DELIMING THE CAVITY (ELECTRIC AND GAS UNITS)
 As with all steam related products, water fi ltration and regular fi lter replacements coupled with 
routine deliming are required. Your local Vulcan Service offi ce can recommend a water treatment system 
to meet the needs of your local water conditions. Contact your local Vulcan Service representative for 
water treatment offerings.
Oven cavity deliming should be done on a regular basis. The frequency depends on oven use, quality 
of the local water supply and what type of water treatment system is used. Even with the use of a water 
treatment system, periodic deliming of the oven cavity is still required. If lime scale build up becomes 
visibly noticeable, then the oven cavity deliming should be performed.
 Deliming should only be performed on a cool oven after a clean cycle has occurred.
NOTE:  All components inside the oven cavity, such as the heating elements, racks, and rack guides can 
be sprayed with white vinegar or a deliming product.  It is not recommended to spray interior glass with 
deliming product and immediate rinsing with water at least 3 times is suggested should it come in contact 
with the glass.  Deliming solution may cause the surface of glass to etch which leads to a cloudy look on 
the glass that cannot be removed.
  1. Remove wire racks, rack guides and fan guard for separate deliming following the same procedures 
as below for the cavity.
  2. Spray the entire oven cavity with white vinegar (full strength) and let it stand for no longer than 15 
minutes. Or use a deliming product. When using a deliming product other than white vinegar, follow 
the directions on the product label.
  3. Rinse entire cavity thoroughly with spray hose ensuring a deep rinse where all deliming chemical 
was sprayed.
  4. Rinse door gasket & glass with fresh cloth moistened with warm water.
  5. Install fan guard, rack guides and wire racks after delime and rinse process is completed for those 
parts.
  6. Leave the door open overnight to vent cavity.
