INTRODUCTION
2.1
Purpose
The heaters are indirect fired heaters with
photocell control and connections for room
thermostat and flue with rain cover.
The heaters are provided with two air fans.
The heaters are tested at sea level at a
temperature of 20 °C.
2.2
Operation principle
The heater is provided with two electric motors.
One motor drives the main fan. The other motor
drives the fuel pump and the fan for the burning
air. The fuel pump draws the fuel from the tank.
The fan blows air into the burner chamber. The
magnetic valve of the burner opens and the fuel
flows into the nozzle 40 seconds after the heater
is switched on. A spark between the electrodes
ignites the atomised fuel. The light from the flame
activates a photocell. After the safety time the
ignition switches off. When the air in the heater
reaches a certain temperature, the thermostat
switches on the motor of the main fan, which
blows the warm air out of the heater.
The magnetic valve closes when you switch off
the heater, or when the flame stops as a result of
a fault. The main fan blows until the thermostat
switches the main fan off. Then the cooling cycle
is complete.
This describes the heater in automatic mode. You
can also use the heater to blow continuously with
or without heating.

The heater has a single fuel pipe system for the
fuel supply. On request the system can have a
twin-pipe system for fuel supply and fuel return.

Digital thermostat
The digital thermostat (B) has three functions:
•
Fan thermostat:
The thermostat will switch on the fan as soon
as the heater reaches the set temperature.
After switching off the heater, the fan will
continue to run. The fan cools down the
heater to prevent damage by overheating.
The fan automatically stops.
•
Burner thermostat:
The burner thermostat stops the burner as
soon as the temperature of the heated air
becomes too high. When the air temperature
has dropped sufficiently, the thermostat will
switch on the burner again.
