the top of the heat exchanger (O) and the flue gas box (K).

5. Pull the flue gas sensor (Q) out of the flue connecting pipe, clean it and refit it.

6. Clean the oxygen sensor (P) in the flue pipe socket from the inside using a vacuum cleaner, then brush it with a fine brush and vacuum it once again. On the outside of the flue pipe socket, check that the oxygen sensor is firmly fitted (must not be loose) using a size 22 openended spanner. If the sensor is loose, carefully tighten it.

7. Carefully reassemble and refit the boiler components removed and check that all inspection covers are 100% leak-tight.

8. Reactivate boiler programme, e.g. "NORMAL".

9.4 Cleaning at end of heating season

PH-09-04-00-00-01-BAEN

If you shut down the boiler for an extended period in the summer months, complete cleaning must be carried out.

Afterwards, all metallic components of the firebox, heat exchanger and flue gas box must be sprayed with an oilbased corrosion-proofing spray.
