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, dry heating room must always be provided for the PYRTEC Grate Firing System. 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 lines may be installed in the floor beneath 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 2500kg/m². Detailed technical dimensioning is possible with data sheet no. 7010. 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 PYRTEC Grate Firing System 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 PYRTEC Grate Firing System is outputcontrolled within a range from 25%-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 possib le. 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.

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).

Hoist by both lifting lugs simultaneously, with a max. spread angle of 45°. Otherwise use a load spreader.

Page 6

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 6960 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 PYRTEC Grate Firing System 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 6960.

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 cabinet

The control cabinet with the control panel should be installed by the installing electrical company at a place easily accessible for control.

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

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

- This should be carried out according to the terminal connection diagram. The terminal connection diagram is located on the inside of the door of the control cabinet that comes with the facility.

- 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 PYRTEC Grate Firing System.

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 PYRTEC Grate Firing System has a 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 PYRTEC Grate Firing System is always equipped with an isolating layer and is continuously operated with negative pressure.

As a result, according to both TRVB 118 a nd TRD 414, the PYRTEC Grate Firing System 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 PYRTEC Grate Firing System 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.

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.

Page 8

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 & SCHÄFER GmbH.

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

8 Commissioning

Only KÖB & SCHÄFER 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:

PYRTEC 530 approx. 3000 kg PYRTEC 720 approx. 4000 kg PYRTEC 950 approx. 5300 kg PYRTEC 1250 approx. 6800 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.

Page 9

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 & SCHÄFER 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 & SCHÄFER GmbH thanks you for the trust you have shown in us.

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

The PYRTEC grate firing system has been designed for automatically burning all dry to wet wood fuels (waste wood, pellets, wood chips, up to max. W50) and combines in the best way possible the benefits of underfeed firing with the benefits of grate firing. The PYRTEC grate firing system is characterized by highest efficiencies and perfect combustion in all load stages. The PYRTEC has been tested and approved in accordance with the latest quality criteria in compliance with EN 303-5 heating boilers for solid fuels, CE certification as per European Machinery Directive and continuous quality assurance by TÜV.

Max. flow temperature: 100°C Max. operating pressure: 6.0 bar Safety heat exchanger: Built in the boiler & ready for use

Function:

- The solid, powerful and heat-resistant feed auger moves the fuel over the burner trough into the descending and into the grate zone, which drops down and travels. Situated on the conveyor pipe are the holding devices both for the burn-back sensor and for the thermal extinguishing valve. Above the auger there is the metering container with a light barrier for setting the level for the fuel isolating layer required according to TRD 414.

- The fuel is either ignited manually or automatically with an electric hot-air fan (separate price item). The tried-andtested burner trough, the descending external grate and the moving burn-out grate made from highly-refractory cast steel (material no.: 1.4823; approx. 12 mm) allow excellent performance control and highest safety against burn-back in conjunction with automatic de-ashing system (separate price item) to be achieved for the combustion chamber. The solid, horizontally positioned and large-volume firing block has been optimised in terms of incineration, consists of a high-quality fireclay brick lining and is multiply insulated for the lowest possible surface temperatures.

In the lower part, the primary airflow is supplied to the incineration grates via a supply air fan in an output-controlled

fashion and pre-heated.

- In the upper part of the firing block, the secondary airflow is blown into the gas space of the firing system by an output-controlled fan via an encircling ring with high turbulence via individually adjustable nozzles.

This mixes the fuel gases with fresh secondary air for complete burning. The firebox door is solidly constructed, air-cooled and very well insulated. Opening the firebox door with its solid

double-knuckle hinges is an ideal solution for maintenance purposes.

The heat energy from the fuel gases is transferred to the boiler water in the horizontal shell-and-tube heat

exchangers.

The boiler is well insulated, possesses attractive cladding and is highly accessible through the boiler door on the front.

The insulated boiler door also allows a pneumatic cleaner to be installed (separate price item).

- The exhaust gas fan has been specially designed for burning wood and is very quiet. The spring-suspended motor possesses a solid, heat-resistant design with heat dissipation hub. The fan housing on the intake port rotates infinitely variably, and the blow-out nozzle is round. It is usually mounted on the exhaust gas deduster (separate price item).

Includes:

- Feed auger with isolating layer, including extinguishing valve with dirt collector, container with bracket for extinguishing water

- Fire block with burner trough, descending external grate and moving burn-out grate

- Boiler with horizontal shell-and-tube heat exchangers

- Exhaust gas fan

- Accessories: counter flange, including screws and seals, cleaning device

Preparation System for De-ashing [Item No: KPT-AV]

The trough for later accommodation of the de-ashing auger is covered by fireclay bricks. The ash is removed manually via the fire box door.

De-ashing into ash bin, 240 litres [Item No. KPT-A2-S] De-ashing into ash skip, 800 litres [Item No. KPT-A8-S]

The PYRTEC's moving grate conveys the burnt-out ash into an ash trough recessed deep in the fireclay floor. From there the ash is extracted from the furnace by an auger made of heat-resistant steel. An additional ascending conveyor auger moves the ash into large-volume ash containers. The galvanised ash containers connect easily to the ash station by quick-action fasteners and move on rollers.

Function of the control system: The level of the ash trough is monitored by a light barrier. When the level is exceeded, a certain amount of ash is carried off into the container. Continuous operation can be switched to for cleaning purposes when the furnace is shut down.

The following items come with the system:

- Fire box auger made of heat-resistant steel

- Ascending conveyor auger with container station

- Ash bin or ash skip

- Triggering system for the auger drives

- Infrared light barrier level monitoring system for ash in fire box

Pneumatic cleaning system [Item No. KPT-W720-S] Pneumatic cleaning system [Item No. KPT-W1250-S]

The complete pipe-type heat exchanger is cleaned off by periodic blasts of compressed air while the system is in regular operation. The process of cleaning itself takes place in blasting of the individual sections carried out one after another. The ash on the heat exchanger pipes is detached by very short but strong blasts of pressure.

The particles detached are conducted by the flow of gas to the de-duster, where most are eliminated.

The system is built into the furnace door.

The compressor should preferably be installed in a cool spot in the heating room.

Function of the control system: The number of cleaning cycles within one unit of time (e.g. per hour) is adjusted according to the loading of the furnace. One single, complete cleaning cycle consists of one sequence of blasts over all the sections of the heat exchanger.

The following items come with the system:

- Nozzle element built into the furnace door, incl. connecting piece with heat dissipation plate

- Compressed air distributor with tank and valves; with heat-resistant hoses connected to nozzle element

- Compressor; model 362-100, special-purpose design for municipal uses

Set of displacement rods [Item No. KPT-V720] Set of displacement rods [Item No. KPT-V1250]

Installing the displacement rods in the heat exchanger pipes produces better heat transmission and thus lowering to a great degree of the exhaust gas temperature. The displacement rods are advisable for fuels with water content less than W40 and when the furnace is used to cover the base load.

Recommendation: only use with a pneumatic cleaning system.

Function: Exhaust gas is mixed into the combustion air. This increases the proportion of gases not involved in the incineration (nitrogen N

and carbon dioxide CO2), with the effect of lowering the fire box temperature. This in turn enables, on the one hand, maximum efficiencies with a low amount of excess air with dry fuels and, on the other hand, the incineration of fuels that tend to form slag.

The following items come with the system:

- Recirculated flue gas fan with a heat-resistant design instead of the two primary airflow fans

- Suction line between furnace outlet and recirculated flue gas fan made of heat-resistant steel no: 1.4401

Incl. valves for regulating fresh air/recirculated gas

- Pressure lines from the recirculated flue gas fan to the firing block

Incl. valves for splitting up the recirculated gas/air mixture to the internal and external grates The two primary air fans for the standard design are omitted.

- Software component in the control system To be carried out by the customer:

PYRTEC Double-unit System

The Mastercontrol control system (see Spec Sheet 7850) is mandatory for the installation of a PYRTEC doubleunit system.

The PYRTEC double-unit system is a heat-generating facility, in which the load allocated to the biomass is distributed to two PYRTEC boilers. The entire thermal load generated is conducted to a joint accumulator in the form of a hydraulic switcher. It is necessary to comply with the following for this type of system:

1. Joint fuelling system: Mastercontrol The control of the joint fuelling system for the PYRTEC double-unit system is carried out by the Mastercontrol control

system. The control system components for the fuelling system are included in the articles for the various loader systems.

2. Additional heat generators: Mastercontrol Extensions for controlling additional heat generators are only allowed in the Mastercontrol (additional control cabinet)

and not in the individual boiler control system (PYR-530/ -720/ -950/ -1250).

3. PYRTEC Ecotronic control system, as an individual boiler control system Only the extensions listed in Spec Sheet 7850 are possible in the Mastercontrol control system.

The PYRTEC double-unit system is not designed to control heat consumers. (Such control is carried out by customerprovided building instrumentation and control equipment.) Using a Mastercontrol turns the PYRTEC Ecotronic control system into an individual boiler control system, without any further extensions being possible.

2005-10-01_E

A prerequisite for approval is the express permission for such by the public authority responsible. For claims to the warranty according to Section 11 of our General Terms and Conditions of Delivery, wood fuels have to meet the following conditions. If those conditions are not met, then approval is possible with restrictions (warranty, maintenance, operational safety) with a written statement by the manufacturer in reference to the facility.

1) Non-combustible substances contained

No wood fuels may contain any foreign bodies, such as pieces of metal, stones, masonry remnants or plastics. Nor must the following limits (per kg of dry fuel) for non-combustible substances contained (ash analysed at a temperature of 815°C) be exceeded or fallen short of: Limit Comparison with untreated forest wood

1.1) Chlorine Cl: max. 300 mg/kg 10 mg/kg

1.2) Sulphur S: max. 1000 mg/kg

120 mg/kg

1.3) Total Cl, S: max. 1000 mg/kg 130 mg/kg

1.4) Ash content, total: max. 15.0 g/kg 5.0 g/kg

1.5) Alkali oxides in the ash (K

O and Na2O): max. 1.0 g/kg 0.35 g/kg

1.6) Sintering point of the ash: min. 1000°C approx. 1200°C Consequence of substantial overstepping of limits (1.1, 1.2, 1.3, 1.5, 1.6): a) Hot-gas corrosion in the heat exchanger → Special maintenance instructions for heat exchanger → Shortened service life of heat exchanger b) Early sintering and melting of the ash → Special maintenance instructions for firing, → Increased maintenance costs (firing, boiler door) If the maintenance instructions are not followed, a process will be created that builds up in a negative fashion with: → Cinders change the airflow → Temperature peaks → more slag → etc, until there is fast destruction of the refractory materials

1.7) Additives in remnant and used wood: Free of heavy metals and halogen compounds

2) Superfines & dust (wood particles smaller than 1.0 mm as per ÖNORM M 7133)

2.1) Without pre-dryer, max. 10.0% of the total mass; consequence of substantial overstepping of limit: Temperature peaks → Slag formation → Even higher temperature → etc, to the point of destruction; → Special maintenance instructions for firing; Elevated values are especially critical for remnant wood in combination with elevated values as per 1.1, 1.2

2.2) For forest wood chips with pre-dryer, max 4.0% of the total mass; consequence of substantial overstepping of

limit: → Moving the exhaust air lines → Special maintenance instructions for cleaning exhaust air line

3) Origin and treatment

3.1) Forest wood and plantation wood (complete trees and trunk wood untreated)

Mature wood from trunks and branches, untreated, chopped as billet wood or chips

3.2) Compressed wood, pellets (conforming to standards, such as: ÖNORM M 7135)

Untreated wood with limited bark content, compressed by machine and calibrated

3.2) Increased proportion of bark, tree cuttings from roadside trees (untreated)

Remnants from the forestry and sawmill industries or from conservation of the countryside (elevated ash content).

3.3) Remnants from derived timber products

Usually a mixture of untreated and treated wood in the form of shavings from processing machinery and chips from choppers that run slowly. In cases of elevated proportions of dust and/or limited storage volumes, these shavings are compressed into briquettes.

3.4) Used wood

This is essentially untreated wood that has been used prior to its energetic utilisation (e.g. pallets). It is reduced in size by shredders for thermal utilisation. The metal parts have to be removed afterwards (by magnetic separators).

4) Particle size: adjustment of the conveyor augers

4.1) G30/G50 chips from untreated wood as per ÖNORM M 7133:

made by fast-running and cutting tools; max. coarse fraction with cross-section and length G 30 of 20% max. 3 cm

max. 8.5 cm;

G 50 of 20% max. 5 cm

max. 12 cm; Required cross-sections of the loading: depends on the boiler output: up to 150 kW up to 500 kW from 500 kW Conveyor auger D min. 12 cm; min. 15 cm; min. 20 cm Drop cross-section A min. 175 cm2 min. 300 cm2 min. 600 cm

4.2) Chips not from the forest; origin as per 3.2, 3.3, 3.4; briquettes, origin as per 3.3

Size essentially as per ÖNORM M 7133 G50, additionally, however:

- Fraction of one-offs max. 5% with cross-section of max. 5 cm² up to a length of max. 16 cm

- Frayed surface by chopping tools (shredders) or slow-running choppers

- Briquettes, diameter max. D 60 mm (hydraulic compressors, pressure geared to loading system) Conveyor augers diameter min. 20 cm; drop-off route, rotary valve cross-section min. 600 cm

Consequence of overstepping particle size:

- Extra expenditures for correcting malfunctions

- Shortened service life of the conveyor augers and drives

5) Bulk density S (kg/m³), water content W (%), size G (mm) as per ÖNORM M 7133

In automatically loaded boiler plants, the wood fuels that come to be used should be individually listed in offers and

orders as follows: a) S 130 W10 to W20 G30/50 Sawdust, untreated (planing shop) b1) S 200 W20 to W35 G30/50 Sawdust, untreated (sawmill) b2) S 200 W20 G30/50 Forest wood chips, soft, untreated c1) S 250 W20 to W35 G30/50 Forest wood chips, soft, untreated c2) S 250 W35 to W50 G30/50 Sawdust, untreated (sawmill) d1) S 300 W20 to W35 G30/50 Forest wood chips, soft/hard, untreated d2) S 300 W35 to W50 G30/50 Forest wood chips, soft, untreated e1) S 350 W20 to W35 G30/50 Forest wood chips, hard, untreated e2) S 350 W35 to W50 G30/50 Forest wood chips, soft/hard, untreated e3) S 350 W50 to W60 G30/50 Forest wood chips, soft, untreated f1) S 400 W35 to W50 G30/50 Forest wood chips, hard, untreated f2) S 400 W50 to W60 G30/50 Forest wood chips, soft/hard, untreated g) S 130 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed h) S 200 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed i) S 250 less than W15 G30/50 Shavings & chips from wood remnants, dry, mixed j) S 350 less than W15 G30/50 Briquettes from wood remnants D 40 to 60 mm k1) S 650 less than W10 Pellets conforming to standards, untreated D 6 to 10 mm k2) S 650 less than W10 Pellets conforming to standards, untreated D 11 to 15 mm

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.

1) Liability on Orders of Confirmation, Altering and Cancelling Orders

1.1) If no other agreement exists, the confirmation of order determines the contents and the time of delivery. If the technical specifications of individual parts delivered are not restated in the confirmation of order, then the technical specifications stipulated in the last bid are valid.

1.2) Should in addition to the confirmation of order, the customer's order be valid, it is noted on the supplier's confirmation of order according to priority.

1.3) If within 10 days of sending the confirmation of order, no objection is raised, then the order is regarded as accepted. With terms of deliveries of less than 30 days, the window for objections is narrowed to 30% of the terms of delivery.

1.4) Altering and cancelling orders after the term of objection has expired, is only possible with the written consent of the supplier. Any additional cost is to the buyer's account.

2) Prices

2.1) The listed prices of the supplier (price lists) may be changed at any time without prior notice.

2.2) The listed prices of the supplier are ex-factory prices and do not include Value Added Taxes (VAT).

3) Illustrations, Properties and Technical Terms

All technical data, illustrations, measurements, diagrams and weights specified in bids, remain nonbinding until they are part of a binding documentation delivered in connection with an order of confirmation. All rights for construction related changes remain reserved. Materials may be replaced by equivalent alternatives.

4) Copyrights and Ownership of Technical Drawings and Documentations

Technical drawings and documentation that are handed to the buyer but do not form an integral part of the equipment and its applications, remain the property of the supplier. Only with the written consent of the supplier, may documents be passed on to third parties in a changed form or in the original form.

5) Copyrights and Ownership of Control Programs

Control programs used to control the equipment remain the property of the supplier. With the full payment of the equipment, the buyer receives life-long, unrestricted user rights to the control programs.

6) Terms of Delivery

6.1) Agreed upon terms of delivery are binding.

6.2) Equipment related preparations of the delivery site must be made before delivery of the equipment. Clarifications on the dimensions of the site (to adapt mountings and fittings of the equipment to the site, the following minimum terms of delivery are required:

14 days for feed worm up to D 150 mm

42 days for all other parts

Should it not be possible to make these preparations within the stated minimum terms and should the sup-

plier not be at fault, then the supplier is relieved of all liabilities of the term of delivery.

6.3) The supplier reserves the rights to hold back on the delivery should the agreed terms of payment not be met by the buyer.

6.4) Should any additional cost arise due to the delay in delivery, a mutually acceptable settlement of the cost to the buyer should be negotiated between the contract partners.

6.5) Should ordered equipment not be accepted at the agreed term of delivery, the supplier has the right to invoice the equipment to the buyer. Any additional cost arising from storage should be negotiated and settled between the contract partners

6.6) With on demand orders, the supplier reserves the right to only start with the production of the equipment after the receipt of the on demand order.

7) Shipment /Transportation

7.1) The supplier uses the type of packaging materials and means of transportation he deems suitable.

7.2) If no other agreement exists, the equipment is sold ex-factory. Furthermore, the INCOTERMS of the day of the contract signing is valid.

7.3) Should parts of the equipment be shipped individually at the buyer's request, then the additional cost will be to his account.

8) Installations by the Supplier

8.1) Has the mode of transportation and installation of the equipment been agreed upon, then the buyer is obligated to prepare the installation site on time and in the manner stipulated. These required preparations are listed in the confirmation of order under the position "Installation".

8.2) In general, a paved pathway suited for trucks that bring the equipment to the site must be prepared.

8.3) Furthermore, before installation starts, the masonry, carpentry and other preparatory work has to be moved along far enough so that upon delivery of the equipment, the installation technicians can take up their duties right away and carry them out without interruptions.

8.4) Should installation have to be interrupted due to lack of preparedness of masons, carpenters, etc. the buyer then must properly store the uninstalled equipment and protect it as if it was his own property

The cost arising from the delay and additional travel expenses of the installation technicians are to the buyer's account.

9) Inspection/Complaints during Handover

9.1) The buyer is obligated to inspect the goods immediately upon receipt.

Should the goods not correspond to the items on the delivery note, or in case of visible damage to the delivered goods, the buyer has to mark it on the delivery note. His failing to do so, validates the shipment of the items delivered.

9.2) A complaint outside of the terms voids the supplier's warranty.
