ABSTRACT:
A combination automatic and manual bleed valve is provided and consists of adding a manual air bleed fitting into a standard automatic bleed fitting so that if the automatic bleed fitting fails the manual air bleed fitting can be used to release air therefrom. The valve also contains a removable cover so that the valve can be rebuilt in place without removal of the valve from the heating system.
