    Sep 21, 2018 · When the burner is firing, the vent valve is closed and the two block (shut-off) valves are open. This design prevents gas from entering the combustion chamber if the upstream gas-valve leaks. Where multiple boilers are operated in parallel, the fuel trains on each individual boiler must have manual isolation from the common fuel source.

  • Prepare Your Boiler for Winter Heating Season

    To release the air, switch the unit off and identify the high point vent on the boiler (if it is steam), or the high point vent on the heating loop (if it is a hot water boiler). Open the vent until you hear air hissing out. Once water begins dripping out of the bleed valve, close it back up and dry off the area.

    Conclusion. The automatic air vent is found in the piping system of water loops. If air is introduced into the water loop system it eventually finds its way to the automatic air vent where it is vented. The automatic air vents are located throughout the system. Automatic air vents may also be found throughout any hydronic loop system.
