Safety Information 5
The following safety symbols are used in this manual. Read and
follow all safety instructions in this manual precisely to avoid
unsafe operating conditions, fire, explosion, property damage,
personal injury, or death.
DANGER
Indicates an imminently hazardous situation which, if not
avoided, could result in severe injury or death.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, could result in injury or death.
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, could result in property damage.
DANGER
If you smell gas:
●Do not try to light any appliance.
●Do not touch any electrical switches or use landline
phones.
●From a neighbor’s phone, call your gas provider and
follow their instructions.
●If you cannot reach your gas provider, call the fire
department.
●Do not return to your home until authorized by your gas
supplier or the fire department.
Do not use or store flammable products, such as
gasoline, solvents, or adhesives in the same room or
area as the boiler.
●The boiler has a main burner flame that can turn on at
any time and can ignite flammable vapors. Vapors from
flammable liquids can explode and catch fire, causing
death or severe burns.
●Vapors cannot be seen and are heavier than air. They can
travel long distances along the ground and can be carried
from other rooms to the boiler’s main burner flame by air
current.
●Keep all flammable products far away from the boiler and
store them in approved containers. Keep the containers
closed tightly and out of the reach of children and pets.

6 Safety Information
CAUTION
●Do not turn on the boiler unless the water and gas
supplies are fully opened.
Doing so may damage the boiler.
●Do not turn on the water if the cold water supply shut-
off valve is closed.
Doing so may damage the boiler.
●Do not use this boiler for anything other than its
intended purpose, as described in this manual.
●Do not remove the front cover unless the power to the
boiler is turned off or disconnected.
Failure to do so may result in electric shock.
●When servicing the controls, label all wires prior to
disconnecting them.
Failure to do so may result in wiring errors, which can
lead to improper or dangerous operation. Verify proper
operation after servicing.
●Do not use unapproved replacement or accessory
parts.
Doing so may result in improper or dangerous operation
and will void the manufacturer’s warranty.
●Do not place anything in or around the vent terminals,
such as a clothes line, that could obstruct the air flow
in or out of the boiler.
●This boiler has been approved for use in the USA and
Canada only.
Using the boiler in any other country will void the
manufacturer’s warranty.
WARNING
●Do not store or use gasoline or other flammable
liquids near this boiler.
Doing so may result in fire or explosion.
●Do not place combustibles, such as newspapers or
laundry, near the boiler or venting system.
Doing so may result in a fire.
●Do not place or use hair sprays, spray paints, or any
other compressed gases near the boiler or venting
system, including the vent termination.
Doing so may result in fire or explosion.
●Do not operate the boiler with the front cover opened.
Doing so may result in fire or carbon monoxide (CO)
poisoning, which may result in property damage, personal
injury, or death.
●Do not operate this boiler without proper venting.
Doing so may result in fire or carbon monoxide (CO)
poisoning, which may result in property damage, personal
injury, or death.
●Do not touch the power cord or internal components
of the boiler with wet hands.
Doing so may result in electric shock.

Safety Information 7
DANGER
This boiler’s water temperature is set to 49°C at the factory
for your safety and comfort. Increasing the temperature
increases the risk of accidental scalding. Water temperatures
at or above 52°C can cause instant scalding, severe burns, or
death. Before you decide to change the temperature setting,
read the following charts carefully.
Water
Temperature
Time in which a young child can suffer a
full thickness (3rd degree) burn
70°C Less than 1 second
60°C 1 second
55°C 10 seconds
49°C 10 minutes
37°C very low scald risk
DANGER
HOT
BURN
To prevent burns:
●Use the lowest operating temperature setting necessary
to provide comfortably-hot water.
●If your household has children or elderly or disabled
residents, consider using a lower temperature setting.
●Read all the instructions in this manual carefully before
changing the temperature setting.
●Feel the water before using it on children, the elderly, or
the disabled.
