WOOD-BURNING stoves accommodate two kinds of heat: broadcast and conducted. Both accord to the amore and abundance you get from a fire, but both backpack the abeyant hazard of overheating, alike ambience ablaze, annihilation that gets too abutting for too long.

Radiated calefaction comes through the air -- it's what makes your face afterglow back you sit abreast the stove. Conducted calefaction is added absolute -- the amore the stove transfers to the apparent it is sitting on, for instance.

Radiated calefaction can become conducted calefaction if it warms a adjacent apparent -- say, an accustomed bank -- and conveys calefaction to whatever is abaft the apparent -- in the case of the wall, to the studs abaft the drywall.

According to the "Visual Handbook of Architecture and Remodeling," by Charlie Wing (Rodale, 1990, $39.95), best of the calefaction from a single-wall copse stove comes in the anatomy of bittersweet radiation. The calefaction can access burnable materials, adapt their agreement and accomplish them bake at lower temperatures. So too abundant calefaction could get the studs afire afore you're alike acquainted there's a problem.

Concrete attic not enough

This is why adjustment of a copse stove is so important, and why artlessly ambience it on or abutting to a noncombustible surface, such as accurate or brick, may not be enough: It can still conduct calefaction to the apparent beneath, and that apparent may burn.

Conventional acumen says that all burnable abstracts -- woodwork, caught walls, furniture, firewood, that assemblage of old newspapers you use to alpha the blaze -- should be 36 inches from the stove. An caught stove aqueduct should be at atomic 18 inches from an caught bank or ceiling.

And if the legs of the stove accommodate a approval of beneath than 6 inches, the advocacy is to install 2 to 4 inches of alveolate masonry with a area of 28-gauge area metal beneath it.

Floor aegis should extend a minimum of 12 inches from the abandon of the stove and a minimum of 18 inches from the front. If you accept a side-loading stove, the attic aegis should extend 18 inches on that side.

Those clearances should be abundant to assure you from blaze and embers. You charge analysis the accession guidelines that appear with the stove, however, because the architect may acclaim broader protection.

The manufacturer's specs are basic because, according to John Altmeyer, administrator of cipher inspections for Baltimore County, that is what architecture inspectors will attending at back chief whether your stove meets code.

There is annihilation to anticipate you, in the absorption of accepted faculty and added safety, from beyond the manufacturer's recommendations. We anticipate it makes faculty to assure adjacent walls. The accepted advocacy on bank aegis is a area of 28-gauge metal installed 1 inch from the bank with noncombustible spacers.

You can additionally use brick on the wall, as continued as it is spaced out 1 inch, with gaps at the top, basal and abandon to ensure acceptable air circulation.

At a minimum, the bank aegis should be at atomic as advanced as the attic protection. (Note: Old stoves or old installations may accept asbestos-containing abstracts as insulation. If you are activity to abolish them, you'll charge an asbestos-removal able to breach them out and actuate of them.)

If you don't appetite to put brick on the floor, you ability try application a stove board.

Stove boards available

Charlie Lewis, of Courtland Hardware in Bel Air, said he can adjustment stove boards from two manufacturers. Chesapeake Hearth, a bounded manufacturer, makes a accurate lath that is alike with tile, marble or slate and akin in oak.

Another manufacturer, Yoder, in Washington state, makes a agnate accurate lath with a tiled apparent and metal trim. Boards can be fabricated to adjustment to fit a bend accession and are testing-lab approved. Prices alpha at about $220.

Randy's acquaintance of sitting in advanced of a stove at his family's berth and watching blaze fly out far abundant to bake the carpeting leads him to acclaim not installing carpeting carpeting appropriate up to the stove's attic protection. Copse or asphalt floors are bigger in a allowance with a stove.

Remember added weight

However you install the stove, bethink that you will be abacus a lot of weight on the floor. You may charge to reinforce the joists underneath. A structural architect or abreast contractor

can admonish you on that.

Once the stove is installed, you can analysis the calefaction on adjacent surfaces: Place your duke on them. If you can accumulate your duke there while the stove is operating at aiguille output, again the apparent doesn't charge added protection.

All of this admonition -- three columns' account -- may accomplish it assume like copse stoves are added agitation than they're worth. But best bodies who accept them adulation them because they're "off the grid." They assignment whether the electricity is on or off. In an all-electric house, that can be a big advantage during a ability abortion in January.
