Hi folks, hoping for a little knowledge. Water heater on 99 Coleman Niagara. Trying to light this thing for first time, believe it sat around for years without being used. First of all the anode as I found it was disintegrated. got a new one and washed tank out dozens of times with white chalky substance coming out. finally got it clean. Tried a bunch of times unsuccessfully to light pilot, took all apart blew everything out, got a lot of junk out of bottom of burner compartment. Everything seems to be clean. Finally got pilot to light and stay on but when I switch to on position I either get a pop and it goes out or I hear gas running but no flame. Also no idea if related but I get no gas to outside stove, I push the pin in on connector and hear and smell nothing. Furnace lights and inside stove lights. Confused and don't understand if some kind of regulator problem affecting all three or if totally unrelated. Imagine RV repair shop would be costly so looking for a little help. Otherwise pup in great shape and ready to roll. Thanks.
