To install the PHOENIX DOMES Silicone Chimney Flashing Kit, follow these steps:
1. Positioning Your Stove:
- Start by positioning your stove in its desired location.
- If the vent pipe will be going straight up, it should go through one of the triangles in the 3rd layer.
- If you live in areas with high winds, you can secure the vent pipe to the struts with metal strapping later on.
- The pipe can also go out the side of the Dome, where the general principle remains the same. Stack enough vent pipe to figure out where it will penetrate through the Dome cover and start cutting an X, then a star shape until you are able to push a piece of pipe through it.
2. Trimming and Applying the Silicone Flashing:
- Trim down the rim of your silicone flashing with scissors so that it fits snugly over your chimney pipe.
- Stack any remaining pieces of stove/chimney pipe to determine the height at which one piece will protrude out through the various layers of your Dome.
- Slide the silicone flashing down and into place against the cover of your Dome, ensuring that one corner of the flashing points up and one points down.
3. Gluing the Vinyl Collar:
- Slide the vinyl collar down your chimney pipe, ensuring that the solid color half faces out and the drain section faces the ground.
- Apply the HH-66 vinyl cement to both surfaces intended to be joined and allow it to sit for 1 minute.
- Make sure not to apply any glue to the drain section at the bottom corner.
- Apply a thin coat of vinyl cement to both surfaces with a sacrificial paintbrush or the small brush included. Wait for about a minute and firmly press both sides together, ensuring there are no creases.
- Apply pressure to create a good bond, ideally with a partner on the inside of the Dome providing opposing pressure. Use a heat gun or hair dryer to warm the glue if it's cold out. The glue will be strong within minutes and at full strength after 24 hours.
4. Sealing and Finishing:
- Add any final lengths of chimney pipe as necessary and ensure all pieces are securely locked into place.
- Attach the storm cap on top.
- Use high-temperature RTV silicone and a caulking gun to run a solid bead along the junction between the silicone flashing and the chimney pipe to complete the waterproofing.
- If your vent pipe has a 90º 'through the wall' termination, follow the same principle for the silicone flashing and vinyl collar.
- Modify this process as necessary if you're installing a pipe flashing rather than a chimney flashing.
