When E is opened,it allows the hot air to pass up AA and CC,through D, and out at E, making a draft whichdraws hot air out of the heater S at BB, at thesame time drawing cold air into the heater S at nil. D is a discharge pipe of double the capacity ofC, and carries off hot air from CC out at E whenE is open. E is the main outlet for hot air, S is the hot airheater five inches deep.
