10. REFLECTOR INSTALLATION
SEM / IT : After burner and tubes have been installed, slide the reflectors one at a time into
the wire hangers. As each successive reflector is installed on an in-line installation, the ends of
the reflectors will overlap to provide continuous coverage over the entire tube system. The
overlapping joints MUST BE FASTENED TOGETHER with a sheet metal screw.
Note that for both horizontal and angle mounting, the tube must be level. Improper mounting
can result in overheating of controls and combustible materials. Use only non-combustible
mounting hardware.
Side reflectors can be added to the heaters as an option. They should be secured directly to the
focus shield reflector using "S" hooks or chain. Drill three holes into the focus shield
reflector flange along side, matching up with three holes already in side reflector. Mount side
reflector as close as possible to the focus shield reflector.

SEMU / ITU : After burner and tubes have been installed, slide the double-wide reflectors
one at a time onto the hangers. Fasten the FIRST hanger nearest the burner to the reflector with
a sheet metal screw up through the hole in the tab at each end of the hanger. Do not fasten any
other hangers to reflectors. SEE FIGURE 5A
