2.2 Excess temperature/power failure
2 Important Information
2.1 Safety instructions
CAUTION
DANGER OF THIS SUDDENLY GOING UP IN
FLAMES:
Do not open the doors or lids on the boiler
plant!
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: 400V C
In a risky situation, the PYROT can be disconnected from the electrical mains at all the leads by
the master switch on the control cabinet
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. The TLSS is situated at the top
of the boiler.
Doors
CAUTION
FIRE HAZARD:
The boiler plant must never be operated with
the doors open! Red-hot objects that might
escape could result in fires.
To reset, unscrew the black cap and press the
button.
NOTE: Only as of a temperature of approx. 70°C
resetting is possible.
Possible causes for excess temperature:
- Incorrect setting on the control module.
- Defective component of the system (pump or
valve).
- Sudden drop in output to zero. The feed auger
still has to be emptied. The heat yet produced
by this can result in surplus temperature. Activate "DISSIPATE SURPLUS HEAT" function!
RISK OF INJURY:
If the doors are open during operation, sparks
or flames could leap out.
Equipment for dissipating excess heat
The operational reliability of the thermal run-off
safety valve should be examined annually by a
competent specialist. The safety heat exchanger
must not by any means be used as an operational
heat exchanger.
2.3 Low water/excess water pressure
Possible causes:
1. Low water: Leakage in the heating system.
2. Excess water pressure: The expansion system
not functioning.
Seals
In either case, one should have the facility examined by a competent heating installer.
For the functioning and controllability of the
burner, it is important that no unwanted air can
leak in, entering unchecked through leaky spots.
The doors and lids have to shut tight − any damaged seals must be replaced immediately.
Tighten the retaining screws and handles snugly.
Unlock this malfunction with either the reset
button for the water level control system or for
the overpressure monitor, and by pressing the
OK key on the control panel.
Operation, cleaning & maintenance
Bear in mind that only if operated and maintained
properly can even the best of products fulfil their
functions well, doing so for a long time and free of
malfunctions.
Compliance with the "Cleaning" section is mandatory!
5
2.4 A fire hazard
With insertion-type firing systems, the conveying
route creates a connection between the silo and
the burning material in the boiler plant.
With the PYROT insertion-type heating boiler, the
feed auger is also the metering auger, and is thus
always filled up with material during operation
There are various safety devices provided to prevent burn-back.
Heating out of operation:
- If the articulated arms or spring-mounted
plates are still covered by fuel, refilling can be
carried out immediately.
- If the articulated arms or spring-mounted
plates are no longer covered by fuel, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. Then
activate the "SILO FILLING" function. To do
so, press the LOADER SYSTEM key (F4) and
then the left arrow key (<). Then select "YES"
and confirm with "OK". Wait until the articulated arms or the spring-mounted blades go
under the cup washer, and then finish evenly
filling the silo. The "SILO FILLING" function
brings about the filling of the fire box.
Temperature sensors:
By means of temperature sensors on the feed auger, in case of excess temperature the loading to
the feed auger is interrupted, and the feed auger's
material is inserted into the combustion chamber.
Slide valve (optional):
This closes in case of a standstill, danger of burnback or power failure (spring return motor).
NOTE: The "SILO FILLING" function cannot be
activated until the heating system has been
out of operation for one hour.
Rotary valve (optional):
Instead of a slide valve, in silos with pressurisation.
Drop-off route:
A vertical drop-off section interrupts the connected line of burning material.
Moving floor conveyor
Fire-extinguishing system (option):
This system, which functions independently of the
electrical power, brings about a flooding of the
material to be burned that is located in the feed
auger. The activation temperature is approx.
95°C.
Funnel extraction system
-
-
Fuel can be refilled automatically.
It is mandatory that the heating system be in
operation!
2.6.2 By blowing in
The heating system has to be out of operation
(danger of excess pressure or negative pressure caused by the action of blowing-in). Filling procedure as described in section 2.6.1.
2.5 Wood fuels, minimum requirements
The PYROT is only suitable for incinerating the
fuels listed in Spec Sheet 1010 "Minimum Requirements for Wood Fuels" (see supplement).
2.7 Correcting malfunctions in the feed systems
The cause of motor malfunctions in feed systems
is usually clogging by large pieces of wood or foreign matter.
If different fuels are used, KÖB will not assume any liability for the functioning or service life of the boiler plant. Refer to the "Warranty" section in the General Terms and Conditions of Delivery.
2.6 Filling the fuel storage unit
CAUTION
DANGER OF INJURY:
Always turn off the master switch before carrying out any repair of a malfunction on feed
systems and every time before a maintenance
lid is opened or a protective device is removed!
2.6.1 By dumping
Rotary sweep extraction and spring-operated
extraction
Heating system in operation:
- If the articulated arms or spring-mounted
plates are still covered by fuel, refilling can be
carried out immediately.
- If the articulated arms or spring-mounted
plates are no longer covered by fuel, fill the silo
evenly to approx. 30 cm above the articulated
arm or over the spring-mounted plates. As
soon as the articulated arms or springmounted plates have retracted through a request for material, the refilling can be continued.
The automatic operation of the system makes it
impossible to foresee the time point when the
conveying equipment will switch on.

4 Commissioning/Operation
4.1 The initial start-up
The initial start-up is carried out either by KÖB
Holzfeuerungen GmbH or a competent individual
named by it.
-
When the "System Temperature Setting" is
fallen short of, the facility is automatically started back up.
4.2.3 Switching off
Be absolutely sure to follow the instructions in
the Assembly and Installation Instructions. No
guarantee may be claimed for damages in
cases of initial start-ups carried out improperly at one's own initiative.
-
CAUTION: Do NOT use the master button to
switch off (DANGER OF BACK BURN) !!!
First check:
-
Is there enough water in the heating system?
Has the heating system been bled of air?
Are the slide valves open for the heatingsystem's forward and reverse flow?
Can enough fresh air get into the heating
room?
Empty ash bin.
Are the doors and lids on the burner all closed
leak-tight?
4.2 Operation
4.2.1 Heating up
-
-
Press the F1 key "PYROT Wood". The loader
modules will be switched on in the appropriate
order. When there is enough fuel in the combustion chamber, the entire loader system
switches off.
The automatic ignition then takes place. The
ignition process stops as soon as the fire is
started.
4.2.2 Operation
-
-
-
-
Press the F1 key "PYROT Wood". As feedback to this, "Run Auger Empty" will appear on
the control panel.
The material is supplied depending on the light
barriers in the metering container and in the
combustion chamber, allowing for the residual
oxygen.
The primary and secondary air vents change
their positions depending on the exhaust gas
temperature and residual oxygen.
Using the setting "Storage Management, Temperature, Storage, Average", it is possible to
keep the facility in continuous highperformance operation for as long as possible
– with fewer ignitions, better efficiency and lower emissions.
(Only possible with accumulator option)
When the boiler temperature set is reached,
the facility switches to "Run Auger Empty".
When the feed auger has been run empty, and
the exhaust gas temperature is less than 90°C,
the exhaust gas fan switches off and the air
vents close.

5 Oil burners on a Pyrot
Be sure to note:
-
-
-
The oil burner's firing power may amount to a
maximum of 70% of the rated heat output in
wood-burning operation.
The selection of the oil burner as well as the
actual nozzle length have to be determined by
the supplier of the oil burner.
Only either wood-burning operation or oilburning operation is possible.
For wood-burning operation, put in the sealing
plug.
Close the flue gas recirculation system.
Set the speed of the exhaust fan such that the
flame only reaches halfway up the fireclaylined flame tube.

Function (ECO-S3):
(Only possible with accumulator option)
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 accumulator by means of a triple control circuit. The
first circuit is for heating the domestic water, the
second circuit is for heating the heat accumulator
at the back/bottom and the third circuit is for heating the heat accumulator at the front/top. The
heating storage unit is heated up by an externally
situated plate-type heat exchanger. On switchover
from utility water heater to heat accumulator, 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).

7 Cleaning/Maintenance
7.1 Boiler
Regular cleaning and maintenance 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.
Here the cleaning intervals for chip material are listed as per ÖNORM M 7133 with clinging bark –
0.8% ash content. 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)!
After approx. 1000 operating hours:
Unplug the plug from the exhaust gas
fan, unscrew butterfly nuts, pull out motor with impeller and clean with broom or
wire brush.
CAUTION: DANGER OF INJURY – be
absolutely sure to switch off master
switch.
With pneumatic pipe cleaning system, after
approx. 600 operating hours; without pneumatic
pipe cleaning system, after approx. 300 operating hours:
Open boiler door and clean all the heat exchanger
pipes (9) with wire cleaning brush. Use the stoker
to carefully draw to the front the fly ash lying in the
rotation combustion chamber (8).
IMPORTANT:
With pneumatic pipe-cleaning system, disconnect the compressed air line before opening the
boiler door – danger of injury!

After approx. 300 operating hours:
Take off and clean light
barriers and inspection
windows on the firing
block.
Remove dust and ash deposits in the openings.
After approx. 1000 operating hours:
Clean recirculated flue
gas line.
After approx. 100 operating hours:
Open ash pan doors and empty ash containers.
With automatic de-ashing (optional),
cleaning interval of approx. 1000 operating hours.
After approx. 300 operating hours:
Remove ash from the exhaust gas collector.
21
Pneumatic tube-cleaning system (optional)
Exhaust gas deduster, detached (optional)
After approx. 1000 operating hours:
Unplug the plug, unscrew butterfly nuts, pull
out motor with impeller and clean with broom
or wire brush.
CAUTION: DANGER OF INJURY – be absolutely sure to switch off master switch.
After each cleaning of the set of tubing
Open lid and clean the guide blades of
the de-duster with hand-brush.
Regularly drain condensation water in the
compressed air distribution bar.
After approx. 300 operating hours (90litre ash bin):
Empty ash bin beneath the de-duster.
IMPORTANT: Never operate the boiler without
ash container!
22
-
Operation and maintenance of the compressor
(optional) according to the manual that comes
with the facility.
-
The timer that comes with the compressor is for
limiting the running time and should be
mounted between the compressor and the
power supply.
-
When the compressed air system is provided
by the customer, the compressor has to be
suited for continuous operation or be secured
against continuous operation (e.g. timer for limiting running time).
-
Continuous operation of the compressor indicates leakage in the air system. Check air supply line and valves for leakage.
7.1 Installing the displacement rods into the
heat exchanger
The displacement rods improve the heat transmission in the heat exchanger and reduce the temperature of the exhaust gas, thus improving the efficiency of the heating system. They are taken out
to clean the heat exchanger tubes and then put
back in.
Insert the displacement rods into the heat exchanger tube with the thick end first. Push until
they are flush with the bottom of the tube. Tolerance +/- 5 mm.
Fig. 1
Flush with
the bottoms
of the tubes
Remove the displacement rods with a pair of pliers, as shown below. The heat exchanger should
be cleaned at the intervals prescribed so that, on
the one hand, performance and efficiency are
maintained, and on the other, the displacement
rods can be easily removed.
Fig. 2
23
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.
- Prevent the formation of condensation in the
lambda sensor.
- Extend the service life of the buffer battery.
7.2 Feed systems
All the geared motors on the feed systems are
maintenance-free.
-
-
-
-
A change of lubricant and/or oil is recommended every 20,000 operating hours or every
three years.
Re-lubricate flange bearings and other lubricating points regularly with lithium soap grease.
Check chain drives for wear and, if necessary,
tighten them up and lubricate with chain oil.
Check all the bolts to be sure they are snug.
Once a year check the extraction components
in the silo and/or bunker for damage and soiling. Remove any foreign matter there might be.
Rotary sweep extraction system (AG)
Check and lubricate elbow joints, pivot pins,
tension springs and tension chains. Readjust
elbow joints if necessary.
Inclined extraction system (AP/APS)
Lubricate the gasket between the extraction casing and the geared motor and universal joint
for the auger.

Pipe-type heat exchanger:
When the PYROT 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.
Only heating system installers may drain the
boiler and dismantle the connections to the
heating system.
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.
-
Disconnect the forward flow pipe and return
flow pipe from the PYROT.
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.
If there is a danger of frost, empty the heating
system, following the heating installer's rules, or
have anti-frost agent filled.

2007-09-12_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 (K2O 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

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.
