DVVK-4RE VENT KIT INSTALLATION INSTRUCTIONS
CAUTION: Sharp edges, use protective gloves when
installing.
Tools Needed for Installation:
Sheet metal snips
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 Verification
See parts list on page 32 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 47.
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 (Figure 46)
into your combustible wall. 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 (Figure 46).
3. Install the wall thimble assembly through the framed opening so
the firestop plate is on the interior wall (Figure 46). 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 48 and 49).
