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. Use 
either pop rivets or sheet metal screws instead of u-clips 
when installing end caps and joint pieces in areas where 
impact and high wind may be a factor. 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.
