THERMOSTAT SENSING BULB The thermostat sensing bulb is located on the lower rear panel of heater.

1.Place clamp on thermostat sensing bulb as shown in Figure 5. Clamp is provided in hardware package.

2.Snap clamp into mounting hole as shown in Figure 5. Mounting hole is located in the center of lower back panel of heater. Make sure the thermostat sensing bulb is horizontal.

CAUTION:Thisheatercreates warmaircurrents.Thesecurrents move heat to wall surfaces next to heater. Installing heater next to vinyl or cloth wall coverings or operating heater where impu- rities (such as, but not limited to, tobaccosmoke,aromaticcandles, cleaning fluids, oil or kerosene lamps, etc.) in the air exist, may discolor walls or cause odors.

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 Air for Combustion and Ventilation, page 5. If high humid- ity is experienced, a dehumidifier may be used to help lower the water vapor content in the air.

INSTALLING HEATER TO WALL

Methods For Attaching Heater To Wall Attach heater to wall in one of two ways:

1.Attaching to wall stud

2.Attaching to wall anchor

Attaching to Wall Stud: This method provides the strongest hold. Insert mounting screws into wall studs.

Attaching to Wall Anchor: This method allows you to attach mounting screws to hollow walls (wall areas between studs) or to solid walls (concrete or masonry).
