2 Important information

2.1 Safety information
When carrying out work on the heating system,

such as cleaning and maintenance, wear ap­propriate protective equipping when required.
There is a danger of getting injured through:
burning, knocking against corners and edges,
crushing in moving parts and noise.

Mains supply: 230V

In a risky situation, the PYROMAT ECO can be
disconnected from the electrical mains at all the
leads by plug connector on the rear of the boiler
(1).

Doors

When the access door is not opened all the way, it
automatically falls back shut.

The burner must never be operated with the
doors open!

Any burning bits that escape could result in a fire.
Only open doors during the starting phase and the

burn-out phase (for refilling, exhaust gas tempera­ture less than 130°C). If the doors were opened
during operation, sparks and tongues of fire could
leap out.

Equipment for dissipating excess heat

The functioning of the thermal run-off safety valve
must be inspected every year by a competent spe­cialist.
The safety heat exchanger must not under any cir­cumstances be used as an operational heat ex­changer.

Seals

It is important for the functioning and controllability
of the burner that no unwanted air be able to enter
unchecked through leaks.
The doors and lids have to close tightly without
leakage. Any damaged seals must be immediately
replaced. Tighten snugly the fastening bolts and
handles.

Operation, cleaning & maintenance

Bear in mind that only if operated and maintained
properly can even the best of products fulfil their
functions well, for a long time and free of malfunc­tions.
Compliance with the "Cleaning" section is manda­tory!

2.2 Excess temperature & power failures

Do not open the doors or lids on the burner!

- Switch on additional heat consumers.

- The exhaust fan goes out of operation.

- The temperature-limiting safety switch triggers.

- The valve for the thermal run-off safety valve

opens at approx. 95°C. The excess heat is
conducted off into the channel.

If the temperature-limiting safety switch (TLSS)
has triggered, then it has to be manually unlo­cked.

To reset, unscrew the black cap and press the but­ton.
IMPORTANT

: Resetting is only possible at a boiler

temperature of less than 70° C.
Possible causes for excess temperature

:

- Incorrect setting on the control module.

- Defective component of the system (pump or

valve).

The TLSS (tempera­ture-limiting safety
switch) is situated in
the front metal plate
beneath the refill ac­cess lid.

2.3 Suitable and approved fuels

The KÖB PYROMAT ECO is designed for heating
chopped wood and wood waste and can be op­tionally equipped with an oil or gas burner.

Important prerequisites for the wood

The wood must be air-dry. One to two and a half
years are necessary for natural drying. This drying
can be carried out outdoors (covered) in part and
should then be continued for at least one year in a
suitable shed. The water content should amount to
a maximum of 25% (w 25).

Bear in mind:
Wood that has been stored for too short a time
and is still moist only has about half of its po­tential thermal power!

Types of wood

The KÖB PYROMAT ECO is especially well suited
for the types of wood listed below:

- Air-dry, chopped wood in its natural state, such
as split wood, billet wood and round wood.
Hardwood: max. ∅ 15 cm
Soft wood: max. ∅ 12 cm

Guideline figures for storage (for dry storage)
Hardwood: 2 to 2½ years
Soft wood: 1 to 1½ years

- Non-pelletised wood in its natural state (max.
water content of 25%) in the form of coarse
chips, woodchips, including bark adhering with
an edge length of Æ greater than 5 cm

- Compressed wood from chips, unless manufac­tured using bonding agent. Diameter Æ greater
than 4 cm

- Carpentry shop waste in the form of glued
wood and wood remnants, provided no wood
preservatives have been applied or are con­tained.
Edge length Æ greater than 5 cm

- Addition of a max. of 20% of brown coal bri­quettes to extend the combustion time.

Length of wood

Pyromat 35, 45, 55, 65, 75, 85 Æ max. ½ m
Pyromat 61, 81, 101, 151 Æ max. 1 m

Be sure to note:

The boiler is only suited for incinerating the wood
fuels and wood mixtures listed here.

If different fuels are used, KÖB will not assume
any liability for the functioning or service life of
the boiler.

It is not allowed to incinerate wastes or wood in
these heating systems that has been treated with
wood preservatives or the coating of which con­sists of halogenated organic compounds. In addi­tion to the development of highly toxic exhaust
gases, severe corrosion damage may also occur in
the boiler due to these chemical compounds (hy­drochloric acid).

The following must not be incinerated:

- Hard coal or coke

- Wood waste with coatings made of halo-

genated organic compounds (PVC)

Operation with an oil/gas burner:

Fuel: Extra-light heating oil

4 Starting up / Operation

4.1 Initial start-up

The initial start-up is carried out either by KÖB
Holzfeuerungen GmbH or another heating special­ist.

Be absolutely sure to follow the instructions in
the Assembly and Installation Instructions. No
guarantee may be claimed in cases of initial
start-ups carried out improperly by oneself.

First check:

- Is there enough water in the heating system?

- Has the heating system been bled?

- Are the slide valves open to the heating forward

and reverse flow?

- Can enough fresh air get into the heating

room?

- Are the doors and lids on the burner all closed

leak-tight?

4.2 Starting up

Check the storage unit temperature!

Check
whether the storage unit temperature has dropped
so far that heating up is practical, and whether the
amount of heat to be expected can be accepted or
stored.

Maximum storage unit temperature: 90°C

4.2.1 Filling
CAUTION: Never fill shavings or woodchips di-

rectly from the grate Æ There is a danger such
going up in flames suddenly!

- The slots in the grate have to be free of ash.

Only charcoal (approx. 2 cm) may remain lying
on the grate. Evenly spread out paper on this
(better than cardboard) and easily combustible
wood over the entire width of the burner
(approx. 25 cm high). Position the pieces of
wood crosswise such that a layer permeable to
air is created.

Finer material may only be filled on the layer of
chopped wood.

- Neatly lay the billet wood and logs horizontally

and compactly over the entire width of the fire­box.

- Only refill as much wood as energy that the

storage unit can still accommodate until the
maximum storage unit temperature of 90°C is
reached.

- When closing the access door, be sure that

the supporting surface for the refill access lid
seal is clean.

Note that even a small ember remaining can
also inadvertently ignite the kindling wood.

4.2.2 Heating up

Kindling

- Is the airway (1) to (3) clear through the entire
area of the grate, through fuel at the bottom and
into the combustion chamber? Is the lower part
of the wood loaded (2) permeable to air?

- Open the ash pan lid. Ignite, ideally doing so
over the entire width of the firebox,

- such that the fire spreads over the entire area
of the grate as quickly as possible.
Aim to keep the heating-up procedure short,
quickly producing a lot of heat and embers.
Rapid heating up of the combustion chamber
rapidly produces perfect incineration.

- Press the F1 button "PYROMAT Wood".

- Leave the ash pan lid approx. 10 cm open until
the material to be burned has started to burn
well.

- When the temperature of the exhaust gas
reaches approx. 110°C, close the ash pan lid.

4.2.3 Operation

- All the lids and doors have to be closed with no
leakage during the burn-off.

- The temperature of the exhaust gas should rise
to 130°C to 150°C in just a few minutes, and be
between 160°C and 200°C in continuous opera­tion.

- If the temperature of the exhaust gas prema­turely drops back down during the burn-off, you
have a hollow fire.
Cause:

Pieces of wood have been poorly
stacked or are irregular.
Remedy:

Carefully open the ash pan lid and
with a poker spread the wood over the entire
bed of embers.

Combustion time for:

- Each loading of wood from deciduous trees:
approx. 4 hours

- Each loading of wood from coniferous trees:
approx. 3 hours

4.2.4 Adding fuel

First check:

- Check the storage unit temperature! Can the

energy to be expected be accepted or stored?
Maximum storage unit temperature: 90°C.

- Is the burner already in the burn-out phase (ex-

haust gas temperature below 130°C)?

- Is the exhaust gas fan already out of operation?

Adding fuel:

- If the exhaust gas fan is already out of opera-

tion:
Press the F1 button "PYROMAT Wood".

- If the exhaust gas fan is still in operation:

Before adding

, press the F1 button "PYROMAT
Wood" (Add Fuel function). This will bring
about fast stabilisation of the operation.

- First only raise the access door slightly,

so that
any accumulation of low-temperature gas pre­sent in the upper part of the firebox can be suc­tioned off.

- Then unlock the safety lock (1) and open the lid
all the way.

- Neatly lay the billet wood and logs horizontally
and compactly over the entire width of the fire­box. Only refill as much wood as energy that
the storage unit can still accommodate.

I M P O R T A N T: Do not put any wood shav­ings or fine chips directly onto the embers Æ
There is a DANGER such GOING UP IN FLA­MES SUDDENLY!

- Close access door. Be sure that the supporting
surface for the refill access lid seal is clean.

Afterwards check:

- The surface of the ceramic combustion cham­ber should remain white.

- The vertical pipe-type heat exchanger must not
have any shining soot or tar deposits.

- The ash content is very low when the wood in­cinerates in a controlled fashion (approx. 1 per­cent by weight). The ash should be grey!

5 The ECOTRONIC Control System

5.1 General information

The ECOTRONIC facility control system is a de­centralised microprocessor system (CAN-BUS)
developed by KÖB with various modules that are
connected by a data transmission line.

Its function

The ECOTRONIC records all the data relevant to
operation and controls the supply of and demand
for heat.

Thus the burner system is continuously monitored
during all the operating phases and kept within an
optimum range in terms of emissions.

Factory settings (pre-settings)

All the parameters in the ECOTRONIC, including
set point values and switching times, are pre-set
and can be called back up at any time. The figures
for the factory settings are given in brackets for the
various parameters.

5.1.1 Battery replacement

There is a battery built in beneath the removable
lid on the control module (type: Panasonic Lithium
BR2330). It is for buffering the time, date and set­tings.

- The battery needs replacing every five

years!

- Do not disconnect the mains voltage while

changing the battery (do not turn off master

The heating curve

The correspondence of the flow temperature to the
outdoor temperature can be set directly and read
directly. The setting is carried out by two points:

Point 1:

Flow temperature at atmospheric temperature of
+5°C (setting range from 20°C to 90°C).

Point 2:

Flow temperature at atmospheric temperature of

-15°C (setting range from 20°C to 90°C).

I M P O R T A N T:
Point 2 always has to be higher than Point 1!

The two points marked indicate the factory setting.
Point 1 is set to 43°C and Point 2 to 64°C. This is
equivalent to a steepness of approx. 1.5.

Room thermostat (option):

The Model QAA 35 Room Thermostat can be used

with or without influence by the room tempera­ture.

Possible switch positions

:

- Position:
Heating operation following clocked programme
according to setting in the ECOTRONIC.

5.4.2 Utility water heater

Function:

- ECO-B1
When the temperature of the utility water drops,
it is reheated by the built-in heat exchanger
from the burner or from the heat accumulator.
The condition for this is a relevant difference in
temperature (choice of preset temperature dif­ference or fixed preset temperature).

The heating periods (daily and weekly pro­grammes) can be set using the integrated
timer.

- ECO-B2
When the temperature of the utility water drops,
it is reheated by the built-in heat exchanger
from the burner or from the heat accumulator.
The condition for this is a relevant difference in
temperature (choice of preset temperature dif­ference or fixed preset temperature).

The flow rate of the heating water is controlled
by the return temperature (quantity control).
This produces optimum storage stratification
with long-lasting high temperature on the stor­age unit flow pipe.

The heating periods (daily and weekly pro­grammes) can be set using the integrated
timer.

Operating modes:

- Off:

5.4.3 Air heater

Function (ECO-L):

The air heaters are supplied with maximum flow
temperature from the burner storage system. The
fans are connected by switches or controllers pro­vided by the customer. The flow rate of the heat­ing water is controlled by the temperature of the re­turn flow and thus adjusted to the air heater's
thermal output (quantity control). This produces
optimum storage stratification with long-lasting
high temperature on the storage unit flow pipe.

The heating periods (daily and weekly pro­grammes) can be set using the integrated timer.

Operating modes:

- Off:
The air heater is switched off

- Day / Off:
Heating operation following clocked
programme. During the day the system is
adjusted to the set point value for return flow,
and at night it is off.

5.4.4 Neighbouring buildings

Function (ECO-N):

The pipeline is usually supplied with a lowered
temperature required by the weather-guided heat­ing control system. The utility water heater is
loaded with the maximum flow temperature set.
To do so, the heating water is re-channelled by a
valve to the utility water heater. The integrated
timer shifts this to non-productive times, where the
room heating unit is quickly interrupted.

5.4.6 Additional boilers

Function:

- Boiler, single (ECO-KE)
To cover the heat requirement (single opera­tion), an additional boiler is automatically con­nected after the heat is removed from the stor­age unit. Loading of the storage unit is only
possible with the PYROMAT ECO. When it is
put into operation, the additional boiler switches
off, and the closed shut-off valve prevents it
from being flowed through.

- Boiler, single, gliding (ECO-KG)
To cover the heat requirement (single opera­tion), an additional boiler is automatically con­nected after the heat is removed from the stor­age unit. Loading of the storage unit is only
possible with the PYROMAT ECO. When it is
put into operation, the additional boiler switches
off, and the closed shut-off valve prevents it
from being flowed through. The boiler tempera­ture is adjusted in gliding fashion to the mini­mum temperature according to the heat re­quirement.

- Boiler, parallel (ECO-KP)
An additional boiler is automatically connected
when required. This may take place to cover
the heat requirement after the heat is removed
from the storage unit (single operation). Or the
additional boiler serves to cover peaks in heat
requirements (parallel operation to the PYRO-
MAT ECO). For parallel operation, a burner
group is necessary to carry off heat that simul­taneously provides for keeping up the return
flow.

Operating modes:

- Off:
The additional boiler is switched off.

- Automatic:
Automatic clearance of the additional boiler
through a request by a heat consumer, or (only
ECO-KP) when an adjustable connecting tem­perature for the wood-powered boiler is fallen
short of.

- On:
The additional boiler has been cleared.

- Manual:
The additional boiler has been cleared, and
(only ECO-KP) the pump is on; the valve is not
controlled (emergency operation).

5.4.7 Solar

Function (ECO-S1):

This is used in simple solar systems with a single
control circuit to heat the utility water in the solar
utility water heater (Art No: WSS- ...). The ECO­S1 controller is an additional component for the
ECO-B1(2) controller for the utility water heater.
When the solar collector is hotter than the utility
water at the bottom, it is heated up by the solar
collector.

Operating modes

- Off:
Pump off; valve shut

- Automatic:
Automatic heating of the solar utility water
heater by means of difference-based control.

- Manual:
Emergency operation: Pump on.

utility water heater at the bottom

(10) Operating hours counter
Function (ECO-S3):

This is used in large solar systems to heat the util­ity water in a solar utility water heater (Art. No:
WSS-...) and for supplying heat to the heat storage
tank by means of a triple control circuit. The first
circuit is for heating up the utility water, the second
circuit is for heating up the heat storage tank at the
rear/bottom, and the third circuit is for heating up
the heat storage tank in front/at the top. The heat­ing storage unit is heated up by an externally situ­ated plate-type heat exchanger. On switchover
from utility water heater to heating storage unit, the
secondary pump is switched on, which is then in
operation with the solar pump. For optimised func­tioning, the flow rate in the secondary circuit has to
be adapted to the primary circuit (e.g. with flow
rate gauges in the primary and secondary circuits).

Operating modes

- Off:
Pump off; valve shut

- Automatic:
Automatic heating of the solar utility water
heater by means of difference-based control.

(03) Priority to utility water (optimised)

- Optimised:

Priority to loading utility water, but if the solar out­put is not sufficient to finish loading the utility water
heater, there is a switchover to solar heated heat­ing. If the solar output rises (cyclical examination)
so much that heating of utility water is possible,
there is again a switchover to solar heated utility
water.

- Absolutely:

Loading utility water has absolute priority, i.e. solar
heated heating is not allowed until the utility water
heater has been completely loaded.

6 Cleaning

Regular cleaning of the facility is the customer's most important job for years of trouble-free opera­tion and to obtain the greatest possible output with the best efficiency.

The cleaning intervals may vary, depending on the fuel, the amount of fine matter and the operating
method.

CAUTION – RISK OF INJURY: Before beginning cleaning work, put the facility out of operation. Be
absolutely sure to wear protective gloves, protective eyewear if required and use the cleaning uten­sils that come with the facility – danger of blow-ups, burns and getting crushed!

Every two weeks:

Pull the exhaust turbulators out of the pipes
and dust or sweep them off. (Only with PY-
ROMAT ECO- 45, 65, 85, 81 and 151).
Then go through the bundle of tubes with the
cleaning brush that comes with the system.

Twice per year:

Unplug the plug from the exhaust gas fan,
unscrew the thumb screws, pull out the
motor with the running wheel and clean
with broom or wire brush. IMPORTANT:

DANGER OF GETTING INJURED!

Twice per year:

The fireclay-lined combustion chamber
has to be cleaned by a chimneysweep
using a vacuum cleaner from the front
through the opened ash pan lid.

Every day:

Open ash pan lid and with a poker move the fine ash through
slots in the grate into the ash pan.
If a lot of paper has been burned, completely remove the ash
from the grate.
If only wood has been burned, it is sufficient to evenly distribute
the charcoal.
When a lot of paper and cardboard are burned, the inlet into the
combustion chamber might also be clogged. If necessary, clear
with a poker.

Check ash pan and empty before it is completely full.

Twice per year:

Take off the panelling, undo the
thumb screws, take off the lid and
clean the combustion chamber
with a vacuum cleaner.

Weekly:
Unscrew win

g

nuts, take off lid and take out ash.

Monthly:

Take off lid and check the exhaust gas route for clear passage.

Every four weeks:

Open lid on the side (possible on both sides) and clean
the secondary air duct.

Every two weeks:

Open the lid on the side. Remove soot
and dust using the rear ash pan.

7 Shutdowns

Heating boiler

- Pipe-type heat exchanger
When the PYROMAT ECO is put out of opera­tion for a long period (such as for summer
breaks), be sure to carefully clean the pipe-type
heat exchanger with a steel brush required.

- Prevent high-temperature corrosion when
chipboards are incinerated:
If the heating room is moist or there is any other
atmosphere that promotes corrosion (e.g. poor
ventilation, residual enamel near the heating
room, etc.), after carrying out the cleaning, also
spray the pipe-type heat exchanger with bio­diesel.

- Remove encrustation from the walls of the
firebox and boiler with a trowel or flat scraper.

- If there is a danger of frost, empty the heating
system, following the heating installer's rules, or
have anti-frost agent filled.

Control system

Even when the PYROMAT ECO is put out of op­eration for long periods, the power supply to the
control system should not be interrupted (do not
turn off master switch).

Why

?

- The "intermittent control system" switches the
consumer pumps on for five seconds every 24
hours. This prevents the pumps from jamming
during long standstills. This saves on expen­sive repairs.

- Avoid the formation of condensation in the
lambda sensor.

- Extend the service life of the buffer battery.

8 Waste disposal

Shutting down operation

- Burn out the PYROMAT ECO and let it cool
down.

- Disconnect the mains connection to the control
cabinet.

IMPORTANT: DANGEROUS VOLTAGE!
Only licensed electrical firms are allowed to
disconnect and dismantle the connection to
the electrical network.

- Close the forward flow and return flow slide
valves.

- Open the drain tap on the bottom of the boiler
of the PYROMAT ECO and drain water.

Only heating system installers may drain the
boiler and dismantle the connections to the
heating system.

- Disconnect the forward flow pipe and return
flow pipe from the PYROMAT ECO.

Instructions regarding transport to a different
location

The personnel who carry out transports to different
locations have to know the dangers involved of ac­cidents that might arise in doing so and use suit­able measures to prevent such from happening.

Instructions regarding waste disposal

- Comply with customary laws and regulations on
disposing waste.

- Contract a disposal firm to dispose of and recy­cle waste in an environmentally friendly fashion.

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

2

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

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 th e 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.

9) Wood fuels: rules, regulations and standards
