Reflector, U-Clip and Reflector Support Installation

The pictorial drawings of the heater construction in
Section are schematic only and provide a general
guideline of where hangers, reflector supports and
U-clips are to be installed.
1. The first reflector after the burner must be affixed in
the middle of the reflector with a reflector support and
tight screws.
Reflector
End Cap
U-Clips
Overlap must be a
minimum of 6" (16 cm)
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.

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.
