Installation of the Expansion Bottle
Introduction:
The fluid expansion bottle is integral to the operation of the
Aqua-Hot. It provides an area for hot, expanded fluid to empty
into, and also protects the Aqua-Hot from low-fluid, which could
lead to catastrophic damage of the Aqua-Hot.
Follow the directions in this section to correctly install the
fluid expansion bottle.
Installation Procedure:
1. Place the expansion bottle in position on the side of the
Aqua-Hot or other mounting location in the RV.
2. Secure the expansion bottle using either self-tapping
screws driven into the dimples in the area of the Aqua-Hot
shown in Figure 18, or mounting hardware specific to the
mounting location in the RV. Please only use the length
of hose provided, or less, if the bottle is not mounted to
the side of the Aqua-Hot. Additionally, there should be a
gradual rise from the Aqua-Hot to the expansion bottle if it
is not mounted to the Aqua-Hot.
3. Drill a hole in the floor of the RV to allow the overflow tube
to vent to the exterior of the vehicle (Figure 19).
4. Cut the hoses to length if necessary.
5.
Place a hose which runs from the lower fitting of the
expansion bottle to the expansion bottle connection shown
in Figure 17. Secure this hose in place with 2 constant
tension hose clamps.
6. Place the overflow hose so that it connects to the upper
fitting of the expansion bottle, and exits through the hole
drilled through the RV floor in step 3 (Figure 19). Secure
this hose to the upper fitting with a constant tension hose
clamp.
7. Locate the wires of the expansion bottle and connect them
to wires J43 and J44 on the wiring harness.
NOTE: Avoid any bends or dips in the overflow tubing from
the Aqua-Hot. Air can become trapped in these bends and
will prevent excess antifreeze and water heating solution
from depositing properly in the expansion bottle.

NOTE: Before securing the expansion bottle to the side of
the Aqua-Hot or its mounting location, the boiler tank must
be filled with the heating solution. The expansion bottle must
be higher than the unit for this to happen to avoid air locks.
See “Filling the Aqua-Hot” on page 38 for more information.

• The burner must be fastened on the bracket with at least 3
M5 bolts (see Figure 23).
• The burner fastening screws are approved for bracket
metal thickness of 0.06in - 0.12in.
• The images below are examples of the burner bracket with
dimensions.
Mounting the Burner to the Vehicle
Install the external diesel burner in a location separate from the
living spaces that protects the unit and allows service access
to the burner.
• Reference the following illustrations below for mounting
information.
• Secure the burner to the bracket using appropriate
mounting hardware, at least (3) M5 bolts torqued to 6 lb-ft.
• The bracket must be secured to the vehicle with at least 4
M6 screws.
• The burner is best placed in a location where it can be
easily accessed for service and maintenance.
• The burner must not be mounted higher than the expansion
bottle.
