The Legacy Model LRZ electronic heater is
capable of automatic operation based on a call for
heat at a preset temperature. The heater has an internal
safety system which allows operation in a variety
of conditions and prevents operation when certain
adverse conditions are encountered. The heater is
capable of diagnosing problems within the safety
control scheme, enabling faster service and less down
time in the event of a failure.
When the heater's transformer is provided with
a 120 VAC or 240 VAC supply, it in turn provides a
24 VAC signal to the safety circuit. When water is
owing through the heater, and the temperature of
the water entering the heater is below the temperature
control setting, an operating cycle is initiated by the
automatic control. The control circuit is closed, the
igniter is energized. After a 40 second igniter heat-up,
the gas valve is opened. Gas ows through the burners,
is mixed with air in the combustion chamber, and
is ignited by the hot surface igniter. Operation will
continue until the temperature of the water entering the
heater reaches the temperature control setting.
If ignition is unsuccessful, or if the ame fails
during normal operation, the ignition control shuts off
the gas valve. To reset the Legacy heater to provide
three (3) additional attempts without waiting an hour,
turn the control off and return it to either pool or spa.
The ignition control will automatically reset itself and
restart the ignition after one hour.

Be sure that there is water in the pool and that the
surface level is above the skimmer or other inlet of the
pool's lter system.
Conrm that pool water is owing normally
through the pool system and equipment. With any
new pool or spa installation, operate the lter pump
with the heater off long enough to completely clean
the water. This will remove any installation residue
from the water. Clean the lter at the end of this
operation before starting the heater. Start the heater in
accordance with the Operating Instructions section of
this manual, with particular attention to the lighting
