Parts Verification
See parts list on page 20 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” (76mm), which enables the vent cap to
be extended away from vinyl siding or projections. The wall depth
plus the additional 3” (76mm) depth of the vinyl siding vent cap
extension should not exceed a total depth of 13 3/4” (349mm).
If wall depth exceeds 13 3/4” (349mm), extend system using
6 5/8” (168mm) x 4” (102mm) rigid venting (See Fireplace Instruc-
tions for approved lengths)
See Figure 28.
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 27.
Note: On brick or block
exterior wall a 7” (178mm) 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” (137mm), then the extension thimble should be
used.
See Figure 27
.
3. Install the wall thimble assembly through the framed open-
ing so the firestop plate is on the interior wall.
See Figure 27.
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 perma-
nent location, the 6 5/8” (168mm) diameter air inlet tube and the 4”
(102mm) 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” (168mm) 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 29 and 30
).
