2.1
The heaters are indirect fired heaters with
photocell control and connections for room
thermostat and flue with raincover.
The heaters are provided with a radial air fan.
The heaters are tested at sea level at a
temperature of 68 °F.
2.2
The heater is provided with two electric motors.
One electric motor drives a fuel pump and the
combustion air fan. The other motor drives the hot
air fan. The pump draws the fuel from the tank.
The hot air fan blows air into and around the
burner chamber.
The magnetic valve opens 40 seconds after
switching on the heater and the fuel flows into the
nozzle.
A spark between the electrodes ignites the
atomised fuel. The light from the flame activates a
photocell. After the safety time the ignition
switches off.
After a while the digital thermostat switches on the
motor of the hot air fan and blows the hot air out
of the heater.
The magnetic valve closes when you switch off
the heater, or as a result of a fault, the flame
stops.
The hot air fan runs until a thermostat switches
the fan off: the cooling cycle is complete.
It is possible to use the fan as a blower only.

Diesel.
• Do not use gasoline or crankcase
oils.
• Place the separate fuel tank at least
7 ft from the heater.
• Do not fill the tank while the heater
operates.
• When the static pressure is not
within the limitation of the heater,
this can cause damage to the fan
motor or heat exchanger.
