There is a very real chance of unscrewing the valve packing and introducing a fuel leak into the nose compartment (it's a rod that engages a valve on the other side of the firewall) by operating this valve every time you run the heater. I know what the book says, but I suggest that that knob be painted red and it only be used as a fire valve in case of a heater emergency. There are two electrical fuel solenoid valves on the unit itself so if they are operating properly (as required to be checked by AD) this valve is an unnecessary complication and potential bad day.
