A permanent live supply is required for the frost thermostat.

Fuel supply

IMPORTANT: Tuscan boilers utilise a single pipe suction lift fuel supply system; it’s essential to keep the number of joints between the oil tank and the burner to a minimum, use pipe benders rather than fittings.

Note: One of the advantages of the ELCO and pump configuration we use is that unlike a Riello burner where sometimes a deaerator like a Tigerloop is essential they are absolutey not required with a Tuscan Boiler; they will of course act as a ‘plaster’ masking faults with the fuel supply system. Better to resolve the problem; deaerator’s have their own inherent problems.
