Sent the wrong parts for my big buddy heater
LP regulator was wrong but I was able to make it work. Both sets of gaskets were wrong so I cut them and glued them together to make them work. I will be firing it up outside in case it blows up.

Tile gasket was damaged allowing too much oxygen to get to the gas and resulting in a huge flame in that particular tile then it would pop and it would go out completely

To start remove the outer grill then you can remove the heat shield to expose the upper and lower of the tiles then you must remove the upper and the lower bar that runs across the top and bottom of the tiles be extremely careful and when pulling the tiles out as they are more fragile than eggs .
The tile gasket is right behind the tile setting in a little pocket
