CAUTION
This heater creates warm air currents. These currents move heat
to wall surfaces next to heater. Installing heater next to vinyl or
cloth wall coverings or operating heater where impurities in the air
(such as tobacco smoke) exist, may discolor walls.
IMPORTANT:
Vent-free heaters add moisture to the air. Although this is beneficial,
installing heater in rooms without enough ventilation air may cause mildew to form
from too much moisture. See Fresh Air for Combustion and Ventilation, pages 5
through 8.
