Figure 9a: Recommended MPC Minimum Piping - Single Boiler Application
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.
