- That check valve is suitably designed for the duty;
The pump pressure is set at a value of 12 bar during the testing of burners. Before starting the burner, bleed the air in
the pump through the gauge port. Fill the piping with light-oil to facilitate the pump priming. Start the burner and
check the pump feeding pressure. In case the pump priming does not take place during the first prepurging, with a
consequent, subsequent lock-out of the burner, rearm the burner's lock-out to restart, by pushing the button on the
control box. If, after a successful pump priming, the burner locks-out after the prepurging, due to a fuel pressure drop
in the pump, rearm the burner's lock-out to restart the burner. Do never allow the pump working without oil for more
than three minutes. Note: before starting the burner, check that the return pipe is open. An eventual obstruction could
damage the pump sealing device.
NB : For one-pipe installation, the by-pass plug must be removed from the vacuum gauge port and the return port sea-
led by steel plug and washer.
