fuse replacement
7.9.
note: this is a fuse protected heater.
7.9.1.
if your heater fails to ignite check the fuse as shown in fig.14 before contacting your
local service agent.
warninG! unplug the heater from the mains power supply before attempting any
‰
maintenance work.
7.9.2.
remove the control panel screws and lift off the side panel to reveal the printed
circuit board.
7.9.3.
disconnect switch wires from the power switch.
7.9.4.
remove fuse from holder as shown.
7.9.5.
replace fuse with one of the same specification.
warninG! do not substitute the fuse with one of a higher or lower current rating as this
‰
may result in a fire hazard.
7.9.6.
reconnect switch wires to the power switch.
7.9.7.
replace side panel.

8.1.
Although our heaters operate with diesel fuel, when the temperature is 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.
problem
Heater fires, but main
PCB shuts heater off after
a short period of time.
Lamp is flickering and LED
display shows "e1".
Heater will not operate or
motor runs for a short time.
Lamp flickers and LED display
shows "e1".
fan does not operate when
heater is plugged in and
Power switch is in the "on"
position. The lamp is flickering
or on and led display shows
"e1" or "e2".
Lamp flickering and LED
display shows "e3".
