Diesel Burner Operation
The
Diesel-Burner will continue to produce heat in this manner until
it is switched off either manually or by the
ETS Module, which occurs
when the coolant temperature in the Aqua-Hot’s
Boiler Tank reaches
190°F (±5).
Once the
Diesel-Burner has switched
OFF
, the
Motor and
Combustion Air Blower
will continue
to operate for approximately 2-3 minutes. This
process is referred to as the
purge-cycle
.
NOTE:
Whenever the Diesel Burner is switched OFF by the ETS Module, it
will automatically be reactivated once the Aqua-Hot boiler tank’s coolant
reaches the present temperature of approximately 160°F (±5°).
