Maintenance and Care
The regular care and observance of
some basic prerequisites guarantee
malfunction-free operation and a
long service life of the unit.
After every heating period or in-
dependent of the previous opera-
ting conditions, the complete unit
including the combustion chamber
and burner must be cleaned of
soot, dust, and dirt.
■ For cleaning, use a clean,
slightly moistened cloth with
which you can wipe off the dirt
from the surface .
Do not use a water jet (high-
pressure cleaner)!
■ Do not use strong cleaning
agents that contain solvent.
Even in case of extreme
soiling, only use suitable
cleaning agent.
■ Clean the fuel tank regularly
and then rinse it with clean fuel
or another suitable means.
Do not use water!
■ Always keep the burner head
clean.
■ Check parts subject to wear
such as the oil nozzle, seals,
and so on, and exchange them
if necessary.
We recommend that the oil
nozzle be changed in any case
before the beginning of every
heating season!
■ Clean the tank filter in the filler
neck of the fuel tank regularly.
■ Exchange the fuel filter (ob-
serving the direction of flow)
according to its condition, but
before every heating season
at the latest. The filter is in the
direct vicinity of the tank filler
neck. Note the direction of
flow!
■ Use only clean EL heating oil or
diesel.
Look for paraffin formation!
■ Allow only authorised, expert
personnel to clean the gauze
filter in the fuel pump (only
by DZH 90) and exchange the
nozzle.
■ Regularly check the safety
appliances for correct function.
■ In case of a weakening heating
capacity, formation of smoke,
and/or bad ignition, inspect the
unit and adjust the burner.
■ Observe the regular mainte-
nance and care intervals.
