Notes:

All interconnecting pipework must have a minimum bore of 19mm (3/4") and must be

pressure rated for 42kg/cm².

Pipework connections between the burner oil system and the separate pumping set are

not supplied by Nu-Way.

Connections to the ring main on the air separator bottle air 1" BSP.

On residual fuel oil burners this pipework must be maintained at the burner atomising

temperature and in the case of class F and class G fuels must also be trace heated.
