Aqua-Hot Maintenance
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 required,
fill the expansion tank to the “HOT” level mark. Reference
Figure 128. Be sure to reference pages 102-103 for the type of
antifreeze and heating solution.
Additionally, it is recommended that the diesel burner be fired
and allowed to run monthly to keep it in good working order.

Failure to disconnect all power supplies and/or to
allow the heater to cool before servicing could cause
serious damage or personal injury.
NOTE:
Be sure to use care when handling the fuel nozzle.
Oils and/or small dust or dirt particles from hands may
plug the nozzle’s small orifice. A partially plugged orifice will
restrict fuel flow, which will affect the combustion process of
the diesel burner.
Annual Maintenance:
To keep the Aqua-Hot running smoothly, it is recommended to
have the diesel burner tuned up annually or after the RV has
been stored unused for a long period of time. 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 recommended fuel
nozzle and fuel filter when replacing these parts.
