Re-heating
Depending on the wood type and quality the
burning time of a filled boiler by nominal capacity is
about three to eight hours.
By intermediate opening of the
fill shaft door the combustion is
disturbed. These can lead to a
poorer combustion behaviour
and excessive escape of flue
gas.
Filling should burn
down completely
To refill fuel or to check the level:
Open the filling shaft door
slowly – the ventilator
going at full speed, so that
the flue gas is sucked out
via the smoke flue channel
by opening the filling shaft
door.
Put in the fuel
Close the filling shaft door.
A quick covering of the
glow with wood logs
reduces the leakage of hot
gases from the filling
room. Refill only as much
fuel as for the energy
absorption capacity of the
system is permitted.
Pay attention to the lower
buffer temperature. If the
buffer is already loaded
(lower buffer temperature
over 40°C), please avoid a
reloading of fuel. By too
slight heat consumption
the risk of tar formation
and overheating of the
boiler is existing.
The Solarbayer BioX special boiler is characterised
by its long combustion duration. It does not have to
be re-filled with fuel at frequent intervals. It is
recommended that the
filling shaft only be filled
according to the heating requirement
, so that
frequent opening of the filling shaft door does not
have a negative effect on combustion.

MAINTENANCE AND
CLEANING
10.1
De-ashing and cleaning
general
In order to counteract increased fuel consumption,
rising flue temperature, decreasing efficiency level,
etc., we recommend that the boiler be cleaned at
frequent intervals. The combustion chamber only
has to be cleaned every two to six days, depending
on the type of fuel used. The heat recovery areas
must be cleaned manually at each start-up or
switching off of the equipment.
10.2
Cleaning of the heat recovery
areas (manual)
The heat exchanger pipes are to be checked
regularly for soiling and should be cleaned
manually if required. Rust and fly ash deposits on
the heat recovery areas have a considerable effect
on the economy and performance of the boiler.
For an optimized regular cleaning SOLARBAYER
recommends retrofitting the automatic heat
exchanger cleaning system for the BioX boiler. The
boiler
control
monitors
the
turbulators
independently and cleans them at regular intervals.
The resulting ash must be removed via the ash
door.
Nevertheless, a careful cleaning of the pipes with a
brush at regular intervals (every 1000 operating
hours) is necessary.
10.3
Cleaning of the combustion
chamber
This only has to be cleaned every two to six days,
depending on the type of fuel used. When burning
fuels with a high proportion of fly ash (e.g. paper,
cardboard, bark, etc.) on combustion, the
combustion chamber should be cleaned more
frequently:
