Jandy® Legacy™ Model LRZE Pool/Spa Heater by Zodiac® | 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 effects 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

Zodiac Pool Systems, Inc., offers the following

recommendations to help conserve fuel and minimize

the cost of operating your pool heater without

sacricing comfort.

1. The American Red Cross® recommends a

maximum water temperature of 78°F (25°C). Use

an accurate pool thermometer. A difference of 4°F

(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 tempera-

ture control and use the Set Point Lockout feature

to discourage further adjustments.

4. Set the pump time clock to start the pump no

earlier 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 landscap-

ing, 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 lter systems.

1.3 Warranty

The Legacy Model LRZ electronic heater is sold

with a limited factory warranty. Details are specied on

the back cover of this manual.

Make all warranty claims to an authorized Jandy

representative or directly to the Zodiac Pool Systems,

Inc. factory. Claims must include the heater serial

number and model (this information 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 eld

modication. Also, damage to the heat exchanger by

corrosive water is NOT covered by the warranty. See

Section 8.1 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 Legacy Model LRZ electronic pool and spa

heaters are design certied by CSA (Canadian Standards

Association) as complying 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.

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

Installation Code", CAN/CSA-B149.1. However,

for minimum combustion air requirements,

table 3 of this manual MUST be followed for

proper and safe operation. The Jandy LRZ

electronic heater may not operate properly when

installed with the only the minimum combustion

air openings allowed in CAN/CSA-B149.1.

The Legacy Model LRZ electronic pool and spa

heaters meets or exceeds the requirements of energy

conservation regulations such as those in California,

Hawaii, New York, Oregon and other states which

require that a pool heater have intermittent ignition.

Any changes to the heater, gas controls, gas

orices, wiring, draft hood, vent cap, or improper

installation may void the warranty. If change is required

to any of the above, consult the factory.
