Locate vent opening on the wall. It may be necessary to first
position the fireplace and measure to obtain hole location.
Depending on whether the wall is combustible or non-
combustible, cut opening to size.
(For combustible walls first frame in opening).

STEP 2
Fig. 20. Measure wall thickness and cut adjustable zero
clearance sleeve parts to proper length (MAXIMUM 12"/
305mm). Adjust sleeve to minimum (9-3/8" x 9-3/8") and
attach to firestop with #8 sheet metal screws (supplied).
Install firestop assembly.
STEP 2
Zero clearance sleeve is only required for
combustible walls.

STEP 4
(Fig. 22) Measure the horizontal length requirement
including a 2" (50mm)overlap, i.e. from the elbow to the
outside wall finish plus 2" (or the distance required if
installing a second 90º elbow).
STEP 3
(Fig. 21) Apply a bead of high temperature sealant to the
inner and outer flue collars of the fireplace and using
appropriate venting component(s) attach to fireplace with
three (3) screws. Follow with the installation of the inner
and outer elbow. Again secure joints with three (3) sheet
metal screws. Wipe off any excess high temperature
sealant.
