4. If filler section is desired to terminate the heater, install the
filler section in the end of the heater and extend to desired
length. Mark the mounting hole locations, remove the filler
section and drill the required mounting holes. Install the filler
section in the heater and the end cap on the filler section as
shown in Figure 2.
N N o o t t e e : : If a thermostat and/or disconnect switch are installed in
the heater left junction box, it may be necessary to cut away a
portion of the filler section to allow access to these controls
(Figure 2).
5 Position heater housing on wall to check for evenness of
wall. Do not draw the heater against an uneven wall surface.
If an uneven wall is encountered, use shims to keep the
heater housing straight.
6. Run proper size branch circuit to the junction box through the
selected knockout.
7. Drill the required size mounting holes in the back of the
heater housing and install the housing on the wall using
screws, bolts or anchors (by installer) to suit the wall con-
struction.
N N o o t t e e : : Predrilled 1/4" diameter mounting holes are provided in
each junction box. Additional mounting holes will have to be
drilled in the housing to support the weight of long length
heaters (6' and longer). Do not drill any additional holes in the
junction boxes.
8.
Tighten mounting screws and back off 1/4 to 3/4 turn to
allow for expansion and contraction of the heater.
9.
Following the wiring diagram secured to the heater, make
electrical connections. Ground the heater using the ground
screws provided (Figure 2).
10. Replace front cover and secure with mounting screws. (See
Figure 2).

N N o o t t e e : : For ease of installation, it is important that the sequence
of operations indicated below be followed in order.
1. Remove all the front covers from the heaters by removing
mounting screws (Figure 2).
2. Refer to wiring diagram for power supply entry and remove
appropriate electrical knockout (Figure 3) from the heater in
which power supply connections are to be made. The power
supply may be brought in to the end of only one heater and
the remaining heaters may be connected in parallel using the
wireway. Use Table B to size the field installed wiring in the
wireway.
3. If conduit cover (must be purchased separately) is desired,
cut off the appropriate length and install to the wall.
4. If required by plan, install filler section (1, Figure 1) to either
heater (2) or (3) by means of four #6 screws supplied with
filler section. (Refer to Figure 5.) Discard filler section end
cap in this application.
N N o o t t e e : : Heaters may butt against each other, thus eliminating the
filler piece, if so desired.
N N o o t t e e : : If a heater has a disconnect switch and / or thermostat
and is to have a filler section or a corner section at the left end,
the section must be mounted to the heater since the thermostat
or disconnect switch will prevent the section from telescoping
into the heater.
5 If the wall run has inside or outside corners, install corner (4
and 5) to the heater (2 and 9) by means of four #6 screws
supplied with corner section. (Refer to Figure 5).
6. Install end caps (6) on the outer end of the last heater(7) and
(9) using four #6 screws supplied with end caps. (Refer to
Figure 4 for details of end cap installation.)
7. Drill the required size mounting holes in all the heater hous-
ings.
