Step 7.8.1 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.

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
