Water Chemistry Requirements - FULTON VMP-W 40 -150 HP Installation And Operation Manual

SECTION 2
VMPW-IOM-2012-1001
5. Pipe the water safety valve carry piping from the outlet of the valve to a
safe blow-o point.
NOTE: Do not alter water temperature/pressure gauge assembly in any way.
6. Drain valve is connected to the lowest opening at bottom rear of boiler.
Carry piping from the outlet of the valve to safe drain point. Provision
should be made for easy access to drain valve of boiler.
NOTE: The water connection on the top of the boiler is the outlet connection. The
water connection on the rear of the boiler is the inlet connection.
7. Install ltration to remove particulates if appropriate.
8. Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.
9. Install corrosion coupon holder to assess corrosion inhibitor performance if
appropriate.
NOTE: The boiler is provided with a drain valve connection and a drain valve.
10. Heating system:
» An automatic pressure activated water make up valve with back
ow preventer. It must be set to maintain required Net Positive
Suction Head (NPSH) for re-circulating pumps, a positive system
pressure at the highest point of at least 5-10 PSIG, and make up
water valve should be designed to add water to the system at the
outlet of the boiler and should not be fed directly into the boiler.
» Air removal equipment, including an air separator and automatic
breather valves, along with a functioning expansion tank . Each
must be designed to system speci cations.
11. When used in conjunction with a refrigeration system, install the boiler
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 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
