Radiant tube heater help

I have a radiant tube heater that's been installed for 2 years. And has worked perfect. Now It only heats up at the very beginning of the tube and the rest of the tube has 0 heat . Any thoughts or anybody else run into anything like this?

    Check the manifold pressure. Check for obstructions in the tube, vent, and orifice. Dont operate it until you figure it out because several of the possibilities could result in abnormal amounts of carbon monoxide or overheating things and starting a fire.
