Porcelain
Porcelain is basically glass. It is durable, easy to clean and heat resistant. Because of these
qualities, it lends itself well to most oven interiors and cooktop surfaces. While durable, it is also
vulnerable to impacts and most sugar-based substances. (Also, be aware that when heated,
some vegetables create sugars and it does not have to be a processed sugar to damage the
porcelain) When heated, sugars will permanently stain or etch most glass surfaces once they
have worked their way into the fabric of the glass. A self-clean cycle will not remove them but a
vinegar-based solution can often neutralize the stain. In order to be most effective:
 Select Convection Bake and preheat the oven for thirty minutes at 350F.
 Add one quart of plain white vinegar to a casserole dish and place on the center rack of the
oven
 Bake for one hour
 Without opening the oven door, cancel the bake cycle and allow oven to stand overnight.
In many cases this will neutralize most white or ashy stains in an oven cell. The oven interior is
generally considered to be a working component rather than a cosmetic component of the oven,
therefore, some staining is considered normal.
Reverse Air Flow
The majority of modern wall ovens and ranges incorporate some sort of internal cooling or
ventilation system. Most of these systems simply allow the oven to breath better during the bake /
broil cycle. Others only turn on a fan during self-clean. Dacor incorporate a reverse airflow cooling
system that is used as both an external and internal cooling system.
At temperatures above 220F. all Dacor ranges and wall ovens will automatically turn on the
Reverse Airflow System. It will run throughout the bake, broil and self clean cycles. Once the
internal temperatures dip below 300F the system will automatically turn off.
Dacor products draw air in through the door handle and from underneath and through the door.
This style of “reverse” airflow allows us to maintain much lower external door, window pack and
control surface temperatures as well as provide a continuous flow of cooler air across the sensitive
electronic controls.
Depending on the model, once the air has circulated through the product it either exits through the
lower exhaust grill or behind the product.
