7.Install the power supply wire to the heater location and thermostat location as determined by the thermostat option selected. If the power supply enters through the knockout in back of the heater, install a cable connector (not includ- ed) on the power supply wire and insert in knockout, leaving 6 (152mm) to 8 inches (203mm) of wire for heater connection.
8.If the power supply enters the heater through the hole in bottom portion of the junction box, a cable connector is not required.

The following methods of mounting the heaters to common types of wall sur- faces are suggested:
a.Plaster Walls: Use toggle or molly screw anchors.
b.Wall Studs: Use #12 round head screws penetrating at least 3/4" (19mm) into stud.
c.Masonry Walls: Use #12 round head screws into lead, plastic, or fiber expansion anchor.
Tighten all screws snugly, then back off
10.Connect supply wiring to heater as described in Figure 6, or as shown in the wiring diagrams supplied with the accessory kits intended for use with this heater.
11.Secure the desired accessories to baseboard as shown in the accessory instruction sheet, and use the wiring diagram supplied with the accessory.
NOTE: Baseboard heaters must be thermostatically controlled.

12.Replace the front cover by fitting the top lip of the cover onto the tabs on each junction box and top edge of the element support bracket(s). Rotate the cover downward, pushing the bottom corners inward. Install two screws (removed
in Step 4) through the cover into the junction boxes. See that the bottom of
the cover is engaged onto the bottom of each element support bracket. See Figure 7.

13.Replace the end cap(s) by installing screw(s) (removed in Step 3).
CAUTION !
POWER SUPPLY CABLE MUST BE ROUTED AS SHOWN IN FIGURE 5 TO
PROVIDE THE NECESSARY STRAIN RELIEF SYSTEM.
9.Position the heater on the wall and locate wall studs. Drill, punch, or use nail dri- ver to put holes through the enclosure back (above the element) at stud loca- tions.
NOTE: The heater enclosure is provided with nail point marks showing cor- rect locations for mounting holes.
INSTALLATION OF MULTIPLE UNITS
1.With heaters mounted
2.For each heater to be installed, refer to and follow “Installation of Single Unit”, Steps 1 through 8.
3.If the power supply is to enter through the end of the heater series so that the end cap can be installed after the heaters are installed, continue “Installation of Single Unit”, Steps 9 through 12.
4.If the power supply is to feed heaters at the junction box that is adjacent to
