For all heavy fuel oil applications, i.e., any oil requiring heating for
use, oil piping must be heat traced (electric or steam) and
insulated. Self-regulating heat tracing is recommended to maintain
the desired temperature of a given fuel oil to achieve 90 SSU (1.8 x
-5

m
/sec) or less at the burner. Electrical heat tracing with a
nominal rating of 12W/ft (39W/m) covered with a nominal 2" (50mm)
fiberglass type insulation is sufficient for most applications.
