IV. Water Trim and Piping
A.
Design and install boiler and system piping
to 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
must 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.
f. Use properly designed and operating air
elimination devices in water piping.
B
. Design system to obtain a 20°F temperature rise through
the boiler (see Table 4). If a temperature rise greater
than 40°F is desired, consult Burnham.
C.
Install Safety Relief Valve
. See Figure 20. Components
are located in Water Trim Carton. Safety Relief Valve
must be installed with spindle in vertical position.
1. Install ¾" NPT x 3½" lg. nipple in tapping "C". See
Figure 3.
