MAINTENANCE CHECKLIST & SCHEDULE FOR THE IDH2 RANGE

INDUSTRIAL DIESEL HEATERS

Recommended Maintenance Schedule

Due to poor quality diesel available in some regions in Australia and the continuous ‘winter diesel problems’ we face each year such as ‘wax crystallising’, which can lead to fuel line blockages etc, regular maintenance and adhering to our strict guidelines which include storing & preventative wax crystallising options is highly recommended to ensure the best performance and longevity of our Diesel Heaters.

All diesel fuel contains wax. It is considered an important diesel component because of its high cetane value. Normally the wax is a liquid in the fuel, however, when diesel fuel gets cold enough the wax starts to crystallise (i.e. solidify). If the temperature is sufficiently low, enough crystals will form to block the fuel filter, fuel line or nozzle.

How to identify waxing problems

  1. If wax has formed in a diesel fuel then it will block fuel lines and filters, it is visible as a white/yellow deposit or cloud in the fuel.
  2. The heater will be hard to start or will not start due to fuel starvation

Blending Diesel

If you are in low temperature regions such as Alpine/highland/inland or unseasonably cold weather, a diesel blend with kerosene may provide some relief to lower the cloud point.
