1 . 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. 

NOTE: The Pressure Dial Gauge can be found in the foam filler

of the carton. It is in a white box.

The pressure regulator acts as a safety device to 

prevent pressure in excess of 15 pounds from

building in the canner. Pressure readings on the 

pressure canner are registered only on the pressure 

dial gauge. 

NOTE: The Pressure Regulator can be found in the top foam filler

of the carton. It is in a bag identified with the words “P

ressure

 

r

egulator

 e

nclosed

”.

The vent pipe is the primary pressure relief valve 

and will release pressure in excess of 15 pounds.

The pressure regulator sits loosely on the vent 

pipe.

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.

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.

The  sealing ring  fits  into  the  canner cover  and

forms a pressure-tight seal between the cover and 

body during canning and cooking.

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/or clogged and pressure cannot be released normally 

through the vent pipe.

The canning-cooking rack is placed in the bottom 

of the canner to hold jars off the bottom of the unit 

while canning. When cooking, the rack is used for 

steaming foods. It can also be used to hold foods 

such as vegetables out of the cooking liquid which allows several

foods to be cooked at the same time without an intermingling 

of flavors. When it is desirable to blend flavors, do not use the

canning-cooking rack. The canning-cooking rack must always be 

used when canning.

 1.   Remove the sealing ring by simply pulling it from the sealing ring groove.
 2.  Wash the cover, body, and sealing ring with hot, sudsy water to remove any 

manufacturing oils. Rinse all parts with warm water and dry.

3.  Replace the sealing ring in the sealing ring groove, making certain to fit the ring

under the stop tab located on the inside rim of the cover (Fig. A).

  4.   The sealing ring is prelubricated. If necessary, to help make the cover easier to 

open and close, a very light coating of cooking oil may be applied to the sealing 

ring and underside of the body lugs (Fig. B). The cover should open and close

easily when following the instructions on page 5, step 6.
