Digital thermostat
The digital thermostat (B) has three functions:
•
Fan thermostat:
The thermostat will switch on the fan as soon
as the heater has reached the preset
temperature.
After switching off the heater, the fan will
continue to run. The fan will cool down the
convector heater to prevent damage by
overheating. The fan will automatically stop.
•
Burner thermostat:
The burner thermostat will stop the burner as
soon as the temperature of the hot air has
risen too much.
When the air temperature has dropped
sufficiently, the thermostat will turn on the
burner again.
•
Maximum thermostat:
The maximum thermostat will switch off the
heater completely if an overheating problem
has occurred in the convector heater. The
burner cannot be switched on again until the
thermostat has been reset by pressing the U
key for two seconds.

PREPARATIONS
3.1
Removing the packaging
1.
Remove the packaging from the heater.
2.
Hoist the heater for transport to the place of
use.
3.2
Installation
1.
Make sure that the heater is placed
horizontally.
2.
Connect the fuel supply to the fuel filter(A),
see fig. 8. Use a hose clamp.
Diameter of the hose (A): 0.4 inch internal.
3.
Fill the tank with fuel.
4.
Make sure there is sufficient distance
between the wall and the air inlet. Minimum
distance is 3.2 ft.
5.
Make sure that the heated air can flow
without obstruction. The minimum distance
between the outlet and any obstacle is 16 ft.
6.
Check the ventilation surface area: for each
3500 BTU a surface of 4 inch
2
is needed.
Caution
Hoist the heater according the
instruction on the stickers.
Caution
Use only No.1 fuel, No2 fuel or Diesel.
Caution
•
Gas oil tends to thicken at low
temperatures. This can block the
filters. Add a maximum of 15%
paraffin to the fuel at temperatures
below 20 °F, or keep the fuel frost-
proof.
•
Do not place the tank in the hot-air
flow.
