1_Left lever down ( the one opening both control boxes ). I feel heat; One inch over the windshied dashboard ports.
2_ + Middle lever down ( to run the heater fan ). I feel heat; Four inches over the ports.
This is at idle.
Running, I would say, it becomes, 2 inches and 6 inches.
With my hand feeling good warm air.
I forgot to see what happens with the front door sliders.
My bus has lost it's front control box ( it used to be controled by the middle lever ). Box and cable removed, direct duct on the side of the big pipe ( iso, box ) ( was done long ago )
This goes just behind the front seats, right ? I have good heat from there too.
I have not insulated the big pipe, neither checked for all leaks. I guess there is much to gain, going through this. My main concern was to have the control boxes and cables perfectly right. ( I just found, that it has been wrong for 20 years thanks to a bad NEW heat control box ).
