As required by NFPA 99 and CSA Z7396.1, oxygen systems having the source of supply outside the building shall have an inlet to connect a temporary, auxiliary source of supply for emergency or maintenance situations. This connection shall include necessary valves and allows for an emergency supply of oxygen and isolation of the normal source of supply. The inlet connection shall be a 2″ female NPT connection and be provided with a plug to prevent entry of foreign matter into the oxygen system when not in use.
A 3-piece, threaded 2″ bronze ball valve controls access to the emergency supply and the gauge indicates the pressure being introduced into the oxygen pipeline. Maximum input pressure of 100 psi.
The Emergency Gaseous Oxygen Inlet shall be housed in a weather-tight recessed enclosure.

Valves are to be provided with type-K copper extensions for connections on the pipeline, as required for installation in the main and emergency supply pipeline, in accordance with NFPA 99.
A brass body relief valve with the relief pressure set at 75 psi is required for installation in the emergency supply line. The relief valve shall be supplied factory cleaned for oxygen service and shall automatically reset after discharging to provide a positive seal.
