fired water boiler
STOP!! — Read before proceeding
Should overheating of boiler occur or gas supply fail to
shut off, DO NOT
turn off or disconnect electrical supply to circula-
tor. Instead, shut off the gas supply at a location external to the appliance
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 compo-
nents 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.
Boiler service and maintenance —
To avoid electric shock, i n t e r r u p t e l e c t r i c a l
•
supply before performing maintenance.
• To avoid severe burns, allow boiler to cool before per-
forming maintenance.
• You must maintain the boiler as outlined in the manual
and have the boiler started up and serviced at least
annually by a qualified service technician to ensure
boiler/system reliability.
Boiler operation —
• Do not block flow of combustion or ventilation air to boiler.
This boiler is equipped with a control which will automatically
shut down the boiler should air or vent be blocked. If vent or
air blockage is easily accessible and removable, remove it. The
boiler should attempt to restart within an hour. If blockage is
not obvious or cannot be removed, have the boiler and system
checked by a qualified service technician.
Combustion air —
• DO NOT obstruct the combustion air intake or
expose the air intake to corrosive chemicals (see
next page).
Carbon monoxide detector —
•
A carbon monoxide detector that is wired on the
same electrical circuit as the boiler is strongly recommended.
Boiler water —
• Do not use petroleum-based cleaning or sealing compounds
in boiler system. Gaskets and seals in the system may be dam-
aged. This can result in substantial property damage.
• Leaks in boiler or piping must be repaired at once
to prevent make-up water. Use this boiler ONLY in
a closed-loop system. Continual fresh make-up water
will reduce boiler life. Mineral buildup in heat exchangers
reduces heat transfer, overheats the materials, and causes
failure. Addition of oxygen carried in by make-up water can
cause internal corrosion.
• Do not add cold water to hot boiler. Thermal shock can
cause heat exchanger to crack.

– 80/110/150/199 U
Failure to adhere to the guidelines on this page can result in severe personal
injury, death or substantial property damage.

Saltwater Damage
— 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 freshwater (shorting out of electrical compo-
nents, 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 and corrosive
nature of the salt residue. Therefore, Weil-McLain equip-
ment contaminated with saltwater or polluted water will no
longer be covered under warranty and should be replaced.
Electrical Damage
— If any
came into contact with water, or was suspected to have come
into contact with water, do not use this boiler. Immediately call
a qualified service technician to inspect the boiler and to replace
any part of the control system and any gas control that has been
in contact with water.
Water chemistry
Water quality must be maintained as described in boiler manual.
Water pH between 7.0 and 8.5
• Maintain boiler water pH between 7.0 and 8.5. Check with
litmus paper or have chemically analyzed by water treatment
company.
• If pH differs from above, consult local water treatment com-
pany for treatment needed.
Hardness less than 7 grains
Consult local water treatment companies for unusually hard
water areas (above 7 grains hardness).
Chloride concentration must be LESS THAN
50 ppm
• Filling with chlorinated fresh water should be acceptable since
drinking water chloride levels are typically less than 5 ppm.
• Do not use the boiler to directly heat swimming pool or spa
water.
• Do not fill boiler or operate with water containing chloride
in excess of 50 ppm.
Freeze protection fluids —
• NEVER use automotive or standard glycol antifreeze. Use
only freeze-protection fluids made for hydronic systems.
Follow all guidelines given by the antifreeze manufacturer.
Thoroughly clean and flush any replacement boiler system
that has used glycol before installing the new boiler. Use only
the products listed by Weil-McLain for use with this boiler.
See boiler manual for details.
Frozen Water Damage Hazard
Residences or buildings that are unattended in severely cold
weather, boiler system components failures, power outages, 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 action. Consult with your boiler contractor
or a home security agency.
