IMPORTANT !

CAUTION !

CERTAIN FABRICS DISCOLOR IN TIME FROM INDIRECT SUNLIGHT AND NORMAL ROOM TEMPERATURE - MOSTLY ORGANIC AND SYNTHETIC MATERIAL. THEY WILL DISCOLOR MORE RAPIDLY WHEN EXPOSED TO DIRECT SUNLIGHT AND WARM CURRENTS. HANG DRAPES TO PROVIDE MINIMUM OF 2 INCHES (51mm) AIR SPACE BETWEEN HEATER FRONT

CAUTION !

HEATER MAY BE INSTALLED ABOVE THE FLOOR SUCH AS ATOP A BASE- BOARD. HOWEVER, THE POWER SUPPLY MUST ENTER THE HEATER THROUGH THE KNOCKOUT IN THE BACK OF THE HEATER IF INSTALLED ABOVE THE FLOOR.

AND NEAREST DRAPE FOLD AS SHOWN IN EXAMPLE 1, FIGURE 1, OR 6 INCHES (152mm) AIR SPACE BETWEEN TOP OF HEATER AND BOTTOM

OF DRAPES AS SHOWN IN EXAMPLE 2, FIGURE 1. ALLOW MINIMUM CLEARANCE OF 1 INCH (25mm) FROM DRAPES TO CEILING AND TO TOP

OF FLOOR COVERING TO PERMIT AIR CIRCULATION.

CAUTION !

TO PREVENT POSSIBLE DAMAGE TO INTERNAL HEATER WIRING, ALL DRILLING OF END CAPS MUST BE DONE WITH END CAPS REMOVED FROM HEATER.

CLEARANCES

FLOORS & CARPETING: HEATERS MAY BE MOUNTED DIRECTLY ON ANY FLOOR SURFACE, INCLUDING CARPETING. WHERE WALL-TO-WALL CAR-

PETS ARE INSTALLED AFTER THE BASEBOARD INSTALLATION, THE CAR- PETING CAN BE RUN UP TO THE FRONT AND AROUND THE HEATER BODY.

FULL LENGTH DRAPES: FOR THE MOST SATISFACTORY OPERATION OF HEATERS, THE FOLLOWING CLEARANCES MUST BE MAINTAINED:

1.HANG DRAPES SO THAT, IN USE, THEY EXTEND BELOW THE CENTER LINE OF THE HEATER, BUT WITH AT LEAST 1” (25mm) CLEARANCE FROM THE TOP OF THE FINISHED FLOOR COVERING, SUCH AS CARPET, TILE, ETC.

2.HANG DRAPES SO THERE IS AT LEAST 2” (51mm) BETWEEN THE EXTREME FRONT OF THE HEATER AND THE NEAREST FOLD OF DRAPES, IN THE FOLDED BACK POSITION (OPEN DRAPE POSITION).

3.HANG DRAPES SO THERE IS AT LEAST 1” (25mm) BETWEEN THE TOP OF THE DRAPES AND THE CEILING.

SHORT DRAPES: HANG DRAPES SO THERE IS AT LEAST 6” (152mm) CLEAR-

ANCE ABOVE THE TOP OF THE HEATER.

FURNITURE: DO NOT PLACE FURNITURE AGAINST HEATER. IT IS RECOM- MENDED ALL ITEMS BE KEPT A MINIMUM OF 6” (152mm) FROM HEATER.

INSTALLATION OF SINGLE UNIT

Liquid filled baseboard heaters are designed for installation in new or existing con- struction. In existing construction, baseboard molding should be removed and the heaters mounted flush against the wall surface. When replacing molding allow 1/16” (1 mm) clearance between molding and ends of heaters.

NOTE: This heater can be wired in either the right or left hand junction box. See Table 1 for wiring compartment volumes.

Figure 2. Installation of Heater

1. Position the heater at the desired location on the wall as shown in Figure 2. For maximum heating comfort, position the heater under a window.

2. Mark the location on the wall or floor for the power supply entry into the heater. Remove the heater from the wall and drill appropriate hole in the wall or floor.

3. Remove the left or right junction box end cap by removing the screw in the end of the heater and sliding the cap outward from the heater (Figure 3).

4. Remove the front cover of the heater by removing the screws in the lower cor- ners. Pull the bottom of the cover outward and lift the top of the cover off the junction box. Repeat for the opposite end. Snap the top of the cover off the cen- ter bracket and off the intermediate supports. See Figure 4.

5. Remove the appropriate electrical knockout from the back of the heater or accessory if necessary. Supply wiring may also enter the raceway through the floor or wall without using a knockout.
