Un spécialiste qualifié en chimie du traitement de
l'eau doit être consulté pour des recommandations
concernant les composés chimiques appropriés et les
concentrations compatibles avec les réglementations
Chemicals used in treating boiler water are toxic and/or
harmful. Always use protective clothing and equipment
when working with/near chemicals. Contact local
authorities to determine if treated boiler water can be
discharged into local waste water system.

1. Oil, greases & sediments which accumulate in a
new boiler and piping must be removed in order
to prevent an unsteady water line and carry over
of the water into the supply main above boiler.
Operate the boiler with steam in the entire system
for a few days allowing the condensate to return
to the boiler. If the condensate can temporarily be
wasted, operate boiler only for the length of time it
takes for condensate to run clear. If the latter cannot
be achieved or if the condensate is returned to the
boiler, boil out the boiler using the SURFACE
BLOWOFF connection. See Figure 43.
a. Drain boiler until water is just visible in gauge
glass. Run temporarily 1½″ pipe line from the
surface blowoff connection to an open drain or
some other location where hot water may be
discharged safely. Do not install valve in this
line.
b. Add an appropriate amount of recommended
boilout compounds.
c. Start burner and operate sufficiently to boil
the water without producing steam pressure.
Boil for about 5 hours. Open boiler feed pipe
sufficiently to permit a steady trickle of water
from the surface blowoff pipe. Continue this
slow boiling and trickle of overflow for several
hours until the water coming from the overflow
is clear.
d. Stop burner and drain boiler in a manner and to
a location that hot water can be discharged with
safety.
e. Refill boiler to normal water line. If water in
gauge glass does not appear to be clear, repeat
steps (a. thru e.), and boil out the boiler for a
longer time.
2. Low pressure steam boilers such as the V11H
Series should be maintained with appropriate
water treatment compounds. Add water treatment
compounds as recommended by your local qualified
water treatment company.
3. Remove temporary surface blowoff piping, plug
tapping and reinstall safety valve. Boil or bring
water temperature to 180°F promptly in order to
drive off the dissolved gases in the fresh water.
4. If unsteady water line, foaming or priming persist,
install gate valve in Hartford Loop and drain valves
in return main and at boiler and proceed as follows:
a. Connect hoses from drain valves to floor drain.
Close gate valve in Hartford Loop and open
drain valve in return main. Fill boiler to normal
water level, turn on burner and operate boiler
at this water level for at least 30 minutes after
the condensate begins to run hot, then turn off
burner.
Close all radiator valves. Remove all supply
main air valves and plug the openings in supply
main.
b. Draw about 5 gallons of hot water from boiler
into a container and dissolve into it appropriate
amount of a recommended boilout compound.
Remove safety valve and pour this solution into
boiler, then reinstall safety valve.
c. Turn on burner and keep operating while feeding
water to boiler slowly. This will raise water level
in boiler slowly so that water will be boiling hot
and will rise slowly into supply main and back
through return main, flowing from drain hose
at about 180°F. Continue until water runs clear
from drain hose for at least 30 minutes.
d. Stop feeding water to boiler but continue
operating burner until excess water in boiler
flows out through supply main and water lowers
(by steaming) until it reaches normal level in
boiler. Turn off burner. Drain boiler. Open all
radiator valves. Reinstall all supply main air
valves. Open gate valve in Hartford Loop.
e. When boiler has cooled down sufficiently (crown
sheet of sections are not too hot to touch), close
the drain valves at boiler and in return main and
feed water slowly up to normal level in boiler.
Turn on burner and allow boiler to steam for
10 minutes then turn off burner. Draw off one
quart of water from bottom gauge glass fitting
and discard. Draw off another quart sample and
if this sample is not clear, repeat the cycle of
draining the boiler and return main and refilling
the boiler until sample is clear.
f. If the boiler water becomes dirty again at a later
date due to additional sediment loosened up in
the piping, close gate valve in Hartford Loop,
