I think a previous poster was spot-on, Les. You just needed to get the fuel up where it belongs, and that took a few cycling and resting efforts.
Glad you are back in business, although you are correct that you need to let it stay on for awhile and cycle a day or two to be sure. If you are going to the Oregon rallies next month, have Orman, John Carillo, or an AquaHot tech check things out just to be sure all is up to snuff, and lessen the liklihood of losing heat some time when you really need it.
