Help w/ hot water heater I’m in over my head on this one! Just bought my first travel trailer! Her name is Addie (short for Adventurer). I have the electric and water on. She’s stable and level. I filled the fresh water tank (after sanitizing) and have the pump on. I have a propane cylinder connected. Sooooo…. Hot Water heater is next but the instructions I was given don’t really tell me squat!! I see a hot water heater button where the pump on/off switch and where the tank levels/battery level is hanging on the wall. I just be scared to push that button but I wanted to make sure I didn’t miss anything and ruin the pump or the heater. I do t know about the furnace either. Gas pretty much makes me nervous with the exception of a gas range. I have a pic of the furnace- it’s filthy and I see no power? Pic attached! Toni & Addie
