Common user issues

E01 - Check your battery voltage and re charge as required.
If you have a split charge system, start your vehicle to
increase supply voltage.

E08 - Add more fuel to tank.

E10 / E11 - Combustion error, attempt to restart 3 or 4 times.
This can be caused by running below 1/4 tank
of fuel even though you have now refilled.

It can also be caused by a blocked exhaust or not following
low temperature running procedure.

Preventative maintenance

Please run your heater for approx 5 minutes at full
power / temperature every week / 10 days
if not being used to keep fuel supply fresh.

Low temperature running

If running at low temperature for prolonged periods
I.E overnight, please increase to full power for 5 mins
before turning off to clear chamber.
