FOR HEATERS RATED 240 VOLTS:
1. Connect the black (L1) heater pigtail to the black power lead.
2. Connect the red (L2) heater pigtail to the other black power
lead.
NOTE:
If power supply is provided by standard non-metallic
sheathed cable (Romex) and the supply voltage is 240 volts (two
power wires), the white wire color must be changed using black
electrical tape to comply with the NEC. White is only allowed for
a Neutral conductor.

ment ground wire coming into heater.
4. Push wires up into right hand corner of box out of way.
ALL HEATERS:
Position junction box cover in place making sure flat ribbon cable
is fitted into elongated slot in cover as shown in Figure 4.
Secure cover in place using the 4 screws provided.

Approximately 3-1/2 inches (89 mm) of ribbon cable
should be extending through the slot for connection to electron-
ics in grille. Orientation of connector must be as shown in
Figure 4.
Installation of Grille and Ribbon Connector
1. While holding the right side grille in your right hand, extend
the ribbon connector with the free hand and fit the black con-
nector into the black slot located on the back of the electronic
control, behind the grille. The connectors are keyed so it will
fit only one way (Figure 4).
NOTE:
Press the connector gently and firmly, but do not force.
2. Once connected, position the grille over heater back box
assembly aligning top of grille with the flanges along top of
back box.
3. Reach behind the grille and push excess ribbon back into the
slot in the junction box cover to avoid unnecessary bends in
the ribbon. Lower top of grille so the grille flanges catch the
back box flange and hold it in place.
4. There are two holes in the bottom bezel area of the grille that
align with two holes in the heater assembly. Insert the two
screws in these holes and tighten (Figure 5).
5. Place the lower bezel in position over the grille and snap
tabs into the corresponding holes making sure it is seated
securely.
