SERIES 4 — GAS-FIRED WATER BOILER —
Please read before proceeding
Installer
Read all instructions before installing.
Follow all instructions in proper order to prevent
personal injury or death.
•
Consider piping and installation when determining boiler
location.
Any claims for damage or shortage in shipment must
•
be filed immediately against the transportation company
by the consignee.
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 Consumer Protection (CP) number from the boiler jacket. You may list the CP number in the space provided
on the Installation and service certificate found on page 36.
The installer must verify that at least one carbon monoxide alarm has been installed within a residential living space
or home following the alarm manufacturer's instructions and applicable local codes before putting the appliance into
operation. Failure to adhere can result in severe personal injury, death or substantial property damage.
Failure to adhere to the guidelines on this page can result in severe personal injury, death or sub-
stantial property damage.
When servicing boiler —
•
To avoid electric shock, disconnect electrical supply
before performing maintenance.
•
To avoid severe burns, allow boiler to cool before
performing 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 wa-
ter. 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 medi-
cines". Serious damage to boiler, personnel and/or
property may result.
•
Continual fresh makeup water will reduce boiler life.
Mineral buildup in sections reduces heat transfer,
overheats cast iron, and causes section failure. Ad-
dition 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 tempera-
tures. 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
potential 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
nents 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 contaminants left behind can lead to longer
term issues after the water is gone due to the conduc-
tive 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 —
came into contact with water, or was suspected
wiring
to have 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 temperature, and initiates an
effective action. Consult with your boiler contractor or a
home security agency.
