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.

5

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.

6

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.

To reliably prevent boiler corrosion caused by condensation of exhaust gases, the boiler return flow temperature must

not under any circumstances be below 65°C. A boiler circuit pump with a boiler mixer should be provided according

to the diagram for this purpose. The boiler circuit should be designed such that the temperature difference between

the forward flow and the return flow is equal to or less than 15°C.

For integrating heat consumers, see Spec Sheet 4000.

b) Safety-relevant equipment included in the scope of performance provided by the installing
heating engineer

M 20 Boiler pump
Y 20 Boiler mixer
TS131 Thermal run-off safety valve R ¾”, homologated component; special-purpose design for opening

temperature 100°C, (safety heat exchanger built into boiler). With the Pyrot-400 and Pyrot-540, two safety

heat exchangers in parallel are required but only one thermal run-off safety valve.
These are not required for open systems, but we advise installing these.
KW Cold water inlet, min. 2.5 bar, max. 3.5 bar
WMS Water level control device, homologated component; required in Germany starting from systems over 350

kW,Installation recommendation: WMS with magnetic transmission of the float movement to a switch unit

Be sure to note:

• The lines must be executed in metal (1/2") with fixed pipework (K-SLE and K-SLV).

• It must not be possible to shut off the cold water inlet without the aid of tools.

• Be especially sure to comply with Point 5 of the Installation Instructions (Fire Prevention).

Note:
K-SLV is an alternative or supplementary safety device. As standard, either a slide valve (Art. No. MBA-.; included in
Article ADF_.,. / ADE_3,0) is required for pressureless material storage sites or a rotary valve (Art. No. MBZ-.) for
material storage sites with over- or under-pressure (loading with fan, such as wood-processing businesses).
