There are different types of chimney cap wind devices. Pay attention to the model and type so as to fix and secure it properly on your chimney. They are useful in keeping pests, debris, and dirt from entering the chimney.
Step 1 - Tighten Screws
For a single-flue chimney cap, position the device in place and use a screwdriver to fasten and secure it. Wind and harsh rains can easily loosen screws on the cap. Inspect the cap regularly and tighten the screws in case they are loose. Always use high quality screws and replace damaged or worn out pieces.
Step 2 - Fasten Chimney Caps on Tile Flue
It is advisable to use both screws or nuts and chimney cap sealant. This holds the device in place more strongly. Silicone sealer can be used for inside mount chimney caps with tile flues.
Step 3 - Fasten Chimney Caps on Metal Flue
Make sure to use chimney cap sealant that is resistant to heat, as metal flues heat up and can easily melt adhesive. Use a caulking gun to apply a thick bead of sealant around the chimney cap. For a strong fit, press down on the device and use a putty knife to smooth the sealant and prevent it oozing from the sides.
