Heat Exchanger Locations and
Clearances
• Position the heat exchangers so that even heat is distributed
throughout the RV interior.
• The first heat exchanger on the loop will output the most
interior heat.
• It is best practice to place the heat exchanger in an area
where it can be easily accessed for maintenance.
• Place the heat exchangers as close to the floor as possible
for best performance.
• If a heat exchanger is kept in the fresh water storage bay,
then the last heat exchanger in the coolant loop should be
used.
• The heating air supply may be fresh or recirculated air that
is drawn from a clean area not likely to be contaminated.
Aqua-Hot advises against placing a heat exchanger on the
slide-out section of any vehicle due to the high probability
of damage occurring to the heating loop from moving parts.

Mounting the Heat Exchangers
1. Cut out a 2.5” x 10” (7cm x 26cm) opening for each heat
exchanger outlet and cold-air return grate as shown in
Figure 64.
2. Mount each heat exchanger permanently into place. There
are 4 tabs on both sides - see Figure 77.
3. Install the hot-air outlet and cold-air return grate.
A minimum of supply ventilation cross-sectional area of at
least 29in
2
(74cm
2
) must be supplied to each heat exchanger.
If the toe-kick area is inadequate to house a heat exchanger
for regular installation, a plenum assembly may be purchased
to redirect air via ducting. Refer to Figure 71.
