Elbow Package Installation
(P/N 02718702) Elbow Package includes: (1) elbow, (1)
coupling, (1) end cap, (1) reflector joint piece, and (1)
package of U-Clips. Install elbow into radiant tube
sequence where plans indicate a 90° bend. Install
reflector joint piece using the following procedure:
1. Flatten reflector edge where joint piece matches. Put a
mark on the reflector, directly over the tube center.
Center the accessory joint piece on the mark and
scribe its contour on the reflector. Scribe the location
of the mounting holes.
2. Cut away the reflector to clear the tube, leaving about
one inch of material inside the scribed contour to
attach the accessory joint. Drill or punch six 3/32" (2
mm) diameter holes in reflector in the positions shown
in Figure 13.
3. Use six #10 sheet metal screws to attach the joint
piece. Install a reflector end cap of the open end.

Reflector End Cap Installation
Reflector end caps must be installed over the open ends
of reflectors. Attach the end cap to the reflector using a
minimum of four U-clips per end cap.
Before installing the end cap, the center section must be
removed. Carefully break the tabs on the bottom flange of
the end cap first. Then gently flex the center section until
it releases. Be very careful not to distort or otherwise
damage the end cap during this procedure.
If the end cap is used at a joint piece to cover a 90° elbow
or U-tube, the center section should not be removed.
