2. Frame a rough opening at the desired location—see
earlier sections of this manual for allowable plenum
positions and rough frame opening sizes.
3. Install top mounting bracket(s) to the plenum using
screws provided (3 screws per bracket: use the
short sheet metal screws provided otherwise the
screw tails (ends) will interfere with the fi nishing
frame when installed).
4. Install the plenum(s) into the rough frame opening
maintaining minimum clearances to combustibles as
listed—see page 7. Fix the plenum to the framing
using nails or screws through the top mounting
bracket. Note that the mounting brackets are not
intended to carry the weight of the plenum and
pipes. Provide support to the underside of the
plenum and ensure the plenum is level and its
outlet is not distorted (see detail on page 7). Use
metal strapping (all-round, not supplied) as required
to further secure the plenum to framing.
5. Attach one section of UL-181, Class 1 approved air
duct to each of the collars and secure it with gear
clamps provided. DO NOT SPLICE DUCTS!
6. Attach the top of the pipe sections to the plenum
securing them with the gear clamps provided. An
upward slope must be maintained in horizontal
sections of pipes for proper convection. Use straps
as necessary to maintain the pipes positions.
Support horizontal sections every 24 inches.
7. Paint the inside surfaces of the plenum using high-
temperature fl at black spray paint for installations
where the inside of the plenums may be visible.
Note: The fl anges of the white fi nishing frame
(when used) will insert approximately 1-1/4" into the
plenum covering the shiny sheet metal.
8. Install the fi nishing frame or louver to the plenum
after the wall fi nish is completed:
LDK1, LDK4: Use the LDK2 or LDK5 depending of
the length of the plenum.
LDK3: Use the grilles provided with the kit.
Note: The frame/louver are fi nished white but
may be painted another color if desired; use high
temperature paint (250ºF). You may also fi nish
up to the perimeter of the plenum opening with
your material of choice and not use the frame or
louver. Do not fi nish over any of the opening in
the plenum outlet.
9. Continue with the fi replace installation.
