Because of postive pressure in the burners, it is difficult to light with a torch unless the air is turned very low and a strong pressure torch is used. Add 10% to flame dimensions shown for operation with #6 oil. Subtract 10% from flame dimensions shown for reduced port tile "R" version. Fuel gas can be increased to match the cold air capacity with no change to burner components however, fuel oil flow is limited as shown in the table above. Consult North American for special atomizer options.
