Oil Manifold Heat Tracing; Heavy Oil Insert Heater - Honeywell Hauck MEGASTAR MS-25 Instructions Manual

L. OIL MANIFOLD HEAT TRACING
For heavy, waste, or recycled oil applications, the oil manifold piping must be heat traced and
insulated to maintain the desired temperature, and hence, viscosity, of the fuel oil (see Figure 7).
The heat tracing installed on the heavy oil manifold will aid in viscosity control and reliable main
flame ignition of the burner. The oil manifold heat tracing should consists of heat tracing cable
which is wrapped around all piping, and covered with fiberglass insulation and jacketing.
120V/60Hz power for the oil manifold heat tracing must
be supplied separately by the customer and wired into
the heat tracing power connection box.
The heat tracing cable should be self-regulating with a nominal rating of 12 W/ft (39 W/m). When
the circuit breaker switch to the oil manifold heat tracing kit is energized, the self-regulating heat
tracing should automatically switch on and off based on heat demand.
M. HEAVY OIL INSERT HEATER
Heavy, waste, or recycled fuel oils require some means of viscosity control. The Hauck heavy oil
insert heater installed in the burner's oil tube (see Figure 8) is a perfect solution to the viscosity
control problem and reliable main flame ignition of the burner at cold temperatures. The heavy oil
insert heating element, in conjunction with the oil temperature indicating controller, will maintain
an optimum oil temperature in the oil tube to ensure a reliable burner main flame ignition after an
extended shutdown of the burner.
