This is accomplished by installing hose bibs as illustrated and allowing water at
city pressure to run into hose bib A, through the heater and out hose bib B until the
discharge is clear. The tees in which the hose bibs are located should be the same
size as heater connections to minimize pressure drop.
d) HARD WATER – May be applicable to some city water and particularly to
well water. Have your water analyzed by a qualified water treatment specialist to
determine if a water softener, conditioner or filtration is required. Treated water will
ensure longer tankless heater life and performance and is also beneficial to all the
piping and fixtures in the building.
4.9 Boil-Out Instructions
4.9.1 Before operating the new Boiler, it should be washed (boiled) out to remove
oil, grease, pipe joint compound, etc. that has accumulated during construction and
installation. This is usually taken care of by the heating contractor. Washing (boil)
out, must not be neglected because impurities may damage the Boiler or cause an
unsatisfactory operating condition.
4.9.2 The following steps are quite general in nature. If a local water treatment
company is going to be part of your boiler maintenance program, they should be
contacted for recommendation as to what boil out chemicals they recommend and
how they will affect their overall treatment program.
1) Remove any foreign materials, which may be left in the Boiler.
2) Check out burner equipment up to, but not including, the actual firing. Refer to
burner manufacturer’s service manual.
3) Remove any controls or accessories that may be damaged by the chemicals used.
4) Remove a plug from a tapping on the highest part of the Boiler. (If no other
opening is available, remove the safety valve carefully to avoid damaging it).
5) Determine the water content of the Boiler, to the applicable level in step
(9) or (10) bellow. This information is provided to you on your respective Boiler’s
record MB drawing in your submittal package, record print package or burner
manufacturer’s service manual.
6) Measure out tri-sodium phosphate at the rate of 1 lb of tri-sodium phosphate
per 50 gallons of boiler water. Mix the chemical with sufficient water to make a
concentrated solution for later pouring into the steam boiler or the hot water boiler
system.
CAUTION!! Use Extreme Care in handling tri-sodium phosphate. It is very Corrosive
and Harmful to skin, eyes and clothing. Use of a face mask, goggles, rubber gloves, and
protective clothing is required. Do Not Permit the dry material or concentrated solution
to come into contact with skin, eyes or clothing.
