I am installing an 19000 btu 12v lp heater in my trailer and my question is - on the back of the heater it says elevation 0-4500 . Will this work in places like centenial , TML or do i need to put a smaller orafice in the heater or can i put an adjustable regulator on the tank to accomadate lo and high altitude at the same time ? Or will it simply not be a problem ? Anyone who has overcome this problem , your input would be greatly appreciated . Thanks
