gaskets and clean the header's mating surface of
any corrosion or debris. Replace the tube gaskets
with new ones. Do not use any metal tools on the
header surface. Scratches may compromise the
seal integrity.
WARNING
To avoid product failure which can cause property
damage, serious personal injury or death, install
the inlet/outlet header oriented so that the high limit
devices on the bottom.
12. Place the inlet/outlet header over the bolts and
gasketed tubes on the left side of the tube as-
sembly. Make sure the high limit devices are on
the bottom. Align the bolt and tube holes in the
header with the bolts and tubes in the header bar
and slide the assembly together.
13. Thread on the 10 bolts and washers and hand
tighten.
14. Place the return header over the bolts and gasket-
ed tubes on the right side of the tube assembly.
Align the bolt and tube holes in the header with
the bolts and tubes in the header bar and slide the
assembly together.
15. Thread on the 10 bolts and washers and hand
tighten.
16. Use a torque wrench to tighten the bolts on each
header to 4 foot-pounds. The bolts must be tight-
ened in the sequence indicated in Figure 14.
CAUTION
Failure to tighten the header as indicated in step 16
may cause the header to leak or become perma-
nently damaged from warping.
ATTENTION
Si le tuyau collecteur n’est pas serré conformément
aux directives des l'étape 16, il risque d’avoir des
fuites ou de s’endommager de façon permanente.
17. Remove the 3/4 inch button plug located in the
left side panel below the inlet/outlet header and
replace with the 3/4 inch wire grommet from
the right side panel below the return header. The
high limit leads were routed through this grom-
met prior to removal in step 5. Install the 3/4
inch plug in the opening where the 3/4 inch wire
grommet was removed.
18. Route the blue two-pin connector attached to the
high limit switches back to the Power Interface
board in the raceway. Reconnect the blue “Hi-
Limit” two-pin connector to the blue “HiLimit”
connector on the Power Interface board.
19. Route the wires that attach to the temperature
sensor back to the Power Interface board in the
raceway. Reconnect the wires to the “WATER
TEMP” terminals on the Power Interface board.
20. Route the yellow two-pin connector that connects
to the water pressure switch back to the Power
Interface board in the raceway. Reconnect the
yellow two-pin connector to the yellow “Water
Press” connector on the Power Interface board.
21. Use plastic wire ties to refasten the temperature
sensor, high limit switch and water pressure
switch wires to each other. Bundle the wires near
the control panel and fasten them with a wire tie.
NOTE
Be sure that none of the wires are in contact
with a sharp edge or a hot surface.
22. Install the return header side cover plate on the
right side of the unit.
23. Install the I/O header side cover plates, top and
bottom on the left side of the unit.
24. Replace the front panel (door).

Connections at Heater
The LXi heater has a standard 2 inch water
header and coupling design. With this feature, only
nominal two inch PVC or CPVC may be connected to
the heater. However, by installing the appropriate pipe
adapters and two (2) short pieces of two-inch plastic
pipe (supplied by the installer), any size existing pipe
may be fitted to the heater.
The LXi heater also comes with a Zodiac Sweep
Elbow for increased hydraulic performance and ef-
ficiency. The sweep elbow also provides the advantage
of its exclusive interface with the Zodiac AquaLink
®
RS temperature sensor.
To install the Zodiac Sweep Elbow follow these
instructions:
WARNING
To avoid an electrical shock hazard, which can
result in serious injury or death, ensure that all elec-
trical power to the system is turned off before ap-
proaching, inspecting or troubleshooting any leaking
valves or plumbing that may have caused other
electrical devices in the surrounding area to get wet.
