Installation and Operation Manual

   Jandy® Legacy™ Model LRZM Pool/Spa Heater by Zodiac®

3.  Use the figures in Table 4 to size the gas inlet 

piping from the gas meter to the heater. Check all 

local codes for compliance before installing the 

heater.

4.  Install a sediment trap (drip leg) ahead of the gas 

controls, see Figure 6. Fit the trap with a threaded 

cap which can be removed for cleaning.

Figure 6.  Proper design for a Sediment trap/drip Leg

APPROVED

5.  Install a manual gas shutoff valve for service 

and safety. Do not use a restrictive gas cock. 

DO NOT USE FLEXIBLE GAS PIPING, it will 

restrict the gas flow to the heater.

6.  Disconnect the heater and its individual shutoff 

valve from the gas supply system during pressure 

testing of the system at pressures higher than 1/2 

pounds per square inch (psi) (3.45 kilopascals 

[kPa]). If the test pressure is equal to or less than 

1/2 psi (3.45 kPa), close the manual shutoff valve 

on the heater during the piping pressure test.

7.  If the gas supply pressure is less than required, 

check for undersized pipe between the meter and 

the heater, a restrictive fitting, or an undersized 

gas meter. Gas supply pressures to the heater are 

listed in Table 5.

Note 

The maximum inlet gas pressure must not 

exceed the specified value. The minimum 

value listed is for the purpose of input 

adjustment. Refer to Table 5.

8.  Before operating the heater, test the complete gas 

supply system and all connections for leaks using 

a soap solution. Do not use an open flame.

 cautioN

Some leak test solutions (including soap and water) 

may cause corrosion or stress cracking. Rinse the 

piping with water after testing. 

 atteNtioN

Certaines solutions d’essai d’étanchéité (y compris 

l’eau et le savon) peuvent causer de la corrosion 

ou de la fissuration. Rincez les tuyaux à l’eau après 

l’essai d’étanchéité.

4.2 

Manifold Pressure

Confirm that gas supply pressure is correct. If 

the gas supply pressure is less than required, check 

for undersized pipe between the meter and the heater, 

a restrictive fitting, or an undersized gas meter. Gas 

supply pressures to the heater, when it is operating, are 

listed in Table 5.

 cautioN

Manifold gas pressure for the Legacy natural gas 

heaters should be set at 

4.0" 

WC. Propane heaters 

should be set to 9" WC.

 atteNtioN

La pression du collecteur de pression pour les 

systèmes de chauffage au gaz naturel devrait être 

de 4.0'’ WC. Pour les sytèmes de chauffage au gaz 

propane devrait être de 9'’ WC.

Notes:

 

*1. These numbers are for natural gas (0.65 Sp. Gr.) and  

are based on 1/2 inch (3.45 kPa) water column pressure 

drop. Check supply pressure with a manometer, and local 

code requirements for variations.

 For LP gas, reduce 

pipe diameter by one size, but maintain a minimum 

3/4" diameter.

2.  Check supply pressure and local code requirements before 

proceeding with work.

3.  Pipe fittings must be considered when determining gas 

pipe sizing.
