Read Carefully - These instructions are written to help you

prevent difficulties that might arise during installation of

heaters. Studying the instructions first may save you consid-

erable time and money later. Observe the following proce-

dures and cut your installation time to a minimum.

1. TO REDUCE THE RISK OF FIRE OR ELECTRIC

SHOCK, disconnect all power coming to heater at main

service panel before wiring or servicing.

2. All wiring must be in accordance with the National and

Local Electrical Codes and the heater must be grounded

as a precaution against possible electric shock.

3. Verify the power supply voltage coming to heater match-

es the ratings printed on the heater nameplate before

energizing.

4. This heater is intended for ceiling installation ONLY.

Do not install the heater closer than 12” (305mm) to any

wall for models 548, 542, 547 and 24” (610mm) to any

wall for models 558, 552 and 557.

5. Do not insert or allow foreign objects to enter any ventila-

tion or exhaust opening.

6. Do not block air intakes or exhaust in any manner. Keep

combustible materials, such as crates, drapes, etc., away

from heater.

7. A heater has hot and arcing (sparking) parts inside. Do

not use it in areas where gasoline, paint, or flammable

liquids are stored.

8. This heater is not approved for use in corrosive atmos-

pheres such as marine, green house, or chemical storage

areas.

9. The heater enclosure must be securely mounted to ceil-

ing or framing capable of supporting the heater (45 lbs /

20.4 kg). Failure to do so could allow heater to fall.

10. Do not operate heater without outlet grilles installed.

When installing grilles with louver guides, make sure

guides drop into position so they cannot slide out during

use.
