Fuel Flow Measurement
If your heater is burning rich (making soot or smoking) or burning lean (flames not
burning above the top burner ring), adjust the flow as follows regardless of what type of
fuel:
1) Unscrew the compression nut from the bottom of the valve and bend away the
copper fuel line. Allow the oil to drip into a cup or container.
2) Turn the valve knob to the #1 setting. Measure the quantity of oil dripping
slowly from the fuel outlet.
Knob Setting 1 (all models) 1 teaspoon in 60 seconds (4 c.c.'s per minute)
Atlantic 1 teaspoon in 53 seconds (5 c.c.'s per minute)
Beaufort 1 teaspoon in 45 seconds (6 c.c.'s per minute)
Fuel Flow Adjustment
Refer to the Oil Metering Valve diagram. The height of the valve-adjusting knob will
determine the quantity of oil exiting from the valve outlet. The height is determined by
the length of the metering screw against the fuel ramp on the main casting of the valve.
Remove the anti-vibration set screw (5/64 allen) located in the center of the brass nut on
top of the knob (turn counterclockwise). The adjusting screw may be (5/64 allen) or a
very small flat head. Adjust 1/8 turn at a time. After making an adjustment return the set
screw using needle nose pliers to hold the adjuster from turning when locking set screw
in place.
