Product review (1 stars): No LP Orifice in the LP Orifice conversion kit
The kit comes as a set for butane and propane.  My kit had 2 butane orifice'.  I purchased the kit in advance of building a new home on propane, which took almost a year.  This discovery wasn't made until then and it was too late to return. The package says "Whirlpool Corporation Factory Certified Parts", so this would be their screw-up, not the seller.  Sorry seller, I don't have a way to rate Whirlpool.
