Seasonal Care
CAUTION
Do not operate this heater outdoors at temperatures
below 20 degrees Fahrenheit (°F) (-7 degrees
Celsius [°C]).
ATTENTION
Ne faites pas fonctionner cet appareil à l’extérieur à
des températures inférieures à 20 degrés Fahren-
heit (
o
F) (-7 degrés Celsius [
o
C]).
8.2.1 Spring and Fall Operation
During periods when the pool is only going to be
used occasionally, set the pool and spa control temper-
atures to 70°F (21°C) on the LXi or the lowest setting
possible on the LXi. See
Section 7.3.3
. This prevents
the pool water from becoming chilled, and minimizes
the time required to raise the pool water back up to the
desired temperature.
If the heater is not going to be used for a long
period of time, shut it down completely. Follow the
instructions found on the inside of the heater, or refer
to Figure 31 of this manual.
8.2.2 Winterizing
In areas where freezing temperatures occur in
winter and the pool or spa will not be used, have your
service technician perform the following steps:
1. Turn off the main gas supply to the heater, using
the gas cock outside the heater jacket.
2. Remove heater door.
3. Shut down the heater following the shutdown
instructions found on the inside of the heater or
refer to Figure 31.
4. Remove the drain plugs from both the inlet/outlet
header and the return header, see Figure 35 and
Sections 11.3 and 11.4, Exploded Views, and
completely drain the heater before the first frost.

5. After all water has drained from the heater, check
for mineral buildup in the openings.
6. Use compressed air to blow out any standing
water remaining in the heat exchanger.
7. Inspect the gaskets on the drain plugs and rein-
stall plugs, but do not tighten.
8. Disconnect the pressure switch from the siphon
loop (copper tubing).
9. Cover the vent grill so that snow will not accu-
mulate in the combustion chamber, where it may
freeze.
8.2.3 Spring Start-up
To restart the heater in the spring, have a quali-
fied professional technician reassemble the heater as
follows:
1. Tighten the drain plug.
2. Uncover the vent grill.
3. Make sure that power is supplied to the pump.
Turn on the filter pump and circulate water
through the heater for 5 minutes. Check for leaks
while circulating.
4. Turn on the main gas supply to the heater at the
gas cock outside the heater jacket.
5. Turn on the heater following the lighting instruc-
tions found on the inside of the heater, or
Figure 31.

Inspection and Service
The LXi heater is designed and constructed to
provide long performance life when installed and
operated properly under normal conditions. Periodic
inspections, especially at spring start-up, are impor-
tant to keep your heater running safely and efficiently
through the years. Improper maintenance can result in
conditions where nausea or asphyxiation from carbon
monoxide or flue gases could cause severe injury,
property damage or death.
WARNING
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide in
flue gases which could result in severe injury, or
death.
AVERTISSEMENT
Une installation ou un entretien inadéquat peut
causer la nausée ou l’asphyxie en raison du
monoxyde de carbone présent dans les gaz de
combustion et même entraîner des blessures
graves ou la mort.
