Inspection and maintenance interval
Boiler maintenance is only to be
carried out by qualied sta󰀨 with
calibrated equipment.
When replacing spare parts only
original ELCO Service parts are to
be used. For this purpose, please
refer to the Service parts list to nd
article numbers and exploded views.
Please contact ELCO.
Maintenance intervals
Maintenancehastobecarriedoutat
least after 16,000 operational hours
max. or every 4 years, whatever comes
rst.(To verify with local
service depending by installing
condition).
Depending on the intensive use of
the device, maintenance intervals will
havetobedecreasedaccordingly.For
other situations, maintenance intervals
mayalsohavetobedecreased.In
such cases, please contact ELCO for
additional advice.
Inspection and maintenance tasks
havetobecarriedoutinaccordance
with the maintenance instructions at
alltimes.Sometasksaredescribedin
these maintenance instructions. For
complete inspection and maintenance
instructions, see pages 87-93.
When carrying out maintenance
on the boiler, the gas tap has to be
closed and secured against opening.
Maintenance works
- Use the ON/OFF switch (A) to turn
theboilero󰀨;
- Interrupt the power supply to the
boiler,byoperatingthemainscircuit
breakerintheboilerroom.
- Interruptthegassupplytotheboiler.
Duringemptyingoftheboiler,itis
possiblethatapartoftheheating
waterstaysbehind.Makesurethat
any remaining heating water cannot
freeze, in case of a frost hazard.
Decommissioning
Itmaybenecessarytosettheboiler
out of service in some situations.
Switchtheboilerto“o󰀨” mode (white
colorofpowerbutton)pressingthe
powerbutton.
Thisswitcheso󰀨thefunctionsDHW
prog and Pump prog respectively.
ELCO recommends leaving the power
switch switched on to ensure that the
boilerpump(s)andthree-wayvalve
(iftted)areautomaticallyactivatedto
prevent them from sticking. The frost
protection remains active. Leave gas
supply open.
If frost, during the period when the
boiler is out of operation, is likely,
then you are advised to remove the
power from the boiler and drain the
boiler(s) and installation. In this
case: close the gas valve.
Maintenance
Pleaseobservethefollowingsafety
instructions:
All works on the boiler and
the heating facility (assembly,
maintenance, repairs) may only
be carried out by authorized
technicians, by using suitable
tools and calibrated measuring
instruments. The exchange of
components requires original
ELCO replacement parts.
Themainstopcockforgasmustbe
closed and secured against reopening.
Thecasingmustrstberemoved,
tobeabletocarryoutmaintenance
ontheboiler.Thepanelissecured
by2screwsontopofthedoor.
After loosening the screw, the casing
canberemovedbypullingandliftingit.
Follow instruction on page 82.
All equipment is preset at the factory.
An O
2
/ CO
2
control measurement must
becarriedoutduringcommissioning.
Nochangeshouldbemadeonthe
zero-point setting. The zero-point
settingmustonlybecheckedafter
a malfunction, or after an exchange
of the gas valve, the venturi or the
ventilator motor.
The zero-point setting does not
serve for setting up the combustion-
technical characteristic values.
These are made exclusively through
the O
2
/ CO
2
setting.
All gas pipes and screws must be
tested for leakproofness, using
a leak-detecting spray, whenever
maintenance or repair works have
been carried out on the boiler.
Inthisregard,pleaseobserveallof
the individual maintenance steps
documentedonpage90󰀨.,aswell
as the overview of inspection and
maintenance procedures provided on
page 92 to 93.
Inspection interval
An inspection must be carried out
at least after every 4,000 boiler
operating hours, however at least
once every year. (To verify with local
service depending by installing
condition).
An inspection consists of a visual
check, of the general condition of the
boilerandtheinstallation.
Theobjectivesofaninspectionisan
assessment of the condition of the
equipment, and an evaluation as to
when maintenance works are required.
A visual inspection can lead to a
maintenance procedure.
No tools are required during an
inspection (except for tools for
removing the panelling). If necessary,
the corresponding individual
maintenancestepsmustbecarriedout,
which are listed as of page 93.
