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
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:
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.
