will be reduced. A larger steam
valve (and possible a larger steam
line) may be required. If these
conditions are suspected, and are
preventing proper operation of your
heater, please consult the factory.
6. Install dielectric unions at all
connections between the Pick
heater and copper piping. For the
most part, standard Pick water
heaters are constructed from iron
housings and steel pipe. Directly
connecting iron or steel components
to copper piping will result in rapid
corrosion of the iron or steel, also
known as galvanic corrosion.
7. Bleeding air from water lines.
Note that water releases dissolved
air when heated. The water velocity
is normally not high enough to flush
air out of the distribution header if
take off points exit the bottom or
side of the water header.
8. All distribution branches should
connect tot eh top of the header,
or automatic air vent valve(s) should
be installed at the high points of the
header. Correct the condition as
necessary.
9. Unstable water pressure can cause
system vibration and hammer
problems. Heavy demands on the
cold water supply can cause
significant changes in the supply
pressure to the heater. A water
pressure regulating valve may be
required to stabilize the water
supply pressure.
10. Use-point valves closing too fast
can cause hydraulic shock and a
system upset.
IMPORTANT: An incorrectly installed
heater will not work properly. Check
heater installation carefully; correct
piping connections as appropriate.
