There no set height. All grills are different and cook at wide range of temperatures. Customers who wish to grill under Suntuf or Palruf must be certain that the maximum temperature above the grill never exceeds 212°F for Suntuf and 122°F for Palruf.
These temperatures represent the maximum service temperature for both products. If the products are subjected to temperatures higher than these, the product warranty will be voided and damage can occur to the panels.
