• If the sealing ring and automatic air vent are exposed to direct high heat, such as that from a hot burner or stovetop, they will
deteriorate rapidly. If direct high heat exposure occurs, replace both of these parts.
• Clean the sealing ring groove in the cover with a brush each time you replace the sealing ring.
• To clean or replace the automatic air vent, push it out of its opening from the top of the cover. After
cleaning it, or when replacing an old one with a new one, reinsert the automatic air vent by pushing the
domed side into its opening from the underside of the cover.
The bottom edge should be fully and evenly seated against the underside of the cover (Fig. F). When properly installed, the small
end of the metal pin will be visible when viewed from the outside of the cover.
• If the automatic air vent is ever forced out of the cover due to excess pressure while canning or cooking, it is important to call the
Presto Customer Service Department at 1-800-877-0441 for assistance. Do not attempt to use the released automatic air vent.
Steam Leakage
If leakage of moisture or steam develops while using your canner, check the following possible causes:
• The formation of a small amount of moisture under the pressure regulator is normal when canning or cooking first begins. This
condensation is a result of the temperature of the pressure regulator being lower than the rest of the canner. If excess condensation
continues, the vent pipe may be loose and should be tightened with an adjustable wrench.
• Leakage between the cover and body is usually caused by shrinkage of the sealing ring after prolonged use. Replace the sealing
ring and the automatic air vent.
• A small amount of steam or moisture may be visible around the automatic air vent when canning or cooking begins. This will stop
when the automatic air vent seals. If the leakage continues, clean, reposition, or replace the automatic air vent.
Do not operate your pressure canner with continual leakage. If the preceding steps do not correct the problem, contact the Presto
Consumer Service Department.
