I am remodelling my kitchen and want to place a gas or dual fuel range near an existing window. My contractor says there is a minimum clearance of 30" required between a gas range and a window -is this correct? This seems excessive to me.

The building code in my town doesn't specify any minimum but instead says appliances must be installed as per the installation guide with the appliance. However none of the installation guides I have checked so far mention anything about clearances between a range and a window.

Thanks for your help.
