Step 6.6.1 Reflector, U-Clip and Reflector Support Installation
The pictorial dra w ings of the heater constr u ction in
Section 6 are schematic only and pro v ide a general
g u ideline of w here hangers, reflector s u pports and
U-clips are to be installed.
To ens u re proper expansion and contraction mo v ement of
the reflectors, a combination of U-clips and reflector
s u pports are u sed. The positioning of reflector s u pports
and U-clips depend on the indi v id u al installation. Use
either pop ri v ets or sheet metal scre w s instead of U-clips
w hen installing end caps and joint pieces in areas w here
impact and high w ind may be a factor.The follo w ing r u les
m u st be obser v ed:
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.
