HIGH ALTITUDE INSTALLATIONS FOR ELEVATIONS OVER 2,000 FEET (762 m)
ABOVE SEA LEVEL
The capacity of the induced draft blower declines with increasing altitude due to a
reduction in the air density. In order to assure safe and reliable performance of the water
heater, contact the supplier for a high-altitude kit.
