We have a 08 Wildwood Sport. If you have turned the gas on at the tanks and you turn up the thermostat the unit should automatically light. You should hear the blower fan come on to vent any fumes from the system before the igniter attempts to light the furnace. You should be able to hear the "clicking" sound from outside near the exhaust vent for the furnace. If you dont hear the clicking noise and you dont feel the heat shortly after after it is turned on then you might need to have someone check the system.
Others may be able to comment on something I forgot to mention.
