Hello.
I bought a used Hayward h150fdn.
Brought it home and hooked up the gas line and waterlines and fired it up. Fired up perfect. However about 30 seconds later I noticed that the plastic cover was starting to melt on the side so I shut it off.
Opened the top and vacuumed the top of the exchanger clean. Still has same issue. What would cause this? It’s like the flames are TOO hot.
