problems.
Serv ce h story
Faults and work ng h story can be read from bo ler nterface or
w th a computer n comb nat on w th the software and nterface
cable of the PCB.
Water leakage
The pressure of the nstallat on must be h gher than 0,8 bar,
and max mum 6 bar. F nd poss ble leaks n the system and have
these fixed.
Flue gas leakage
The flue gas d scharge and a r ntake p p ng need to be checked
for gas leakage. Also check f the p p ng s properly mounted and
not damaged. Inspect the top of the bo ler hous ng for traces of
water leakage or traces of water from the a r vent, or leak ng
condensate from the flue gas p p ng.
Gas l nes/-connect ons
The gas l nes need to be checked for gas leakage. Also check f
the p p ng s properly mounted and not damaged.
Un-assembl ng the Burner
Un-assembl ng the burner un t: Remove the 6 x M6 nuts and the
electrode cables, and move the burner un t forward. Remove the
plug of the fan cable from the fan when the burner has been
pulled half-way from the heat exchanger. D smantle the a r gas
m x ng box on the ntake s de of the fan and check the blade
wheel of the fan.
Insulat on
The nsulat on of the heat exchanger (located on the rear wall
ns de n the heat exchanger) must be nspected. If th s nsulat on
d sk shows any s gn of damage or mpa rment t should be
replaced w th a new one. Also check f there are any s gns of a
too h gh condensate level (caused by a blocked s phon) that
m ght have wetted the nsulat on several t mes. When these
s gns can be seen, the rear wall nsulat on should be replaced.
Only use the burner door nsulat on that s suppl ed by the
manufacturer.
The same procedure must be appl ed on the nsulat on and
gaskets fitted on the burner door.
Burner- and burner door gaskets
When these show any s gns of damage they must be replaced.
S phon
D s-assemble the bottom cover s phon and clean t. Check f the
s phon connect on on the heat exchanger s not blocked, and clean f
necessary. Check afterwards f the s phon funct ons properly.
Th s can be done by pour ng clean tap water n the furnace
(when burner door s removed) so t w ll ex t the heat exchanger
through the s phon. Make sure the nsulat on s not wetted.
Heat exchanger/combust on room
Check f there s any debr s/depos t n the heat exchanger. The
heat exchanger co ls can be cleaned by us ng a non metall c
brush. Afterwards the loose part cles may be removed w th a
vacuum cleaner and/or flush ng w th water. Check flow of water
out of s phon, and clean s phon f necessary. Any clean ng of the
combust on chamber w th ac d or alkal products s proh b ted!
Gas/a r rat o
Always check the gas/a r rat o by check ng the combust on figure
CO on max mum and m n mum nput. If necessary adjust these
2
figures.
Pump
If the pump s becom ng no sy (certa nly when the pump has
been work ng for more than five years) t s recommended to
replace the pump as a precaut on.
