The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on
of this manual. Failure to comply could result in severe personal injury.
When calling or writing about the boiler— Please have the boiler model number from the boiler rating label and the
CP number from the boiler jacket. You may list the CP number in the space provided on the
certificate
found on page 36.
Failure to adhere to the guidelines on this page can result in severe personal injury, death or substantial
property damage.
When servicing boiler —
•
To avoid electric shock, disconnect electrical supply before
performing maintenance.
•
To avoid severe burns, allow boiler to cool before perform-
ing maintenance.
Boiler operation —
•
Do not block flow of combustion or ventilation air to boiler.
•
Should overheating occur or gas supply fail to shut off, do
not turn off or disconnect electrical supply to circulator.
Instead, shut off the gas supply at a location external to the
appliance.
•
Do not use this boiler if any part has been under water.
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 under water.
Boiler water —
•
Do not use petroleum‑based cleaning or sealing com-
pounds in boiler system. Water seal deterioration will
occur, causing leakage between sections. This can result
in substantial property damage.
•
Do not use"homemade cures"or"boiler patent medicines".
Serious damage to boiler, personnel and/or property may
result.
•
Continual fresh makeup water will reduce boiler life. Min-
eral buildup in sections reduces heat transfer, overheats cast
iron, and causes section failure. Addition of oxygen and
other gases can cause internal corrosion. Leaks in boiler or
piping must be repaired at once to prevent makeup water.
•
Do not add cold water to hot boiler. Thermal shock can
cause sections to crack.
Glycol — potential fire hazard —
All glycol is flammable when exposed to high temperatures. If
glycol is allowed to accumulate in or around the boiler or any

other potential ignition source, a fire can develop. In order to
prevent potential severe personal injury, death or substantial
property damage from fire and/or structural damage:
•
Never store glycol of any kind near the boiler or any po-
tential ignition source.
•
Monitor and inspect the system and boiler regularly for
leakage. Repair any leaks immediately to prevent possible
accumulation of glycol.
•
Never use automotive antifreeze or ethylene glycol in the
system. Using these glycols can lead to hazardous leakage
of glycol in the boiler system.

Saltwater Damage
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 components,
washing out of critical lubricants, etc.), the salt and other con-
taminants 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 equipment contaminated
with saltwater or polluted water will no longer be covered under
warranty and should be replaced.
Electrical Damage —
If any

come into contact with water, replace the boiler with a new
Weil‑McLain boiler.
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 tem-
perature, and initiates an effective action. Consult with your
boiler contractor or a home security agency.
