CAUTION: Sharp edges, use protective gloves when
installing.
Tools Needed for Installation:

5/16” nut driver
Phillips head screwdriver - #2
High temperature sealant or furnace cement rated for continuous
use at 1,000oF minimum
Measuring tape
Parts Verication
See parts list on page 28 to verify components included in this vent
kit prior to installation.
NOTE: If installing onto wood, lap, or vinyl siding, the vinyl siding
kit should be used (sold separately, part number DV-822).
The vinyl siding vent kit, DV-822, is available from Empire Comfort
Systems, Inc. The depth is 3” (76 mm), which enables the vent cap
to be extended away from vinyl siding or projections. The wall depth
plus the additional 3” (76 mm) depth of the vinyl siding vent cap
extension should not exceed a total depth of 13 3/4” (349 mm).
If wall depth exceeds 13 3/4” (349 mm), extend system using
6 5/8” (168 mm) x 4” (102 mm) rigid venting (See Fireplace In-
structions for approved lengths) See Figure 38.
Installing Wall Thimble/Firestop Assembly
1. Fix replace to permanent location. If using rigid venting sys-
tem, install up to the location where it will exit the building.
2. Cut hole in wall for wall thimble/restop assembly into your
combustible wall. See Figure 37. Note: On brick or block
exterior wall a 7” (178 mm) diameter hole needs to be cut.
Measure the total wall thickness to determine whether or not
the extension thimble is to be used. If the combustible wall
depth is over 5 3/8” (137 mm), then the extension thimble
should be used. See Figure 37.
3. Install the wall thimble assembly through the framed
opening so the restop plate is on the interior wall. See
Figure 37. Telescope section should extend all the way through
the exterior wall. Attach with (4) 10 x 1” screws.
4. When placing the vent cap on an exterior wall covered with
combustibles such as wood, lap, or vinyl siding, install the
vinyl siding kit to the exterior wall sheathing.

Cutting Vent Tubes
This is the most important part of the installation. With the
replace (and the rigid venting system if used) xed to its permanent
location, the 6 5/8” (168 mm) diameter air inlet tube and the 4”
(102 mm) diameter ue outlet tube are to be marked and cut using
the following procedure.
5. Attach the inlet tube to the outside mounting plate. Align
tinnerman clips on the tabs of the air inlet tube to the holes on
outside mounting plate, and x with (2) #10 x 1/2” screws.
6. With the vinyl siding kit installed to wall (if necessary), insert
the 6 5/8” (168 mm) diameter tube with outside mounting plate
attached through hole in wall. Connect to collar on replace or
rigid vent system. Measure between wall or vent cap extension
and outside mounting plate (Figures 39 and 40).
