If resetting of tabs is needed, hold dial wheel still or force from rotating will damage coil.
FINE TUNING THE BURNER
OBSERVE THE FLAME DAILY. ALLOWING HEATER TO OVER FIRE WILL
DESTROY THE HEAT EXCHANGER AND VOID THE WARRANTY
.
UNDERFIRING
MAY LEAD TO CONDENSATION AND RUST THE CHIMNEY OR HEATER.
Due to variations in used oils, the air and oil pressure gauge setting are approximate. Final
adjustments need to be made with your specific fuel. Observe the flame pattern through the
observation port and make all adjustments while observing the flame.
1. The ideal flame is bright yellow/white in color, no visible smoke emitting from the chimney.
2. If the flame appears dull yellow and red in color, it is fuel rich and oxygen starved. Open
the air shutter on the side of the burner or reduce oil flow. Metering Pumps are factory set,
no adjusting is available.
3. Combustion air is admitted through the adjustable air bands on the side of the burner. On
models over 200,000 btu start with air band closed and face pointer at #10. On models under
200,000 btu start with air band closed and #5 for the face pointer. Add just enough air to
allow clean combustion. Excess secondary air will reduce efficiency, choke draft, make
ignition more difficult and possibly pulse or back pressure the chamber.
4. The draft and the combustion
air required for clean burning, smooth ignition, and efficient
combustion is proportional to the fuel flow rate. DO NOT exceed -.08 inches water column
draft at the breech.
5. The fuel flow rate is controlled by nozzle size and oil pressure. If the flame is not clean or
too large with oil pressure less than 2 PSI, replace the nozzle, it may have worn-out or a
smaller nozzle may work better at slightly higher pressure. Metering Pumps are factory
set, no adjusting is available.
