2. If the heater is installed, for your safety, turn off the gas and the electri-
cal power before installing the vertical louvers.
3. Install the Vertical Louver Frame
Position the assembled louver frame in the heater outlet so that the holes in the
tabs on each side are lined up with the holes in the heater. (The tabs fit between
the horizontal louvers.)
Using the screws in the kit, attach the tabs to the sides of the heater outlet.
4. Install the Vertical Louvers in the Louver Frame Using the Compression
Springs (See FIGURE 2.)
Before actually installing the louvers, note the louver curve and determine how
the louvers should be positioned to provide the optimal throw pattern. Depend-
ing on where the heater is installed and 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 2.
a) With the wider section facing out of the heater, place one of the com-
pression 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
either in the top support or the bottom. See FIGURE 2. Slide the tab with
the spring into one of the holes in either the top or bottom support. Push
the louver, compressing the spring enough to place the tab on the other
end into the corresponding hole in the other support.
c) Continue installing the louvers until all vertical louvers are in place.

the heater. Check for proper operation.
1) On the notched end of the
louver, slide the spring over the tab.
2) When facing the unit, for airflow
to the left, push the tab with the spring
into a hole in the top louver frame
(compressing the spring) and insert
the tab on the other end into the
corresponding hole in the bottom.
For airflow to the right, push the tab
with the spring into a hole in the
bottom louver frame (compressing
the spring) and insert the tab on the
other end into the corresponding hole
in the top.
Wider side of the louver
blade must always be
facing out of the heater.
