Step 6.5.1 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. 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.
