Method E
1.
Apply a bead of caulking, mastic, or other
approved sealant around bottom side of 1/2”
flange and restrictor plate, when applicable.
2.
Locate the duct connector over duct and
carefully lower screw down duct connec-
tor into place.
3.
Once duct connector is located on duct,
temporarily hold in place while fastening
duct connector to the floor using flat head
screws or nails. Be sure flanges of duct
connector stay in contact with the duct.
4.
Screw duct connector to duct making sure
a seal is made between the duct and the
duct connector. Additional screws may be
added if required.
5.
Cut away duct along edge of duct connec-
tor flange allowing the center to drop into the
duct. Remove section of duct with caution,
as edges will be sharp.
Alcove Installation
1.
Cut alcove rough openings to minimum
dimensions shown in Figure 13.
2.
Attach frame assembly with four fasteners
(provided or equivalent) into pre-punched
holes on top of furnace (see Figure 5).
3.
At manufacturers discretion, if additional
securement is required attach each side of
frame assembly to alcove opening using
holes provided.
2.
Fold the duct flap “B” up (see Figure 12,
Step 3).
3.
At the front-to-back of duct run (see Figure
12, area “A”), bend the duct connector tabs
and secure them directly to the duct.
4.
At area “B”, bend the duct connector tabs
up and back over, around the duct connec-
tor (see Figure 12, step 3).
5.
Fold/form the duct flap against the side of
the duct connector and attach as shown
(see Figure 12, Step 4). Use at least three
staples on each duct flap OR... if a 2X block/
joist is not provided, use at least two sheet
metal fasteners on each duct flap.
6.
Seal the duct flap edges with an approved
tape or compound for a leak-free joint.
