Original Apache heater controls are between the pilot seats. There is a fuel shut off (reostat type clockwise to close, couter clockwise to open) that must be opened before operating heater. Otherwise when you turn it on all you are doing is blowing more cold air in on you! Other than that it works just like most others, Hi, Low, and a vent mix control push pull knob. It works well but takes time to heat up, and if you do not have the mix air right you over heat the heater and pop the breaker, OR you pump too outside air into the mix and never get it warm.PILOTO said:hello! 1.-does anybody knows how the heater works on the apache? 2.-is there a pitot or static heat? if the answer is yes where are those located? thank you all.
