Gas Hot Water Heaters . For Gas hot water heaters, the unit heating system, consists of a gas burner that sits under the inner tank, combustion flumes are exhausted up thru a pipe that goes up thru the center of the inner tank and connects to another pipe at the top of the tank to carry the deadly flumes to the outside.


boiler serves as a low water cut-off (see above) and also causes make-up water to be added to the boiler should the water level drop below its control point. This type of control must be operationally tested as for low water cut-offs and also to assure that the make-up water is introduced as needed. Carefully read the enclosed literature on the Low
