WARNING:
To calculate the length of the pipework all the straight parts, curves, up and down pipes must be taken into consideration.
The static suction height is the distance between the standing valve and the axis of the burner pump. Negative pressure must not
exceed 0,45 bar; if negative pressure is greater pump operation may become faulty, leading to an increase in mechanical noise and
perhaps even breakage. All oil ring installations must comply with the local safety rules existing in the country of installation
SUCTION LINE LENGTHS FOR PIPE SYSTEMS
The burner is equipped with a self-priming pump which is capable of feeding itself within the limits listed in the table at the side.
