A.
DESIGN A PIPING SYSTEM and install boiler which
will prevent oxygen contamination of boiler water and
frequent water additions.
1. There are many possible causes of oxygen
contamination such as:
a. Addition of excessive make-up water as a result
of system leaks.
b. Absorption through open tanks and fittings.
c. Oxygen permeable materials in the distribution
system.
2. In order to insure long product life, oxygen sources
should be eliminated. This can be accomplished by
taking the following measures:
a. Repairing system leaks to eliminate the need for
addition of make-up water.
b. Eliminating open tanks from the system.
c. Eliminating and/or repairing fittings which allow
oxygen absorption.
d. Use of non-permeable materials in the
distribution system.
e. Isolating the boiler from the system water by
installing a heat exchanger.

3. Connect System supply and return piping to
boiler. See Figures 5 and 6. Also, consult
I=B=R Installation and Piping Guides. Maintain
minimum ½ inch clearance from hot water piping to
combustible materials.

so that the chilled medium is piped in parallel
with the heating boiler using appropriate valves
to prevent the chilled medium from entering
the boiler. See Figure 4. Also, consult I=B=R
Installation and Piping Guides.
in air handling units where they may be exposed
to refrigerated air, the boiler piping must be
equipped with flow control valves to prevent
gravity circulation of boiler water during the
operation of the cooling system.

Domestic Hot Water Heater as a separate heating
zone. Refer to the Indirect-Fired Domestic Hot
