Step 6.4.3 Reflector, U-clip and Reflector Support Installation
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
1. The first reflector after the burner must be affixed in
the middle of the reflector with a reflector support and
tight screws.
Reflector
End Cap
U-clips
Overlap must be a
minimum of 160 mm
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.

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
