REMKO VRS-C Series
For reasons of operational readiness,
functional safety, economic
efficiency and compliance with
emission limits, the operator shall
have the installation inspected by
an authorised expert at least once a
year.
■
The entire unit, including the
heat exchanger, combustion
chamber and forced-air burner,
must be cleaned of adherent
dust or dirt
■
The combustion residues in the
combustion chamber and in
the heat exchanger are to be
removed by appropriate means
■
The V-belt tension and the
motor fastening must be
checked regularly
■
Wear parts such as flue gas
brakes, seals, oil filter insert, oil
nozzles etc. must be checked
and replaced if necessary
■
It is essential to follow the
maintenance instructions for
the separate forced-air burners.

■
The restrictions on exhaust gas
losses per §1 paragraph 1 of
the ordinance on small furnace
systems (1st. BImSchV must be
observed
■
Proof of the work carried
out by authorised specialist
personnel, together with
the usual logs, is therefore
mandatory
Soot deposits
Even small deposits of soot on
the heat transfer surfaces of the
combustion chamber and heat
exchanger will insulate the heat
output.
This results in a deterioration of
the combustion efficiency.
A soot layer just 1 mm thick can
cause an exhaust gas temperature
increase of approx. 50 K (see
diagram).
As can be seen from the above,
optimal burner adjustment
and regular maintenance are
indispensable for maintaining
efficiency and emission limits.
CAUTION
Prior to maintenance or repair
work, the unit must be discon-
nected from the mains power
supply.
CAUTION
It is not sufficient to switch off
the unit only via the operating
switch!
CAUTION
Adjustment and maintenance
work on the unit and forced-
air burner may only be carried
out by authorised and quali-
fied technicians!
NOTE
We recommend concluding a
maintenance contract with an
authorised specialist company
for regular maintenance and
cleaning work.
CAUTION
If the operational cleaning and
burner adjustment intervals are
not adhered to, all warranty
claims will be invalidated!
NOTE
Contact the unit manufacturer
before you replace the parts
with parts or components other
than those listed in the spare
parts list.
