The photocell should be cleaned at least once per heating season or more depending on conditions of use. Use a cotton swab dipped in
water or alcohol to clean the lens of the photocell. The positioning of the photocell is critical to its correct operation. See fig.11 for the
correct installation.

fuEl filTER (See fig.12)
The fuel filter should be cleaned at least twice per heating season by rinsing it in clean paraffin or kerosene. Use of contaminated fuel
will make it necessary to clean the filter more frequently. To remove the filter first squeeze the legs of the fuel line clip and move it up the
fuel line. Ease the fuel line from off the filter head. Turn the hexagonal head of the filter 90° anti-clockwise and ease it upwards and out
of the tank.

lonG TERM SToRAGE
If the heater is to be stored for a long period of time, drain the fuel
through the fuel cap opening. Rinse and swirl a small amount of fuel
within the tank and then empty it fully. When you come to use the
heater again do not use old fuel which has been stored from the
previous season. Use of old fuel can damage your heater.
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.
