fireproof backing for stove

[schoonerdog]

Our stove sits against a formica backing and has charred a little over the last 9 years, is there a fireproof insulative backing that I can put behind the oven and then a sheet of stainless steel over top as facade?

[donradcliffe]

The stainless sheet alone should do fine if you leave a little (3/8") air gap between it and the wall, with the top and bottom open for natural circulation.

Asbestos sheet or fabric. So long as you are not breathing it you will be fine. Fiberglass tape works well as a heat insulator.

I think you'll find asbestos to be a material hard to find for the right reasons. You could also use a cement based board like they use on exterior building siding (Hardy board) or in a bathroom shower. Stainless with an airspace works well enough for heating stoves should be fine between stove and wood or other material. It has the lowest weight as well.

That makes sense for the stainless, giving it a small space behind.

we purchased a sheet of fireboard at Home Depot and covered it with stainless and used SS spacers to hold it about a 1/4 inch off the wall and had no issues for years.

Most codes require that non-combustible (sheet metal) stove heat shields be spaced at least 7/8" off the combustible wall, be open top & bottom (air circulation), and be supported on non-combustible spacers located at the margins of the shield (no closer than 8" to centre of stove). They should extend well beyond the stove (20" top & 18" sides).

::nod:: Gord has it pretty exactly.

I walked over to the commercial boat yard and found a machine shop and asked if they might have any ideas. They thought sheet metal would be best, but they happened to have some scrap 3/8" aluminum plate...

So I now have the most amazing heat shield anyone has ever seen, with a machine bevel on the edges, for $20.

Aloha Amgine,
Can you send us a digital photo?
Thanks,

::embarrassed blush:: Sure, as soon as I get some film, shoot it, and develop it. I haven't a digital camera other than a phone one which doesn't speak Canadian (US cell in Canada.)

What am I missing?
Is this for the galley stove?
If so...I'll assume it gimbaled, and thus has a space around it.
If this barrier is required on the bottom and back...why is not necessary on the sides as well?
What exactly are we protecting against...is it spilled flaming oil....I'm assuming this is a gas range.

James--You're missing something. His boat is a St. Francis 44--a Cat--hence, no gimbals.

[James S]

Yeh...that’s missing something big!!
OK, so if its not gimbaled then its closer to the cabinet work, the insulation in the stove is not sufficient to protect the surrounding area...Is that it?

Mine is gimbaled...I have SS cladding directly on the cabinetry on either side and the bottom....the back is separated by a couple inches from the side of the hull and extends well above the range...is that acceptable or do the specs Gord notes still apply?

[Amgine]

Mmm... language issue for me, too. I immediately was thinking of a heating stove, which is what my plate is behind. (Not, now that I think about it, that it would really matter. This much metal would probably work for that situation as well.)

Aloha Amgine,
No need to be embarrassed. Just thought you might already have a photo. No problems. I've got a good imagination. I thought of heating stove too instead of cooking stove.
Kind regards,
JohnL
