Vertical Air Termination Installation Using Rigid Venting - Napoleon Vittoria GD19N-2 Manuel D'installation Et D'opération

4.3.6 vertical air termination installation using rigid venting

WARNING
!
• Maintain a minimum 2" (51mm) space between the air inlet base and the storm collar.
note:
Fastening hardware provided with appropriate roof terminal and liner kits.
Before attaching elbows to the collars on the back of the appliance, 1 1/2" (38.1mm) will need to be trimmed off
the 4" (101.6mm) collar.
REAR VENT APPLICATIONS ONLY: Attach 4" (101.6mm) and 7" (177.8mm) elbows to the appliance. Secure
with 3 screws and seal the joints and screw heads using high temperature sealant. Proceed to step A below.
TOP AND REAR VENT APPLICATIONS:
Move the appliance into position.
A.
B. Fasten the roof support to the roof using the screws provided. 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 jurisdiction or the optional roof support.
C. Apply high temperature sealant W573-0007 (not supplied) to the outer
edge of the inner sleeve of the air terminal. Slip the inner coupler a
minimum of 2" (51mm) over the sleeve and secure using 3 screws.
D. Apply high temperature sealant W573-0002 (not supplied) to the outer
edge of the of the outside sleeve of the air terminal connector. Slip
the outer coupler over the sleeve and secure as before. Trim the outer
coupler even with the inner coupler end.
Thread the air terminal connector / vent pipe assembly down through
E.
the roof support and attach, ensuring that a minimum 16" (40.6cm)of
air terminal connector 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 connector / vent pipe assembly
as it is passed through the attic. The air terminal connector must be
positioned vertically and plumb.
F. Remove nails from the shingles, above and to the sides of the air terminal
connector. Place the fl ashing over the air terminal connector and slide it
underneath the sides and upper edge of the shingles. Ensure that the air
terminal connector is properly centered within the fl ashing, giving a 3/4"
(19.1mm) 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.
G. Apply a heavy bead of waterproof caulking 2" (51mm) above the fl ashing. 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 connector and the collar is achieved.
H. Continue adding rigid venting sections, sealing and securing as above. Attach the inner collapsed
telescopic sleeve to the last section of rigid piping. Secure with screws and seal. Repeat using the outer
telescopic sleeve.
Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the inner elbow
I.
for rear vent applications or the inner collar for top vent applications. Pull the telescopic sleeve a
minimum of 2" (51mm) onto the elbow. Secure with three screws. Repeat with the outer telescopic sleeve.
TOP VENT APPLICATIONS ONLY:
K. 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" (25mm) air space around the pipe.
