The obvious thing that could cause this is a leak in the burner assembly/connection. You wrote that there are no leaks. Normally, you would check for leaks in joints before turning on a gas appliance. However, in this case there is a BASO valve involved which restricts gas from the joint until the burner is lit. Did you test for leaks before you lit the main burner? If so than you did not test the joint, because no gas is present yet. The burner must be on to test the line. If this is the case then gas will continue to leak all the time the burner is on. And cause a very dangerous situation, because it is likely that the reason you think it is a single puff is because the mercaptan (odorant that is added to otherwise odorless NG gas) could drop from the joint down past the intake vents and be sucked into the combustion chamber reducing the "smell" in the room. However, gas rises because it is lighter than air and the room could be filling with now less odorous gas. This is a long explanation of a simple solution. . . which is check the joint to the main burner/BASO valve when the burner is ON. If there is no leak there than you should shut the thing down and call a plumber "Tout de suite". Otherwise use Rector Seal and reseat the joint.

Beware when working with electrical equipment. It may cause electric shock. Check the power supply wires, connections with heating coils. If they are ok then possibly heating coils require replacement.

I would try their website; www.statewaterheaters.com They should show a list of their service agents.

The three most common reasons for this happening to you are 1) a defective gas valve, 2) a rusty thermopile, and/or 3) the automatic shut-off not working as it should. So, the most common reason for many people having this problem stems from having a gas valve that is not working as it should. When your gas control valve is faulty, it will mean that your burner is not going to be igniting as it should-or at all. Something that worked for me one time was to turn the Temp all the way down then all the way to Max a couple of times..gradually. Why it worked I don't know. Got a couple more years out of it though. Good luck! Best to you.

there is pressure adjustment, just temp. water pressure in + water pressure out
