The pictorial drawings of the heater construction in Section 6 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 depend 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

Slide first reflector after burner a minimum 2” (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

The overlap at the first and second reflector is a slip overlap
