Can I use the natural-gas valve (00-410841-00001) on LP?

This page answers one question for buyers, maintenance technicians and parts distributors: can 00-410841-00001 be used in place of 00-410841-00002 in a commercial fryer? It is a part-number comparison, not a sales page — nothing here is offered for sale and no price is quoted.

Source basis: OEM valve documentation.. See Sources, method and reliability for what is verified and what is not.

Short answer: No, not without the LP conversion kit. The LP version (00-410841-00002) uses the same body with LP conversion kit 51-1470. A natural-gas valve running on LP will not regulate correctly and is a safety hazard.
