Forced-Air Oil Burner
After loosening the 4 housing screws and the additional
2 screws (pay attention to the arrow), the assembly
base plate is removed from the housing and suspended
to the side.
The most important functional components for mainte-
nance are immediately accessible.
The assembly base plate can also be suspended hori-
zontally for maintenance, installation and replacement
of the nozzle.
Proceed as follows:
1. Hold the assembly base plate horizontally.
2. Slide the right mount sideways into the suspension.
3. Suspend the left side up into the lug..
All dimensions are approximate values in mm. The opti-
mum setting must be adjusted to the local and struc-
tural conditions.

After the nozzle has been changed and the air intake
nozzle adjusted, the assembly base plate is reinserted
in the reverse order.
Adjusting the air intake nozzle
The necessary burner pressure can be adjusted with-
out changing the outlet diameter using the adjustable
air intake nozzle depending on the combustion cham-
ber resistance and chimney draft.
Loosen the Allen screw and ro-
tate the air intake nozzle to the
desired position (pay attention to
the arrow).
“min” = lower burner
pressure
“max” = higher burner
pressure
Adjusting the secondary air
(nozzle connection rod setting)
Left rotation (+) = higher scale value
Ö
lower pressure behind the swivel disc
Ö
higher performance range.
Right rotation (-) = lower scale value
Ö
higher pressure behind the swivel disc
Ö
lower performance range.
Adjusting the pump pressure
The oil pressure must be adjusted and/or checked prior
to operation and maintenance.
Do not run the pump without oil!
1. Remove the plug on the “P” measuring connection.
Pay attention to the seal.
2. Open all oil shut-off mechanisms and switch the
burner on with the unit operating switch.
3. Adjust the necessary oil pressure in accordance with
the nozzle size and the unit capacity.
4. Remember that the required oil pressure first has to
be set for the full capacity phase (DV2) and then the
oil pressure for the start-up phase (DV1) because
the pressure adjustment DV2 can also affect DV1.
5. Switch the burner off on the unit operating switch.
6. Disassemble the manometer and reinsert the plugs
with seals.
*
The burner may only be operated at the second
level. The first level may only be used as start-up
relief!
