VI. Oil Piping
A. General
1. Use flexible oil line(s) so that Swing Door can be
opened without disconnecting oil supply.
2. A supply line fuel oil filter is recommended as a
minimum for all firing rates but a pleated paper
fuel oil filter is recommended for the lowest (.6
GPH) firing rate application to prevent nozzle
fouling.
3. Use Flared fittings only. Do not use compression
fittings.
4. Use of a high efficiency micron oil filter (Garber or
equivalent) in addition to conventional filter 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.
