*IMPORTANT* Minimum clearance between vent pipes
and combustible materials is one (1") inch (25 mm) on
bottom, sides and top.

Elbow 7TDVRT90 must be used in
Vertical Sidewall installations.
pipe must be centred inside the 7" pipe
coming off the 7TDVRT90 transition
elbow.
STEP 1
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. Fig. 48 or 50.
(For combustible walls first frame in opening. Fig. 49).

(Fig. 52) 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

and outer elbow. Again secure joints with three (3) sheet
metal screws. Wipe off any excess high temperature
sealant.

ARE CONCENTRIC
STEP 4
(Fig. 53) Measure the horizontal length requirement plus
1-1/2" overlap, i.e. from the elbow to the outside wall finish
plus 1-1/2" (or the distance required if installing a second
