Installation and service must be per formed by a qual i fied service
in stall er, service agency or the gas supplier.
Factory warranty (shipped with unit) does not apply to units
improperly installed or improperly operated.
Experience has shown that improper installation or system design,
rather than faulty equipment, is the cause of most operating
problems.
1. Excessive water hardness causing a lime/scale
build-up in the copper tube is not the fault of the
equipment and is not covered under the
manufacturer’s war ran ty. (See Water Treatment and
Water Chemistry)
2. Excessive pitting and erosion on the inside of the
copper tube may be caused by too much water
velocity through the tubes and is not covered by
the man u fac tur er’s warranty (See Boiler Flow Rates
and Temperature Rise for flow requirements).
This manual supplies information for the installation, operation
and ser vic ing of the appliance. It is strong ly recommended that
