Suburban SW6P Water Heater Intermittent Flame Out on Start

Thanks so much, will go through it again this weekend.

I also went through all the grounds and connections last year. Huge improvement. Lights don't dim as more get powered on.

Where can I find instructions on removing the main orifice?

Found this http://dutchmen.com/image/data/documents/parts/Suburban_Water_Heater_Service_Manual.pdf One comment in the doc talks about flashback and low pressure.
