Looking for input from construction/handy mags. I'm not particularly well versed in construction and everyone knows this is the place the get answers.
Here's my scenario:
When my kitchen was constructed (before I owned the house), the builder installed counters with ~2 1/4" nosing. He neglected to account for that when building the cabinets. To avoid having the top drawers hit the nosing, he installed an extra layer of plywood to lift the counters up. The counters are ~37" from the floor. The upper cabinets were installed at the normal height (54" from the floor). The space between the countertops and the bottom of the upper cabinets is ~17".
This creates an issue when it comes to our stove installation. From my local building code:
9.10.22.3. Protection around Cooktops
1. Except as provided in sentences 2 and 3, combustible wall framing, finishes or cabinets within 450mm of the area where the cooktop is to be located shall be protected above the level of the heating elements or burners by material providing a fire resistance at least equal to that provided by a 9.5mm thickness of gypsum board.
...
3. ...cabinetry located not less than 450mm above the level of the heating elements or burners need not be protected as described in sentence 1.
This applies to electric or gas stoves. Since moving in, I have had my stove installed flush with the countertops and accepted what I perceive to be a low risk. I am now selling the house and the buyers are concerned about this. I am looking for a practical solution. Options I see include:
1. Lower the stove (it has adjustable legs) so that the burners are the required 450mm (~18") from the cabinets. They would then sit below the tops of the counters, with only the edge of the countertops exposed. The counters are corian and as far as I can gather, that is not a combustible material. The local gas inspector insists that the stove cannot sit lower than flush with the counters though, regardless of my arguing. So this one is pretty much out.
2. Replace the countertops. This is probably the way Mike Holmes would do it, but it's big money and the house is only 3 years old.
3. Remove countertops and cut off the nosing, add a nice bevel and polish smooth. Remove spacer plywood and reinstall counters. Add trim at bottom of backsplash. Not sure the counters would come out in one piece. Also would require a fine touch on the countertop cutting, beveling, etc. Not sure this is even practical.
4. Raise the upper cabinets to get the required clearance. I am pursuing this option with local finishing carpenters. Tricky part will be taking things apart without damage as well as dealing with the large uninterrupted panel next to the fridge that runs from floor to tip of upper cabinets. I'm not certain where the cabinets are from (builder isn't around) so finding pieces in matching stain could be tricky. Also will leave a gap in the backsplash that will require fixing and the upper cabinets would be too high. Medium money.
5. Add some "heat shield" to the bottom of the cabinets in the vicinity of the stove. Convince the inspector that this satisfies the intent of the code.
While I have more than the required clearance above the stove (750mm or ~30"), there is a clause in the code that allows the clearance directly above the cooktop to be reduced if their is either a range hood or the cabinets "are protected by asbestos millboard not less than 6mm thick, covered by sheet metal not less than 0.33mm thick. ". While I don't need to apply this directly above the stove, I feel like something like this should be able to be installed to protect the cabinets adjacent to the stove in the event of a grease fire. I haven't found much yet in my online sleuthing. I called a local woodstove shop and they suggested cementboard as a product typically installed to reduce the required clearance around woodstoves. I'm thinking of a piece of cementboard (same as millboard?) wrapped in custom cut, bent and painted sheetmetal would do the trick and probably not look too awful. I also saw these, which are intended for wood stoves, but I thought maybe they could be cut to fit, leaving the uncut edges facing out. I'm going to call the mfr. and inquire.
Wondering if anyone has dealt with this issue or has any thoughts. Need a solution that satisfies the local inspector (who doesn't have much to offer in the way of suggestions) as well as the buyers of our house, but doesn't break the bank. Thanks in advance.
