6. FUEL PUMP
6.1
A standard fuel pump is used on the Pioneer burner.
Therefore, it is important that discharge pressure is monitored
very closely. It is recommended that a 10 micron filter with a
vacuum gauge be installed before the fuel pump using a
flexible oil line (the flexible oil line is recommended to easily
service the burner) between the fuel pump and filter.
6.2
The fuel pump on the burner is factory set at 165-170
PSI. This pressure is necessary to get the desired oil flow to
maximize the nozzle output capacity for the FCX.
Do not
exceed 175 PSI.

There is a solenoid valve on the fuel pump to initiate a
pre-purge after the burner control starts airflow. The
Honeywell microprocessor control R 7184 P has a 15- second
pre-purge period. Factory wiring does not allow for a post
purge. Follow specifications on the R 7184 P control to
troubleshoot any control problems.
7. FUEL
7.1
ASTM D396 No. 1 or No. 2 fuel must be used on the
Pioneer burner. A new oil tank is suggested with all
installations. If a new oil tank is not installed, then the old oil
tank should be less than ten years old and it should be
checked thoroughly to ensure that sludge or other
microbiological impurities are not present. Oil tanks greater
than ten years of age MUST be replaced before the
installation is completed. Vacuum readings greater than 5"
Hg must be avoided. Refer to the Suntec Installation Service
Manual included with this document.
Note: For the installation of the oil tank and oil lines, refer to
local codes. Also, some installations may require an Oil
Safety Valve (refer to local codes).
