C. OIL SYSTEM
The V series burners pump high pressure fuel oil to the spray nozzle resulting in combustion-ready finely
atomized oil spray.
Fuel Unit
Standard V13-55 have an oil pump flex-coupled to the blower motor; these units may be
optionally equipped with a remote pump.The larger V60-168 use a remote pump with separate
motor.
Oil Nozzle
Pump pressurized oil discharges from the nozzle in a fine conical spray pattern. The burner's
nozzle is sized to provide the burner's high fire rate, rated gallons per hour (gph). Smaller gph
nozzles may be used to match burner output to a heat exchanger's required input. Models V13-
34 are supplied with simplex nozzles (return flow nozzles optional on V25-34). Models V35-
168 are supplied with return flow nozzles.
Nozzle Adapter
A nozzle adapter provides the means for connecting fuel lines with the nozzle.
Oil Solenoid Valves
Two normally closed (N.C.) and one normally open (N.O.) solenoid valves are part of the oil sys-
tem on LHO and LHL burners. The two (2) N.C. valves provide positive shutoff of fuel oil while
the one N.O. valve cycles the burner to high fire when closed.
Oil Metering Valve
The firing rate is controlled by an adjustable metering valve in the return line. At low fire, the
metering valve is open, and is closed at high fire.
Oil Filter
The oil filter prevents foreign matter from entering the burner oil system. This item is provided
as an option and shipped loose with the burner.
