FOLLOW ALL INSTRUCTIONS and warnings
printed in this manual and posted on the boiler.
INSPECT THE BOILER ANNUALLY. To keep
your boiler safe and efficient, have a service
technician follow the Service checklist near the
end of this manual.
IF YOU ARE NOT QUALIFIED to install or service
boilers, do not install or service this one.
THE BOILER MAY LEAK WATER at the end of its
useful life. Be sure to protect walls, carpets, and
valuables from water that could leak from the
boiler.
PROTECT YOUR HOME IN FREEZING
WEATHER. A power outage, safety lockout, or
component failure will prevent your boiler from
lighting. In winter, your pipes may freeze and
cause extensive property damage. Do not leave
the heating system unattended during cold
weather unless alarms or other safeguards are in
place to prevent such damage
WARNINGS FOR THE HOMEOWNER
DO NOT BLOCK AIR FLOW into or around the
boiler. Insufficient air may cause the boiler to
produce carbon monoxide or start a fire.
KEEP FLAMMABLE LIQUIDS AWAY from the
boiler, including paint, solvents, and gasoline.
The boiler may ignite the vapors from the liquids
causing explosion or fire.
KEEP CHILDREN AND PETS away from hot
surfaces of the boiler, boiler piping, vent piping
and vent terminals.
CARBON MONOXIDE (CO) is an odorless,
deadly gas that may be introduced into your
home by any malfunctioning fuel-burning
product or vent system failure. Consider
installing CO alarms near bedrooms in all levels
of the building to warn you and your family of
potential CO exposure.
