RV Repair: Suburban Heater, argosy, dunham

Question
I recently finished refurbishing a 1976 Argosy travel trailer.  I remover the working heater, then re-installed it agter the work.  Now, it runs (fan) but the propane won't ignite.  According to the manufacturer:"yjr igniter is in lockout and needs to be reset"  Of course, they want me to take it somewhere.  Can you give me a hint as to how to accomplish this?  Thanks, Bob dunham

Answer
Resetting the unit simply involves removing all power from the unit for several minutes. Try that, if it doesn't work, reply with some more information. Did you complete the work? What was done to the furnace? Do you here a 'click' as the valve opens? Is the igniter sparking at all?
