6. If one or more heaters are connected to a single branch circuit, determine the
total ampere load (see Nameplate), then determine the power supply wire size
and the circuit breaker or fuse size required. (See Table 2)
Table 2.
Minimum Circuit
AWG Wire Breaker
Total Size or Fuse
Amps (Copper) Size
0 thru 12 #14 15 Amp
12.1 thru 16 #12 20 Amp
16.1 thru 24 #10 30 Amp
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.
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.
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 1/2-turn to allow the back panel to
expand and contract.
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).
INSTALLATION OF MULTIPLE UNITS
1. With heaters mounted end-to-end, allow 1/32-inch (1mm) of expansion space
per heater between each heater.
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
LEADS.
