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 /

When installing grilles with louver guides, make sure
