HIGH ALTITUDE INSTALLATIONSFOR ELEVATIONS OVER 3,000 FEET (914.5 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, the following guidelines must be followed. Refer to the venting tables below for maximum distances for the altitudes in your location.
