7.2 Cleaning

Periodic cleaning is essential for proper and safe
functioning of the air heater. Depending of the
accumulation of excess soot, dust and dirt the
cleaning operation should be performed after
seasonal use (every 12 months) or at the end of
each production batch (e.g. 6 weeks).
More frequent cleaning operations may be needed
in case:
• the air inlet is obstructed by dust, dirt and
feathers;
• poor quality fuel is used;
