INSTALLATION INSTRUCTIONS
1. Wall
Preparation:
To prevent excessive heat loss through the walls in back
of BASE-RAY
®
, it is recommended that the stud space
behind the Assemblies be insulated to a height of at least
12” above the
À
oor with 4” mineral wool batts (blanket
or loose insulation may also be used) or other approved
insulating materials. This is particularly essential if the
BASE-RAY is recessed. Mark Stud locations.
2. Allowance for Finished Flooring to Wall-to-Wall
Carpeting:
If BASE-RAY is to be installed prior to the
¿
nished
À
oor,
a wooden strip 2½” in width and equal in height to the
¿
nished
À
oor should be installed along the base of all walls
where baseboard assemblies and trim are to be placed.
If allowance is not made for wall-to-wall carpeting, or for
carpeting that is to be laid with edges
À
ush to the room
side surface of BASE-RAY, the air inlet of the BASE-
RAY will be restricted, resulting in a reduction in output.
To compensate for the wall-to-wall carpeting, baseboard
assemblies and trim should be raised by laying under them
a strip of wood 2½” wide and the same thickness as the
carpet and pad.
3. Recessing of BASE-RAY Assemblies and Trim.
(If BASE-RAY to be installed free-standing, proceed to
Step
4.)
BASE-RAY and Trim may be partially recessed or installed
free standing against the
¿
nished wall surface. Although
procedure for preparing recess may vary slightly with type
of
¿
nished wall, in general, steps outlined below for lath
and plaster construction may be followed:
a. Nail ½” plaster ground to studs with the bottom of
the plaster ground located 10” above
¿
nished
À
oor.
* Additional height must be allowed if recess
prepared
before
¿
nished
À
oor is laid or if wall-to-
wall carpeting is to be installed – see Step 2 of
Installation
Instructions.
b. Line back of recess with paper-backed aluminum
foil. This can be accomplished quickly and neatly
by stapling foil to studs with staple gun. Foil
surface should be on room side.
4. Locate Holes for Piping (see Illustrations):
