Parts Verification
See parts list on page 29 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 Instruc-
tions for approved lengths)
See Figure 41.
Installing Wall Thimble/Firestop Assembly
1. Fix fireplace to permanent location. If using rigid venting system,
install up to the location where it will exit the building.
2. Cut hole in wall for wall thimble/firestop assembly into your
combustible wall.
See Figure 40.
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 40
.
3. Install the wall thimble assembly through the framed
opening so the firestop plate is on the interior wall.
See
Figure 40.
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
fireplace (and the rigid venting system if used) fixed to its permanent
location, the 6 5/8” (168 mm) diameter air inlet tube and the 4” (102
mm) diameter flue 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 fix 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 fireplace or
rigid vent system. Measure between wall or vent cap extension
and outside mounting plate (
Figures 42 and 43
).
