rate prior to being energized (opened). This feature allows a slow three second increase of
air pressure from 0 to 12 psi going to the nozzle. This is when a soft flame is established.
After the coil is energized (opened) the full flow of compressed air will flow to the air
regulator and 20 psi is sent to the nozzle for a more intense flame.
10. Opening the combustion air bands is acceptable for clean combustion of the fuel. This will
create a shorter and brighter flame. Open the bands only enough for a clean flame.
Excessive air will cause irregular ignition or blow out flame.
11. Observe flame. A proper flame in Model 155, 200, 245, 315 will extend 1/4 to 1/3 the way
down chamber approximately under where the blower is mounted. Three pass heater
designs Model 235, 350, 500 will have flame approaching the target wall.
Excessive flame
in any heater will damage metal, burn poorly, and void warranty.
If an adjustment
is needed, take a portable phone to the heater, call your equipment dealer and explain
the situation. They will assist you to set oil or air flow for proper flame.
On non-metering pump heaters to adjust flame loosen nut on brass oil
regulator and slightly turn screw while observing flame.
On metering pump heaters they are factory set for oil flow. If you
believe the flame is improper advise your dealer, they can confirm you have the proper
pump and advise you of options. If there is a brass oil pressure regulator on the burner it is
not required when using a metering pump, the regulator may be removed. If the brass oil
regulator is left on the burner turn its screw full clockwise to 100% flow, it will then have no
affect on oil flow.
