Installed the automatic gas shut off switch in my Pentair Mastertemp 250 pool heater. The heater fired up after installation and is working fine.

This AGS was very easy to install. After seeing the fault indicator, I ordered this part, and in less than 2 minutes it was installed and my heater is operational again. (not including the time to remove the shroud around the heater)It would have cost me $250 to $300 at least to have a pro come out to diagnose and repair.What a deal.
