Using Flexible Vent Components - Napoleon GD33NR Installation And Operating Instructions Manual

USING FLEXIBLE VENT COMPONENTS

Use only approved aluminum flexible liner kits marked:
"Wolf Steel Approved Venting" as
identified by the stamp only on the 7"
outer liner.
HORIZONTAL AIR TERMINAL INSTALLATION
For safe and proper operation of the fireplace, follow
the venting instructions exactly.
1. Cut or frame a hole in an exterior wall with a minimum
round or square opening listed in TABLE 2 on page 6.
Secure the firestop spacer over the opening to the interior
wall.
2. Stretch the 4" diameter aluminum flexible liner to the
required length taking into account the additional length
needed for the finished wall surface. Slip the liner a mini-
mum of 2" over the inner sleeve of the air terminal and
secure with 3 #8 screws. Apply a heavy bead of the high
temperature sealant.
3. Using the 7" diameter flexible aluminum liner, slide
over the outer combustion air sleeve of the air terminal and
secure with 3 #8 screws. Seal as before.

The air terminal mounting plate may be recessed into
the exterior wall or siding by 1½", the depth of the return
flange.
GD33 and BGD33: When venting straight out the back, only
the rigid vent can be used. Do not use flexible vent. For all
other venting configurations, flexible vent is acceptable.
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot
when using Simpson Dura-Vent, Selkirk Direct Temp,
American Metal Amerivent, or Wolf Steel rigid vent com-
ponents and a minimum 1 inch rise per foot when using
Wolf Steel flexible vent components.
For safe and proper operation of the fireplace, follow the
venting instructions exactly.
4. Insert the liners through the firestop maintaining the
required clearance to combustibles. Holding the air termi-
nal (lettering in an upright, readable position), secure to
the exterior wall and make weather tight by sealing with
caulking (not supplied).
5. Apply a heavy bead of the high temperature sealant,
supplied with the unit, to the inside of the 4" liner approxi-
mately 1" from the end. Slip the liner a minimum of 2" over
the fireplace vent collar and secure with 3 #8 screws.
6. Using the 7" diameter flexible aluminium liner, apply
sealant, slide a minimum of 2" over the fireplace combus-
tion air collar and secure with 3 #8 screws.

2. Stretch the inner aluminum
flex liner to the required length.
Slip the liner a minimum of
2" over the inner sleeve of the
air terminal connector and
secure with 3 #8 screws.
Seal using a heavy bead of
the
sealant. (Fig. 29)

3. Repeat using the outer
aluminum flex liner. (Fig. 29)
4. Thread the air terminal
connector / liner assembly
down through the roof. The air
terminal must be located
vertically and plumb. Attach
the air terminal connector to the roof support, ensuring that
the top of the air terminal is 16" above the highest point that
it penetrates the roof. (Fig. 30)
