Condensate Float Switch
The heater is equipped with a condensate float switch
to prevent operation when the condensate water level
is too high. The heater shutting down from the conden-
sate float switch is indicative of a blocked drain or
problem with the condensate management system.
The condensate float switch is located inside at the left
rear of the heater, and can be accessed through the
back panel.
