Board of Plumbers and Gas Fitters website, http://license.reg.state.ma.us/pubLic/pl_products/pb_pre_form.asp for the latest
Approval Code or ask your local Sales Representative.
The Commonwealth of Massachusetts requires this product to be installed by a Licensed Plumber or Gas Fitter.
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 qualied 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 signicantly 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 included with this boiler.
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.
