This switch monitors the pressure differential across the air metering orifice to verify adequate combustion airflow before ignition can proceed. Once the blower generates sufficient air movement, the AFS closes its contacts, completing the circuit to the hot surface igniter (HSI) and initiating the fuel

Love these socks!
The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

Durable non see through fabric
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
This room divider is exactly what I need. It is very durable and easy to move around. You can’t see through the fabric. I love it. My reason for purchasing this divider is to use as a divider and as a backdrop holder. And it serves both purposes perfectly. It looks much better in person than on camera. It did have the spots on one side on all of them but in a few days they went away. It foldaway and tucked away easily.

Great product
Color: Black, Size: 4 Panel-88''
Love the look of this after it’s put together. It’s pretty sturdy and the connecting clips allow you to shape it different if you need it to fit in a corner. We use this at work so it’s great for the space we use it in. A little hard to store because it doesn’t fold up nicely because of the feet on it but I’m happy with it overall.
