Oil Piping - New Yorker FR-HGS Series Installation, Operating And Service Instructions

Oil Piping

A. GENERAL
1. Use flexible oil line(s) so that burner door can
be opened, or 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 applications 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 the 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 7-1.
NOTICE: Oil piping must be absolutely airtight or
leaks or loss of prime may result. Bleed line and
fuel unit completely.
1. For two-piped systems, where more lift
is required, the two-stage fuel unit is
recommended. Table 7-2 (single-stage) and
Table 7-3 (two-stage) show allowable lift and
lengths of 3/8 inch and 1/2 inch OD tubing for
both suction and return lines. Refer to Figure
7-4.
