Series 2 Gas-fired water boiler — User's Information Manual
GWC
STOP!! — Read before proceeding
User — Have this boiler serviced/inspected by
a qualified service technician, at least annually.
Failure to adhere to the guidelines on this page
can result in severe personal injury, death or
substantial property damage.
Boiler service and maintenance —
• To avoid electric shock, disconnect all electrical supplies
to the boiler before performing maintenance if wiring will
be exposed.
• To avoid severe burns, allow boiler to cool before perform-
ing maintenance.
• You must maintain the boiler as outlined in this manual
and have the boiler started up and serviced at least an-
nually 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.)
• Do not allow contaminated air to enter the boiler room (or
air inlet pipe if direct vented). See page 4 for details.
• Should overheating occur or gas supply fail to shut off, do
not turn off or disconnect electrical supply to boiler. 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.
Should overheating 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.
Combustion air —
•
DO NOT install combustion air intake where there is a
risk of combustion air contamination
If any part of a boiler, burner or its con-
trols has been sprayed with or submerged
under water, either partially or fully, DO
NOT attempt to operate the boiler until the
boiler has been either replaced or com-
pletely 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
substantial property damage. See the instructions
at right.
Part number 550-142-804/1021
Carbon monoxide detector —
• For
required in the boiler room. The carbon monoxide detector
must be wired on the same electrical circuit as the boiler.
• For
wired on the same electrical circuit as the boiler is strongly
recommended.
Boiler water —
• Have boiler water chemistry checked at least annually by a
qualified service technician.
• DO NOT use petroleum-based cleaning or sealing com-
pounds in boiler system. Gaskets and seals in the system may
be damaged. 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.
•
Leaks in boiler or piping must be repaired at once to
prevent make-up water. Use this boiler ONLY in a closed-
loop system.
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 boiler heat exchanger to crack.
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.
,
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.
.
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 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 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 electrical component or
wiring came into contact with water, or was suspected to have
come into contact with water, replace the boiler with a new
Weil-McLain boiler.
