DIRECTIONS FOR USE
Shake well before using. Drain off a container of water after opening
boiler drain. Look at contents of container to determine which of the
following treatments is required:
Annual Treatment or Moderately Dirty Systems:
No flushing is needed. Close off all valving between boiler and zon-
ing circuits. Drain off a sufficient quantity of water to allow space for
the product. Lower the boiler pressure. Pour proper amount (See
Quantity Table) through any convenient opening when pressure in
boiler subsides. Reclose addition point and reopen circuit valving.
Let product remain in boiler for entire season. Check boiler drain-off
valve for removal of sludge or scale.
Oily, Surging or Rusty Systems:
1) Turn off heating unit. Close off zoning as described above. Pour
first dose (See Quantity Table) into top opening (valve or plug). Fill
with water to operating level. Replace valve or plug on top of boiler
with an elbow with a piece of rubber hose attached. Place end of
hose in metal receptacle. 2) Fire boiler and raise water level until
steam and/or water flush oil and floating contaminants away through
hose. When water runs clear, shut off water and heat source and
remove hose. BE CAREFUL OF ESCAPING HOT WATER AND
STEAM. 3) Drain boiler water, if necessary, to operating level. Add
second dose of boiler & heating system cleaner. Replace elbow
and hose with original valve or plug. Reopen circuit valving. Fire
boiler to normal pressure and allow to operate one week. 4) After a
week, cut off heat and let boiler cool; open bottom drain-off valve and
drain to remove heavy sediment. 5) Clean all drain-cocks, gauges,
gauge glasses, valves and replace. 6) Refill boiler. Add another dose
of boiler & heating system cleaner and allow to remain in boiler.
Dirty Hot Water Heating Boilers and Systems:
1) Turn off heat, drain boiler and entire system. Open all air vents.
Pour boiler & heating system cleaner (See Quantity Table) into
boiler through suitable opening. Remove relief valve if necessary.
2) Replace relief valve, close vents, fill system with water. Vent each
radiator until all air is removed from system. 3) Fire system and oper-
ate for at least one hour. 4) Cut off heat, let boiler cool. Drain sedi-
ment. Vent radiator. Refill with water if needed. 5) Operate system. (If
