Cx complaint of improper flame in center burner. Came out today and removed unit and turned off gas and disconnected power. Removed lid and replaced gas valve and 2 lines going to orfice holder. Using a gas sniffer made sure no fuel was leaking anywhere. Tested with customer and found everything worked good. Then after center burner got hot the motion of simmer to medium the burner would pop and make a static noise. But if you kept turning the noise would go away. Called Techline and explained to them. They are stating that its caused by the propane and regulator at the tank. No on the unit. Sent two videos to Techline showing a normal sweeping motion and going slow when the noise is caused.That its working as intended and no further work needs to be done. Unit is working as intended. Job complete
