Operating Tips
Every time the position of the knob on the oil metering valve is moved (fuel), the air will
need adjusting in order to have the correct fuel to air mixture. This will:
1 Keep the burner, combustion chamber, flue pipe, and your deck
clean
2 Keep the draft strong against down drafts
3 Keep the correct heat in the correct part of the combustion chamber
On the lower settings the burner needs less air. To reduce the air, adjust the barometric
damper open wider (pg-6), turn down or turn off the fan, and add more fuel even if you
do not want the heat. It is better to make too much heat and dissipate it than to run the
burner too lean (flames in the burner) as this will result in hard carbon build up and soot.
The burner was designed to burn a certain amount of fuel on low and if less fuel is burned
(flames below the ring), the burner will not burn clean.
Turning up the valve in small increments will help the draft catch up with the fuel
increases, and this keeps a good fuel to air mixture, and that helps in reducing soot.
When on medium to higher settings when the flames are looking orange with black tips,
turn the fan on, but use the lowest fan speeds and increase air slowly until the flames
start to turn yellow and are more vibrant. If you turn the fan on too much air will burn off
all the fuel and the flames will end up below the top burner ring. If you do not have a fan
the fuel increases will have to be done at slower increments.
After the heater/stove is well heated and cabin temperature is reaching comfort, the valve
body and the fuel in it will start to warm and the heater/stove will start to burn hotter. An
adjustment will have to be made to turn down the fuel to the lowest setting so that the
burner will have all the flames above the ring and not the setting on the valve. The
number will only be used as a reference so you now know how low you can go and still
have a clean burn. This is very noticeable when the fuel is in a very cold temperature.
When using the fan keep in mind that low settings require little or
no air.
On the medium settings very little air or still none depending on if you have a longer
chimney. The higher settings need air to keep the flames yellow but as the heater gets
hotter the fan air can be reduced as the chimney will start to pull more air on its own.
With no fan the highest setting may be too rich and a higher chimney will be required or
fuel setting has to be reduced.
While lighting the burner you can leave the superheater in the heater, give it a twist back
and forth to clear the oil inlet, then throw the lighted tissue in. The tissue will land on the
