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
16
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.

2.6 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 tem-
perature has dropped sufficiently, the thermostat
will switch on the burner again.
• Maximum thermostat: The maximum thermostat
switches off the heater when an overheating
problem occurs. The burner cannot be switched
on again until the thermostat has been reset by
