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 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 CARPETS ARE INSTALLED AFTER THE BASEBOARD INSTALLATION, THE CARPETING 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) CLEARANCE ABOVE THE TOP OF THE HEATER.
FURNITURE: DO NOT PLACE FURNITURE AGAINST HEATER. IT IS RECOMMENDED 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 construction. 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.

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 corners. 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 center bracket and off the intermediate supports. See Figure 4.
