Wiring the Heat Exchangers:
1. Within each heating zone, run an 18-gauge wire -
black for negative, from each heat exchanger’s black
wire to the chassis ground source. Reference Figure
23.
2. Within each heating zone, run one 18-gauge - red for
positive, from the heat exchanger farthest from the
Aqua-Hot past all other heat exchangers in that zone
to the terminal block.
3. Within each heating zone, connect the red heat ex-
changer wires to the 18-gauge wire ran in step 2. Be
sure that the wire end (farthest from the Aqua-Hot)
is either attached to the last heat exchanger or cov-
ered to prevent additional connections.
4. Attach each zone wire ran in step 2 to the Aqua-Hot
terminal block - position F1 for zone 1 and position
F2 for zone 2. Reference Figure 22. Tighten the
screw in the terminal to secure the wire in place.
5. Label the wires indicating the heating zone they per-
tain to (e.g., Living Room, etc.)

NOTE: It is recommended that the wire numbers in Appendix
A be used when installing the Aqua-Hot in order to as-
sist with differentiating between the separate heating
zones and to aid service personnel with troubleshooting.
