Isn't what seems to make the Dometic easier to light after running on 120 ac or 12 volt dc the fact that the hydrogen/ammonia mixture has already begun circulating within the system?

Just hard to imagine that the heat from the heating element  (AC or DC) would contribute enough inadvertent heat to exhaust flue to  aid in flow of fresh air into combustion chamber. Just can't see it  making that much of a difference.
