1. Unpack vent components and check all items for shipping
damage.
2. For this venting system to operate as designed it is dependent
on the use of all parts and procedures detailed in these in-
structions. Failure to follow these instructions may potentially
affect the performance of this vent system and the attached
appliance.
3. As per the replace manufacturer’s instructions, replace the
existing 6 5/8” diameter replace vent adapter with the 7”
diameter ex vent replace adapter included in the vent kit.
Install the adapter collar with the screws removed from the
standard replace collar. Refer to the replace manual for ad-
ditional information on the vent collar removal and installa-
tion.
4. Once the replace location has been determined, mark the
ceiling where the ex vent will pass through. Cut an opening
for installation of the restop thimble assembly. The opening
must measure a minimum of 9-1/2” x 9-1/2” square. See Fig-
ure 34.
5. Next, determine the location for the cutout in the roof opening.
This opening must be large enough to provide a minimum 1”
air space clearance from the vertical vent pipe to any combus-
tible framing.
6. Install the Firestop/Thimble assembly to the framed opening
in the ceiling using common nails or screws.
Note: The thimble assembly is adjustable up or down as
needed within the restop. It is also designed with a pivoting
restop for use with 0 - 3/12 pitch cathedral ceilings.
7. To begin vent system assembly, rst layout all the vent com-
ponents on the oor in the order in which they will be assem-
bled.
8. Stretch the 4” diameter inner ex ue and 7” diameter outer
ex vent to the maximum length of 6 feet.
9. Install the spring spacers provided around the 4” diameter ex
ue at 1 foot intervals, then slide the ue pipe with spacers into
the 7” diameter outer ex vent pipe. Make sure the springs are
spaced evenly starting at 12 inches from the replace collar.
