Hi, im new to this forum. I had some questions about my 1996 aerolite . I bought it used from a dealership and they were so busy they did not have time to show me how to use it. I figured out how to use the pluming but i dont know to use my furnace. anybody know? I tried to turn the propane tanks on and went to the furnace and turned it to pilot and clicked the red ignitor and got nothing. one propane tank is empty and the other is very low but has a little. think that may be the problem or is there something else im missing ?
