NOTE: Do not install
louvers if installing
a nozzle. Follow the
instructions shipped with
the nozzle.
Louver Installation Instructions:
1) 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.
2) Depending on the throw 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.
3) Continue until all louvers are installed.
Adjust the louvers to provide the
desired throw pattern.

6.2.1 Installing
Louvers
After the unit is suspended/mounted, install the air directional louvers or
optional nozzle. If an optional nozzle is being installed, follow the instructions
included with the nozzle. If a nozzle is not being used, install the louvers in
the discharge opening(s). Louvers and springs are in the hardware kit shipped
with the heater.
Before actually installing the louvers, note the louver curve and determine how
the louvers should be positioned to provide the optimal throw pattern. Opening
is square so louvers may be installed either horizontal or vertical. 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 8.

the coverage area.
