Diagnosis
The included metal rack is not a weird extra part; it's a critical safety component for pressure canning. Its primary function is to prevent direct jar-to-metal contact and to facilitate proper heat circulation and pressure equalization.
How to Fix It
To use the rack correctly:
- Before filling the canner with water, place the rack flat on the bottom of the canner pot.
- Add the recommended amount of water (usually 2-3 inches for a 22-quart model) so it covers the rack.
- Arrange your prepared, warm jars on the rack, ensuring they are stable and not touching the sides of the canner or each other.
- Proceed with your canning recipe. The rack elevates the jars, allowing water to circulate underneath during processing and creating a buffer against the intense, direct heat of the aluminum base.
If That Didn't Work
If your rack is missing or damaged, do not operate the canner without it. Contact T-fal customer service for a replacement part specific to your 22-quart model. Using a substitute like a towel or makeshift trivet is unsafe as it can block steam vents, impede circulation, or fail under pressure and heat.
Heads Up
Never place jars directly on the canner's bottom. The rapid, uneven heating can cause glass jars to crack or shatter (thermal shock), creating a dangerous situation with boiling contents and pressure. Always use the rack for every batch.
