Reznor won't light

[Skyking1992]

I have an older Reznor unit heater. I used it a couple years ago and it worked fine. Didn't heat my shop last year. This year I could not get the pilot light to work. I disconnected the black pipe at the furnace (with good ventilation) and I have gas flow. I assume the thermocouple is not the problem - the pilot should still light with the button held in. Any ideas? I guess my next step is to remove the pilot assembly to see if there are any obstructions. Should I be able to feel or smell gas flow from the pilot when the control knob is depressed?

Thanks,

When button is pressed youll hear gas ad sometimes smell it. I have found alot of them plugged after sitting. Try to remove and clean and see what happens. sometimes you have to rebleed a gas line thats been sitting also.

if you dont hear or smell gas remove the pilot tube and blow thru it.

Thanks guys,

Got it working. Not sure of the problem. I disassembled the pilot. Tube was clear but I'm not sure of the orifice - that's an awfully small hole. I found a small wire to put through it. I once again bled the main line by disconnecting the main line at the union, reassembled everything and it lit. When I got this furnace it had a power vent option on it, but the motor was frozen. I wasn't sure if I was going to vent it horizontally or vertically. I found a new surplus motor on ebay and everything seems to work fine. Now I just need to finish my vent pipe. Again thanks,
