LC SERIES 18 GAUGE SLOPE TOP BASEBOARD
LC-850 and LC-1400 do not have a backpanel. One piece wall mounting
bracket/element holder is ordered separately from cover, therefore bracket spacing
is determined by system design and installation. The small vertical lip at the bottom
of the front cover is where the installer drills a small hole to screw the front cover to
the brackets. LC series is ideal for use in replacement applications where you want
to use the existing, installed element and just replace the co ver. Output ratings are
the same as HD series. Contact Slant/Fin for more detailed information.

* Based on 65˚F entering air temperature. † Millinches per foot.
Note: Ratings are based on active finned length (3" less than overall length), and include 15% heating effect factor. Use 4 GPM rating only when flow is known to be
equal to or greater than 4 GPM; otherwise 1 GPM ratings must be used.
