Restricting Vertical Vents - Napoleon Vittoria GD19N Installation And Operation Instructions Manual

VERTICAL VENTING INSTALLATION
Before attaching elbows to the collars on the back
of the fi replace, 1½" will need to be trimmed off
the 4" collar.
REAR VENT APPLICATION: Attach 4" and 7" elbows to
the fi replace. Secure with 3 screws and seal the joints and
screw heads using high temperature sealant. Proceed to
step 1 below.
TOP VENT APPLICATION:
1. Move the fi replace into position.
2. Fasten the roof support to the roof using the screws
provided. FIGURE 30. The roof support is optional. In this
case the venting is to be adequately supported using either
an alternate method suitable to the authority having jurisdic-
tion or the optional roof support.
3. Apply high temperature sealant to the outer edge of the
inner sleeve of the air terminal. Slip a 4" diameter coupler a
minimum of 2" over the sleeve and secure using 3 screws.
4. Apply high temperature
sealant to the outer edge of the
of the outside sleeve of the air
terminal. Slip a 7" diameter cou-
pler over the sleeve and secure
as before. Trim the 7" coupler
even with the 4" coupler end.
5. Thread the air terminal pipe
assembly down through the roof
support and attach, ensuring
that a minimum 16" of air termi-
nal will penetrate the roof when
fastened. If the attic space is
tight, we recommend threading
the Wolf Steel vent pipe collar
or equivalent loosely onto the
air terminal assembly as it is
passed through the attic. The
air terminal must be located
vertically and plumb.
6. Remove nails from the shin-
gles, above and to the sides of
the chimney. Place the fl ashing
over the air terminal and slide it
underneath the sides and upper
edge of the shingles. Ensure
that the air terminal is properly centered within the fl ashing,
giving a 3/4" margin all around. Fasten to the roof. Do NOT
nail through the lower portion of the fl ashing. Make weather-
tight by sealing with caulking. Where possible, cover the sides
and top edges of the fl ashing with roofi ng material.
7. Apply a heavy bead of waterproof caulking 2 inches
above the fl ashing. Slide the storm collar around the air
terminal and down to the caulking. Tighten to ensure that a
weather-tight seal between the air terminal and the collar is
achieved. Attach the other storm collar centered between the
air intake and air exhaust slots onto the air terminal. Tighten
securely. Attach the rain cap.
8. Continue adding rigid venting sections, sealing and
securing as above. Attach a 4" collapsed telescopic pipe to
the last section of rigid piping. Secure with screws and seal.
Repeat using a 7" telescopic pipe.

9. REAR VENT APPLICATION: Run a bead of high tem-
perature sealant around the outside of the 4" elbow. Pull the
adjustable pipe a minimum 2" onto the elbow. Secure with 3
screws. Repeat with the 7" telescopic pipe.
TOP VENT APPLICATION: Run a bead of high temperature
sealant around the outside of the 4" collar on the fi replace. Pull
the adjustable pipe a minimum of 2" onto the collar. Secure
with 3 screws. Repeat with the 7" telescopic pipe.
10. In the attic, slide the vent pipe collar down to cover up
the open end of the shield and tighten. This will prevent any
materials, such as insulation, from fi lling up the 1" air space
around the pipe.

RESTRICTING VERTICAL VENTS

Vertical termination installations exiting either from the
rear or the top fl ue collar of the fi replace may display a
very active flame. If this appearance is not desirable,
the vent exit must be restricted to reduce the veloc-
ity of the exhaust gases, thus slowing down the flame
pattern and creating a more traditional gentle appearance.
Remove the baffl e plate from the rear wall of the fi rebox,
exposing the fl ue gas outlet opening. Superimpose this outlet
hole with the smaller hole on the kit restrictor plate. Secure
with the two screws provided and replace the baffl e plate.

1. Remove the front and the door from the fi replace.
2. Remove the screws securing the baffl e plate. Figure 33.
Note: The baffl e rests on two screws that are attached to the
back of the fi rebox.
3. Using the screws supplied, attach the restrictor plate as
shown in Figure 34.
4. Replace the baffl e.
