Plan your installation by drawing a sketch of the area that you will be working on. Make sure to include the size and shape of the vent, as well as the location of any electrical wiring or other obstructions.
Placement is critical, and must be done correctly to ensure efficient air combustion. Vent placement should be sloped so that the air is directed downwards and away from surrounding surfaces.
To ensure correct placement, use a sketch to follow the contours of the area. Remember that you want the vent to be sloped and positioned so that air is directed downwards and away from other surfaces.
Ensure Air combustion
Ensure air combustion by setting up an apparatus that will generate heat and smoke. This can be done using a stove, fireplace, or open flame.
Make a Slope
Make a slope by cutting a piece of wood that is the same size as the vent and attaching it to the side of the vent. This will help direct air downwards and towards the vent
Termination of Area
When installing an area vent, make sure to terminate it by cutting the wire or tubing. This will prevent debris from entering the vent and blocking its operation.
Lastly, you’ll need to make sure that the area around the vent is enclosed so that airborne debris doesn’t get in the way.

Frame a 4 sided hole in the floor with a dimension of 2 inches larger than the vent’s outer diameter. Place the support assembly on the upper side of the hole and support band on top. Spacers ensure complete clearance of combustibles.
Nail the support assembly to the floor with 3 three-inch nails on each side.
Lower the first vent section through the support band and clamp the band to hold the vent at the desired height. Also, secure the band to the vent’s casing with four 8*3/8 inch long sheet metal screws.

The support assembly will support up to 60 inches of the vent. If the vent exceeds this height, then use additional support assemblies.

Where your vent passes through a floor or roof, there a firestop is required. Place the spacer around the vent with the spacer brackets towards the framed hole.
Push the firestop flat and fasten it by four nails to the framing. You should seal the vapor barrier to the firestop or the ceiling using an appropriate caulking compound.

Attic Insulation Shield
It is needed where the vent passes into an attic space.
Where there is the height for this shield, it is permissible to construct an enclosure with a 1-inch air space clearance to the outer pipe.
The opening must be framed at 1 inch of clearance to the outside casin of pipe with framing material of the same dimension as the ceiling.
Assemble the support and bolt it to the wall with 4-inch anchors adjustable to the wall material.
Lower the length of the vent through the support and twist it to lock to the tee. Do tighten the support’s clamp band and further secure the vent with four 8*3/8 sheet metal screws into the vent case.
Continue with additional vent lengths as necessary. Install wall bands at least at every 6 inches of vent rise.
While the vent protrudes through, slide the flashing down until its base sits on the roof.
Place the upper side of the base under the shingles and the lower side over the shingles.
Slide a storm collar down to the flashing top and seal with silicone
off the top of the vent with a rain cap.
Cut a hole in your wall where you intend to pass the vent. Frame the square hole dimensions 2 inches larger than the outside diameter of your vent.
Now install firestop spacers inside and outside both of the openings. Fasten them with 1-inch nails at each corner. It should be a minimum of 1 inch.
Now, through the firestop spacers, place a length of the vent.
From the outside of the building, connect a 90-degree elbow or a tee to the horizontal vent.
The vent must be enclosed by a chase at least to the roofline. Also, the enclosure must consist of a 28 gauge sheet metal box spacing 2 inches from the vent.
The chase must be caulked to prevent moisture entrance.
