Oil Piping

A. GENERAL.
1. Use flexible oil line(s) so that burner can be
removed without disconnecting the 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
firing rate application to prevent nozzle fouling.
3. Use Flared fittings only. DO NOT use
compression fittings.
4. Use of a high efficiency micron filter (Garber or
equivalent) in addition to conventional filter is
highly recommended.
