NOTES:

1.All piping is schedule 40.

2.Pipe sizes listed are based on a 20°F or 40°F Delta T (temperature rise across the boiler).

Select one to match application.

3.When specified supply/return piping size is less than 4”, install appropriate size reducer directly onto boiler supply and return manifolds.

4.Drain valve - ball valve preferable, gate valve acceptable alternative (supplied by others). Minimum valve size per ASME Code is 3/4” NPT.

5.Swing joints may be piped over the top of the boiler if space is limited.

6.System design must accommodate the above Boiler Operating Requirements.

7.Diaphragm expansion tank shown, but other types of air elimination systems may be used.
