Boiler
System
7.6 Typical water system layout
The piping diagram illustrates the minimum boiler
system controls needed, the by-pass system is not
necessary, but can be used in multiple heating
temperature circuits.
Consult all national, local and building codes having
jurisdiction for other requirements regarding the boiler
system.
It is strongly suggested a decoupling devise is used
when the system flow is unknown. For multiple
boilers, consult the factory.
Check local codes regarding condensate discharge
into the common drain.
Water must be analyzed to ensure acceptable quality.
If make water consumption is unknown, the system
should be checked at regular intervals – consult
water specialists for assistance. See section 7.4.3.
When the boiler is connected to a refrigeration
system, it must be installed so the chilled medium is
piped in parallel with the boiler with appropriate valve
to present the chilled medium from entering the
boiler.
The boiler piping
system of a hot
water boiler
connected to
heating coils
located in air
handling units
where they may be
exposed to
refrigeration air
circulation must be
equipped with flow
controls valves or
other automatic
means to prevent
gravity circulation of
the boiler water
during cooling
operations.
All water piping and reliefs shall be piped to avoid any ingest of water near the boiler controls. The piping diagram
shown below does not reflect all systems consult local and national codes having jurisdictions regarding other water
system controls required.
