Safe Boiler Operation

• Do not block flow of combustion or ventilation
air to boiler This boiler is equipped with a control
that automatically shuts down the boiler if the air
or vent is blocked Remove easily accessible and
2
removable blockages If the boiler indicates a
manual reset lockout, select <Reset Lockout> on
the control display after removing a blockage If
a blockage cannot be removed, have a qualified
service technician check the boiler system
• Do not allow contaminated air to enter the boiler room,
3
or the air inlet pipe if direct vented See page 5 for
details
• Should overheating occur, or gas supply fail to
shut off, do not turn off or disconnect electrical
supply to pump. Shut off the gas supply at a
location external to the appliance
4

Boiler Water

• Have the boiler water chemistry checked at least
annually by a qualified service technician.
• Do not use petroleum-based cleaning or sealing
compounds in the boiler system Gaskets and seals
5
in the system may be damaged, which can result in
substantial property damage
• Do not use "homemade cures" or "boiler patent
medicines " Serious injury or damage may result
• Continual fresh make-up water will reduce boiler
life Mineral buildup in the heat exchanger reduces
6
heat transfer, overheats the metal, and causes
failure Addition of oxygen carried in by make-up
water can cause internal corrosion Leaks in the
boiler or piping must be repaired at once to prevent
make-up water
• Do not add cold water to a hot boiler Thermal
shock can cause the heat exchanger to crack
7
• NEVER use automotive or standard glycol
antifreeze inn this boiler system, including glycol
made for hydronic systems

Frozen Water Damage

Power outages, unattended residences or buildings,
boiler component failures, or other electrical system
failures in cold weather could result in frozen plumbing
and water damage in a matter of hours Consult with
a boiler contractor or a home security agent to take
preventative actions, such as installing a security
system that operates during power outages, senses
low temperature, and initiates an effective action.
Consult with your boiler contractor or a home security
agency

Damage from Water Contact

DANGER
!
DO NOT attempt to operate any boiler if any
part of the boiler, burner, or controls has been
partially or fully sprayed with or submerged
under water. The boiler must either be replaced
or completely repaired and inspected. The boiler
and all components must be in good condition
and fully reliable before operation.
If these requirements are not met, operating
the boiler will cause fire, explosion, and electrical
shock hazards, leading to serious injury, death,
or substantial property damage.
Saltwater damage: The immediate effects of
saltwater damage are like those of freshwater,
with electrical components shorting out and the
removal of critical lubricants However, salt and other
contaminants left behind can lead to long term issues
due to the conductive and corrosive nature of salt
residue WM Technologies 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 has, or is suspected to have come into contact
with water, replace the boiler
