Installing the Duct Connector
1.
Attach the four (seal strip) foam tape gaskets provided
with the duct connector alongside the perimeter of the
duct opening to seal the duct connector where it attaches
to the top of the duct as shown in Figures 7, 8 and 9.
2.
Insert the duct connector thru the opening in the floor and
attach the duct connector to the top of the duct by
inserting the tabs thru the opening in the top of the duct
and bending the tabs back 90 degrees against the inside of
the duct, so the top of the duct is securely fastened to the
duct connector. Be sure the seal strip has sealed the area
around the duct connector where it attaches to the duct.
3.
Slit the corners of the duct connector that extend above
the floor, and then bend the sides over onto the floor
surface. Refer to Figures 7, 8 and 9.
4.
It is recommended to place insulation with a rating of R-
12 or higher between the floor base and the floor when
used on a combustible floor. The use of insulation
between the duct connector and a combustible floor is not
a requirement, it is a precautionary measure to guard
against the combustible floor from getting to warm. If
insulation is used, be sure to cut the insulation around the
perimeter of the duct connector opening.
5.
Install the floor base over the floor opening with the
flanges on the 11 x 13 inch opening facing down. Refer to
Figures 8 and 9.
6.
Locate the four (4) screws provided with the duct
connector kit and install the four screws through the four
holes provided in the floor base to secure the floor base to
the floor.
The duct connector is designed for use on ducts wider than 12
inches. When using the connector on smaller width ducts,
there will not be sufficient clearance to bend the tabs on two
sides of the duct connector. This furnace is designed to be
installed on an existing 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. Place
holes in the tabs for sheet metal screws by drilling the required
screw holes in three (3) tabs on each side of the duct
connector. If more than three tabs need to be used to provide a
more secure and air tight connection, then drill the remaining
tabs so the additional tabs can also be fastened to the duct with
screws. Use a duct sealer to seal any air leaks between the duct
and the duct connector.
Tape can be used to provide a better air seal. The tape should
be a type approved by applicable national or local codes.
