VENTILATION

Even though this heater operates very close to 100 percent combustion
efficiency, it still produces small amounts of carbon monoxide.

Carbon monoxide (CO) is toxic. It can build up in a confined spaces and
failure to provide adequate ventilation can be fatal.

The early symptoms of asphyxiation caused by inadequate ventilation are:

• headache • nausea

• dizziness • dry mouth or sore throat

1. Only use in well ventilated areas and make sure that ample ventilation is
present if the heater is being started following a long period without use.

2. Never attach any duct work to the front of the heater.

3. Never cover or impede airflow into or out of the heater.

WE RECOMMEND THE USE OF A CARBON MONOXIDE DETECTOR

FUNCTIONAL DESCRIPTION

A pump draws fuel from the tank and drives it to the burner under pressure.
Fuel is sprayed and atomised by the nozzle and then ignited by the burner
ignition device. A built-in radial blower provides combustion airflow while air
and fuel forms a combustion mixture. The flames heat up the front plate and
guard, thus releasing heat by radiation.

The burner pre-heater warms up the fuel before start-up and the post­ventilation function cools down the chamber after each use. No flue or
exhaust pipe is required as all combustion gasses are catalysed during
operation.

SAFETY FEATURES

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 by your dealer.

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.

sure that the heater is level and
do not overfill. Use a funnel or can with a long filling spout.

Plug the heater into any suitably earthed mains power supply.

NOTE: In cold weather, condensation may develop in the tank if the tank

is empty. Before filling the fuel tank for the first time or after
extended storage periods, vent the fuel tank of any moisture or
condensation.

POSITIONING THE HEATER

The heater must be located on a
hard, level surface to minimise the risk
of accidental tipping over or running
forward. Chock the wheels if there is
any possibility of movement.

Set the heater angle of inclination by
loosening and re-tightening the
positioning knobs on either side to
achieve the required angle of tilt.

This heater should not be used in
habitable areas.

The heater should always be positioned well away from sources of airbourne
dust, as ingress of dust into the heater may cause it to malfunction. It will be
beneficial to shield the heater from a dusty work environment

MATERIAL CLEARANCES

It is important that the heater be positioned with at least 3 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. Never place any objects on, or against the heater.

Any equipment or workshop furniture should be a safe distance away as they
