Next, locate the center top surround section and install four
¼”-20 x ¾” socket threaded studs into the holes shown
below using a 1/8” allen wrench. Figure 5.7.
Figure 5.8
Slide the center surround section onto the mounting frame
and install a ¼” washer and then a ¼” nut onto each of the
four studs. These nuts should remain loose until the entire
surround has been installed and adjusted. Figure 5.8.
Align the top center surround section between the right and
left panels and tighten the four ¼” nuts to lock it in place.
Now tighten the 3 bolts and nuts on the left and right side
panels.
Unbolt the mounting frame from the shipping pallet using a
½” socket on the three lag screws; the lag screws and the
pallet will not be reused and can be discarded.
Install the outside air pipe stub [if used], to the mounting
frame. Figure 5.9.
There are two different flue pipe stubs available. The unit
comes standard with the largest pipe stub.
1. Part #1-00-574034 is for use with 4” PL vent starter pipe
and 4” stainless steel flex pipe (Part #1-00-574034).
2. Part #1-00-674039 is for use with 3” PL vent starter pipe
and also for use with 3” aluminum flex duct for outside air
connections.
The flue stub assembly base is a round plate which allows it
to swivel to allow the flue pipe to exit the mounting frame in
other positions rather than straight up. Figure 5.10.

Installing Power Cord
The power cord can be installed exiting the left (standard)
or right side of the surround. If a right side cord is desired,
follow the instructions below.
The cord is located on the left side, standard from Harman®.
To route the cord to the right side:
1. Cut the wire-ties looping the cord to the left. Figure 5.11.
2. Re-route the cord along the top of the steel angle and
down the right side.
3. Re-tie (not supplied by Harman®) the wire through the
notches provided in the mounting frame. Then down the
right side rail.
4. Do not remove the cord retainer, it is made to reach both
the right and left sides.
NOTE:
The cord retainer MUST BE installed prior to installing
a wing extension.

Figure 5.9
With the three wing pieces installed, the cord retainer must be
bolted to the bottom rear of the wing. Either left exit (shown
in Figure 5.12) or right exit.
At the bottom rear edge of the right and left wing there is a
small radius indent for the cord to exit between the wing and
the fireplace face.
NOTE:
If installing the optional wing extension it must be
installed before completing the following steps.
With the surround attached and the power cord installed,
install the coupler nut weldments to the frame in the hole
location that suits your needs with the (4) 1/4-20 x 5/8 flange
screws and nuts and 1/2” jack bolts. Install the (4) 5/16”-
18 leveling bolts into the threaded holes in the bottom pan
of the mounting frame, install the mounting frame into the
opening and adjust these bolts to insure the frame is level.
(
NOTE:
Use of all 4 leveling bolts may not be necessary.)
Tighten the ½” jack bolts against the lintel. See Figure 5.13.
