Operation cold air return. This will alow for more efficient heating. Experiment with the placement of the heater to see what works best for you. • To ensure maximum efficiency, a 30% minimum relative humidity should be maintained in the heated environment. • The heater is designed to operate for maximum efficiency in the 68-74 degree range. Due to the soft heat concept, temperatures at 68 degrees F feel as though it were 72 degrees F. This is due to the heat mixing with humidity evenly for head-to-toe comfort. • When the heater is placed in an isolated area, i.e. basement or recreation area, any existing HVAC heating system vents should be closed in that area, if possible. This allows the heater to maintain the isolated area more efficiently. • If placing the heater a few feet above the floor, such in rooms with large areas of bare concrete, make sure the heater is secure and won't fall. This will allow for more efficient heating since concrete acts as a heat sink and will tend to draw the heat in its direction. Optimally, concrete floors should be covered to provide some insulation factor from the concrete. • For zone heating: set your central heating system to a lower temperature. Place the heater in the area you spend the most of your time. Now set the heater to your comfort level. • When heating larger areas, place the heater in a central location. • If the heater is used in an extremely dirty area, the filter must be cleaned more frequently to maintain heater performance.
