Sound Pressure Levels
Sound pressure levels were measured at 4-
1/2’ above the floor and 3’ from the boiler at
the front, rear and two sides. See Table 7 for
decibel readings.

Pump and Piping Requirements
Pump piping and system piping must meet
the requirements of local codes and
jurisdictions. Good engineering practices
should be followed and considered for each
piping system used.
It is advised that the circulating pump for
each boiler be installed as close to the boiler
as possible in the line to the return connection
such that system water is pumped towards the
boiler.
Installing circulating pumps so that the water
is pumped away from the boiler is rarely
recommended.
Means to eliminate air from the boiler/piping
systems is a must. It is advised that an air
separator be installed as close as practical to
each boiler in the outlet pipe. Further, an air
vent should be installed at all high points
throughout the piping system.
It is recommended that a water meter be
installed in the make-up water system to the
boiler system. Scheduled recording of the
water meter register will show an indication of
a potential slow system leak in addition to
providing insight into any system problems.
Also, make-up water as well as water for the
initial system fill should be provided through
a water softener. Additionally, chemical
treatment of the system water is advisable.
Contact a qualified boiler water chemical
treatment company for their
recommendations. See section 3.8 for more
information.
See Appendix G for boiler water flow
pressure drop data and Appendix F for typical
boiler piping arrangements.
3.5.4.1
Water Flow Rates (Variable Primary
Pumping Systems)
Variable primary pumping systems shall be
capable of delivering no less than the
minimum and no more than the maximum
specified in Table 8 and Table 9 for each
boiler connected in the system.
