Cooking Appliance Installation & Repair Specialists.

What are hot-zones ?

These are clearance areas around the appliances that should be free of
..... Any flammable materials .....
..... Any objects that can impinge on the burners ability to operate .....

Typically these are areas to the side, to the rear and above gas hobs.
They also cover areas around range cookers, high level grills and built in ovens.

No gas cooking appliance should be installed where these clearance zones can not be achieved.

The following diagrams reflect the Gas regulation requirements for these Hot-Zones.
Manufacturers instructions will always comply with these regulations but should their specifications differ, it is the manufacturers instructions that take precedence.

..... So if .....
The gas regulation states a minimum of 600mm
The manufacturers instructions state a minimum of 700mm,
700mm is the minimum clearance requirement.
