12.0 WATER CONNECTIONS
12.1
GENERAL
Recommendations for the water circulation system are given in BS6644 and CP 342. The following notes are of particular importance.
1.
Circulating pipework not forming part of the useful heating surface should be insulated. Cisterns, expansion vessels and pipework
situated in areas exposed to freezing conditions should also be insulated.
2.
Drain valves must be located in accessible positions that will permit draining of the entire system including the unit and any additional
storage vessel.
3.
Tapping sizes for connection to the water system are detailed in 4.1.1Technical Data
4.
Ideally, individual valves should be fitted to each unit to enable isolation from the system. The arrangement must comply with the
requirements of BS6644.
5.
Typical pipework schematics are available from Lochinvar Limited upon request.
