CAUTION
Do not provide power to the heater from the
high voltage side of a time clock or pump relay.
Doing so may cause damage to the heater or
surrounding plumbing.
ATTENTION
N’installez pas l’alimentation électrique de
l’appareil du côté haute tension d’un relais
d’horodateur ou de pompe. Vous risquez
d’endommager l’appareil de chauffage ou la
tuyauterie qui l’entoure.

To wire the LX and LT Low NOx heater to a
115V or 230V /60 Hertz (Hz) electrical source:
1.
Remove the door of the heater.
2.
Remove the screws that hold the raceway cover
and allow the cover to slide down.
3.
Connect the wires from the power source to the
leads on the right side of the heater in the space
behind the raceway. You may need to remove
the control to gain access to the leads (See Fig.
19).
NOTE:
No external junction box is required.
6.2.1 Converting the Heater for a 115V
Power Source
To convert the LX and LT Low NOx heaters to
115 Volt, 60 Hz AC requires reversal of the voltage
selector board on the power distribution board. The
following procedure should be performed
before
the
heater is connected to a power source:
1.
Identify the power distribution board on the
heater. It is located to the left of the fan intake
on the raceway (see Figure 20).
2.
Cut the plastic wire tie that is holding the voltage
selector board in place and discard the wire tie.
Unplug the voltage selector board from the
receptacle (see Figure 21).
3.
Rotate the voltage selector board 180° and
reinsert it into the receptacle so that the hole in
the board is not visible. Be sure that the board is
securely seated in the receptacle.
Note:
The voltage selector board is keyed so
that it will fit in only one direction for either
selected voltage (either side of the board).
6.3 Bonding
CAUTION
This heater must be connected to a bonding
grid with a solid copper wire not smaller in
diameter than 8 awg.
ATTENTION
L’appareil de chauffage doit être connecté à
une grille de mise à la terre par un fil de cuivre
d’un diamètre de calibre minimal 8.
