4. Install the tube downstream of the "L" tube. The downstream tube adjacent to
the "L" tube requires two suspension points. Attach two tube brackets to the tube
( FIGURE 3). Attach the wire reflector retainers. Suspend from the hanger bar in
both locations.
FIGURE 2 - Use the
coupling to connect
the "L" tube.
Follow the instructions in the heater installation manual for inserting turbulator
strips.
3. Connect the "L" Tube - Use the compression coupling in the kit to attach the "L"
tube following the same procedure as the straight tubes.
Installation
Instructions (cont'd)

2nd, Insert Self-Drilling Screws
FIGURE 3 - Bottom view
of the downstream
heat exchanger tube
adjacent to the "L"
tube. Attach two tube
brackets and wire
reflector retainers.
Suspend from the
hanger bar in both
locations.
5. Following the layout, suspend and connect the remainder of the tubes according
to the instructions in the heater installation manual. The tubes adjacent to the "L"
must be at right angles. All tubes must be level.
6. Install Straight Reflectors between the Burner/Control Box and the "L" Tube
- Starting at the burner/control box, follow the instructions in the heater installation
manual to install the straight reflectors before the "L" tube. Be sure to comply with
all requirements.
 Leave 1/4" (6mm) space between the first reflector and the burner/control box.
 Use screws to attach the first reflector section to the first tube bracket
 Use clips and screws to join reflectors
7. Assemble "L" Tube Reflector - Assemble the reflector top and sides and attach
the reflector bracket as illustrated in FIGURE 4.
NOTE: Before
installation, wipe any
excess corrosion inhibitor
from the heat exchanger
tubes. Failure to do so
could result in excessive
smoke from the surface
of the tubes on initial
startup.
