mable objects are less than 36 inches from the

coverings or operating heater where impurities (such
as but not limited to, tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene lamps, etc.) in the air
exist, may discolor walls or cause odors.

though this is beneficial, installing heater in rooms without enough
ventilation air may cause mildew to form from too much moisture.
