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.

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.

BIB-VVSO1 or BIB-VVSO2 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. C C A A U U T T I I O O N N – 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 905 and 909 series units and 45

amps for 912 series 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.

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 905 and 909 series units, and up to

45 amps in, 912 series units. Refer to Table C and D for

maximum length of heater run when the heaters are

connected in parallel.
