AGA Rayburn manufactures cast iron cookers that provide consumers an alternative way to meet their cooking needs. The cookers have ovens and hotplates that you can control individually through the touch of a button. Each oven has a separate heat source and an energy-efficient design. Although a low-rate fire burns continuously in the AGA, you can adjust the oil during long periods of disuse or when more heat is needed.
Fill your oil tank with at least 300 gallons of oil.
Open all of your oil valves so oil enters the control valve and check the level of the burner oil. Push the lever marked "D" on valve "A" and turn knob "C" until it reaches "6."
Wait for 10 to 15 minutes and watch while the oil settles. The depth of the oil should be approximately 5 to 6 millimeters deep in the burner base.
Tighten or loosen the screws that are located between the mounting bracket and valve to adjust the depth of oil in the burner base.
Check the oil level again.
Disconnect the pipe that feeds the oil into the burner base. Install the adapter that measures the drip feed.
Turn the control valve knob to "6" once again and let the oil flow for two minutes. This sets the low fire rate.
Repeat this process on the broilers and inner cooker burners.
Light the stove with the safety oil lever off. Listen for the audible click when you depress it. Move the knob that controls the oil flow to "1" and watch for the flame to develop as the oil runs into the pot.
Leave the stove lit for one to two hours or until the fire settles, and adjust the oil flow rate if the burner does not run appropriately.
Watch for the flame color. Set the flue vacuum to .01 to get a blue flame at position "1" on the flow knob. If your flame is blue when the flame is low and the catalyzer is red when the flame is high, you are at the right flame rate. If you see a yellow flame, adjust the flow rate to add more oil and reduce the amount of air.
