General Operation
How the water heater operates
The 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.
