2 INTRODUCTION
2.1 Purpose
These convector heaters are indirectly fired
heaters with photocell protection, connections for
a room thermostat and a flue with rain cover.
The convector heaters have been tested at sea
level at a temperature of 20 °C.
2.2 Working principle
By using the selection switch j (fig. 5) the
convector heater can be used in the following
ways:
- 0: The convector heater is switched off
- 1: Fan low speed
- 2: Fan high speed
- 3: Fan low speed; burner low
- 4: Fan high speed; burner low
- 5: Fan high speed; burner high
A room thermostat can be connected to the
operating panel. This room thermostat can be
used for checking the temperature in the heated
room. The burner automat ensures safe operation
of the burner. As soon as the burner is switched
on, the fan will first blow the burner room clean.
The fuel pump sucks up the oil from the fuel tank.
A spark will develop between the electrodes. The
magnet valve will open after some time and the
nozzle will spray the oil under high pressure. This
will result in a combustible mixture that is ignited
by the spark between the electrodes. The light of
the flame that is created will activate the
photocell. This photocell checks whether a good
combustion is brought about. In case of poor or
no combustion, the photocell will switch the
burner to fault. When the combustion is good, the
ignition is switched off after the safety time has
elapsed.
The selector switch offers the possibility to
choose between high burning, low burning and
ventilate. In the high burning position, the heater
will always start up in the low position and
automatically switch to the high position after
some time.
The fan starts up slowly from the moment that the
burner is switched on. After switching off the
burner, the fan will continue to run. The fan is
switched off at the moment that the inside
temperature has dropped to a set value.

Read this manual carefully before
using the convector heater.
Keep this document with the
convector heater.
Follow the described procedures.
