The following terms are used throughout this manual to bring attention to the presence of hazards of various risk
levels, or to important information concerning product life.
DANGER
Indicates an imminently hazardous situation
which, if not avoided, will result in death, serious
injury or substantial property damage.
CAUTION
Indicates a potentially hazardous situation which,
if not avoided, may result in moderate or minor
injury or property damage.
WARNING
Indicates a potentially hazardous situation which,
if not avoided, could result in death, serious injury
or substantial property damage.
NOTICE
Indicates special instructions on installation,
operation, or maintenance which are important
but not related to personal injury hazards.
CAUTION
If, during normal operation, it is necessary to add water to this boiler more frequently than once a month,
consult a qualied service technician to check your system for leaks. A leaky system will increase the volume
of make-up water supplied to the boiler which can signicantly shorten the life of the boiler. Entrained in
make-up water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the boiler
the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler life. The
accumulation of sediment can eventually isolate the water from contacting the cast iron. When this happens
the cast iron in that area gets extremely hot and may eventually crack. The presence of free oxygen in the
boiler creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode the cast
iron through from the inside. Since neither of these failure types are a result of a casting defect the warranty
does not apply. Clearly, it is in everyone's best interest to prevent this type of failure. The maintenance of
system integrity is the best method to achieve this.
NOTICE
This boiler has a limited warranty, a copy of which is printed on the back of this manual.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is complete.
Surface rust on cast iron sections may be attributed to the manufacturing process as well as condensation
during storage. Surface rust is normal and does not affect the performance or longevity of a boiler.
