Step 8.9.1 Reflector, U-clip and Reflector Support Installation
The pictorial dra
w
ings of the heater constr
u
ction in
are schematic only and provide 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
movement 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
individ
u
al installation. Use either pop rivets 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

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.
