Installation
WARNING: Improper installation, adjustment, alteration, service, or
maintenance can cause property damage, injury or death. Read the
Instructions
installation, operation, and maintenance instructions thoroughly before
installing or servicing this equipment.
Installation should be done by a qualified agency in accordance with the instructions on this sheet and in compliance with all codes and requirements of authorities having jurisdiction.
n Option CD57 or CD58 ...... Follow instructions in SECTION A.
n Option CD59 .......................Follow instructions in both SECTIONS A and B.
All installations will also include the louvers that were shipped with the heater. Repeat the instructions to install a
nozzle on each heat section.
SECTION A
1. If the heater is installed, turn off the gas and the electric power.

3. If the louvers shipped with the heater have been installed in the heater discharge opening, remove them.
Save the louvers and the springs to be re-installed in the nozzle discharge.
4. Install the Assembled Nozzle in the Heater Outlet (FIGURE 4)
All Options - The discharge opening is square so the nozzle can be installed in any direction. Determine the
appropriate direction and position the assembled nozzle in the heater outlet so that the holes on each side are
lined up with the holes in the heater. Use the 3/8” screws in the kit to attach the nozzle sides to the heater.
Screw ends should be inside the nozzle.

2. Assemble Nozzle
All Options - See FIGURE 2. Assemble a nozzle section. Use the 3/8” screws in
the kit to attach both sides to the top. Attach the bottom to both sides.
Options CD57 and CD58 - Use 3/8” screws to attach side fillers as shown.
Option CD59 - Do not attach side fillers; save to install later.

Using the 1/2” self-drilling
screws in the kit, reach
inside the nozzle and
attach the nozzle top and
bottom to the heater outlet.
Use the holes in the nozzle
top and bottom to position
the screws.
(2) Attach nozzle top
and bottom with 1/2
self-drilling screws.
(1) Attach nozzle sides
inside heater outlet
with 3/8 screws.
5. Install the Louvers in the Nozzle Outlet
All Options - Before actually installing the louvers, note the louver curve and determine how the louvers
should be positioned to provide the optimal throw pattern. Louvers may be installed with the curve all the
same direction (either way) or the right half one way and left the other as illustrated in FIGURE 5. Follow
the instructions and refer to the illustration to install the louvers using the compression springs.
Louver Installation Instructions:
a) With the wider section of the louver facing out of the heater, place one of the compression springs over
the tab on the notched end of a louver. The end of the louver with the spring will fit in any direction in
the square opening. How the louver turns depends on which end of the louver is inserted first.
b) Depending on the airflow pattern selected, push the louver tab with the spring into a hole in the discharge
opening and insert the louver tab on the other end into the corresponding hole on the opposite side.
c) Continue installing until all louvers are in place. Adjust the louvers to provide the desired air throw
pattern.

2. Install the Assembled Louver Frame in
the Nozzle Outlet (See FIGURE 7.
Note that standard louvers are not
shown but should already be installed
in the nozzle.)
Position the assembled louver frame in
the nozzle outlet so that the holes in the
tabs on each side are lined up with the
holes in the nozzle. The tabs in the louver frame fit between the louvers already
installed in the nozzle discharge. Using
the 3/8” screws (P/N 195638) from the
kit, attach the louver frame tabs to the
nozzle. Screw ends should be inside the
nozzle.
Use the 1/2” self-drilling screws (P/N
195249) to attach the other two sides of
the louver frame. Use the holes in the
louver frame as a template for inserting
the screws.

3. Install the Louvers in the Louver Frame Using the Compression Springs
(See FIGURE 8.)
Before actually installing the louvers, note the louver curve and determine
how the louvers should be positioned to provide the optimal throw pattern.
Depending on the desired direction of airflow, louvers may be installed with
the curve all the same direction (either way) or the right half one way and the
left the other as illustrated in FIGURE 5, page 3.
a) With the wider section facing out of the heater, place one of the compres-
sion springs over the tab on the notched end of the louver.
b) Depending on the throw pattern selected, the end with the spring can go in
either direction. Slide the tab with the spring into one of the holes in either
of the sides. Push the louver, compressing the spring enough to place the
tab on the other end into the corresponding hole in the other side.
c) Continue installing until all louvers are in place.
4. Adjust the louvers to provide the desired throw pattern.
CAUTION: To avoid getting burned, adjust louvers while heater is
not in operation. If louvers are adjusted while heater is in operation,
wear protective gloves.
5. Repeat nozzle installation as required for each heat section. If the heater is in-
stalled, turn on the electric and the gas. Light the heater following the lighting
instructions. Check for proper operation.
