so that the chilled medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium from entering
the boiler. If the boilers are connected to heating coils (located in air
handling units where they may be exposed to refrigerated air circulation)
such boiler piping systems must be equipped with fl ow control valves or
other automatic means to prevent gravity circulation of the boiler water
during the cooling cycle.
Water Chemistry Requirements
System water chemistry requirements are as follows:
pH: Range of 8.5 - 10.5
Oxygen: Less than 250 ppb (operating condition)
Total Iron/Copper: Less than 5 ppm
Corrosion Inhibitor: Capable of maintaining iron corrosion rates <2
mpy. Due to changing environmental restrictions a non-heavy metal
ALL ORGANIC inhibitor is recommended which is designed for multi
metal systems including ferrous metals and yellow metals such as
copper and brass.
Chloride: Less than 250 ppm
Adhere to the following:
1. Refer to your water conditioning or chemical treatment supplier for
analysis and recommendations for proper system conditions.
2. Follow a program with appropriate monitoring and maintenance of
system water conditions as provided by your water conditioning or
chemical treatment supplier.
3. Operate the boiler in a closed-loop system using water or water/glycol
(not requiring a make-up water supply). A large amount of improperly
treated make-up water can cause premature failure of the heat
exchanger resulting from scale build up. Scale build up will reduce the
effi
ciency and useful life of the boiler and is not covered under warranty.
Prevent Oxygen Contamination
There are several ways to prevent boiler water oxygen contamination:
Minimize system leaks to minimize make up water requirement
Do not use open tanks or fi ttings
Do not use oxygen permeable materials anywhere in the water
system
Repair leaks in the system quickly
Eliminate fi ttings wherever possible

CAUTION
A large amount of improperly treated make-
up water can cause premature failure of the
heat exchanger resulting from scale build
up. Scale build up will reduce the effi
ciency
and useful life of the boiler and is not
