Vapor x High Limit
The LP gas vapor temperature sensor located in the gas pipe train downstream from the vaporizer, has opened indicating that the vaporizor is running too hot and must be readjusted. This sensor is set at 200°F (93°C) and automatically resets itself when cool. The message will distinguish between which burner caused the shutdown. The reference to the number one (1) is telling you that it is burner number 1 which is the bottom most fan/heater unit, is where the malfunction is located.
Try adjusting the vaporizer coils farther away from the burners flame. You may also want to try switching the burner mode from Hi/Lo to On/Off, especially on warmer days.
