AVERTISSEMENT
Pour votre sécurité personnelle lorsque vous
mettez l’appareil en marche, tenez votre tête et
votre visage loin du brûleur pour éviter tout
risque de blessure.
WARNING
Vent pipes, and heater tops get hot! These
surfaces can cause serious burns. Do not
touch these surfaces while the heater is in
operation.
AVERTISSEMENT
Les tuyaux d’aération et le dessus de l’appareil
deviennent chauds! Ils peuvent causer de
graves brûlures. Ne touchez pas à ces
surfaces lorsque l’appareil est en marche.
CAUTION
Do not use this heater if any part has been
under water. Immediately call a qualified
service technician to inspect the heater and
replace any part of the control system and any
gas control which has been under water.
ATTENTION
N'utilisez pas cet appareil s'il a été plongé dans
l'eau, même partiellement. Faites inspecter
l'appareil par un technicien qualifié et
remplacez toute partie du système de contrôle
et toute commande qui ont été plongés dans
l'eau.
CAUTION
Should overheating occur or the gas supply fail
to shut off, turn off the manual gas control valve
to the heater.
ATTENTION
En cas de surchauffe ou si l'alimentation en
gaz ne s'arrête pas, fermez manuellement le
robinet d'arrêt de l'admission de gaz.
CAUTION
Do not attempt repairs on the gas controls or
appliance. Tampering is dangerous and voids
all warranties.

système de régulation du débit du gaz ou à
l’appareil. Toute modification non autorisée est
dangereuse et entraîne l’annulation de toutes
les garanties.

Operating Instructions
7.1 Normal Operation
The LX and LT-Low-NOx heaters are capable
of automatic operation based on a call for heat at
preset temperatures and an operator selection between
pool or spa settings. Additionally, the heater may be
controlled by a remote unit to anticipate bather load,
changes in temperature settings, or a variety of other
demands that might be encountered. 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 controls scheme, enabling faster service and
less down time in the event of a failure.
When the heater is powered, water is flowing
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 combustion blower is started and operates
at high (normal) speed. If the blower pressure switch
senses adequate airflow, the ignition sequence starts.
First, a fifteen second pre-purge takes place. Next,
the blower speed is reduced and the igniter is ener-
gized. After forty seconds of igniter heat-up time the
gas valve is opened (approximately one minute after
the call for heat). If flame is sensed at the burner
within seven seconds, operation continues and the
blower resumes high (normal) speed. Operation will
continue until the temperature of the water entering
the heater reaches the temperature control setting.
If ignition is unsuccessful, or if the flame fails
during normal operation, the ignition control shuts off
the gas valve. It imposes a post purge, initiates addi-
tional ignition cycles, and shuts down the system if
ignition is not achieved in three cycles.
To reset the model LX Low NOx for another
three cycles, press and release the mode button until
the indicator on the LCD screen aligns with "OFF".
Now press and release the button again until the
indicator on the LCD screen aligns with the desired
setting, either "POOL" or "SPA".
To reset the model LT Low NOx, press and
release the mode button until the indicator lights for the
"SPA" and "POOL" settings are off. Then press and
release it again until the indicator light for the desired
setting is back on.
7.2 Start-Up
WARNING
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.
