Unit Shut Down
Starting
Heating Mode
1. Turn the customer-supplied main switch or the fuse
on.
2. Open the fuel supply.
3. If the unit is taken out of op-
eration for a longer period of
time, the customer-supplied
main switch or the fuse
should be switched off and
the fuel supply closed off.
When heat is necessary, the forced-air burner switches
on automatically. The air supply fan only switches on
once the target temperature has been reached. This
prevents cold air from being blown out. The unit now
functions fully-automatically to maintain the set room
temperature.
3. Set the operating switch to
“Heizen” (heating) or “
I
”.
4. Adjust the room thermostat
to the room temperature you
want.
1. Set the operating switch to
“Lüften” (fan) or “
II
”.
2. Keep in mind that the unit’s
fan runs continuously.
It is not possible to control it
with a thermostat
Ventilation
1. Set the operating switch to
“0”.
2. Keep in mind that the air sup-
ply fan continues running to
cool down the heat-exchanger
and can run several times
before the unit is finally
switched off.
G
Never interrupt (except in emergency situations)
the power supply until the cool-down phase is
completely finished.
Our guarantee does not cover damages caused to
the unit by overheating.
Maintenance and Service
The operator must have the unit checked and serviced
as necessary, at least once a year, by a representative
of the manufacturing company or another authorised in-
dividual in accordance with the operating conditions.
The units must be checked for operational readiness,
functional safety, efficiency and compliance with emis-
sion limits.
The operator must be informed if defects are found. He
must then have the unit serviced immediately or its
components replaced.
The following applies:
Maintenance work on limiting devices, self-
adjusting devices and flame monitoring devices as
well as on other safety mechanisms may only be
performed by the respective manufacturer or his
representatives.
On the other hand, the individual contracted to
service the unit may only replace components or
assemblies with those provided by the manufac-
turer or his representatives.
Regular Cleaning and Maintenance
Dust and dirt must be cleaned from the unit including
from the heat-exchanger, combustion chamber and
forced-air burner. Combustion residue in the combus-
tion chamber and in the heat-exchanger must be re-
moved.
The V-belt tension and the motor mount must be
checked on a regular basis.
Parts that wear out, e.g. flue gas brakes, seals, oil filter
inserts, oil nozzles, etc. must be checked, cleaned and
replaced if necessary.
G
Adjustments or maintenance work on the unit or
forced-air burner may only be performed by
authorised personnel!
G
Prior to doing any maintenance or repair work on
the unit, unplug it from the power supply. It is not
adequate to switch off the unit with the operating
switch!
Important Information on Servicing the Unit
◊
If the cleaning and burner adjustment intervals are
not observed, the guarantee becomes null and void.
◊
It is therefore absolutely necessary to keep records
that work has been performed by authorised person-
nel in addition to creating standard protocols.
◊
We recommend entering into a maintenance con-
tract for the regularly scheduled maintenance and
service work.
G
After maintenance work is complete, conduct an
electrical safety test.
