DVVK-4RE VENT KIT INSTALLATION INSTRUCTIONS
CAUTION
Sharp edges. To avoid injuries, wear safety gloves when
handling the vent components.
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 600ºF minimum
•
Measuring tape
Parts Verification
See parts list on page 38 to verify components included in this
vent kit prior to installation.
NOTE:
Use Vinyl Siding Vent Kit DV-822 if installing the vent kit
onto wood, lap, or vinyl siding. DV-822 is available from Empire
Comfort Systems, Inc. The depth is 3 inches, which enables the
vent cap to be extended away from vinyl siding or projections.
The wall depth plus the additional 3 inches depth of the vinyl
siding vent cap extension should not exceed a total depth of
13-3/4 inches.
If wall depth exceeds 13-3/4 inches, extend system using
6-5/8 x 4-inch rigid venting (See Fireplace Instructions for
approved lengths).
See Figure 63.
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 62
)
into your combustible wall. Note: On brick or block exterior
wall a 7-inch 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 inches, then the extension thimble should
be used (
Figure 62
).
3. Install the wall thimble assembly through the framed opening
so the firestop plate is on the interior wall (
Figure 62
).
Telescope section should extend all the way through the
exterior wall. Attach with four 10 x 1 inch 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 inch diameter air inlet tube and
the 4-inch 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 two #10 x 1/2 inch
screws.
6. With the vinyl siding kit installed to wall (if necessary), insert
the 6-5/8 inch 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 64 and 65
).
