FUNCTIONAL DESCRIPTION

FUEL SYSTEM

Fuel is transferred from the tank by an electromagnetic pump, into the nozzle
and atomised. A high voltage ignition transformer sends current to the tips of
the ignition needles which provide the spark to fire the atomised fuel.

AIR SYSTEM

The fan on the back of the unit helps provide the oxygen for combustion as
well as blowing the heated air from the unit. The fans in the centre of the unit
cool the surface temperature of the heater.

SAFETY SYSTEMS

The unit is fitted with a temperature limit sensor, which is designed to turn the
heater off if the temperature should rise to an unsafe level. If the sensor is
tripped and the heater is turned off it may require a service. Once the
temperature falls back below the reset temperature, the heater should re­start.

The heater is fitted with an electrical circuit breaker to protect the internal
components from damage. If the heater should fail to work, this fuse may
require checking.

The heater uses a photocell to detect the flame in the combustion chamber.
Should the flame extinguish, the sensor will cut off the electrical current and
the heater will shut off.

The heater is fitted with a tilt switch designed to turn the unit off immediately if
it should tip over beyond a pre-determined angle.

4. When refilling, inspect the mesh
filter inside the filler neck for any
trapped contamination and clean out if necessary.

• When filling the heater, make sure that the heater is level and do not

overfill. Use a funnel or can with a long filling spout.

• Fill with a minimum of 4 litres of fuel.

POSITIONING THE HEATER

The heater must be located on a hard, level surface to minimise the risk of
accidental tipping over. The heater is not suitable for use on wood floors or
other combustible materials. It should be stood on suitable insulating material
at least 26 mm thick and extending 1m or more in all directions.

When the heater is in use, periodically monitor any buildup of heat on nearby
surfaces.

MATERIAL CLEARANCES

It is important that the heater is positioned with at least 2.5 m clearance at the
front between the heater and any obstruction including walls or other
combustible surfaces. Always position the heater facing the centre of the
room, not pointing directly at any nearby surfaces. Never place any objects
on, or against the heater.

Any equipment or workshop furniture should be a safe distance away as they
could be adversely affected by heat.

VENTILATION

The heater must only be installed in a room which is well ventilated. Ensure that
sufficient oxygen is available for combustion.

• Ventilation is essential to reduce the dangers of carbon monoxide

poisoning.
