DANGER:
▶ The water heater must be installed by a qualified
installer in accordance with these instructions. If
improperly installed, a hazardous condition such as
explosion or carbon monoxide poisoning could
result. Manufacturer is not responsible for
improperly installed appliances.
Common installation practice is to first determine the
venting/combustion air point of termination, then
design the piping layout back to the heater.
NOTICE:
▶ Do not reduce the exhaust or combustion air vent
pipe sizes.
▶ Do not common vent with any other vented appliance
or stove.
DANGER: Flue gas poisoning!
▶ Failure to vent the exhaust gases to the outside with
sealed stainless steel vent pipe (AL29-4C) may
result in dangerous flue gases filling the structure in
which it is installed.
WARNING:
▶ Do not mix vent pipe or joining methods from
different manufacturers.
WARNING:
▶ Approved terminators must be used for inlet and
exhaust vent systems to prevent rain from entering
the appliance. Failure to do so may result in damage
to the appliance. This failure is not covered under the
manufacturer’s warranty.
CAUTION:
▶ The vent system must be installed by a qualified
installer in accordance with these instructions. If
improperly installed, a hazardous condition such as
explosion or carbon monoxide poisoning could
result. Manufacturer will not be responsible for
improperly installed appliances.
