Section 7. Operating Instructions
7.1 Normal Operation
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.
7.2 Start-Up
For your safety, when starting the heater, keep
your head and face well away from the burner
area to prevent any risk of personal injury.
