Suburban NT12SE Furnace Upgrade
I have a 1995 dodge Sportsmobile Van. It has a Suburban 12,000 BTU heater in it now, model NT12SE. I travel in cold climates and have been looking to upgrade to a 19,000 BTU heater that is the same model,NT20SE. Doing some research I have found that the only difference in the two heaters is the Orifice size in the burner. Burner, gas valve, fan, housing, clearances, exhaust ports are all the same part number. To buy a larger heater is around $500 but I bought the larger orifice for $6. Anyone else use this modification?
