Insert Leveling; Surround Installation - Lennox Hearth Products Winslow PI40 Installation And Operation Manual

The recommended pipe installation is running the pellet pipe
from the insert all the way to the top of the chimney. However,
the pipe may terminate inside the chimney above the damper if
the chimney is sealed below the pellet pipe termination with a
block off panel (see Figure 10). The insert can also be vented
horizontally out the back of the fireplace, but a listed pellet pipe
thimble must be used if the pipe goes through a combustible wall
and the structural integrity of the fireplace and chimney system
must be maintained.

Insert Leveling

Inside the firebox is a bag of hardware with four 4"x 3/8" carriage
bolts. If the insert needs to be leveled, install one of these bolts
(from the bottom side) in the nuts at the left and right rear of the
base of the insert. Open the front door and remove the bolts screwed
into the nuts at the left and right front of the firebox floor.
From the bottom outside of the insert, install the remaining two
carriage bolts in the nuts from which the bolts were just removed.
A zero clearance front support is available to fill the space between
the insert and hearth.
Surround (Flange) Installation
To install the surround panels:
1. Remove the side doors (see Page 24) to access the surround
mounting brackets. Remove the speed nuts from the parts bag
found in the firebox. Install the six speed nuts (with the flat
surface forward) on the six surround mounting bracket holes,
three on each side of the insert. A flat-bladed screwdriver may
help in installing the nuts. See the expanded view in Figure
11A.
2. Screw the six 1/4" truss head screws partially into the speed
nuts (see A in Figure 11A).
3. The side surround panel with the small access door for the
control board goes on the right side of the insert (see Figures
11B and 11C). Slide the slots in the side surround panels and
top surround panels behind the heads of the truss screws.
Tighten all six truss screws after shifting surround panels to
eliminate space between the side and top surround panels.
4. Install two spring clips approximately five inches from each
end of each of the three trim pieces. The spring clips should be
installed in the channel of the trim with the curved portion of
the clip to the front toward the rounded surface of the trim.
5. Place the longest trim piece with the rounded surface out along
the edge of the top surround panel with the spring clips slightly
behind the surround panel. Pull the trim forward, compressing
the spring clips, and slide the trim down onto the surround.
6. Insert the elbowed retainer in the mitred end of the side trim
pieces and fasten with flat screwdriver. Insert the other end
of the retainer in the end of the already installed top surround
trim and slide side trim onto the edge of the side surround
compressing the spring clips in the process. Repeat the same
steps for the other side trim. Fasten the elbowed retainer
securely in the top surround making a nice mitred corner.

*The block off panel should be
air tight to ensure smoke does
not enter the house and to help
establish chimney draft when the
pipe does not terminate at the top
of the chimney.
