  2. Automatic bleeding valve - Wikipedia

    en.wikipedia.org/wiki/Automatic_bleeding_valve

    A working system should not generate further trapped gas. Air may be drawn in if there is a small leak, or dissolved air in make-up water may come out of solution, but this generally indicates a system leak if new water is needing to be added. The most likely cause of continual gas bleeding is hydrogen, rather than air. [2]

  3. Nozzle and flapper - Wikipedia

    en.wikipedia.org/wiki/Nozzle_and_flapper

    The nozzle and flapper mechanism is a displacement type detector which converts mechanical movement into a pressure signal by covering the opening of a nozzle with a flat plate called the flapper. [1] This restricts fluid flow through the nozzle and generates a pressure signal.

  4. Infiltration (HVAC) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(HVAC)

    Smoke candles and blower-door tests can help identify less-than-obvious leaks. The Weatherization article describes methods for energy savings further. If infiltration is reduced below 0.35 ACH, it is recommended that mechanical ventilation (typically an exhaust fan or heat recovery ventilation ) be implemented.

  5. Forced-air gas - Wikipedia

    en.wikipedia.org/wiki/Forced-air_gas

    Each room has an outlet from the duct system, often mounted in the floor or low on the wall – some rooms will also have an opening into the cold air return duct. Depending on the age of the system, forced-air gas furnaces use either a pilot light or a solid-state ignition system (spark or hot surface ignition) to light the natural gas burner. [3]

  6. Draft (boiler) - Wikipedia

    en.wikipedia.org/wiki/Draft_(boiler)

    In a water boiler, draft is the difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage. [1] Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.

  8. Double check valve - Wikipedia

    en.wikipedia.org/wiki/Double_check_valve

    A dual check backflow preventer is similar to a double check valve in operation. It has two independent spring-loaded check valves. However, dual check valves usually do not include shutoff valves, may or may not be equipped with test cocks or ports, and is generally less reliable than a double check valve.
