DVVK-4RE VENT KIT INSTALLATION INSTRUCTIONS

CAUTION: Sharp edges, use protective gloves when installing.

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” (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 Instructions for approved lengths) See Figure 2.

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 1) into your combustible wall. 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 (Figure 1).

3.Install the wall thimble assembly through the framed opening so the firestop plate is on the interior wall (Figure 1). 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 com- bustibles 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 3A and 3B).
