Biopel MINI - Installation and Operation Instructions

Vsp ….. storage tank volume in l
Tb ...…. burning time in h
Qn …… nominal thermal power in kW
QH …… building thermal load in kW
Qmin … minimum thermal power in kW
The storage tank dimensions must be determined according to the boiler power. The pellet boiler does not require
a storage tank for its operation. There is no excess heat to be stored in the storage tank. On the contrary, the boiler
modulates its power so that it never exceeds the set limit. If the boiler heats the heating system to the desired level,
it switches off and on again when the temperature drops.
A storage tank is recommended if the heating system contains more than one heating branch and generally for
more complex heating systems with several heating circuits. We recommend that you consult a professional
plumbing company or representatives of OPOP spol. s.r.o. before purchasing a storage tank.

REGULAR MAINTENANCE
Boiler maintenance is an integral part of solid fuel boiler operation. Recommended intervals for manual cleaning of
the boiler, burner and flue. Please note that the intervals given are only basic recommendations and may differ
from the actual requirement for regular cleaning. The frequency of regular cleaning is generally determined by the
quality of the combustion process, pellet type and quality, dust level and moisture in pellets, chimney draft, etc.
Therefore, always check the clogging rate of the boiler at short intervals during the first months of operation so
that you can determine how often the boiler, burner and flue gas outlet need to be cleaned according to the actual
situation.

a)
Cleaning the ashtray is an essential step during regular boiler maintenance. Make sure that the ashtray is correctly
positioned when placing it back into the boiler. There are two ashtrays in the boiler, so clean both regularly.
b)
The burner grate is removable and requires regular cleaning. During the first few weeks of operation, observe how
often ash builds up on the grate and scrape it off regularly with cleaning tools. Only carry out this operation when
the boiler is deactivated (extinct).
c)
Clean the front of the boiler in the burner area as required at the same time as cleaning the burner grate.
d)
Cleaning the flue gas turbulators and heat exchanger is an essential task. Ash on the heat exchanger grates reduces
efficiency and in turn increases the flue gas temperature, i.e., more heat escapes down the chimney if the heat
exchanger is contaminated with ash.
The flue gas turbulators are removable, it is recommended to check the clearance between the turbulator plates
regularly and remove and clean them if necessary. The boiler heat exchanger can be accessed by removing the
cleaning door at the top of the boiler.
e)
Once or twice a season, check the flue gas outlet for clearance and clean it using the sweep hole that should be
located on the flue.
f)
Once a season, check the asbestos sealing cords on all doors for tightness. If they are hard and have lost their
sealing ability, we recommend replacing them.
Ask your installer to carefully explain how to clean the boiler and burner so that the boiler is operated in accordance with
the instructions given. Regular cleaning of the boiler, the burner and flue ensures maximum boiler efficiency and low fuel
