The intangible fire is applied as the main component of principles used as a tool to clarify the Dhamma teaching in 2 folds : one is compared with evil deeds that must be completely destroyed from the body and mind,  another is compared to the good deeds that must be practiced. The good deeds are 3 types of fire : Fire that should be respected (parents), Fire that should be worshiped (ascetics), and Fire that should be protected (spouses’ children  and  dependents).
