the boiler with owner or in boiler room, displayed near boiler.
30) After new boiler has been installed and put into continuous operation for several days, clean the boiler of oil, grease,
sludge, and other contaminants that may have been present in existing piping. This will prevent unsteady water line and water
carry over into supply main. The boiler boil-out should be done as follows:
a) Turn off the burner.
b) Drain water from boiler until about one inch of water is visible in gauge glass.
c) Run a hose or temporary piping from the boiler drain valve to a location where hot water can be safely discharged.
Drain approximately five gallons of water from the boiler and mix-in an appropriate amount of an approved boil-out
compound. Remove safety valve and refill the boiler with prepared solution through funnel. Replace safety valve.
d) Run a hose or temporary piping from the 1-1/2” skimmer tap on the upper rear section to a location where hot water
can be safely discharged.
e) Start the burner. Run boiler for several hours, boiling the water, without generating steam pressure. Open the water
feed valve sufficiently to allow a slight overflow of water through the skimmer tapping drain line. Continue boiling
until water coming out is clear.
f) Turn off the burner. Drain hot water from boiler through boiler drain valve to a location where hot water can be
safely discharged. Refill the boiler to normal water line level. If water in the gauge glass does not look clear, repeat
above boil-out procedure again until water clears out.
g) Reinstall safety valve and related piping.
h) Conduct pH and Alkalinity test of water in the system. The pH reading should be in 7 to 11 range.
