Reflector, U-Clip and Reflector Support Installation
The pictorial drawings of the heater construction in
this Section are schematic only and provide a gen-
eral guideline of where hangers, reflector supports
and U-clips are to be installed.
To ensure proper expansion and contraction move-
ment of the reflectors, a combination of U-clips and
reflector supports are used. The positioning of reflec-
tor 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.
