Can I switch from LP14 orifice to N14 orifice?

Yes, you can switch from an LP14 orifice to an N14 orifice, but it's important to ensure that your equipment is compatible with the new orifice size and that you adjust the gas pressure accordingly. The N14 orifice is typically designed for higher pressure applications, so make sure to consult your equipment's specifications and guidelines. Additionally, any changes should be performed by a qualified technician to ensure safety and compliance with local regulations.
