ates warm air currents. These cur-
rents move heat to wall surfaces
next to heater. Installing heater
next to vinyl or cloth wall cover-
ings or operating heater where
impurities (such as tobacco
smoke, aromatic candles, oil or
kerosene lamps, etc.) in the air
exist, may discolor walls.
IMPORTANT:
Vent-free heaters add mois-
ture 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 Air for Com-
bustion and Ventilation, pages 4 through 6.
NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your pri-
mary heating system. Do not in-
stall this heater as your primary
heat source. If you have a central
heating system, you may run
system’s circulating blower while
using heater. This will help circu-
late the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
