Please read specification label on product for further information and requirements. PLAN THE INSTALLATION This heater is designed for installation in an enclosed space such as under a counter or kickspace to provide warm, gentle heat at the floor level. Reread Safety Notes 3 through 8 for guidelines in planning the installation. The Model 114 is factory wired for 240/208 V.A.C. operation. It offers a choice of heat outputs and can be internally connected for multiple wattages at different voltages shown in the table below. VOLTS WATTS AMPS BTU/HR 240 1500 6.3 5120 208 1125 5.4 3840 120* 1500 12.5 5120 120* 750 6.3 2560 All ratings are 1-Phase, 60 Hertz. *See “FIELD CONVERSION TO 120 V.A.C.” section. INSTALL THE HEATER 1. Mark the intended mounting location in the base plate under the counter or kickspace, and remove required material to provide for easy insertion and removal of the heater cabinet. SIDE ANGLE SUPPORT BRACKETS 2.The unit will be secured in place with screws through the side angle support brackets. Provide adequate material behind side angle support for secure mounting. Installer: Leave this manual with the homeowner. Homeowner: Use and Care information on page 3. 4 ® FIELD CONVERSION TO 120 V.A.C. If a 120 V.A.C. circuit is to be used, make wiring changes as follows: 1. Disconnect white wire from heater element terminal “2” and connect it to terminal “4.” The heater will now operate at 120 V.A.C., 750W, 6.3A. 2. For 120 V.A.C, 1500W, 12.5A operation, add the short red jumper wire (provided) between terminals “1” and “2”. 3. Remove alarm light wire leads from terminals “1” and “3” of the high temperature limit. Remove white wire lead from limit terminal “1” and reconnect at limit terminal “3”. Secure wire leads with wire tie so there is no interference with unit operation. NOTE: Terminal numbers are marked on the side of the blower housing, above the heater elements. THERMOSTAT INSTALLATION NOTE: The thermostat control circuit must be wired prior to the wiring of the heater unit. This heater may be thermostatically controlled by either a line voltage wall-mounted thermostat (Model 86W), or an optional built-in thermostat accessory kit (Model 90). Model 90 thermostat kits are designed for easy installation with this heater. Instructions for installing thermostats are provided below and are also supplied with each thermostat kit. Page 2 THERMOSTAT INSTALLATION OPTIONAL LINE VOLTAGE WALL-MOUNT THERMOSTAT 1.Locate thermostat on an inside wall away from all drafts and approximately 4-5 feet above the floor. 2.Route all wiring through the thermostat first and then to the heater. OPTIONAL (MODEL 90) UNIT-MOUNT THERMOSTAT 1. Remove the top cover from the heater. 2. Remove the 5/8” knockout located on the left side of the front panel (use a screwdriver to remove the knockout). Also remove the two plastic hole plugs (see illustration). 3. Install thermostat from back side of front panel and fasten in place, from front, with two screws and washers provided (see illustrations). 4. Attach temperature control knob by gently pushing it on to the thermostat shaft. Flats on shaft and knob must line up for proper installation (do not force control knob onto shaft). 5. Remove black wire from thermal fuse and attach it to thermostat terminal marked “4”. 6. Remove white wire from temperature limit terminal marked “1” (Note: the other end of this wire is attached to incoming field wiring) and attach it to the thermostat terminal marked “1”. 7. Attach black thermostat wire to thermal fuse and white thermostat wi...
