1 General information
Only specialists may set up and put into operation
Köb solid fuel burners. This will rule out any faulty
installation or initial start-up. These instructions
are therefore limited to important technical data,
references to ordinances, technical rules and other
regulations.
The PYROMAT DYN is a Burner Class 3 boiler for
heating systems with hot water with a protection
temperature of 110° C as per EN 303-5: 1999
(heating boilers for solid fuels, manual and auto-
matically loaded combustion systems).

3 The structural surroundings of
the burner
Existing national building ordinances in this
connection must always be complied with.
3.1 Heating room requirements
A separate heating room must always be provided
for PYROMAT DYN wood heating systems. The
heating boiler may only be set up on a fire-
resistant floor. No temperature-sensitive pipes or
lines may be installed in the floor beneath the heat-
ing boiler.
The minimum distances to the walls and the ceiling
required according to the table of dimensions for
proper cleaning and maintenance of the boiler
have to be complied with. A sufficient supply of
fresh air has to be provided directly from outdoors
into the heating room. Induced ventilation is re-
quired for heating rooms that are small and/or in-
ternally situated.
The temperature in the heating room must not ex-
ceed +40° C while the system is in operation
(boiler surroundings 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 (in-
terior side of the outside wall).
3.2 The chimney connection
The PYROMAT DYN is equipped with an exhaust
blower and so it is a fireplace not requiring a draft.
The design of the chimney should be carried out
as for a fireplace with an oil or gas blast burner not
requiring a draft (temperature of exhaust gas at
nominal load: 160°-200° C).
The PYROMAT DYN is output-controlled within a
range of 30%-100% of the nominal burner output.
This results in exhaust gas temperatures within a
range of min. 100° C and max. 250° C. An insu-
lated chimney should be provided to prevent the
danger of sooting.
The path from the exhaust blower to the chimney
should be as short as possible. 90° bends should
be avoided if possible. Exhaust gas lines with
lengths longer than 1 m should be insulated.
The connection to the chimney should be carried
out in a fashion rising at an angle of 30°-45°. The
exhaust gas line, incl. the lead-in into the chimney
should be designed so as to be gas-tight.
4 Transport and installation
The transport lug (1) is in the ash pan on delivery
and for transport purposes can be screwed in at
the top of the burner in place of the inspection win-
dow.
After moving it into the heating room, screw off the
transport feet (2) and position the burner such that
it is level.
The handle (incl. the safety lock for the refill ac-
cess cover) is in the ash pan on delivery.

5 The water installations
Here we refer to the standards and regulations
cited in this document.
5.1 The safety equipment
The safety equipping for the heating installation
should be carried out by the installing heating en-
gineer authorised to do so.
See Spec Sheets 3950-x for examples
5.2 Expansion
The water volume enlarged by the storage units
(option) requires a correspondingly large expan-
sion tank.
For closed expansion, the set pressure for the ex-
pansion tank should be equal to the max. facility
height plus 0.2 bar.
5.3 The burner circuit with burner con-
trol valve and storage unit valve
To reliably prevent burner corrosion through con-
densation of the exhaust gases, the burner tem-
perature must in no case be less than 70° C. For
this, a burner circuit pump should be provided with
a boiler control valve according to the diagram
(Spec Sheets 3950-x). The design of the burner
circuit should be carried out in such fashion that
the temperature difference between forward flow
and reverse flow is equal to or less than 15° C.
The triggering of the burner pump (230 V), burner
control valve and storage unit valve is integrated in
the control system that comes with the equipment.
5.4 Container for extinguishing water
(option)
Take note of the information on data sheet 4500.
As far as the installation is concerned, refer to the
installation instructions for the feed auger.
This functions by means of an extinguishing valve
and is not dependent on electric current. A float-
type level-control switch monitors the water level
and connects electrically. (See terminal connec-
tion diagram).

6 The electrical installations
6.1 The positioning of the control mod-
ule and control system module (option)
The installing electrical firm should mount the con-
trol module at a place easily accessible for opera-
tion. By positioning the control system module
(option) near the heating distributor, the lengths of
the lines can be minimised, thus reducing costs.
The position for the control system components
has to be selected such that any negative influ-
ences by heat radiation (rear side of burner with
exhaust gas collector and exhaust gas blower as
well as exhaust gas line) or interference caused by
dust during cleaning are as little as possible.
The ambient temperature (approx. 10 cm away) for
the control system components during operation of
the facility must not exceed 35° C. If there is any
doubt, place the control system components out-
side the heating room near the door to the heating
room.
6.2 Electrical connection
- Connect it according to the wiring plan, laying of
the CAN-BUS wire according to data sheet
4020.
- Around hot elements (exhaust gas blower, ex-
haust gas pipe), the lines should be installed so
as to be temperature-protected in steel pipes at
the distance necessary.
- The cable bushings to the motors and equip-
ment should be designed so as to be dustproof
and strain-relieved.
The regulations of the local electric supply
company must be complied with.
7 Fire protection
The fire protection regulations for wood heating
systems vary for each specific country.
The regulations valid for the respective place of
installation must be complied with.
7.1 Protection for the burner system
against back-burn
7.1.1 Preventing overfilling of the combustion
chamber
According to TRVB 118, a level monitor must be
installed to prevent any overfilling of the combus-
tion chamber. The PYROMAT DYN has a light
barrier as an ember monitoring system.
7.1.2 Preventing back-burn
With a sensor directly on the insertion pipe, any in-
cipient danger of back-burn will be detected and
counter-acted early on by an increase in the output
for a short period (increase in the advancing of ma-
terial). As a result, any protective equipment being
prescribed is prevented from going into force, and
normal operation is maintained for the purpose of
reliably providing the greatest possible supply of
heat.
7.1.3 The back-flash safeguard
According to TRVB 118, a back-flash safeguard is
prescribed for all systems over 150 kW.
TRD 414 prescribes a continuously present isolat-
ing layer if one foregoes having a spark alarm and
extinguishing system (TRD 414 relates primarily to
remnant wood from the processing of wood and
derived timber products). There is easing of re-
strictions in part in this connection for chip materi-
als from forestry and sawing activities. The PY-
ROMAT DYN 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 PYROMAT DYN is considered as
equipped with a back-flash safeguard.

7
7.1.4 Automatically Triggering Extinguishing
System for the Burner Auger = ATEBA
A water extinguishing system on the feed auger is
available as an option.
This device is used to reliably prevent any back
burn in case of a malfunction (such as a power
failure). For safety reasons and to prevent any
damage caused by overflowing, connecting this
extinguishing device directly to the water supply
network is not advised.
This extinguishing device is always equipped with
a 25-litre container for extinguishing water with a
float-type level-control switch and an adjustable
Danfos extinguishing valve.
According to TRVB 118, the container for the
automatically triggering extinguishing device must
be equipped with a level monitoring system.
If there is a shortage of water, the PYROMAT DYN
will switch off automatically. In case of excess
temperature, the feed auger will be flooded reliably
but to a limited degree.
The installing heating engineer should carry
out the pipework for the automatically trigger-
ing extinguishing system for the burner auger
in accordance with Spec Sheet 4550.
7.2 Back-burn safeguard for the fuel
supply system
The further "back-burn safeguard for material
transport" depends on the respective requirements
(position and size of the fuel storage unit, material,
pressure conditions and regulations), these being
separate items of the scope of delivery ordered
with Köb Holzheizsysteme GmbH according to the
following descriptions.
7.2.1 Automatically Triggering System for the
Material Supply System (ATSMS)
Approved in part as a variation to the slide valve in
non-pressurised fuel storage units (does not meet
TRVB).
The installation of the Automatically Triggering
System for the Material Supply System
(ATSMS) should be carried out by the installing
heating engineer according to Spec Sheet
4550.
7.2.2 Slide valve, type MBA
This is approved in non-pressurised fuel storage
units for all cases and according to TRVB 118 (test
certificate BV 2979/89) is considered as a suitable
back-burn safeguarding device.
7.2.3 Rotary valve, type MBS
If the remnant wood is put into the fuel storage
space with blowers, then due to the pressurisation,
at least one rotary valve is required between the
fuel storage unit and the burner to reduce the
pressure. A rotary valve is suited for reducing the
pressure and according to TRVB 118 (test certifi-
cate BV 2979/89) is also considered as a suitable
back-burn safeguarding device.
Max. permissible excess pressure in the fuel
storage unit: + 500 Pa
Max. permissible negative pressure in the fuel
storage unit: + 0 Pa
7.2.4 Double rotary valve with pressure com-
pensation
If, due to special circumstances, any mechanically
induced negative pressures or extraordinarily high
excess pressures are to be expected in the fuel
storage unit, then two rotary valves with a pressure
compensation line leading outdoors should be built
into the material transport route according to the
respective project plan.
Max. permissible excess pressure in the fuel
storage unit: + 3000 Pa
Max. permissible negative pressure in the fuel
storage unit: - 3000 Pa
You should have the maximum pressures to be
expected confirmed by the supplier of the chip
suctioning system.
The rotary valve beneath the silo extraction system
may become leaky due to wearing of the sealing
elements or due to large pieces of wood not able
to be conveyed. Any such leakiness may make it
possible for low-temperature gases to flow back
from the firing furnace into the silo.
A smoke gas alarm should be installed between
the revolving valve and the silo extraction system,
which when triggered will disconnect the system
causing the negative silo pressure.
7.3 Fire protection for the fuel storage
unit
The measures necessary for this are never a part
of the Köb Holzheizsysteme GmbH scope of deliv-
ery.
In this regard, the conditions set by the local
building authority must be met by the operating
organisation.

8
8 Initial Start-up
The first start-up of operation for a newly installed
facility may only be carried out by Köb Holz-
heizsysteme GmbH or another trained specialist.
Before the initial start-up, fill the facility with water,
provide fuel in the storage unit for the initial start-
up and inspect the installation.
8.1 Filling the heating system
The first filling is usually done with untreated water
without any chemical water treatment but definitely
filtered and thus free of any suspended matter.
Be sure to carefully bleed out any air when the fill-
ing is done. With difficult water conditions (high
degree of hardness, etc) and/or large water vol-
umes, follow VDI Guideline 2035 "Preventing
Damage by Corrosion and Scaling in Hot Water
Heating Systems" by taking necessary measures
to treat the water.
Note: The filling pressure of the cold water re-
serve should be approx. 0.1 bar times greater
than the set pressure of the closed expansion
container.
8.2 The fuel for the initial start-up
A sufficient quantity of dry fuel (max of w 20%)
should be stored.
- Approx. ten full hours of operation for auto-
matic operation.
- Approx. two burner fillings for manually loaded
operation.
8.3 Inspecting the installation
Before the initial start-up, the future operating or-
ganisation must inspect the installation with the in-
stalling firm (installing heating engineer, electri-
cian) for the following points:
1. Exhaust gas connection piece connected to
the exhaust gas line to the chimney.
2. Chimney completely installed with clear cross-
sectional area all the way through.
3. Safety valve mounted on burner and/or burner
inlet.
4. Thermal run-off safety valve connected to the
cold water mains.
5. The sensor for the thermal run-off safety valve
is in the dipping shell.
6. The container for extinguishing water (option)
on the feed auger is filled with water.
7. The sensor for the extinguishing valve (option)
is firmly mounted on the pipe for the feed au-
ger.
8. The expansion contained is connected.
9. The conveyor devices between the burner and
material storage unit are installed.
10. The facility has been filled with water.
11. Combustible fuel has been provided in the
storage unit for the trial operation.
12. The safety end switch has been installed on
the door to the material storage place (if there
is a door that can be walked through).
13. The control system is connected to the electric
mains.
14. The motors, switches and sensors are all con-
nected electrically.
Do not put the facility into operation too soon
without the presence of a specialist from Köb
Holzheizsysteme GmbH or another trained spe-
cialist.
In case of damage, you would lose your war-
ranty claims.

Description:
The PYROMAT-DYN is a boiler with patented double combustion chamber. Which means that the burner system enables
optimized operation with automatic loading (shavings, chippings from waste wood, wood chippings, max. W35; G50) and
may also be used with logs. A large loading shaft with loading lid and separate grid has been fitted in front of the main
combustion chamber to make loading wood easy. In automatic operation, the burner system is suitable for all dry to moist
wood fuels (max. W35). The control is integrated into the burner system with connector-ready cabling to the sensors and
motors. Which permits simple and rapid installation. The PYROMAT-DYN 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: 3.0 bar
Electric connection: 3 x 400V
Safety heat exchanger: Built into the boiler
Function:
- In manual operation, chopped wood and waste wood are degassed on the incineration grate situated before the
main combustion chamber. Simultaneous operation with automatic loading is not possible.
- In automatic operation the feed auger conveys the material to be burned into the main combustion chamber for
degasification.
The fasteners for the burn-back sensor and the thermally operated extinguisher 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.
- In automatic operation the material to be incinerated is ignited automatically by an electric hot air blower.
The combustion gases are entirely burned out in the afterburn chamber together with secondary airflow.
- The ash is mechanically removed from the main combustion chamber.
- In the upright pipe heat exchanger, the thermal energy from the combustion gases is transferred to
the boiler water. The vertical surfaces of the heat exchanger are regularly cleaned by motor-driven,
moving coil springs.
- The speed-controlled exhaust blower was specially designed for operation in wood heating systems and is very quiet.
- The negative pressure created by it produces a high degree of safety against burn-back in automatic operation and a
convenient feed function in manual operation.
- An integrated heat management system (accumulator-temperature-guided with return circuit valve) enables the best
possible controlled operation.
Scope of delivery:
-Boiler with double combustion chamber, ash pan, kindling and cleaning utensils, coil springs for the heat exchanger
cleaning system, mechanical drive with position sensor for removing the ash from the main combustion chamber.
- Exhaust blower, plug-and-play
- Integrated ECOTRONIC control system (decentralised microprocessor system via CAN-bus), consisting of:
Boiler control panel, control module for mounting preferably on a wall, bus cable for the drive motors wired to
output plug
- Feed auger with isolating layer, incl. Starttec drive via CAN-bus (including data transmission line) for gentle start-up,
automatic reversing and overload safeguard, light barriers for combustion chamber and metering container
-Automatic ignition system
- Burner group ready-installed on connecting flange, consisting of burner pump, two blockage units
Burner control valve, forward and return flow sensors incl. fittings.
-Three KTY heat accumulator sensors, incl. dipping shell (1/2" x 280 mm long) wired together to plug
-Four-pin master switch, uninstalled (for installation near the control module)
