The regulations applicable to the respective location of installation must always be complied with.

On request, we will be glad to provide you with the sources referred to for the standards and regulations listed. When on stock, we will be glad to send such to you at cost price.

3 The structural Surroundings for the Furnace

The national building regulations existing in this connection must always be complied with.

3.1 Heating room requirements

A separate and dry heating room must always be provided for the PYROT. No combustible materials may be stored in the heating room. The heating boiler may only be set up on a fire- and temperature-resistant floor. No temperature-sensitive pipes or installation lines may be installed in the floor below the heating boiler.

The load-bearing capacity of the heating room floor must be designed for the weight of the system plus filling with water and fuel. The load-bearing capacity of the floor in the area of the boiler bearing surface must be 2000kg/m². Detailed technical dimensioning is possible with data sheet no. 6010.

The minimum distance to the walls and ceiling required according to the table of dimensions for proper cleaning and maintenance of the boiler must be complied with. A sufficient supply of fresh air must be provided directly from outdoors into the heating room. Induced ventilation is necessary for heating rooms that are confined or enclosed. The temperature in the heating room must not exceed +40°C while the system is in operation (in the area approx. 1 m away from the boiler). The temperature in the heating room must not fall below +10°C while the system is in operation (inner side of exterior walls).

3.2 The chimney connection

The PYROT rotary combustion chamber boiler is equipped with an exhaust fan and thus a fireplace without a draught requirement. The design of the chimney should be carried out as for a fireplace with an oil or gas blast burner without a draught requirement (exhaust temperature at rated load of 160°C-200°C). The PYROT rotary combustion chamber boiler is output-controlled within a range from 30%-100% of the rated boiler output. This produces exhaust temperatures within a range from min. 100°C and max. 250°C. An insulated chimney should be provided to prevent the danger of sooting. The distance from the exhaust fan to the chimney should be as short as possible. 90°-elbows should be avoided if possible. Exhaust gas lines of more than 1 m in length must be insulated.

The connection to the chimney should be made such that it rises at an angle from 30°-45°. The exhaust line, incl. the lead-in into the chimney, should be executed so as to be gas-tight.

A supplementary air device (draught controller) is absolutely necessary in the chimney to provide for intended operation of the PYROT Rotation Heating System.

4 Transport and Installation

The personnel who carry out the transport have to know the dangers of accidents that might arise on doing so and prevent such through suitable measures.

Only hoist the boiler when it is entirely empty (of water, fuel and ash).

Pyrot 100 - 300 Hoist by the lifting lug.

Pyrot 400 - 540 Hoist by forward-flow and return-flow connection pieces using a cross bar.

5 Water System Installation

Customers must ensure that there is a supply of water independent of the electricity supply. This (redundant) design ensures that in case of a power failure, the boiler will be reliably cooled by the thermal run-off safety valve.

Refer furthermore to the standards and regulations listed in this document.

5.1 Safety Equipment

The safety equipment for the heating installation must be carried out by the heating engineer authorised to do so.

See Spec Sheet 5960 as an example.

5.2 Expansion

With closed expansion, the supply pressure to the expansion tank should be equal to the max. amount of the facility plus 0.2 bar.

5.3 The boiler circuit with return circuit

valve

To reliably prevent boiler corrosion through condensation of the exhaust gases, the boiler return flow temperature must in no case be below 65°C.

The PYROT rotary combustion chamber boiler is infinitely variably output-controlled. For this, it is necessary for there to be a constant flow through the boiler of the water to be heated. The boiler circuit with the boiler pump and boiler mixer must therefore be installed according to Spec Sheet

5960.

The design of the boiler circuit should be carried out such that the temperature difference between the forward flow and the return flow is equal to or less than 15°C.

The triggering of the boiler pump and boiler control valve is integrated in the control system that comes with the facility.

5.4 The extinguishing water tank

A self-triggering extinguishing device must always be installed by the furnace feed system. With regard to the assembly, refer to the spec sheets in the annex.

The functioning is carried out by means of an extinguishing valve and is not dependent on electric current. A float-type switch monitors the water level and should be electrically connected (see connection diagram).

6 Electrical Installation

6.1 Positioning the control module and control cabinet

The control module should be mounted by the installing electrical installation company at a spot easily accessible for operation. Optimum positioning of the control cabinet will allow minimisation of the length of installation lines and thus of costs.

The position of the control module and control cabinet should be selected such that the negative effect of heat radiation (front side of boiler, rear side of boiler with exhaust gas collector and exhaust gas fan as well as exhaust gas line) and interference caused by dust during cleaning will both be kept as low as possible.

The ambient temperature for the control cabinet (approx. 10 cm away from the control cabinet) should not exceed 40°C while the system is in operation. In case of doubt, preference should be given to placing the control cabinet outside the heating room near the heating room door.

6.2 Electrical connection

- Connect it according to the wiring plan, laying of the CAN-BUS wire according to data sheet

4020.

- In the area of hot parts (exhaust gas fan, exhaust gas pipe), the lines should be installed in steel pipes at an appropriate distance so as to be temperature-protected.

- The cable bushings to the motors and equipment must be executed so as to be dust-tight and provided with a strain relief.

The regulations of the local electrical utility company must be complied with.

7 Fire Protection

The fire protection regulations for wood heating systems differ from country to country.

The regulations applicable to the respective location of installation must always be complied with.

7.1 Protection against burn-back for the boiler plant

These are part of the scope of delivery for the PYROT rotary combustion chamber boiler.

7.1.1 Preventing overfilling of the fire box According to TRVB 118, a level monitor must be

installed to prevent overfilling of the fire box. The PYROT rotary combustion chamber boiler has two light barrier to monitor the embers.

7.1.2 Preventing burn-back With a sensor directly on the insertion pipe, any

danger of burn-back beginning will be detected and quickly counteracted at an early stage through boosted output (an increase in the advancing of the material).

As a result, any requirement for a protective device coming into effect is avoided, and normal operation, defined as the greatest possible degree of safety supplying heat, is adhered to.

7.1.3 The backflash safeguard (RZS) According to TRVB 118, a backflash safeguard is

required for all facilities over 150 kW. TRD 414 prescribes a continuously present isolat-

ing layer if a spark-alarm and extinguishing system is dispensed with. (TRD 414 refers primarily to remnant wood from the processing of wood and derived timber products.)

For chip materials from the forestry and sawmill sectors, the restrictions are eased in part in this connection.

The PYROT rotary combustion chamber boiler is always equipped with an isolating layer and is continuously operated with negative pressure.

As a result, according to both TRVB 118 and TRD 414, the PYROT rotary combustion chamber boiler is considered as equipped with a backflash safeguard (RZS).

7.1.4 Automatically Triggering Extinguishing System for the Furnace Feed (SLEK)

A water extinguishing system is always necessary on the feed auger. This system should reliably prevent burn-back in case of a malfunction (such as a power failure). For safety reasons and to prevent damage by flooding, connecting the extinguishing system directly to the water network is not advisable.

This extinguishing system must always be equipped with a 25-l extinguishing water tank with a float-type switch and an adjustable Danfoss extinguisher valve.

According to TRVB 118, the tank for the SLE must be equipped with a level monitoring system.

If there is a shortage of water, the PYROT rotary combustion chamber boiler will switch off automatically. In case of excess temperature, the feed auger will be flooded reliably but in a limited fashion.

The pipework for the extinguishing system must be carried out by the heating engineer according to Spec Sheet 4550.

7.2 Burn-back safeguard for the fuel supply system (RSE)

The rest of the "burn-back protection for material transport" depends on the respective requirements (location, size of the fuel storage site, material, pressure conditions & regulations), these being separate items for the scope of delivery ordered from KÖB & SCHÄFER GmbH according to the descriptions below.

We always recommend installing a rotary valve as per section 7.2.3 for the PYROT Rotation Heating System. In addition to being a safeguard against burnback, this will also prevent any penetration by air leaking in via the feed auger.

7.2.1 Automatically Triggering System for the

Material Supply System (SLE-M)

Approved in part as a variation to the shut-off valve in pressure-less fuel storage units (does not meet TRVB).

The installation of the extinguishing system must be carried out by the heating engineer according to Spec Sheet 4550.

7.2.2 The slide valve

This is approved in pressure-less fuel storage units in all cases and applies according to TRVB 118 (test certificate BV 2979/89) as a suitable safeguard against back-burn.

7.2.3 Rotary valve If remnant wood is moved into fuel storage spaces

with fans, then, in order to reduce pressure applied, at least one rotary valve is necessary to reduce pressure between the fuel storage unit and the furnace. The rotary valve is suited to reduce pressure and at the same time is considered according to TRVB 118 (test certificate BV 2979/89) as a suitable safeguard against back-burn.

Max. overpressure allowed in fuel storage unit: +500 Pa Max. negative pressure allowed in fuel storage unit: +0 Pa

7.2.4 Double rotary valve with pressure compensation system

If, due to special circumstances, any mechanically produced negative pressures or extraordinarily high overpressures are expected in the fuel storage unit, then two rotary valves must be installed in the material transport route according to the respective project plan with a pressure compensation line to the outdoors.

Max. overpressure allowed in fuel storage unit: +3000 Pa Max. negative pressure allowed in fuel storage unit: -3000 Pa

One must have the supplier of the chip suctioning system confirm the maximum pressures to be expected.

The rotary valve below the silo extraction system can become leaky due to wear of the sealing elements or through large pieces of wood that cannot be conveyed. This leakage can make it possible for low-temperature gases to flow back from the furnace into the silo.

A smoke gas alarm must be installed between the rotary valve and the silo extraction system, which, when triggered, will disconnect the system causing the negative pressure for the silo.

7.3 Fire protection for the fuel storage space

The measures necessary for this are never part of the scope of performance from KÖB Holzfeuerungen GmbH.

The conditions set by the local building authorities must be met by the operating organisation in this connection.

8 Commissioning

Only KÖB Holzfeuerungen GmbH or another trained specialist may put a newly installed facility into operation for the first time.

Before the facility is commissioned, the system must be filled with water, fuel stored for the commissioning and the installation inspected.

8.1 Filling the heating system

The first filling is usually carried out with untreated water without any chemical water treatment but definitely filtered and thus free of any suspended solids.

Pay special attention when the filling is carried out to be sure the air is carefully bled out. With difficult water conditions (high degrees of hardness, etc) and/or large volumes of water, comply with VDI Guideline 2035 "Preventing Damage through Corrosion and Scale Formation in Hot Water Heating Systems" by using appropriate measures for water treatment.

Note: The filling pressure of the cold water reserve should be approx. 0.1 bar greater than the supply pressure of the closed expansion tank.

8.2 Fuel for the commissioning

For the commissioning, dry fuel (max. W 20%) should be stored in an amount for approx. 10-24 full operating hours.

This is as follows:

PYROT 100 approx 800 kg PYROT 150 approx 1200 kg PYROT 220 approx 1500 kg PYROT 300 approx 2000 kg PYROT 400 approx 2500 kg PYROT 540 approx 3000 kg

Since the boiler plant is cold, and the residual moisture will also be drawn from the refractory concrete during the initial operation, the material to be burned for the initial operation has to be at least air dry. The heating-up process should be carried out during the first three hours at low output.

To check the functioning of the silo extraction system, not too much material to be burned should be stored so as to be able to quickly clear out the extraction system to remedy the cause of any malfunction there might be.

8.3 Inspection of the installation

Before the commissioning, the future operating organisation along with the installing companies (heating engineer & electrician) are obliged to inspect the installation for the following points:

1. Exhaust gas port connected to the exhaust gas line on the chimney.

2. Chimney completely installed with clear cross section all the way through.

3. Safety valve installed on the boiler and/or boiler forward flow.

4. Thermal run-off safety valve connected to the cold water network.

5. The sensor for the thermal run-off safety valve is situated in the dipping shell.

6. The sensor for the temperature-limiting safety switch is situated in the dipping shell.

7. The extinguishing water tank on the feed auger is filled with water.

8. The sensor for the extinguisher valve is mounted tight on the pipe for the feed auger.

9. The expansion tank is connected.

10. The conveying systems are installed between the boiler and the material storage unit.

11. The facility is filled with water.

12. Material to be burned is stored for the test operation.

13. The safety limit switch is installed on the door to the material storage site (if there is a walkthrough door).

14. The control system is connected to the power supply network.

15. The motors, switches and sensors are electrically connected.

Do not put the facility into operation overhastily without the presence of a specialist from KÖB Holzfeuerungen GmbH or another trained specialist.

In case of damage, you would lose your warranty claims.

8.4 Commissioning and handover

A competent contact person from the operating organisation's side must be present for the commissioning and handover.

The heat dissipation from the boiler plant has to be assured by the operating organisation or by the heating engineer.

The heating engineer has to confirm that an inspection of the installation has been carried out positively by handing over these signed Installation Instructions.

Complying with these Installation Instructions and also following the Operating Instructions, you will be provided with heat from wood in a safe and convenient fashion.

KÖB Holzfeuerungen GmbH thanks you for the trust you have shown in us.

These Installation Instructions should be kept near the facility on a permanent basis.

Description:

The PYROT Rotation Heating System (patent no: EP 0 905 442 B1) was developed for automatic incineration of all dry to moist wood fuels (remnant wood, pellets and forest woodchips to max. W35-40). The PYROT Rotation Heating System is characterised by high efficiencies and perfect incineration at all load levels. The PYROT Boiler Plant has been tested and approved in accordance with the latest quality criteria as per EN 303-5 Heating Boilers for solid fuels, CE-certification in accordance with European Machinery Directive with continuous quality inspection by the TÜV.

Max. forward flow temperature allowed: 100°C Max. operating pressure allowed: 3.0 bar Safety heat exchanger: Built into the boiler

How it functions:

- The feed auger conveys the material to be burned diagonally from below into the firing system. The holding devices for the burn-back sensor and the thermal extinguishing valve are situated on the conveyor pipe. Above the auger, there is a metering container with a light barrier to ascertain the level of the fuel isolating layer required according to TRD 414.

- The material to be burned is ignited automatically by an electric heat gun. The gasification of the fuel is carried out on a feed grate moved by a worm-geared motor. The ash falls in an ash bin below. An automatic de-ashing system is optional. The fire block is lined with highly refractory insulation and fired refractory concrete elements.

- The combustion gases rising from the fire block are swept up by the rotating secondary airflow brought to bear by the rotation blower and burned out completely in the round combustion chamber. The thermal energy from the combustion gases is transmitted to the boiler water in a horizontally positioned pipe-type heat exchanger. The boiler is heavily insulated, cased in an aesthetically pleasing fashion and provided with excellent access through the boiler door on the end side. On the rear side of the boiler there is a flange for an oil burner, which is closed by an insulated blank lid with an inspection window.

- A flue gas recirculation system reduces the temperature in the fire box while maintaining the highest possible degree of efficiency. This increases the service life of the uncooled refractory elements in the incineration zone. With the basic setting, the ratio of recirculated gas to fresh air is geared precisely to the material to be burned. A mechanical flow volume regulator provides a constant ratio of the quantity of recirculated gas to fresh air over the entire output range.

- The exhaust fan is specially designed for wood heating operation and is very quiet. The motor has a solid, heatresistant design with a heat dissipation hub and is spring-supported. The fan casing on the intake port turns in infinitely variable fashion. The blow-out nozzle is round. Installation is possible on the top, side or rear of the exhaust gas collector.

Included in the delivery:

- Feed auger with isolating layer, incl. extinguishing valve with dirt trap, extinguishing water container with holding device

- Fire block with feed grate

- Automatic ignition device

- Boiler with rotation combustion chamber

- Set of displacement rods

- Flue gas recirculation system

Description:

Exhaust gas de-duster 90 litres [Item no. KRT-E…-1]

The exhaust gas deduster is for minimising dust emissions and is executed as a multi-cyclone with an axial function. The deduster is completely insulated, attractively encased and provided with three lids for cleaning. The crude gas space is cleaned via the cleaning lid on the side. The clean gas chamber is cleaned via the top or rear cleaning lid (fan connection not used).

The ash container, which is provided with a trolley, connects to the deduster by quick-action fasteners and moves out simply for emptying. The exhaust fan (see description of PYROT) is mounted either on top or on the side, as desired.

Note: The exhaust gas deduster is required for the PYROT with fuels with high amounts of fine particles. (Woodworking businesses, forest woodchips with fine particles amounting to more than 4%) One ash bin comes with the system. Additional ash bins have to be ordered separately.

Pneumatic Cleaning System [Item No. KRT-W100-S] Pneumatic Cleaning System [Item No. KRT-W150-S] Pneumatic Cleaning System [Item No. KRT-W220-S] Pneumatic Cleaning System [Item No. KRT-W300-S] Pneumatic Cleaning System [Item No. KRT-W400-S] Pneumatic Cleaning System [Item No. KRT-W540-S]

The complete pipe-type heat exchanger is cleaned by periodic impulses of compressed air when in operation. The process of cleaning takes place as blasts of the various sections that follow one after the other. The detaching of the ash on the heat exchanger pipes is carried out by very short but strong pressure impulses. The detached particles are carried by the flow of gas to the de-asher, where most of them are separated off. The system is built into the rear side of the boiler. The compressor should preferably be installed at a cool spot in the heating room.

How the control system works: The number of cleaning cycles within one time unit (e.g. per hour) is adapted to the loading of the boiler. One individual, complete cleaning cycle consists of a series of pressure impulses over all the sections of the heat exchanger.

Delivery includes:

- Nozzle element integrated in the exhaust gas collector, incl. connection piece with heat dissipation plates

For use in simple solar facilities as a single control circuit for heating the domestic water in a solar domestic water heater (Art. No: WSS-...). The ECO-S1 controller is a supplementary module for the ECO-B1(2) Controller for Domestic Water Heaters. When the solar collector is warmer than the domestic water at the bottom, the solar collector heats it up (adjustable temperature difference: 2-20°C).

Further details:

- Post-flow period of the solar pump, no/yes: 0-120 sec., adjustable

according to length of line

- Maximum domestic water temperature (adjustable: 20-90°C)

- Safety: disconnection of the solar pump at a collector temperature of

140°C; reconnection at 120°C

6) Maximum water content allowed, W, (percentage by weight of the total mass)

The maximum water content allowed in the fuel when entering the furnace should be taken from the spec sheets for the furnace series. With a pre-dryer installed between the furnace and the fuel storage site, extra water content can be in the fuel stored (see specifications in reference to the order). The water content influences the maximum furnace output possible, the heat emission required to the pre-dryer and thus the maximum heat emission possible to the consumers.

7) Other information

7.1) Ash and cleaning

Untreated wood without bark has a proportion of ash less than 0.5% of the fuel mass supplied. All the specifications regarding cleaning involved are based on untreated wood with bark attached with an ash amount of 0.8%. The cleaning and maintenance involved for other wood fuels should be adapted according to the amount, the specific weight and the behaviour of the ash.

7.2) Changing fuels

A great change in fuel quality, such as bulk density, water content, dust proportion or ash content might make a manual correction of the firing parameters necessary (see Operating Manual).

8) Non-woody fuels from biomass

Non-woody fuels from biomass, such as needles, foliage, grain, straw, fruit pits, etc, are usually unsuited as fuel for trouble-free operation and thus are not approved.
