The pilot light on the furnace won't lite. I checked the manual for this year and it doesn't mention the pilot light or much about gas use in general. I tried starting it about three different times throughout the day, but never had any luck. The procedure I used was to turn the power selector to gas, turned the gas knob to on - high, held it down and proceeded to punch in the red button about 15 times. It never lit... The heater blower inside the camper turned on, but it blew cold air. Any ideas of what I can do?
