HANDLING OF THE
HEATING SYSTEM
8.1
Sealing the boiler
It is imperative that all doors are closed during
operation so that no leak air can disrupt the
combustion process. If this is not observed then
damage to the boiler may result.
8.2
Operation with low
performance decrease
Should fuel be burned in the transition period
(spring or autumn) it is vital to ensure that for low
decreased performance (less than 50%) the filling
shaft is not completely put on. Decreased
performance of less than 50%, means the boiler
and the chimney may become clogged with soot. It
is also possible that smoke may develop in the
chimney. The BioX wood log boiler should
therefore basically be operated equipped with a
correctly dimensioned buffer
(according to EN
303-5). Recommended dimensions are listed in the
document “installation instructions”.
8.3
Overheating of the boiler
Should the boiler temperature exceed maximum
boiler temperature, the safety temperature limiter
switches the controls off and the warning light
illuminates. After the equipment has cooled off
under about 75°C, the Safety Temperature Limiter
(STL) should be tripped by unscrewing the
covering cap (press the knob). Then screw up the
covering cap again afterwards. Before re-starting
the cause of the overheating should be identified
and corrected.
Thermal flow protection
If the boiler overheats, then the “thermal flow
protection” opens automatically (at 95°C) via a
sensor and cold water flows through the heat
exchanger. The boiler water is thereby cooled off
and dangerous operating conditions are prevented.
The water heated up in the heat exchanger must
be able to run away freely (directly into the waste
water channel). After the boiler water has cooled
off to about 90°C, the "thermal flow safeguard”
automatically interrupts the cold water feed. After
cooling off, the equipment pressure and/or water
level of the equipment is to be controlled and if
necessary the missing amount of water topped up.
According to DIN 4751 sheet 2, the operator is
obliged to regulate the functioning of the “thermal
flow safeguard” and the heat exchanger belonging
to it at least once a month by activating the test
button. Furthermore this safety instruction is to be
monitored once a year by the manufacturing
company or another competent organisation.
Note:
Where there is a combined non-functioning of the
“thermal flow protection” and heat exchanger, the
set-up of the equipment is not allowed.
8.4
Sweating of the boiler
During long-term operation it should be guaranteed
that the return flow temperature does not fall below
65°C. For this reason a return flow temperature
bypass is obligatory.
Note:
Corrosion damage caused by too low return flow
temperatures, do not come under the guarantee or
warranty claims.
8.5
Taking out of operation
The mains switch should not be turned to “OFF”
during the burn-off but only after complete burn-off.
