3.5 Gravity Kit Installation
The Clean Face surround comprises no louvers; however, an intake into the chase and an outtake through
gravity ducts is required for this configuration. The instructions below describe the installation of the intake
openings, and the gravity ducts/outtakes. Note that in order to connect the gravity ducts to the sides of the
chase, the sides of the chase need to be constructed and the front of the chase needs to remain open; to
connect the gravity ducts to the front of the chase, the sides need to remain open and the front of the chase
needs to be constructed (Figure 3-24). Please note that the SUPREME KG540 kit and the UCAC8 semi-rigid
insulated ducts are required for the Gravity Kit installation (Figure 3-23).
3.5.1 Dual Louver Gravity Ducts
1.
Determine the two locations of the air intakes on the chase and cut a rectangular opening 10.5” (W) X
9.5” (H). Note that a distance of 5” is required from the floor.
2. Determine the two locations of the air outtakes on the chase and cut
a rectangular opening 10.5” (W) X
9.5” (H). Note that a minimum distance of 64” is required from the floor and a minimum of 6” is required
from the ceiling (Figure 3-40). Please note that the air outtake grilles can be installed in the same room
or in different rooms from each other. If the grilles are installed at different heights, more heat will be
distributed to the highest one.
3. From the exterior of the chase, place the duct/louver adapter into the air outtake hole and secure it onto
the wall with screws. Repeat for the other outtake.
4. Within the chase, place the grooved end of the adjustable 45
o
elbow into the flange of the duct/louver
adapter and secure it using aluminum tape. Repeat for the other outtake.
5. Measure the distance between the duct adapter on top of the unit and the flange of the duct/louver
adapter
and cut the 8” semi-rigid insulated duct (SUPREME part number UCAC8) to the necessary
length. Repeat for the other outtake.
6. Complete the connections by sliding the ducts over the duct adapters and the flanges of the duct/louver
adapters and tighten both ends with the worm gear clamps.
7. From the exterior of the chase, fasten the grilles over the intake and outtake openings with the beige
screws.
