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 ECO 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 auto­matically loaded combustion systems).

1.1 Technical standing

The operating instructions comply with the PYRO­MAT ECO at the time of its delivery. In the interest
of our customers, we reserve the right to make the

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 (the floor of which should
be fire-resistant) must always be provided for the
PYROMAT ECO solid fuel 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 re­quired for heating rooms that are small and/or in­ternally situated.
The temperature in the heating room must not ex­ceed +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 (in­terior side of the outside wall).

3.2 The chimney connection

PYROMAT ECO solid fuel boilers are equipped
with an exhaust gas fan and thus constitute a fire
site not requiring a draught.
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). An insulated 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 The water installations

Here we refer to the standards and regulations
cited in this document.

4.1 The safety equipment

The safety equipping for the heating installation
should be carried out by the installing heating en­gineer authorised to do so.

As examples, see spec sheets:
2960-1 Installation, Closed System
2960-2 Installation, Closed System
2960-3 Installation, Open System
2960-4 Installation, Open System

4.2 Expansion

The water volume enlarged by the storage units
(option) requires a correspondingly large expan­sion tank.
For closed expansion, the set pressure for the ex­pansion tank should be equal to the max. facility
height plus 0.2 bar.

4.3 The burner circuit with burner con-

trol valve and storage unit valve

To reliably prevent burner corrosion through con­densation of the exhaust gases, the burner tem­perature 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 2960-1 to 2960-4). 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.

3

5 The electrical installations

5.1 The positioning of the control mod-

ule and control system module

The installing electrical firm should mount the con­trol module at a place easily accessible for opera­tion. By positioning the control system module
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 influ­ences by heat radiation (rear side of burner with
exhaust gas collector and exhaust gas blower as
well as exhaust gas line) or interfere nce caused b y
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 out­side the heating room near the door to the heating
room.

5.2 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, ex­haust 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 equip­ment should be designed so as to be dustproof
and strain-relieved.

The regulations of the local electric supply
company must be complied with.

For the position and description of the motors and
sensors, see spec sheets.

6 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.

6.1 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.

7 Initial Start-up

The initial start-up of a newly installed facility may
only be carried out by KÖB & SCHÄFER GmbH or
another specialist cited and trained by it.
Before putting it into operation, the facility must be
filled with water as per 7.1, fuel must be put in as
per 7.2, and the installation has to be checked in
accordance with 7.3.

7.1 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 fill­ing is done. With difficult water conditions (high
degree of hardness, etc) and/or large water vol­umes, follow VDI Guideline 2035 "Preventing
Damage by Corrosion and Scaling in Hot Water
Heating Systems" by taking necessary measures
to treat the water.

Be very sure to note our General Terms and
Conditions of Delivery.

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

7.2 The fuel for the initial start-up

For starting up operation, dry fuel (max. w 20%)
must be put in amounting to at least two boiler fill­ings.

4

7.3 Inspecting the installation

Before the initial start-up, the future operating or­ganisation must inspect the installation with the in­stalling firm (installing heating engineer, electri­cian) 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 expansion tank is connected according to

instructions (see spec sheets).

7. The facility has been filled with water.

8. Combustible fuel has been provided in the

storage unit for the trial operation.

9. The control system is connected to the electric

mains.

10. The motors, switches and sensors are all con-

nected electrically.

Do not put the facility into operation over­hastily without the presence of a specialist
from KÖB & SCHÄFER GmbH or another spe­cialist cited and trained by it.
In case of damage you would lose your war­ranty claims.

Pyromat-ECO

Note:

- To reliably prevent burner corrosion caused by condensation of exhaust gases, the burner return flow temperature
must not by any means be below 65°C. To do so, a burner circuit pump should be provided with a burner control
valve as per the diagram. The burner circuit should be configured such that the temperature difference between the
forward and return flow is equal to or less than 15°C.

This is the case in the design below if no additional resistors are installed in the burner/accumulator circuit. Any
installation of slide valves or of a heat meter in the burner/accumulator circuit will require reconfiguration of the burner
pump and burner control valve by the heating technician.

- For incorporation of heat consumers or additional heat generators, refer to Spec Sheets 4000ff.

- The expansion tank has to be connected to the burner via the burner inlet without any blockage units.
