Figure 10. Installation of Duct Connector
INSTALL FURNACE MOUNTING PLATE
a. Bend tabs on furnace mounting plate
upwards 90 °
b. Place mounting plate (supplied within
duct connector) at rear of the floor
opening (See Figure 8).
INSTALL DUCT CONNECTOR
e. Place duct connector through the floor
opening with bottom tabs extending
through the duct opening. (See Figure 9)
b. Secure duct connector to floor.
c. Bend bottom tabs under and up tightly
against the supply air duct (See Figure
10).
NOTE: The duct connector is designed for
use on ducts 12" in width. When using the
connector on 12" wide ducts, there may be
insufficient clearance to bend the tabs on two
sides of the duct connector. In such cases the
tabs may be attached to the sides of the duct
by using sheet metal screws or other suitable
fasteners. (See Figure 11).
if ial_e is used to provide a better seal, it should
be approved by applicable national or local codes.
ALTERNATE ATTACHMENT METHODS
This procedure may also be used to install a
furnace duct connector to narrow metal
ductwork where insufficient clearance prevents
bending of the duct connector tabs at the
side(s) of the duct. (See Figure 12).
1. Score and cut the top of the metal duct as
indicated in Step 1 or Step 2. With Step 1
choice, also cut out the metal from the
shaded area "A".
2. Fold the duct flap "B" up, (See Step 3).
3. At the front-to-back of duct run (Area
"A"), bend the duct tabs and secure them
directly to the duct.
