  1. 1In a gravity return system, the boiler should be placed
    1. Awell below the lowest radiator
    2. Bwell below the highest radiator
    3. Cat the same level as the radiators
  2. 2The pressure balancing device that prevents the boiler pressure from forcing he water in the boiler into the return line is called a
    1. AHartford loop
    2. BPressure equalizer
    3. CPressure control valve
  3. 3When starting up a steam heating boiler it should be filled to:
    1. A1/2 of a gage glass
    2. B1/4 of a gage glass
    3. C3/4 of a gage glass
  4. 4If the water level falls too low during operation of a steam heating boiler the operator should
    1. Ashut the boiler down
    2. Badd more water immediately
    3. Clower the flame and add water to bring it up to a safe level
  5. 5The Hartford Loop prevents the water in the boiler from

    1. Adropping below a safe level
