I just de-winterized my Campsite Ultra 26th and when I push on the power button on the tankless hot water heater, nothing happens. I checked all breakers and I don't see one for the water heater. My propane is on. Is it only a propane heater? If so, where would I light a pilot? When I got the initial walk through at the dealer, the tech didn't show me any pilot lighting if I remember correctly. I think he already had it on and was producing hot water. Can someone answer this question for me? Thanks in advance.
