High Altitude Installations - American Water Heater BCL380T1996NOX Instruction Manual

Some circulating pumps are manufactured with sealed
bearings and do not require further lubrication. Some
circulating pumps must be periodically oiled. refer to
the pump manufacturer's
requirements.

Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
The water heaters covered by this manual are certified for use
without modification for altitudes up to 2,000' (609 m). For 2001' to
10,000' high altitude installations, order special High Altitude Models.
As elevation above sea level is increased, there is less oxygen
per cubic foot of air. Therefore, factory installed equipment is
required for satisfactory operation at high altitudes above 2,000'
(609m). Failure to install high altitude model would result in an
over firing of the heater causing sooting, poor combustion and/or
unsatisfactory heater performance.
