General Operation
How the water heater operates
The Outdoor Armor water heater uses an advanced stainless
steel heat exchanger and an electronic control module that
allows fully condensing operation. The blower pulls in gas and
air and pushes flue products out of the water heater through the
heat exchanger and flue piping. The control module regulates
blower speed to control water heater firing rate. The gas valve
senses the amount of air flowing into the water heater and
allows only the right amount of gas to flow.
Sequence of operation
Table 1A shows control module normal sequences of operation
for water heating operation.
