AS FIRED WATER BOILER

Please read before proceeding

— Read all instructions, including this manual
and all other information shipped with the boiler,
before installing. Perform steps in the order given.
— This manual is for use only by a qualified
heating installer/service technician. Refer to User's
Information Manual for your reference.
— Have this boiler serviced/inspected by a qualified
service technician, at least annually.
Failure to comply with the above could result in severe
personal injury, death or substantial property damage.
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 operate
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
substantial property damage. See the instructions
at right.
Failure to adhere to the guidelines below can result in severe personal injury, death or substantial property damage.
Relieve pressure from the system
before isolating the expansion tank.
To avoid electric shock, disconnect all
electrical supplies to the boiler before
performing maintenance.
To avoid severe burns, allow boiler to cool
before performing maintenance.
This boiler contains ceramic fiber
and fiberglass materials. Refer to the
WARNING and instructions on page 106.
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 install combustion air intake
where there is a risk of combustion air
contamination.
A carbon monoxide detector that is
wired on the same electrical circuit as
the boiler is strongly recommended.

Provide surge protection in the boiler
power supply. This will reduce the
possibility of damage to the boiler
control.
The heat exchanger is made of
ECO Tec
stainless steel, and requires that system
water chemistry be within the limits in
this manual.
page 97 for details.
Thoroughly flush the system (
connecting boiler) to remove sediment.
The high-efficiency heat exchanger can
be damaged by build-up or corrosion
due to sediment.
Do not use petroleum-based cleaning
or sealing compounds in boiler system.
Gaskets and seals in the system may be
damaged. This can result in substantial
property damage.
Continual fresh make-up water will
reduce boiler life. Mineral buildup in
eat exchanger reduces heat transfer,
overheats the stainless steel heat
exchanger, and causes failure. Addition
of oxygen carried in by make-up water
can cause internal corrosion. Leaks in
boiler or piping must be repaired at once
When the boiler is installed within the Commonwealth of Massachusetts:
This product must be installed by a licensed plumber or gas fitter.
If antifreeze is used, a reduced pressure back-flow preventer device shall be used.
Sidewall vent air installations — see instruction on page 24.

Write in the Consumer Protection (CP) number in the
space provided on the Installation certificate on page 151
if not already shown.
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.
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 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.
— If any
into contact with water, or was suspected to have come into contact
with water, replace the boiler with a new Weil-McLain boiler.
to prevent make-up water. Use this boiler
ONLY in a closed-loop system.
Do not add cold water to a hot boiler.
Thermal shock can cause the heat
exchanger to crack.
NEVER use automotive or standard
glycol antifreeze. Use only freeze-
protection fluids made for hydronic
systems. Follow all guidelines given by
. See
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 page 98 for details.
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.
