Step 6.6.1 Reflector, U-Clip, and Reflector Support Installation
The drawings of the heater construction in “SECTION 6: HEATER INSTALLATION” on page 12 are schematic
only and provide a general guideline of where hangers, reflector supports, and U-clips are to be installed. To
ensure proper expansion and contraction movement of the reflectors, a combination of U-clips and reflector
supports are used. The positioning of reflector supports and U-clips depends on the individual installation. Use
either pop rivets or sheet metal screws instead of U-clips when installing end caps and joint pieces in areas
where impact and high wind may be a factor. The following rules must be observed.
1. Slide first reflector after burner a minimum of 2 in. (4 cm) through first hanger and ensure reflector end cap is
securely fastened via U-clips, pop rivets, or sheet metal screws. Position reflector support with tight screws
in middle of first reflector.
2. The overlap at the first and second reflector is a
slip
overlap
. Thereafter, every third reflector joint is a slip
overlap. A slip overlap is achieved by either:
a. Both reflectors lay inside a hanger. (No reflector
support needed.)
b. Using a reflector support with loose screws at the
reflector overlap.
3. The remaining reflector overlaps require a
non-slip
overlap
connection. To affix the reflectors together in a
non-slip overlap, either:
a. Use reflector support and tight screws.
b. If both reflectors lay inside a hanger, U-Clips or
sheet metal screws may be used.
This section of three reflectors joined together must be
affixed to the tube with at least one reflector support with
tight screws.
