BASIC INSTALLATION & OPERATION
This portion of this handbook applies to the Operations and Servicing of Residential Gas, Tank Type, Water Heaters, which are vented atmospherically and use a thermocouple as their electrical source.
Control: There are two gas control valve/thermostat configurations available. Both valves have similar control elements such as the Gas Control Knob & Water Temperature Dial. Both valves have high water temperature limit safety. Please note the location of the control elements on the following figures.
