Pool/Spa Heater Installation and Operation Manual
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and
an increase in the internal body temperature. The ef-
fects of hyperthermia include:
• Lack of awareness of impending hazard
• Failure to perceive heat
• Failure to recognize need to leave spa
• Physical inability to leave spa
• Fetal damage in pregnant women
• Unconsciousness resulting in a danger of
drowning
1.2.2 Swimming Pool Energy Saving
Tips
Jandy Pool Products, Inc., offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without sacri-
fi cing comfort.
1. The American Red Cross recommends a maxi-
mum water temperature of 78°F (25°C). Use an
accurate pool thermometer. A difference of 4F°
(2°C), between 78°F and 82°F (26°C and 28°C),
will use as much as 40% more gas.
2. Carefully monitor the water temperature of your
pool in the summertime. You can reduce heater
usage due to warmer air temperatures.
3. Find the proper setting on the pool heater tem-
perature control and use the Set Point Lockout
feature to discourage further adjustments.
4. Set the pump time clock to start the pump no ear-
lier than 6:00 AM during the pool heating season.
This is the time when nightly heat loss balances.
5. If the pool is only going to be used on weekends,
reduce the heater temperature control setting by
8 or 10 degrees during the week. Reset it to the
78°F (25°C) level a day or so before you plan to
use the pool.
6. During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found on the inside of
the heater.
7. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other land-
scaping, cabanas, or fencing.
8. Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on fi lter systems.
1.3 Warranty
The LXi heater is sold with a limited factory war-
ranty. Details are specifi ed on the back cover of this
manual.
Make all warranty claims to an authorized Jandy
representative or directly to the factory. Claims must
include the heater serial number and model (this infor-
mation can be found on the rating plate), installation
date, and name of the installer. Shipping costs are not
included in the warranty coverage.
The warranty does NOT cover damage caused
by improper assembly, installation, operation or fi eld
modifi cation. Also, damage to the heat exchanger by
corrosive water is NOT covered by the warranty. See
Section 8.1, Water Chemistry, for maintaining proper
pool water chemistry.
NOTE Keep this manual in a safe place for future
reference when inspecting or servicing the heater.
1.4 Codes and Standards
The LXi pool and spa heaters are design-certifi ed
by CSA (Canadian Standards Association) as com-
plying with the latest edition of the Standard for Gas
Fired Pool Heaters, ANSI Z21.56 in the USA and
CAN-4.7 in Canada.
All Jandy heaters must be installed in accordance
with the local building and installation codes as per
the utility or authorities having jurisdiction. All local
codes take precedence over national codes.
In the absence of local codes, refer to the latest
edition of the following national codes for installation:
1. In the United States, the National Fuel Gas Code,
NFPA 54/ANSI Z223.1. Pay particular attention
to the chapter addressing Venting of Equipment.
2. In Canada, the Natural Gas and Propane Instal-
lation Code, CAN/CSA-B149.1.
The LXi pool and spa heaters meet or exceed the
requirements of energy conservation regulations, such
as those in California, Hawaii, New York, Oregon and
other states that require that a pool heater have inter-
mittent ignition. In addition, the natural gas models
of this heater comply with both the California South
Coast Air Quality Management District's (SCAQMD)
Rule 1146.2 and the Title 30, Texas Administrative
Code, Chapter 117, Section 117.465 for Nitrogen
Oxide (NOx) emissions.
