High Altitude Installations

Fire and Explosion Hazard

Under no circumstances should the input exceed the rate shown on the water heater’s rating label.

Overfiring could result in fire or explosion.

Gas and carbon monoxide detectors are available.

Breathing Hazard - Carbon Monoxide Gas

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.

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 feet (610 m). Do not install these water heater models above 2,000 feet (610 m) elevation.
