Weil McLain 381-354-535 Conversion Kit 322838-753 this foldback heating element providesThe Weil McLain 381 354 535 is a performance critical natural gas high altitude conversion kit designed to calibrate combustion parameters for hydronic systems operating in low oxygen environments. At elevations above 2,000 feet, reduced air density necessitates precise adjustments to the fuel to air ratio to prevent incomplete combustion and soot accumulation. This kit modifies the gas input and burner performance to ensure atmospheric or forced
