Your canner is a special, large capacity pressure vessel designed for
home canning a wide variety of fruits, vegetables, meats, poultry, fish,
and seafood. The canner uses pressure to achieve the high temperatures
required for safely processing foods while canning.
The United States Department of Agriculture (USDA) recommends the
pressure canner as the only safe method for canning low-acid foods:
vegetables, meats, poultry, fish, and seafood.
Become familiar with the various parts of the canner (Fig. A). Do not
attempt to use your pressure canner before reading the instructions on
pages 4 and 5.
Introduction to Parts
Note: The parts shown are not to scale.
Œ
Overpressure Plug
The black, rubber overpressure plug is located in the canner cover. It will automatically pop out and release steam in
case the vent pipe becomes blocked and pressure cannot be released normally through the vent pipe. Replace
the overpressure plug every time you replace the sealing ring. This should be at least every 3 years, or sooner
if they become hard or inflexible. Use only genuine Presto
Pressure Dial Gauge
The pressure dial gauge registers pressure in pounds per square inch, or PSI. The pointer moves around
the dial indicating the pressure within the unit. Pressure can be controlled and maintained by adjusting the
heat setting on your stove. The gauge is attached to the cover with a soft, black, molded rubber adapter. The
gauge sits in the center of the cover.
A new adaptor should be installed when the old one becomes hard or inflexible. Install the new adaptor by
pushing the small end up through the opening from the underside of the cover. The large lip should
fit flat against the underside of the cover .
Pressure Regulator
Ž
The pressure regulator acts as a safety device to prevent pressure in excess of 15 pounds from
building in the canner. Pressure readings are registered only on the pressure dial gauge. The
replacement regulator (
Ž
A) has a different look but functions in the same way as the original one.
Vent Pipe
The vent pipe is the primary pressure relief valve and works in conjunction with the pressure regulator
to release pressure in excess of 15 pounds. The pressure regulator sits loosely on the vent pipe. The
replacement vent pipe (
A) has a different look but functions in the same way as the original one.
Air Vent/Cover Lock
The air vent/cover lock automatically vents, or exhausts, air from the canner and acts as a visual indication
of pressure in the canner. The small gasket must be in place for the air vent/cover lock to seal completely.
‘
Locking Bracket
The locking bracket on the inside of the canner body engages with the air vent/cover lock to prevent the
cover from being opened when there is pressure in the unit.
Sealing Ring
’
The sealing ring fits into the canner cover and forms a pressure-tight seal between
the cover and the body during canning. Replace the sealing ring at least every 3
years. Use only genuine Presto
“
Canning Rack
The rack is placed in the bottom of the pressure canner to hold the jars off the
bottom of the canner while canning. Always use the rack as the jars may break if
set directly on the bottom of the canner.
