WARNING: Maintain the minimum clearances. If
you can, provide greater clearances from floor, ceil-
ing, and adjoining wall.
IMPORTANT:
Vent-free heaters add moisture to the air. Although
this is beneficial, installing heater in rooms without enough venti-
lation air may cause mildew to form from too much moisture. See
Air for Combustion and Ventilation, pages 4 through 6.

candles, cleaning fluids, oil or kerosene lamps, etc.)
in the air exist, may discolor walls or cause odors.
