How do I install and use it?

2. Insert the 4″ stem through the hole, and secure with the nut included (or use an installation kit for thin metal)

What are the advantages and considerations?
Advantages:

• Ensure the stem is fully in the cooking chamber and doesn’t touch food or flame.

• For thin metal lids, you may need an installation kit to ensure a proper seal.
• As with all analog thermometers, occasional calibration checks are recommended.
