If the noise is not coming from the fan as Buffalo suggests, it is most likely the expansion and contraction of the heat exchanger. The old school way to lessen the noise of expansion is to bank the combustion chamber with a hammer. I don't recommend it today because the metal is so thin (thus all the noise) and you may damage it. You will get used to it and the noise may soften the more it is used. You will never get it to stop.

check for dirt in the air gap that is formed between the electromagnet and the contact form. if there are any shading coils on the magnet check for a broken one.

The thermocouple is likely defective...(Copper wire heated by the pilot) or the pilot itself is too small or dirty....the pilot must be BLUE , not yellow like a candle...and it must envelop the top portion of the thermocouple....you could also have an auxiliary limit or ECO wired in series with the thermocouple circuit that could be open.....also make sure the thermocouple is inserted all the way and is in the pilot flame as mentioned above

Testimonial: "Thank you for the feed back, do I have to remove the entire side panel in order to replace the thermocoupler?"
Sounds like a bad fan switch. The switch is located on the heat exchanger and is 110 volt bi-metal switch. Follow the wires from the blower going back to the heatexchanger. Graingers can get you a new switch if you give them your model number. www.grainger.com.

I have the same heater with the same problem. I took the top cover off, removed the ignitor and bent the probes slightly closer. Use two needle nose to prevent breakage of the holder. It has been working fine since.
