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
