7. TROUBLESHOOTING
Although our heaters operate with diesel fuel, when the temperatures are
below 0°c, diesel additives are required to maintain the diesel's viscosity.
typically diesel can cloud in freezing conditions and will start to gel. You
will need additives for your fuel in these conditions.
Kerosene/Paraffin does not start to gel until the ambient temperature is
around (-40°c).
