Heater won't turn on
Hi! I have a 2008 1508T Hi Lo. It was supplied with an Atwood Hydro Flame furnace (I think Model 7900). In the Hi Lo owner's manual, it simply says that the furnace runs on DC current and to simply open up the gas supply, turn the thermostat to "on", turn up the temperature, and the furnace will ignite automatically. I'm having no success with this. The only accompanying paperwork for the furnace are installation instructions. Can someone please help me out?!
