Fireplace Vent Connection; Using Rigid Vent Components - Napoleon Vittoria GD19N Installation And Operation Instructions Manual

5. Remove nails
from the shingles,
above and to
the sides of the
chimney. Place the
fl ashing over the air
terminal connector
leaving a min. 3/4"
of the air terminal
connector showing
above the top of the
fl ashing. Slide the
fl ashing underneath
the sides and upper
edge of the shingles.
Ensure that the air
terminal connector
is properly centred
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.
6. Aligning the seams of the terminal and air terminal
connector, place the terminal over the air terminal connector
making sure the liner goes into the hole in the terminal.
Secure with the three screws provided.

USING RIGID VENT COMPONENTS

The vent system must be supported approximately every
3 feet for both vertical and horizontal runs. Use Wolf Steel
vent spacers W615-0033 every 3 feet and either side of each
elbow to maintain the minimum 1¼" clearance between the
outer and inner vent pipes. Use Wolf Steel support ring as-
sembly W010-0370 or equivalent noncombustible strapping
to maintain the minimum clearance to combustibles for both
vertical and horizontal runs.
All inner exhaust and outer intake vent pipe joints may
be sealed using either Red RTV high temp silicone seal-
ant or Black high temp Mill Pac with the exception of the
fi replace exhaust fl ue collar which must be sealed using
Mill Pac (not supplied).

1. Move the
fi replace into posi-
tion. Measure the vent
length required between ter-
minal and fi replace taking into account the
additional length needed for the fi nished wall surface
and any 1¼" overlaps between venting components.
2. Apply high temperature sealant to the outer edge of the 4"
inner collar of the fi replace. Attach the fi rst 4" vent component
and secure using 3 self tapping screws. Repeat using the 7"
vent component.

7. Apply a heavy bead of weatherproof caulking 2" above
the fl ashing. Note: Maintain a minimum 2" space between
the air inlet base and the storm collar. Install the storm
collar around the air terminal and slide down to the caulking.
Tighten to ensure that a weather-tight seal between the air
terminal and the collar is achieved.

FIREPLACE VENT CONNECTION

1. Install the 4" diameter aluminium fl exible liner to the
fi replace. Secure with 3 screws and fl at washers. Seal the
joint and screw holes using high temperature sealant W573-
0007 (not supplied).
2. Install the 7" diameter aluminium fl exible liner to the
fi replace. Attach and seal the joints with high temperature
sealant W573-0002 (not supplied).

NOTE: Before attaching elbows to the collars on the
back of the fi replace, 1½" will need to be trimmed off
the 4" collar.
3. Holding the air terminal (lettering in an upright, readable
position), insert into both vent pipes with a twisting motion to
ensure that both the terminal sleeves engage into the vent
pipes and sealant. Secure the terminal to the exterior wall and
make weather tight by sealing with caulking (not supplied).
The air terminal mounting plate may be recessed into
the exterior wall or siding by 1½", the depth of the return
fl ange.
EXTENDED HORIZONTAL AND CORNER
AIR TERMINAL INSTALLATION
1. Follow the instructions for "Horizontal Air Terminal Instal-
lations", items 1 to 3.
2. Continue adding components alternating inner and outer
venting. Ensure that all 4" venting and elbows have suffi cient
vent spacers attached and each component is securely fas-
tened to the one prior. Attach the 4" telescopic sleeve to the
vent run.
Repeat using a 7" tel-
escopic sleeve. Secure
and seal as before. To
facilitate completion, at-
tach 4" and 7" couplers
to the air terminal.
3. Install the air terminal. See item 3 of
the Horizontal Air Terminal Installation.
Extend the 4" telescopic sleeve; connect
to the air terminal assembly. Fasten with
self tapping screws and seal. Repeat using
the 7" telescopic sleeve.
