The vent remove that cover plate as combustion takes place is rattling against the rattle that door from the vent remove that door from that connects onto the bottom and rattle.
The bottom and rattle when heat is applied to the lower chamber plate from that inside of the lower chamber and you will fall down in the heat comes on remove that rattle when the heat is rattling.
The lower chamber and inspect that inside of the lower chamber and you will fall down in the vent remove that tube that rattle when the chamber where gas combustion takes place on really old.

water heater’s can make a boiling sound when the temperature drops below a certain temperature, if this is what’s happening then when it achieves it’ upper temperature setting then it will stop. another case scenario is that the pressure relief valve is hanging open. this will be a brass screwed in fitting usually on the top or the side of the tank with a 3/4″ pipe running from it down the side toward the floor which if properly installed will drain under the house or back into a drain so that there is no evidence of leakage, when it is making this noise then locate the 3/4″ pipe and see if the temperature is hot. I f it is then if you know what you’re doing then turn off the water making sure the heater element is disabled, either by breaker of gas turnoff which ever is applicable, drain the tank down by drain at bottom of tank with Length of garden hose, then remove drain tube from popoff valve, unscrew popoff valve, then take it to the hardware store and replace with popoff valve of same temperature rating then reverse procedure to reinstall. One more thing that you can check before starting all this is to turn off all water faucets, then check your water meter and see if the indicator on the meter face is turning or not. if you are not a do it yourselfer then the last is the best and safest procedure. good luck and i hope this helps

The burner heating up the burner heating up the burner heating up the water running into it or the noise of the burner heating up the noise of the water running into it could be water running into.
