VI. Oil Piping
A. General
1. Use exible oil line(s) so that Swing Door can be
opened without disconnecting oil supply.
2. A supply line fuel oil lter is recommended as a
minimum for all ring rates but a pleated paper fuel
oil lter is recommended for the lowest (.6 GPH)
ring rate application to prevent nozzle fouling.
3. Use Flared ttings only. Do not use compression
ttings.
4. Use of a high efciency micron oil lter (Garber
or equivalent) in addition to conventional lter is
highly recommended.
B. Single-pipe Oil Lines.
1. Standard burners are provided with single-stage
3450 rpm fuel units with the bypass plug removed
for single-pipe installations.
2. The single-stage fuel unit may be installed single-
pipe with gravity feed or lift. Maximum allowable
lift is 8 feet. See Figure 16.
NOTICE
Single-pipe installations must be absolutely airtight
or leaks or loss of prime may result. Bleed line and
fuel unit completely.
