I have a goodman Model #GUN100-4 furnace, Serial #911129465 I have a few questions about this unit. why will the furnace cycle just fine for hours and hours then all of the sudden stop. The only way I can get it to start back up, is to either shut the power switch off and on a few tmes very quickly, or by cycling the auto/fan switch on the thermostat back and forth quickly a few times. before either of these procedures is done the furnace will not try to ignite, the blower does not cycle, etc. I can however also remove the vaccum line that is attached to the exhaust blower unit apply a small amount of vaccum until the vaccum switch closes. If I do this and count to 10 , release the vaccum, reattach the line to the blower housing stand back and count to 15, the furnace will ignite and run fine for hours. Is it possible that I have a faulty ignition module?, and by doing this wierd procedure I am somehow resetting it? Also when I pulled te side panal off to try and figure this problem out, I did find alot of small pieces of rust inside, I cleaned these up with a small shop vac, but still dont know where they are from. any help would be greatly appreciated

I have a gas line in the garage and a small gas heater. I need to find out if I can use a 3/8 dia. rubber gas hose about 6ft. in length so that I can move the heater within the garage. Also where can I get this hose perferably with a 3/8 male plug on one end and a 1/2 male plug on the other. Thanks for your help!
