This is waaaaay outside my area of expertise (doors), but I have a question about my own kitchen. I just replaced the appliances, which includes a microwave that goes over the stove. I was curious about whether we had enough clearance above the stove to the bottom of the microwave. I looked it up in the 2009 IRC:
G2447.5 (623.7) Vertical clearance above cooking top. Household cooking appliances shall have a vertical clearance above the cooking top of not less than 30 inches (760 mm) to combustible material and metal cabinets. A minimum clearance of 24 inches (610 mm) is permitted where one of the following is installed:
1. The underside of the combustible material or metal cabinet above the cooking top is protected with not less than 1/4 inch (6 mm) thick insulating millboard covered with sheet metal not less than 0.0122 inch (0.3 mm) thick.
2. A metal ventilating hood constructed of sheet metal not less than 0.0122 inch (0.3 mm) thick is installed above the cooking top with a clearance of not less than 1/4 inch (6 mm) between the hood and the underside of the combustible material or metal cabinet. The hood shall have a width not less than the width of the appliance and shall be centered over the appliance.
3. A listed cooking appliance or microwave oven is installed over a listed cooking appliance and in compliance with the terms of the manufacturer’s installation instructions for the upper appliance.
G2447.5 says a minimum of 24" where one of the following is installed and we have condition #3. The manufacturer's instructions show 30" minimum from the top of the stove to the underside of the cabinet above the microwave. We have 32 1/4", which would put the underside of the microwave at 15 7/8" above the stove. Is this enough? I just want to make sure that the 24" doesn't apply to the distance from the stove to the microwave.
