INSTALLATION INSTRUCTIONS

Rough-in Wiring

1. Run branch circuit of proper voltage and wire size to location

of left or right junction box as indicated on heater wiring dia-
gram. Basic heaters are prewired and can be connected to
branch circuit at either end. Heaters with controls are
prewired for connection to branch circuit at one end only
(refer to heater wiring diagram), however, heater can be
wired from opposite end by running wire through heater wire-
way.

2. If it is necessary to run wires through the heater wireway,

use Table B to size the field installed wiring.

3. The factory installed wires in the heater wireway can be

loaded up to 35 amps in CSH05 and DSH05 units, and up to
45 amps in, CSH05, CSH14, DSH07 and DSH14 units.
Refer to Table C and D for maximum length of heater run
when the heaters are connected in parallel.

TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK
OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Serious injury or death could result from electric shock.

Make sure electrical power supply circuit coming to heater
is disconnected at main disconnect or service panel before
installing this heater.

2. Wiring procedures and connections must be in accordance

with  the  National  Electrical  Code  (NEC)  and  local  codes.
Refer to Wiring Diagram on heater and Figure 8 as well as
Tables  B  and  C.    Make  sure  all  electrical  connections  are
tight to prevent possible overheating.  Use Copper Supply
Wire Only.

3. Verify the electrical power supply voltage matches the volt-

age rating as printed on the heater nameplate.

CAUTION - Never connect a heater to a voltage greater than
the nameplate voltage as this will damage the heater and
could cause a fire.

4. Remove and discard foam packing material inside heater

before installing or energizing the heater.

5. Do not install the heater against combustible low-density

cellulose  fiberboard  surfaces,  against  or  below  vinyl  wall
coverings, or below any materials that may be damaged by
heat such as vinyl or plastic blinds, curtains, etc.   If heater
must  be  installed  against  vinyl  surfaces  or  surfaces  that
may  be  damaged  by  heat,  Standoff  Kits  Cat.  No.  S01  or
S02  must  be  used.    Refer  to  installations  instructions
provided with these kits when installing.

6. Do not install heater below an electrical convenience recep-

tacle (outlet).

7. CAUTION – Heater Operates at High Temperatures. Keep

Electrical Cords (including telephone and computer cables),
Drapes, and Other Furnishings Away From Heater. For effi-
cient and safe operation, we recommend maintaining a min-
imum of 6 inches (152 mm) clearance above and in front of
the heater at all times. See Clearances Chart for minimum
clearance requirements.

8. To reduce the risk of fire, do not store or use gasoline or

other flammable vapors or liquids in the vicinity of the
heater.

9. Do not install heater upside down or in any position other

than as shown in this manual.

10. Do not recess heater in wall or install heater inside any type

enclosure (unless specifically approved by the manufactur-
er) as this will cause heater to overheat and could create a
hazard.

11. When mounting heater, use care when drilling mounting

holes and mounting heater to building structure to avoid
damaging internal heater components. Be sure to loosen
mounting screws 1/4 to 3/4 turn to allow for expansion and
contraction.

12. Do not remove or bypass the safety limit control(s) as this

could allow heater to become a fire hazard – see heater
wiring diagram supplied with heater.

13. The factory installed wires inside wireway are used to con-

nect the built-in controls.  Limit the maximum current to no
more  than  35  amps  for  CSH05  and  DSH05  units  and  45
amps for CSH07, DSH07, CSH14 and DSH14 units.  Refer
to instructions and current capacity rating as provided with
the accessory.

14. Heaters that are not installed end to end must have end

caps  installed  to  cover  exposed  ends  of  heater.  Heaters
joined  together  must  have  appropriate  filler  sections  or
other  approved  assemblies  (see  Accessories  Data  listing
on  Page  8)  installed  to  cover  exposed  openings  between
heaters.

15. All field wiring brought into the heater or any attached

accessories must be rated at least 75 °C.

16. Do not allow objects to be placed on top of heater as they

may be damaged or create a fire hazard.

17. Before energizing, make sure front cover is properly

installed onto the back housing along the entire length of
the heater – See Fig. 4. Do not operate heater without front
cover installed.
