Step 8.9.1 Reflector, U-clip and Reflector Support Installation

The pictorial dra

w

ings of the heater constr

u

ction in 

Section 8

 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.

the middle of the reflector with a reflector support and

tight screws.

Overlap must be a

minimum of 6" (16 cm).

Loose screws

loosened 1/16"

(.16 cm) to allow
