Need help identify water heater manufacture to get parts

[cust]

Hello
I'm new here and appreciate any help
I have a very old water heater (more than 30 years old), currently it works great but only manually, ie there is no gas shut off since the diaphragm is punctured, i know it's dangerous so i take the at most precaution when i use it.
It been like this for over 6 years, and i have faced no problem.
Now i think it's time to fix it since i got experience in buying stuff online.
So I'm looking for spare parts to buy, but i can't identify the model!
I will post couple of pics for it, so anyone can identify it for me or tell me where i can get the spare parts:

Here are pics for the heater core:

And the main spare part i need:

The diaphragm is 53mm in diameter

I found an exact similar item on ebay but im not sure if it can fit since there is no dimensions specified:

The item is here:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180643638718
If i both of these will fit my heater then it can work as new

Hope someone can help

Do they have RGI's in Jordan? Put the case back on and call someone in who knows what they're doing. A punctured diaphragm will have no effect on whether the gas is shutting off. That's caused by seized internal parts. Generally speaking, parts are specific to appliance. You are operating a dangerous gas appliance and getting advice here should not happen, other than to leave it to an expert.

The gas shutoff when the water pressure inside the diaphragm gets lower than the spring power pushing the diaphragm so the other rubber that shutoff the gas close.
what i did is removing the rubber that closes the gas so it's always open disregard water pressure.
btw, there are RGI's in Jordan and believe me they won't do any other work than the one im capable of doing by my self, and besides there are no available parts for this model anywhere

So what happens if your water goes off while you've got the gas on - are you trying to blow you and your house up?

Time for a new heater or a kettle to boil some water.

Simply boiling water inside the heat exchanger then the pressure will break the valves, until this moment someone will notice the gas still running then will close the source.
Nothing will blow up; At any moment there won't be enough gas inside the heater to blow up.
BTW, it seems this water heater is from Saunier Duval Opalis family!

That'll teach me to get sidetracked while replying.

LOL @ How the control assembly is held together with twisted wires instead of screws.
FWIW I think it might be an old Vaillant water heater and I think you will be lucky if that diaphragm on ebay fits.
Why dont you save a fiver and your life by investing in a new water heater and getting someone who knows what they're doing to install it?
