INTRODUCTION

2.1 Purpose
These heaters are directly propane gas-fired
heaters with a connection for a gas bottle
with pressure controller.
The heaters are equipped with a hot air fan
and a connection for a room thermostat.
The hot air heaters have been tested at sea
level at a temperature of 20 °C.

Working principle

When the switch is set to position 1, the fan
will start. The electrical ignition is activated
and, after some time, the magnet valve will
switch on the gas supply to the burner.
The gas will be mixed with air when entering
the burner. The mixture is ignited with an
electrical spark. An ionisation pin is used to
check if a flame occurs within a few seconds.
If there is no flame within the prescribed time,
the heater triggers a fault. The ignition stops
automatically as soon as good flame has
been formed.
The heater has been equipped with a burner
automat that automatically controls the
ignition and the gas supply. The capacity can
be set as needed by manually setting the
supplied amount of gas. The capacity can
also be controlled by a modulating control.
Contact the dealer for additional information.
The heater has been equipped with a
maximum thermostat that interrupts the gas
supply in case of overheating. The
thermostat can be reset manually after
cooling down. An extra maximum thermostat
can be found behind the combustion
chamber. This can be automatically reset
after cooling down (only GA 42).
In case of a fault, the burner automat will
switch off the heater. The red lamp on the
operating panel lights up now.
A hose-breaking protection has been
mounted on the output side of the pressure
controller. This will interrupt the gas supply in
case the hose breaks.

The heater stops when the selector switch on
the operating panel is set to "0". The heater
can be used as a fan by setting the selector
switch on the operating panel to position 2.
