Reznor PXH Option - Installation - Downturn Nozzle Installation - Indoor PreevA - Manual (Page 2)

Form I-PREEVA-DN, P/N212184R2, Page 2
Instructions 1. If the heater is installed, turn off the gas (PDH, SDH, SHH). Turn off the power.
2. Assemble Downturn Nozzle Section(s) - See FIGURE 2.
Using the screws in the kit, attach both sides to a top. Attach a bottom to both
sides. If installing a Size that requires a center support (see component list), attach
the center support.
If installing Option CD3 or CD5, use the second set of nozzle parts and
assemble the second nozzle section. (The second section assembled will not have
a center support.)
3. Install Assembled Downturn Nozzle Section(s) - See FIGURE 3.
If there are two assembled nozzle sections, select the one without the center
support. Position that nozzle section in the heater outlet so that the holes on each
side are lined up with the holes in the heater.
Using the screws in the kit, attach the nozzle section to the heater outlet.
If installing Option CD3 or CD5, position the second assembled nozzle in the
outlet of the nozzle already attached to the heater. Attach the second nozzle to the
first nozzle creating a downturn with two sections.
4. Install the Horizontal Louvers in the Nozzle Outlet - See FIGURE 3.
a) With the wider side of the louver facing out of the heater, place one of the
compression springs over the tab on the notched end of the louver.
b) Slide the tab with the spring into one of the holes on the left side of the opening
(left when facing the heater). Push the louver, compressing the spring enough
to place the tab on the other end into the corresponding hole on the right (either
on the side of the outlet or in the center support).
c) Continue installing the louvers until all horizontal louvers are in place.
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.
