BOI L ER FEED SYSTEM DATE: 4/3/03 REP:2/1/99 1.4.5 OVERFLOW CONNECTION The overflow connection should be piped to an approved drain for gravity flow of any water that may reach that level in the tank. The purpose of the overflow connection is to keep the tank from being flooded in case a high level condition occurs in the unit. If a feed system is used in proper operation, the overflow should not need a trap or any valve for proper discharge of the water into an atmospheric drain. 1.4

BOI L ER FEED SYSTEM DATE: 4/3/03 REP:2/1/99 FILTRATION For some old systems, there is a reluctance to clean the piping because of the possibility of leaks occurring in badly corroded lines. Should the customer refuse cleaning, it is necessary to install filtration equipment. Install either a fibrous filter or a centrifugal filter in the boiler return piping. This will collect and remove sediment from the system. A booster pump may have to be installed as well to overcome the additional

BOI L ER FEED SYSTEM DATE: 4/3/03 REP:2/1/99 Idle boilers are vulnerable to attack when air contacts untreated wet metal surfaces. To prevent corrosion, the metal must be protected by either keeping the surfaces completely dry or by excluding air from the system. PRE-OPERATIONAL CLEANING AND LAY-UP Proper lay-up techniques must be used on an idle system even if it has never been in operation. Before pre-operational lay-up, the boiler system must be chemically cleaned as outlined in Se
