So I've got the forge set up. Go to start it up and my flame is super orange. It went from this when testing the burner. And after installing in the forge it's a bright yellow-orange. Only difference is its flame is enclosed inside the forge and it's mounted vertically instead of horizontal. It got nice and hot on this test fire. But not sure if it is efficiently enough. I believe the forge is inefficiently burning off alot of fuel. however nothing In the burner construction has changed between testing and installation.
