HIGH ALTITUDE INSTALLATIONS
Fire and Explosion Hazard
Gas and carbon monoxide detectors are
available.
Overfiring could result in fire or
explosion.
Under no circumstances should the
input exceed the rate shown on the
water heater’s rating label.
Breathing Hazard - Carbon Monoxide Gas
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Under no circumstances should
the input exceed the rate shown
on the water heater’s rating label.
Overfiring could result in damage to
the water heater and sooting.
Gas and carbon monoxide detectors
are available.
The water heaters covered by this manual are certified for
use without modification for altitudes up to 10,100 feet.
Most gas utility companies de-rate their gas for high
altitudes, making it unnecessary to install high altitude
orifices.
For installations above 10,100 feet call the technical
support phone number listed on the back cover of this
manual for further technical assistance. Call the local
gas or utility company to verify Btu per cubic foot content
before calling for technical assistance and have that
information available.
NOTE: The actual firing rate of the water heater must not
exceed the input rating on the water heater's rating label
under any circumstances.
NOTE: Due to the input rating reduction at high altitudes,
the output rating of the water heater is also reduced and
should be compensated for in the sizing of the equipment.
