Vertical Installation; Appliance Vent Connection - Napoleon Arlington GDS20NNSB Installation And Operation Manual

3.2

vertical installation

This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor.
See the "accessories" section to order specifi c kits required.
A. Determine the air terminal location, cut and frame a square opening,
as illustrated, in the ceiling and the roof to provide the minimum 1"
(25mm) clearance between the vent pipe and any combustible material.
Try to center the vent pipe location midway between two joists to
prevent having to cut them. Use a plumb bob to line up the center of
the openings. A vent pipe shield will prevent any materials such as
insulation, from fi lling up the 1" (25mm) air space around the pipe. Nail
headers between the joist for extra support.
B. Apply a bead of caulking (not supplied) to the framework or to the
Wolf Steel vent pipe shield plate or equivalent (in the case of a fi nished
ceiling), and secure over the opening in the ceiling. A fi restop must be
placed on the bottom of each framed opening in a roof or ceiling that
the venting system passes through. Apply a bead of caulking all around
and place a fi restop spacer over the vent shield to restrict cold air from
being drawn into the room or around the fi replace. Ensure that both
spacer and shield maintain the required clearance to combustibles.
Once the vent pipe is installed in its fi nal position, apply red RTV
silicone (W573-0002) (not supplied) between the pipe and the fi restop
assembly.
C. 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.

appliance vent connection

A. Attach the adjustable pipe to the last section of rigid pipe. Secure with
screws and seal.
B. Install the inner fl ex pipe to the appliance. Secure with a minimum of
three screws and fl at washers when installing 3"/5", 4"/7" or 5"/8"
venting, or six screws and fl at washers when installing 8"/10" or
8"/11" venting. Seal the joint and screw holes using Mill Pac sealant
(W573-0007) (not supplied).
C. Run a bead of high temperature red RTV silicone sealant (W573-
0002) (not supplied) around the inside of the air intake collar. Pull the
adjustable pipe a minimum 2" (50.8mm) into the air intake collar.
note:
Always fi nish vent system installation with the appliance vent connection. Ensure that the sealant is not visible on the
exterior pipes once installation is completed. An optional decorative black band may be available with this appliance.
In the event that the venting must be disassembled, care must be taken to reseal the venting.
