15. Fill boiler to normal water line. Follow Operating
Instructions to place boiler in operation. See Figure
21.
16. Operate boiler for at least 30 minutes after
condensate begins to run hot. Follow instructions
TO TURN OFF GAS TO APPLIANCE. See Figure
21.
17. Close all radiator valves. Remove all supply main
air valves. Plug openings in supply main.
18. Drain approximately 5 gallons of boiler water into
container. Mix in recommended boil-out
compound.
19. Remove safety valve. Pour recommended compound
into boiler through safety valve opening. Reinstall
safety valve in Tapping "E" with spindle in vertical
position.
20. Follow Operating Instructions to place boiler in
operation. See Figure 21. 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.
21. 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.
22. Follow instructions TO TURN OFF GAS TO
APPLIANCE. See Figure 21. Open all radiator
valves. Reinstall all supply main air valves. Open
gate valve in Hartford Loop.
23. 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.
24. Follow Operating Instructions to place boiler in
operation. See Figure 21. Allow boiler to steam for
10 minutes. Drain one quart of water from lower
Gauge Glass fitting.
25. Drain second quart sample from lower Gauge Glass
fitting. If sample is not clear, repeat cycle of draining
boiler and return main and refilling boiler until
sample is clear.
26. If after normal operation boiler water becomes dirty
from additional system piping sediment returning to
boiler.
a. Complete steps 12 through 25.
b. Complete steps 1 through 11.
P.
Add Boiler Water Treatment
1. Remove safety valve.
2. Pour recommended compound into boiler through
safety valve opening.
3. Reinstall safety valve in Tapping "E" with spindle in
vertical position.
4. Follow Operating Instructions to place boiler in
operation. See Figure 21.
5. Boil water or heat water to 180°F.
6. Test the pH of the water in the system. This can
easily be done by drawing a small sample of boiler
water and testing with Hydrion paper which is used
in the same manner as litmus paper, except it gives
specific readings. A color chart on the side of the
small Hydrion dispenser gives the reading in pH.
Hydrion paper is inexpensive and obtainable from
any chemical supply house or through your local
druggist. The pH should be higher than 7 but lower
than 11. Add recommended water treatment
chemicals, if necessary, to bring the pH within the
specified range. With this lower level of protection,
care must be exercised to eliminate all of the free
oxygen in the system.
7. Boiler is now ready to be put into service.
