Inspirator Calibration

The main function of the inspirator is to allow fresh air to mix with the gas before it
enters the nozzle of the burner. The amount of air that is mixed with the gas governs
how the flame will burn. The correct adjustment of the air/gas mixture is critical to
achieving a suitable flame.

After Preheating is completed, adjust the Air/ Gas disc on the inspirator to achieve the
following flame characteristics:
 For the Tube burner, the flame should reach the roof of the oven.
 For Natural Gas, all flames should be blue at the base with light yellow tails,
 For Propane or LPG, the flame will be mostly light yellow. The Air/ Gas mixture
disc will need to be nearly fully open for Propane. (Deep yellow to orange is NOT
correct and will deposit soot on the roof of the oven.)

By screwing the disc upwards,
it limits the amount of air that
