GENERAL INFORMATION

ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property dam­age. Heater must be installed by a qualified person
in accordance with the National Electrical Code,
NFPA 70.

1. All wiring should be done in accordance with local codes and the
National Electrical Code by a qualified person.

2. Connect air heaters to same line voltage as on heater nameplate.

3. Check possibility of corrosion if heaters are operated in atmos-

pheres other than air.

4. In general, locate heater approximately 1 foot from the floor, but
not less than 6 inches, for best overall results. Heater, however, can
be located anywhere to meet unique requirements of any particu­lar application.

5. Heaters are mounted directly on any type of noncombustible sur­face—masonry, concrete, block, plastered walls, metal framework,
etc.— using appropriate hardware.

6. Standard heaters are mounted in a horizontal position with the ter­minal end on the left.

The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
electric heating equipment. Where the conse­quences of failure could result in personal injury or
property damage, back-up controls are essential.

MOUNTING

1. Locate heater position on wall. This unit has special baffle plates
and vent holes in the cover to ensure sufficient convection currents.
Make sure that the heater is mounted so that the mounting label
located on the end cover points up (Fig. 1).

2. To locate mounting holes, see Specifications Table for heater in
question. In standard 16” stud center frame construction, locate
wall studding and locate 1 upper and 1 lower mounting hole in
center of stud.

3. Drill a pilot hole in metal or wood surfaces using a convenient
small size drill.

4. Drill the 4 holes in accordance with sizes in Table 1. Insert anchors
where applicable.

5. Remove cover screws.

6. Remove cover.

7. Fasten to wall with screws as listed in Table 1. Turn tight and then

back off 1/2 turn, to allow for expansion and contraction.

8. Replace heater cover — fasten with screws and washers removed
in Step 5.
