Side Shield
Installation
Instructions
Because side shields can be installed anywhere along the tube length and
use the same wire reflector retainers and tube brackets as the tubes, the side
shield hanger slots must be made in the field to match the system. Therefore,
the first hanger slot location is shown in FIGURE 20. After the first section is
installed, determine the location of each hanger slot and drill and cut hanger
slots one section at a time.
1) Side shields are designed with a 3/4” (19mm) overlap. On the first sec-
tion, on the top edge with the 60° bend, measure in 3/8” (9.5mm) and 7/8”
(22.2mm) from the end and 21/32” (16.7mm) from the bend. Drill two 5/16”
(8mm) holes. Cut out the material between the two holes to form a slot.
Repeat on the opposite end.

section.
IMPORTANT:
•
Install side shield on one
side of the system only.
•
Maximum reflector angle
with a side shield is 30°.
•
If angled, hang side shield
on lower side only. Do not
hang a side shield on the
higher side.
2) Starting at the already installed reflector retainer/bracket at the burner box
(or wherever the side shield is being placed), determine where the next
side shield hanger is needed. At that location, install one of the wire reflec-
tor retainers and a tube bracket supplied with the side shield. NOTE: Sus-
pension is not required at any of the additional wire reflector retainers and
tube brackets installed to support side shields.
3) Hang the first side shield section from the ends of the two wire reflector
retainers. To secure the side shield, slide the round clip over the ends of
the wire until it contacts the side shield.
4) Repeat the process until all side shield sections are installed. To adapt to
tube suspension points, a side shield may require more than two hanger
slots.
The optional end covers are designed to “close” the vertical space on both the
burner/control box end and the exhaust end of the reflector length.
Install following the illustrated instructions included in the option package.

Reflectors may be angled up to 45°. Angling the reflector is accomplished by
moving the position of the “S” hook on the hanger bar. The hanger bar has
three holes left and right of the center hole. Moving the “S” hook to the first hole
from center will rotate the reflector 15°; the second hole 30°; and the third hole
45°. Refer to FIGURE 22 and comply with the requirements and instructions
below.
• All reflectors in a system must be at the same angle.
• Reflectors on straight systems without a side shield may be angled 15°,
30°, or 45°; see FIGURE 22.
