Changing the Fuel Filter and Fuel
Nozzle
To keep the Aqua-Hot system running
smoothly, it is recommended to have the diesel
burner tuned up annually. This consists of
replacing the fuel filter and the fuel nozzle. To
ensure maximum performance, always replace
with the fuel filter and fuel nozzle recommended
for your Aqua-Hot system.
See “Winterizing Procedure” in Section 7 -
Plumbing (ANTIFREEZE FILL
PROCEDURE) for complete instructions in
winterizing your Hydronic Heating System. The
Aqua-Hot will be winterized along with the rest
of the RV water systems.
