Oil Start-up
Burner Shutdown
Measures in Case of Trouble
Oil start-up
• Set the emergency and main switches
to „ON“.
• Open all stop valves in the oil supply
system. If a ring line system is provi-
ded for oil supply the ring line pump
must be started.
• Set the fuel selector switch to the „Oil“
position.
• Set the control switch to position „1“.
• Set the output selector switch to posi-
tion „0“ (= partial load) or „1“ (= regula-
ting load). Select the „regulating load“
position for adjusting the burner.
• The „Manual/Automatic“ selector
switch must be in its „Automatic“ posi-
tion during the start-up phase and
during operation.
• Change over to „Manual“ mode for
adjusting the burner.
• Unlock the automatic furnace control-
ler. The burner will start in accordance
with the program flow of the automatic
furnace controller. The burner is in
operation now.
Burner shutdown
1.
Set the control switch to position
„0“.
2.
Set the fuel selector switch to
position „0“.
3.
Close the gas stop valve or oil
stop valves.
4.
For short periods of shutdown the
fuel stop valves may remain in
their open positions.
5.
For longer periods of shutdown
and for inspections make sure to
set all switches to their „OFF“
positions and close the gas stop
valve and oil stop valves.
6.
Have the furnace system inspec-
ted at least once a year by the
local service company to ensure
its efficient operation and com-
pliance with the applicable air pol-
lution control regulations.
7.
Oil combustion should be without
the development of smoke and
the flame should burn steadily wit-
hout the formation of soot. No visi-
ble smoke must emerge from the
chimney and no smell of oil must
occur.
8.
Any conditions deviating from
standards and any faults should
immediately be reported to the
installer of the system and elimi-
nated without delay.
Fuel change-over
1.
Set the fuel selector switch to its
position „0“ and allow the after-
ventilation period to run down.
2.
Set the selector switch to the desi-
red fuel type.
Measures in case of trouble
Any trouble of the burner will be indica-
ted by the illuminated pushbutton switch
(red light) in the control cabinet or auto-
matic furnace controller. If the trouble
can be eliminated the automatic furnace
controller can be unlocked by pressing
any of the two illuminated pushbutton
switches causing the burner to restart in
accordance with the program. If the bur-
ner returns to its trouble position the
local service personnel should be called
to site. In case of a negative result of
the valve leak test make sure to close
the gas stop valve at once and call the
service personnel to site. The burner
may be run in oil mode until the trouble
has been eliminated.
Regular checks and maintenance
measures
• Check the gas pressure or oil pressure
on the pressure gauge.
• Check the safety time of the automatic
furnace controller by pulling out the
UV flame monitor.
• The safety time must be 5 seconds for
oil and 2 seconds for natural gas for
start-up while during normal operation
the burner must be shut down without
delay.
• Clean the flame sensors if dirt has
accumulated.
• In case the burner is operated with the
same fuel type for longer periods it
should be shortly run with the other
fuel type at an interval of 3-4 weeks.
• Clean all filters at regular intervals and
check for tight condition. Clean the oil
filter each time a fresh oil supply has
been taken in. Rinse the filter with
pure benzine or similar solvent and
blow out with compressed air. Remove
residual dirt from filter housing, if any.
Wash the filter mat of gas filters with
water (max. 40°C) adding a commer-
cial light-duty detergent if required. Do
not hose down the filters with a high-
pressure water jet. Allow the filter mat
to dry and reinstall in filter housing.
When reinstalling the filter cartridge
take care that it is located by the filter
housing groove and the filter cover.
