Notes:

1. Armor water heaters require special gas venting. Use only the vent materials and methods specified in the Armor Installation and Operation Manual.

2. Standard Armor water heaters are equipped to operate from sea level to 4,500 feet only with no adjustments. The water heater will de-rate by 4% for each 1,000 feet above sea level up to 4,500 feet.

3. High altitude Armor water heaters are equipped to operate from 3,000 to 12,000 feet only with no field adjustments. The water heater will de-rate by 2% for each 1,000 feet above 3,000 feet. High altitude models are manufactured with a different control module for altitude operation, but the operation given in this manual remains the same as the standard models. A high altitude label (as shown in FIG. A) is also affixed to the unit.

4. The manual reset high limit provided with the Armor Figure A High Altitude Label Location is listed to UL353 and ANSI Z21.87.
