To keep the Aqua-Hot running smoothly, it is recommended
to have the diesel-burner tuned up annually. A tune-up
should consist of a new fuel nozzle and fuel filter, along with
a thorough cleaning of the combustion chamber. To ensure
maximum diesel-burner performance, always use the recom-
mended fuel nozzle and fuel filter when replacing these
parts.
NOTE:
Be sure to use care when handling the fuel nozzle.
Oils and/or small dust or dirt particles from the
hands may plug the nozzle’s small orifice. A par-
tially plugged orifice will restrict fuel flow, which
will affect the combustion process of the diesel-
burner.

Monthly Maintenance:
Check the antifreeze and water heating solution to ensure
that it is at the proper level by visually checking the solution
level in the expansion tank. The level of the antifreeze and
water heating solution within the expansion tank should only
be checked when the Aqua-Hot is at maximum operating
temperature.
If additional antifreeze and water heating solution is re-
quired, fill the expansion tank to the “HOT” level mark.
Additionally, it is recommended that the diesel-burner be
fired and allowed to run monthly to keep it in good working
order.
