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.
Note: 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 3).
10. Replace front cover and secure with mounting screws. (See
Figure 3).
Installation of Multiple Wall to Wall Units
Note: 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 3).
2. Refer to wiring diagram for power supply entry and remove
appropriate electrical knockout (Figure 4) 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 6.) Discard filler section end
cap in this application.
Note: Heaters may butt against each other, thus eliminating the
filler piece, if so desired.
Note: 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 6).
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 5 for details of end cap installation.)
7. Drill the required size mounting holes in all the heater housings.
Note: Predrilled 1/4” diameter mounting holes are provided in
each junction box. These holes may be used only when no slip-
in accessory is to be installed in that end of the heater ( such as
when heater(3 and 7) are butted together as shown in Figure 2).
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 junction boxes.
8. Check for evenness of wall. Do not draw the heaters
against an uneven wall surface. If an uneven wall is
encountered, use shims to keep the heater housing
straight.
9. Run proper size branch circuit to the junction box through
the selected knockout.
10. Mount the heater (2, Figure 2) on the wall using screws,
bolts or anchors (by installer) to suit the wall construction.
11. Telescope the heater housing (3) over the filler section (1)
by the desire amount and mount the housing to the wall.
12. Telescope the heater housing (8) over the corner section
(4) by the desired amount and mount the housing to the
wall.
13. Mount the remaining heaters as described above, making
sure that the heaters with end caps are installed at the end
of the run.
14. Blank sections, if any are installed in the same manner as
the heaters.
Note: 75ºC field wiring may be run through the blank sections,
filler sections and corner sections.
15. Control sections, if any, are installed in the same manner
as heaters. Refer to wiring diagram on control sections for
connecting the wiring to the heaters
Installation of Mullion to Mullion Units
The back of the heater housing contains no mounting holes
(other than those at the ends) and therefore is ideal for installa-
tion in front of glass curtain walls. The housing back presents
an attractive appearance when viewed from the outside through
the glass wall.
Installation procedures are similar to those for wall-to-wall instal-
lation (Step Six) except for the following differences.
1. Attach the housing to the mullion using the mounting holes
provided in the junction boxes as shown in Figure 7.
2. On horizontal mullion installation, install support brackets as
shown in Figure 8.

OP RATION INSTRUCTIONS
1. This heater must be properly installed before it is used.
2. If the heater is equipped with a built-in thermostat, adjust the
shaft to the mid-range and let the heater run for a few hours.
If the room temperature is too hot, rotate the shaft counter-
clockwise; if too cool, rotate the shaft clockwise until a com-
fortable temperature is obtained. Let room temperature sta-
bilize after each setting change. The heater will automatical-
ly cycle around this set point on the thermostat.
Note: If a thermostat or disconnect switch is provided in the
heater, these components are accessible through the grille
openings at the left or right end of the heater.
MAINT NANC INSTRUCTIONS
For efficient and safe operation and to extend the life of the
heaters, they should be cleaned and inspected for damage at
least annually (preferably at the beginning fo the heater season)
or more often in dirty environments. Other than cleaning, your
heaters require no other preventative maintenance.
1. The user can perform periodic cleaning of the outer cabinet.
All other servicing is to be done by qualified service person-
nel.
2. Heater cabinet may be cleaned using a damp cloth to
remove dust that may have accumulated on surfaces. Do not
use harsh cleaners or waxes on surfaces since these could
damage the finish or discolor in use.
3. A vacuum cleaner and/or compressed air may be used to
remove dust and lint that may have accumulated inside
heater around element fins. If heater must be disassembled
for cleaning, use care when cleaning element fins to avoid
damaging fins.
4. After cleaning and servicing, always reassemble replacing
any hardware removed, restore power and check to make
sure the heaters are operating properly.
Important Note: There are built-in safety devices provided within
the heaters including one or more over-temperature limit con-
trols (Thermal Protector) - see Wiring Diagram on heater for
specific controls provided. These safety controls are provided to
cycle the heater off to maintain safe temperatures in the event of
a blockage or other abnormal condition. DO NOT remove or
bypass these important safety controls as they are provided to
limit the temperatures and prevent a possible fire in the event
the heater is subjected to an overheating condition. If it is deter-
mined that the heater is cycling off on the safety controls during
normal use, discontinue using the heater until it can be
inspected and repaired by a qualified service personnel.
1. Serious injury or death could result from electric shock.
Make sure electrical power supply circuit(s) coming to
heater is/are disconnected at main disconnect or service
panel before servicing this heater. Allow heater to cool
before cleaning to prevent a possible burn.
Note: More than one power source may enter heater. Be
sure all power is disconnected to heater before cleaning or
servicing.
2. Use care when cleaning element fins to avoiding damaging
fins. Note also that fins are sharp and may cause cuts so
avoid contact.
