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
The vinyl siding vent kit,
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).
