Refer to Figure 3 for details of oil piping. All field piped components must be
mounted in the proper order as shown with the proper direction of oil flow.
CAUTION:
Oil supply pressure to the burner oil pump must not exceed 3 psi per
NFAA Codes.
NOTE:
Do not install manual valves in the return line between the pump and the
tank unless required by a specific code. If a manual valve is required, an automatic
relief valve must be installed across the manual valve to ensure that oil will bypass
directly back to the tank in the event the manual valve is inadvertently left in the
closed position.
