Legacy™ Model LRZM Pool/Spa Heater
Refer to your local installation codes for more
detailed information. The valve setting should be
at or below the maximum working pressure of any
component in the filter system. The maximum working
pressure of the Legacy Model LRZ millivolt heater is
5.1 bar.

auxiliary Components,
Chlorinators, ozone Generators,
and sanitizing Chemicals
The Legacy Model LRZ millivolt heater is
manufactured with materials that are not compatible
with high concentrations of ozone, chlorine, bromine,
or other sanitizing chemicals. Heater damage caused
by excessive chemicals or improper ozonization is not
covered by the Zodiac warranty. Be sure to adhere to
the following:
•
When ozone is injected upstream of the heater,
install an offgas mixing chamber, or an ozone
bypass system between the heater and the ozone
injector to prevent ozone and air from entering
the heater.
•
When chemical feeders are used, plumb the
feeder downstream of the heater and install
an in-line check valve between the heater and
the feeder (a minimum of 450 mm is required
between the heater and the check valve).
•
Wire any electrical chemical feeder so that it
cannot operate unless the filter pump is running.
If the feeder has an independent clock control,
synchronize it with the filter clock.
•
Never deposit chemicals directly in the pool
skimmer.

WarninG
This product must be installed and serviced by a
contractor who is licensed and qualified in pool
equipment by the jurisdiction in which the product
will be installed where such state or local require-
ments exists. In the event no such state or local
requirement exists, the installer or maintainer must
be a professional with sufficient experience in pool
equipment installation and maintenance so that all
of the instructions in this manual can be followed
exactly. Before installing this product, read and fol-
low all warning notices and instructions that accom-
pany this product. Failure to follow warning notices
and instructions may result in property damage,
personal injury, or death.
Caution
Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
servicing.
6.1
Main power
The Legacy heater does not require an external
source of electrical power to operate. The power for
the gas valve and safety circuit are generated by a
thermopile. The thermopile generates a millivolt signal
when heated by the pilot flame. Figure 15 shows the
internal electrical wiring diagram and schematic of the
heater.
6.2
earth Bonding
Caution
To prevent premature failure of the appliance result-
ing from stray voltages and voltage differentials, the
heater must be bonded to other equipment which is
part of the pool plumbing system with a solid copper
wire not smaller in diameter than 8 AWG (10mm
2
).
Zodiac requires that the appliance be connected
to an "earth bonding loop" that includes all electrical
equipment in the system and on the equipment pad.
Earth bonding lugs must be connected with a solid
copper wire not smaller than 8 AWG (10mm
2
). Failure
to do so will void warranty.
Additionally, all metallic components of a pool
structure, including reinforcing steel, metal fittings
and above ground components be bonded together
(forming an “earth bonding grid”) with a solid copper
conductor not smaller than a 8 AWG (10mm
2
).
