Common Questions

What is the drill size for the 323267-702?
This orifice is a standard #43 drill size, calibrated specifically for natural gas applications at sea level or standard altitudes.

Can I use this orifice for a propane (LP) conversion?
No, the 323267-702 is specifically for natural gas. Propane conversions require a smaller orifice size to account for the higher energy density and pressure of LP gas.

How do I verify if this fits my specific Carrier furnace model?
Check the rating plate on your furnace for the required orifice size or cross-reference the 323267-702 or LH32DB202 part numbers in the unit's illustrated parts list.
