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.
(1) Attach nozzle sides
inside heater outlet
with 3/8” screws.
(2) Attach nozzle top
and bottom with 1/2”
self-drilling screws.
