Vitoflex 300-RF Service & Maintenance
Cleaning
(continued)

Pneumatic cleaning system (optional)

- Operation and maintenance of the air compressor
(optional) according to the manual that comes with
the system.
- For a field supplied air compressor, the compressor
has to be suited for continuous operation or be
secured against continuous operation (e.g. timer
for limiting running time).
- Continuous operation of the compressor indicates
leakage in the air system. Check air supply line and
valves for leakage.
Regularly drain condensation water
in the compressed air distribution bar.

Shutdown

Boiler

Heat exchanger:
- When the Vitoflex 300-RF is not in operation for a
long period (such as for summer breaks), be sure to
carefully clean the heat exchanger with a steel brush
as required.
- If the heating room is moist or there is any other
atmosphere that promotes corrosion (e.g. poor
ventilation, residual enamel near the heating room,
etc.), spray the heat exchanger with biodiesel
after cleaning.
- If there is a danger of frost, empty the heating
system or add antifreeze.

Extraction and conveyance systems

When the Vitoflex 300-RF is not in operation for a long
period (such as for summer breaks), it is recommended to
empty the fuel extraction and conveyance system of all
fuel to avoid corrosion of the equipment and decay of the
wood fuel. Refill with new fuel after checking the system
and before the boiler startup.

Control system

Even when the Vitoflex 300-RF is not in operation for long
periods, the power supply to the control system should
not be interrupted (do not turn off the main switch).
- The "intermittent control system" switches on the
boiler pump for five seconds every 24 hours.
This prevents the pump from jamming during long
stand stills and prevents expensive repairs.
- Prevent the formation of condensation in the oxygen
sensor.
- Extend the service life of the buffer battery.

Ash disposal

- Ashes should be stored in covered metal containers
on non-combustible floors away from combustible
material.
- Comply with customary laws and local regulations
on ash disposal.
