Wanting to purchase a new oven/stove however the product specs are telling me I need to check the "gas bias" in my area before purchasing the product. What is gas bias & what does it mean? Cheers in advance

Hi pearce and welcome, are you by chance in the U.K. Maybe they want you to be sure gas is available in you area? Just a guess.

Possibly refers to cost of NG or Propane vs. Electricity
