From tank To tank Fig. 7 - Double-pipe system The burner is supplied with filter and flexible hoses, all the parts upstream the filter must be installed by the customer. As far as the hoses connection, see the related paragraph.. -
Page 10: Determining The Diameter Of Oil Supply Pipes
To change from a 1-pipe system to a 2-pipe-system, insert the by-pass plug G (as for ccw-rotation- referring to the pump shaft). Caution: Changing the direction of rotation, all connections on top and side are reversed. PG60 - PG70: Suntec AJ6 - PG81: Suntec J6 Suntec AJ6... -
Page 11: About The Use Of Fuel Pumps
C.I.B. UNIGAS - M03997CB Bleed Bleeding in two-pipe operation is automatic : it is assured by a bleed flat on the piston. In one-pipe operation, the plug of a pressure gauge port must be loosened until the air is evacuated from the system. About the use of fuel pumps Make sure that the by-pass plug is not used in a single pipe installation, because the fuel unit will not function properly and damage to the pump and burner motor could result. -

Page 13: Connecting The Light Oil Flexible Hoses
C.I.B. UNIGAS - M03997CB Connecting the light oil flexible hoses To connect the flexible light oil hoses to the pump, proceed as follows, according to the pump provided: remove the closing nuts A and R on the inlet and return connections of the pump; screw the rotating nut of the two flexible hoses on the pump being careful to avoid exchanging the inlet and return lines: see the arrows marked on the pump that show the inlet and the return (see prevoius paragraph). -
Page 14: Adjustments
C.I.B. UNIGAS - M03997CB ADJUSTMENTS ATTENTION: before starting the burner up, be sure that the manual cutoff valves are open. Be sure that the mains switch is closed. Before starting up the burner, make sure that the return pipe to the tank is not obstructed. Any obstruction would cause the pump seal to break. - Page 15 C.I.B.
