SECTION 5 –
APPLIANCES AND SYSTEMS
5-8
The Hydronic Heating System can be
operated off of the 120-volt AC electric heating
element or the 12-volt DC diesel burner.
NOTE: Please note that the diesel burner is the
primary heat source for heating both the
interior and the domestic hot water (such
as when cool ambient temperatures exist
and/or when there is a high demand for
domestic hot water).
It is recommended that when starting up your
RV in extreme cold weather conditions or when
you are planning on taking a longer shower, to
turn on the diesel burner switch located on your
interior control switch panel.
If you normally run the Hydronic Heating
System off of the 120-volt AC electric heating
element only, it is recommended to fire up the
diesel burner monthly as routine maintenance.
Increasing and Decreasing Water
Temperature
A tempering valve is located on the back side
of the Aqua-Hot unit for regulating the
temperature of the hot water.
Turning the tempering valve an 1/8 of a turn
either way will dramatically increase or decrease
the water temperature.
•
Turn tempering valve COUNTER-
CLOCKWISE to INCREASE water
temperature.
•
Turn tempering valve CLOCKWISE to
DECREASE water temperature.
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.
