1. The Water heater Safety will NOT allow gas to flow thru the gas valve if no flame is present. The gas Valve opens for about 7 seconds on an ignition sequence. IF the Piezo fails or the flame does NOT light the gas valve shuts down. It will do this for 3 tries about 30 seconds apart.
2. BUT, those 3 tries will cause 21 seconds of LP to flow and THAT will cause a odor in and around the water heater. Long after the sequence stopped.
3. LEAVE the LP tank valve OFF. Start a LP ignition sequence and observe the water heater. See if the Piezo sparks and sparks a GOOD spark with a good gap between the probes. A common mistake novices make when installing a water heater(if you installed it) is to pull the Ignition spark plug cable away from the electrode Spade terminal inside the orange/black rubber boot. Pull back the boot and see if the wire is connected and secure on the electrode. IF no spark and the connections are good, go to the Ignition module and verify the Electrode spark nwire is indeed still connected to the control module. If so, then the Piezo tower on the board is bad. Doug
PS, I will bet your input gas line connection may not be tight and is also leaking,
Hi Doug,
Thanks for the info.
I did install it myself. It was simple and straightforward.
I will check the spade terminal and see if I accidentally pulled on it somehow and disconnected it.
