Ferguson Strap-On Aquastat & Installation Diagram

If you're wondering how to make your inside hot air furnace work with your outdoor wood furnace, well here you go! This kit will prevent you from having two thermostats on the wall. Doing the installation with this kit also makes it seamless between the two furnaces. For example, if you run out of wood outside, your indoor furnace will function normally until the outside wood furnace catches up with the heat.
