Question DetailsAsked on 3/7/2012

PJ
Does a self-cleaning oven need a special floor, or will the old vinyl flooring be enough?

The manual says it needs a heat proof floor. Is that different from any other floor under a regular oven?

The heat from the oven can warp the vinyl and cause the glue to let go, even possibly making the glue put off fumes that could be hazardous. The easiest remedy if not on a concrete foundation is to remove the vinyl and place a thin layer of stainless steel sheeting under the new oven. It will reflect much of the heat and won't be damaged or put off fumes from the oven's heat. If on a concrete slab simply remove the vinyl and adhesive from under the area the oven sits. Cut it straight across the inside lip of the front skirting or door of the oven and no one will ever see it's missing under there. The other thing you can do is lay porcelain tile. Of course this will cost more and you'll want to do the entire kitchen but you will have consistent flooring throughout the space.

Thanks, I'll go to the hardware store. The manual says it should withstand 200 degrees. I am not sure how the vinyl floor measures up to that.

Generally, if installed with the original feet, it should have enough air clearance to be OK - I know I have never seen a problem with it on linoleum, though I have seen vinyl square flooring bleed asphalt adhesive at the joints under dishwashers and dryers and stoves. Checking a couple of linoleum manufacturer sites I found 80 and 90 and 100 degree high-end recommendations to avoid damage - which I guess means do not install linoleum in houses without air conditioning ? However, I did find an MSDS stating the boiling point is about 220 degrees, so if the stove does turn out 200 degrees in the self-cleaning cycle, it would certainly ruin the flooring and could turn it gummy.

Two other things I have seen done in this cases under high-temperature commercial ovens (like under pizza ovens) is cutting concrete hardiboard (concrete backer board) to fit, or lay down a layer of thin paving blocks, or a scrap of diamond plate decking - put a trim strip at the front for looks. Of course, this raises the stove above countertop a bit, but a lot cheaper than that size piece of sheet metal.

PS - I doubt you will find sheet metal, at least economically, at a hardware store. You will have to go to a sheet metal fabricator or a steel supply company. Galvanized (which will rust eventually though you could rustoleum it for longer life) should cost about $40-50 for that size sheet - stainless probably more like $150 for something like a 30x36 inch foot piece of 16 gauge. Plus about $10-20 for shearing to the size you need.

One other consideration - since the combustion point of plywood is about 400-500 degrees depending on glue and treatment, you could probably just slip a piece of thin plywood like luan under there to protect the flooring - that certainly gives you a good leeway on the tempeature. Consumer stoves have to be safe for putting on wood flooring, so that would work for you - if you wanted you could get fancy and put hardwood flooring under there, even.
