4. Standard 75ºC wiring must be used in junction boxes, wire-
ways, blank sections, filler sections, and corner sections.
Room Layout
Refer to heating plans for exact room arrangements of heaters
(with or without thermostat and/or relays and/or switches and
accessories.)
Check the heater section dimensions and the additional wall
length required for telescoping accessories (Figure 2) before
starting wall-to-wall type installation. Be certain all heaters and
accessories needed are at hand and are of correct finish.
Installation of Single Unit
Note: For ease of installation, it is important that the sequence
of operations indicated below be followed in order.
1. Remove front cover by removing mounting screws (Figure
3).
2. Remove appropriate electrical knockout from either junction
box. See Figure 4 for location of knockouts.
3. Install end caps (must be purchased separately) on both
ends of the heater housing. Refer to Figure 5 for details of
end cap installation.
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 3.
Note: 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 3).
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.
