Flushing for snow country specifications for chimneys with an outer diameter of 200 mm for installing double chimneys without a roof.
It becomes a stainless steel 304 product with black heat-resistant paint.
The top plate is made to be exactly horizontal with a slope of 30° and a slope of 5.8 inches.
The corresponding roof slope is 26° to 36°, which is about 4.9 to 7.2 sun slopes in Japanese roof slopes.
If the top edge is not horizontal due to the wide range of slopes, you can use corrugated iron scissors to cut the top edge horizontally according to the slope you are using.
Made of 304 stainless steel with heat-resistant black coating.
The dimensions of the base are 720 mm wide x 810 mm long.
The upper part of the opening is 210 mm in diameter and the lower part of the opening is about 350 mm in diameter.
The rise is 445 mm from the center.
In many cases, it is better to install the roof support bracket upside down, or to attach it from behind the ceiling.
It may not be possible to cover the flashing because the flashing and the roof support bracket interfere.
Place the storm collar on top of the flashing and caulk around the storm collar to prevent rainwater from entering.
Flushing and chimney caulking are not absolutely necessary.
Caulking materials are sold at home centers. There is no problem with using silicone sealant sold for about 500 yen.
Even ordinary silicon has a heat resistance of about 150°C.
In general, the temperature outside the insulated double chimney is about 70 degrees at a distance of 1 m from the wood stove, but it drops to about 40 degrees when it reaches the roof surface.
