f. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57. Check controls operation per
Paragraphs F to J. Boil water for at least 5 hours.
g. Follow instructions TO TURN OFF GAS TO
APPLIANCE. See Figure 53, 54, 55, 56 or 57.
Drain boiler and system piping.
h. Remove drain valve. Thoroughly wash boiler
water passages with high pressure spray through
drain valve tapping.
i. Reinstall drain valve in Tapping "F". See
Figures 1 and 2.
3. Second Boil-out for Stubborn Cases. If all oil and
grease is not removed a second boilout using surface
blow-off is necessary.
a. Run 1 NPT pipe from Surface Blow-Off Tapping
"L" to open drain. Do not install shut-off valve or
other restriction. See Figure 2.
b. Fill boiler to top of gauge glass.
c. Remove safety valve.
d. Pour recommended boil-out compound into
boiler through safety valve opening.
e. Reinstall safety valve in Tapping "E" with
spindle in vertical position. See Figures 1 and 2.
f. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57. Boil water for approximately 5 hours
without producing steam.
g. Open boiler fill shut-off valve to produce steady
trickle of water from surface blow-off pipe.
Continue boil-out for several hours until surface
blow-off water runs clear.
h. Follow instructions TO TURN OFF GAS TO
APPLIANCE. See Figure 53, 54, 55, 56 or 57.
Drain boiler and system piping.
i. Remove drain valve. Thoroughly wash boiler
water passages with high pressure spray through
drain valve tapping.
j. Fill boiler to normal waterline. If water in gauge
glass is not clear, repeat procedure starting at
step b.
k. Remove surface blow-off piping. Install 1 NPT
plug in Tapping "L". See Figure 2.
4. Add Boiler Water Treatment.
a. Remove safety valve.
b. Pour recommended compound into boiler
through safety valve opening.
c. Reinstall safety valve in Tapping "E" with
spindle in vertical position. See Figures 1 and 2.
d. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57.
e. Boil water or heat water to 180°F.
f. Measure boiler water alkalinity. pH should be
between 7 and 11. Add recommended water
treatment chemicals, if necessary, to bring the pH
within the specified range.
5. If unsteady water line, foaming or priming persist:
a. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57.
b. Install gate valve (shut-off valve) in Hartford
Loop. Install drain valves in return main and at
boiler. See Figure 23.
c. Connect hoses from drain valves to floor drain.
Close gate valve in Hartford Loop. Open drain
valve in return main.
d. Fill boiler to normal water line. Follow Lighting
or Operating Instructions to place boiler in
operation. See Figure 53, 54, 55, 56 or 57.
e. Operate boiler for at least 30 minutes after
condensate begins to run hot. Follow instructions
TO TURN OFF GAS TO APPLIANCE. See
Figure 53, 54, 55, 56 or 57.
f. Close all radiator valves. Remove all supply
main air valves. Plug openings in supply main.
g. Drain approximately 5 gallons of boiler water
into container. Mix in recommended boil-out
compound.
h. Remove safety valve. Pour recommended
compound into boiler through safety valve
opening. Reinstall safety valve in Tapping "E"
with spindle in vertical position. See Figures 1
and 2.
i. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57. Slowly feed water to boiler. Water will
rise slowly into supply main and back through
return main. Adjust flow to maintain
approximately 180°F water from return main
hose. Continue until water runs clear from hose
for at least 30 minutes.
j. Turn off water to boiler. Continue to operate until
excess water is removed from boiler and system
(by steaming) and boiler water reaches normal
waterline.
k. Follow instructions TO TURN OFF GAS TO
APPLIANCE. See Figure 53, 54, 55, 56 or 57.
Open all radiator valves. Reinstall all supply
main air valves. Open gate valve in Hartford
Loop.
l. Allow boiler to cool until crown sheet is no
longer too hot to touch. Close drain valves at
boiler and in return main. Fill boiler slowly to
normal waterline.
m. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57. Allow boiler to steam for 10 minutes.
Drain one quart of water from lower Gauge
Glass fitting.
