"OILEROPERATION
s Do not block flow of combustion or
ventilation air to boiler.
s Should overheating occur or gas sup-
ply fail to shut off, do not turn off or
disconnect electrical supply to pump.
Instead, shut off the gas supply at a
location external to the appliance.

s Thoroughly flush the system (without
boiler connected) to remove sedi-

ment removal equipment if necessary.
The high-efficiency heat exchanger
can be damaged by build-up or cor-
rosion due to sediment.

Frozen Water Damage

tended in severely cold weather, boiler
system components failures, power out-
ages, or other electrical system failures
could result in frozen plumbing and water
damage in a matter of hours. For your
protection,take preventative actions such
as having a security system installed that
operates during power outages,senses low
temperature, and initiates an effective ac-
tion. Consult with your boiler contractor
or a home security agency.
If any part of a boiler, burner or its controls has
been sprayed with or submerged under water,
either partially or fully, DO NOT attempt to op-
erate the boiler until the boiler has been either
replaced or completely repaired, inspected, and
you are sure that the boiler and all components
are in good condition and fully reliable.
Otherwise, by operating this boiler, you will cause
a fire or explosion hazard, and an electrical shock
hazard,leading to serious injury, death,or substan-
tial property damage. See the instructions at right.
3ALTWATER $AMAGE — The exposure of boiler components to
saltwater can have both immediate and long-term effects.While the
immediate effects of saltwater damage are similar to those of fresh-
water (shorting out of electrical components, washing out of critical
lubricants, etc.),the salt and other contaminants left behind can lead
to longer term issues after the water is gone due to the conductive
