operation up to 4,500 feet with no field adjustments.
Output ratings will be reduced by 4% for each 1,000
feet above sea level up to 4,500 feet only.
3.
High altitude Armor water heaters will have a high
altitude label affixed to the unit (as shown in FIG. A)
and are equipped for operation of 4,501 feet to
12,000 feet only with no field adjustments. For high
altitude models, output ratings will be reduced by 2%
