5.4 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
front door or the filling room 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 casing door – with
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 (2).
 Slowly open the filling shaft
(2)
 Put in the fuel
 Close the filling shaft door
and casing 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 HERZ firestar 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.
6 MAINTENANCE AND
CLEANING
6.1 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 are automatically cleaned at
each start-up or switching off of the equipment.
6.2 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 (Cleaning interval is shown at
error 27 on page 27). Rust and fly ash deposits on
the heat recovery areas (16) have a considerable
effect on the economy and performance of the
boiler.
 Removing the upper boiler casing
 Loosening screw caps and removing
cleaning cover (12)
 Loosening the fixture of the turbulators
