We are glad to hear the heater is performing as expected, Bill. It’s unfortunate that shipping damage forced you to install it as‑is, but it’s good that the dents don’t seem to affect function. The occasional high‑pitched vibration from the gas valve can be annoying, though it’s reassuring that it isn’t causing performance issues. Hopefully it continues to run reliably despite those setbacks.
