Fuel pipes
The heaters has a single-pipe fuel system, so there is no need to route more than one pipe from the fuel tank to the
fuel filter located at the side of the heater. The "excess" fuel, returning from the burner, recirculates to the burner,
and additionally, the required fuel flows through the filter to the recirculation unit.
Installing the debris piping for the pre-cleaner
NOTE! The debris piping must always be routed to the opposite side of the dryer to the inlet air
opening of the dryer heater.
Debris in the inlet air of the dryer heater is a fire hazard!
Route down the debris piping for the pre-cleaner on the side of the dryer.
Install the debris piping using the parts intended for this purpose: The ventilation pipes D200 or D315 and the
elbows of 45 and 90 degrees. Support the piping at every 3–4 metres using, for example, perforated steel band.
It pays to route the debris pipe of the pre-cleaner to a cyclone (option) that separates the dust and debris from the
air. This helps keep the surroundings of the dryer clean and tidy.
The dust cyclones can be purchased from Antti-Teollisuus
