INFORMATION ABOUT YOUR HEATING SYSTEM
1. Information about your heating sys-
tem
Dear heating system owner,
With the purchase of this Hoval BioLyt (8-36) wood pel-
let boiler, you have made an excellent choice. It offers
you all the advantages of a modern and efcient heating
system.
Please read these instructions carefully. They describe
how the boiler works, how it is operated and serviced.
Further information can be obtained from our Sales and
Service Centres. (See last page for contact details).
1.1 Fuel quality / pellet delivery
1.1.1 Fuel quality
The BioLyt (8-36) wood pellet boiler has been designed
for optimum combustion of wood pellets. The pellets
must meet the requirements of at least one of the stand-
ards listed below
• ÖNORM M 7135
• DIN 51731 / HP5 (DINplus)
• SN 166000
• EN 14961-2 / A1 (ENplus/A1)
Hoval recommends ENplus (Class A1):
1.1.2 Pellet delivery
• Do not ll the storage room until after initial commis-
sioning of the boiler.
• Switch off the heating system as instructed 15 min. be-
fore lling the storage room.
• To measure pellet consumption since the last delivery,
reset the counter "USAGE 1." You can measure con-
sumption over a specic period of time (e.g. annual
consumption) by always resetting the counter on a spe-
cic date (e.g. January 1). For further information, see
Chapter 4.11.3.

IMPORTANT NOTES
(see Chapter 1.1); otherwise, any
possible warranty claims will become
any possible warranty claims).
2.3 Entering the pellet storage room, storage
tank
Under unfavourable circumstances, an increased con-
centration of harmful gases (such as carbon monoxide)
may occur in pellet storage rooms, possibly posing a risk
when accumulating over a longer period of time. Despite
the fact that under normal circumstances, there is no risk
at all, the possibility of such a scenario cannot be ruled
out.
• If work is being carried out in lled storage rooms, a
second person must always be present outside the
room for safety reasons.
• The pellet storage room must always be thoroughly
aerated before anyone enters it.
The storage room must be ventilated for at least 15
minutes. In the case of pellet storage rooms with a vol-
ume of more than 10 t, the duration of ventilation must
be extended or mechanical ventilation provided.
• No-one should enter the storage room in the four weeks
following lling. If it is necessary for persons to enter the
storage room, the room must be ventilated for at least 2
hours before entering.
• It must be ensured that the storage room door remains
open while there are persons inside the storage room.
• Entering fuel storage rooms that have not been aerated
(particularly underground tanks) must be avoided, and
only trained personnel is permitted to do so. Before en-
tering the room or tank, the concentration of CO must
be measured (the concentration must be less than 30
ppm). If necessary, thoroughly aerate the storage room
or tank before entering it.
• It the storage area is difcult to access or if it is acces-
sible only from above (as in the case of underground
tanks), the person entering the tank must be addition-
ally secured.
• Keep children away from the pellet storage area!

IMPORTANT NOTES
• If there are moving parts (worm conveyors) in the stor-
age room, turn off the mains switch of the heating sys-
tem before entering the storage room, as otherwise
there is a risk of injury.
• Smoking, naked ames and other possible sources of
ignition are prohibited inside the storage room.
2.4 Cautionary notes
(Information on the protection of the heating system)
Checking the water level
Check the water level in the system at regular intervals
(see Chapter 6).
Filling the heating system
The heating system can normally be lled and topped up
with mains water. No chemical additives should be added
to the water. The water quality can vary greatly in differ-
ent parts of the country (you can obtain information about
the water quality from your local water company), and it
might not always be suitable for lling the heating system
(highly corrosive or very hard water).
Please contact your heating engineer in such cases (see
also Technical Information).
Circulation pumps
During the periods when no heating is required, the circu-
lation pumps should be operated for approx. 2 minutes at
least once every month. This will prevent the pumps from
seizing up.
The doors and pellet hopper must be checked for leaks
on an annual basis. Smoke leaks should be avoided in
order to prevent any toxic low-temperature gases from
escaping into the boiler room.
Periodic cleaning and inspection by the heating engineer
or Hoval customer service will not only extend the ser-
vice life of the pellet boiler, but also increase its operat-
ing safety and ensure that a high combustion efciency
is maintained.
Pellet storage rooms must be cleaned regularly (approx.
every 2-3 years), and the sawdust which has accumu-
lated must be disposed of!
Protecting the boiler
Do not use sprays, solvents, chlorine-based cleaning
products, paint, adhesives etc. in the proximity of the
boiler. These substances can cause corrosion inside the
boiler and the ue gas system.
Periodically, a heating engineer must check the proper
functioning of the safety equipment (overpressure safety
valve, backre protection on the burner).
The heating installation must be inspected regularly ac-
cording to local regulations.

FUNCTIONAL PRINCIPLE OF THE HEATING SYSTEM
3. Functional principle of the heating system
It is important that the perfectly coordinated individual components function properly to ensure that your home stays
warm in winter.
Burns the pellets safely and in an environmentally friendly
manner..
Extracts the heat from the combustion gases and transfers
it to the heating water.
The process of combustion within the boiler converts the
natural energy contained in the pellets into heat.
Is used for intermediate storage of hot heating water
(max. 80°C). It thus compensates for any differences be-
tween heat generation and demand.
Holds a reserve of for household con-
sumption (e.g. for showering).
Controls and monitors the operation of the boiler. Main-
tains the desired room temperature optimally and fuel-ef-
ciently, independent of the outside temperature.
Releases the heat of the heating water into the room.
Transports the heating water from the boiler to the radia-
tors and back into the boiler, where it is reheated.
Transports the heat which is generated from the boiler to
the radiators.

3.1 What happens inside the BioLyt?
The BioLyt has been designed for the low-emission com-
bustion of wood pellets in accordance with ÖNORM M
7135 and DIN 51731, HP5 (/ DINplus) and EN 14961-2,
A1 / ENplus. The core element of the BioLyt is a rugged
horizontal burner tube, which provides a stable re bed
with its large, plate-shaped burner. The post-combustion
ring and dust separator above the burner plate give it a
distinct design. By combining these features, the burner
is able to keep dust emissions to a minimum. This is yet
another eco-friendly feature, since it burns with practically
no ash residues and provides for stable operation even
with variable pellet quality.
The BioLyt features a standard pellet hopper and an
optional fully-automated pellet feed system. When the
integrated pellet hopper is used exclusively, it needs to
be relled manually. When combined with the pellet feed
system, the pellet hopper is lled automatically from a
store. This feeder unit with control system and suction
turbine transports the pellets through a exible tube from
the storage room directly to the hopper. The hopper is
lled within minutes on a time-controlled and as-needed
basis, which is usually twice a day.

FUNCTIONAL PRINCIPLE OF THE HEATING SYSTEM
3.2 How does the automatic pellet feed (Option)
from the storage room work?
The pellets are extracted from the storage room either
directly via suction probes (Fig. 01), a mole system or by
means of a worm conveyor and then transported to the
pellet hopper on the boiler by means of a vacuum turbine.
The pellet hopper on the boiler includes two lling level
indicators:
• for the signal "pellet hopper full“ / top
• for the signal "pellet hopper empty“ / bottom on the
burner
The pellet hopper can only be lled during the preset en-
able time in order to minimise the noise in the building.
The lling process is started every time the burner enters
burn-out mode or, at the latest, when the bottom lling
level indicator signals “empty.”
First, the suction turbine starts up.
Then, the mole (if tted) or the discharge screw starts
operating after a delay of approx. 15 secs.
Discharge is stopped as soon as the upper lling level
indicator sends the signal for "pellet hopper full." If a mole
or a discharge screw are tted, the suction turbine runs
on for a time in order to ush the hoses.
The extraction system can be disabled during two peri-
ods of time per day (e.g. to avoid unwelcome noise dur-
ing the night). The factory settings are from 12.30 p.m. to
15.30 p.m. and from 22.00 p.m. to 07.00 a.m. To ensure
that there is an adequate supply of pellets to span such
off-periods, forced burn-out with lling of the pellet hop-
per is carried out 30 min. before the beginning of every
off-period. Off-periods can be deactivated by setting the
beginning and end of the respective period to 00.00 (see
Chapter 4.11.4).

HEATING SYSTEM CONTROL
4. Heating system control
4.1 What is the function of the boiler controller
TopTronic®T?
i
The boiler controller, together with the tem-
perature sensors connected to it, is, so to
speak, the brain of the heating system. Its
main functions are:
- maintaining the desired room temperature
independent of the outside temperature
- heating the living space only when required
- producing warm water (e.g. for showering)
only when required
- displaying information
further functions:
- input of desired temperatures and operat-
ing modes
- turning the heat generator ON/OFF
- monitoring temperatures
The correct settings for the heating system have already
been applied by Hoval, or the heating engineer, during
commissioning. Any changes to those settings should
only be carried out if you go away on a trip or if your
home is too cold or too warm. You can nd an overview of
the most frequently asked questions and the answers to
them in Chapter 4.4.3.
4.2 How you can save energy
i
use energy efciently and avoid unnecces-
sary losses:
With little effort, you can optimise the opera-
tion of your system and make it worth while.
to prevent your heating system generating
unnecessary heat when outside tempera-
tures are low in the morning and thus over-
heating your home. Turning the heating on
or off depending on the weather conditions
is one of the most effective energy-saving
measures. If you want to save yourself the
effort of going down into the cellar, you may
want to consider acquiring a “remote control”
from Hoval, which will allow you to operate
and control the heating comfortably from
your living room.
