Before starting to heat the coolant, the pump will start to check if the
heating liquid is frozen. The heater will then power up to 100% to heat up
the combustion chamber and to provide proper burning temperatures.
Depending on the ambient temperature and model of the heater, this
process can take up to 15 minutes.
Hot liquid only flows after the heat exchanger is heated up. This process
takes up to 3-5 minutes depending on the ambient temperature and the
heater model.
IT DOES NOT HAPPEN INSTANTLY.
Stop the heater. When the heater is stopped, the fuel supply stops, and the combustion
chamber and the heat exchanger are vented to reduce temperature.
After the first launch, please test the heater with the vehicle/vessel running engine to
check for possible fuel and/or power supply problems.
During the first few hours of operation, the heater can emit an unpleasant
smell. To get rid of the smell, run the heater for several hours on maximum
power. Ensure good ventilation.
The insulation of exhaust pipe has to burn-in. This process can also cause
an unpleasant smell.
4.1 Automatic Control Features
1) If for some reason the heater did not start, the start-up process will be automatically
repeated. After two failed attempts the heater will be switched off;
2) If burning is interrupted during heater operation, the heater automatically re-starts.
Restarts after consecutive flameouts are performed up to three times;
3) In case of overheating of the heater coil (for example due to a blocked intake or output
of the heating unit), the heater automatically switches off;
4) If the maximum temperature of the heated coolant is exceeded (for example, due to
air trapped in the coolant system), the heater automatically switches off;
5) If voltage drops below 20V (10V) or increases to more than 30V (16V), the heater
automatically switches off.
The numbers in brackets are for the heaters with a nominal voltage of 12V;
6) If the heater switches off due to an emergency situation, a malfunction code appears
on the control panel.
7) In case one of the temperature sensors is faulty, the heater will not start, and a
malfunction code will appear on the control panel.
4.2 Vehicle alarm wire start
Heater can also be started with vehicle alarm wires in two ways:
• If the brown and white wires are connected to an impulse relay (with an impulse
between 1-3 seconds), the heater will work on previously set work mode for two hours.
• When the brown and white wire is connected continuously (for example, using a rocker
switch) the heater will work on previously set work mode as long as these wires are
connected (i.e. the rocker switch is on).
