How To Install Free Standing Wood Stove

WHAT SHOULD I PLACE A STOVE ON?For heaters set on legs or pedestals that provide not less than six inches of ventilated space beneath the fire chamber or base of the apparatus, apply closely spaced solid masonry bricks or blocks non less than 2 inches thick. The meridian surface of the bricks should be covered with canvass metal not less than 24-gauge.

The flooring protection should extend not less than 18 inches beyond the appliance on all sides. A floor protector listed by a recognized testing laboratory such as UL may be used if installed in accordance with the installation instructions.

HOW FAR SHOULD A Wood STOVE Be FROM AN UNPROTECTED WALL OR Flammable MATERIAL?The standard clearance for appliances installed in rooms which are big in comparing to the size of the appliance is 36 inches from the top, sizes, back or front of the appliance. Otherwise, install according to the manufacturer'southward instructions.

IS A MASONRY VENEER COVERED WALL CONSIDERED SAFE FOR REDUCED CLEARANCE? No! National Fire Protection Association (NFPA) codes let reduced clearances to flammable walls if adequate protection is provided. Sheetrock, sheet metal, masonry veneer and other thin or not-insulating materials placed directly against walls give little protection. These materials bear heat very well; they will be nearly every bit hot on their back sides every bit they are on their exposed sides.

Reduced clearances are acceptable for the following:

an engineered protection arrangement approved past the inspecting authority having jurisdiction
products and materials listed for protection purposes
a non-flammable protector mounted an inch or more abroad from a combustible wall to let free apportionment of air behind it

The reduction is specified by NFPA and virtually codes. For instance, when required clearance with no protection is 36 inches, a 3 1/2-inch-thick masonry wall with ventilated air space used equally a wall protector, reduces clearance past maximum of 66 pct, to 12 inches from the combustible wall.

Can RADIATING-TYPE Wood STOVES Always Exist INSTALLED LESS THAN 36 INCHES FROM COMBUSTIBLES?

Yep.

If a UL-listed stove has a estrus shield attached, the clearance can be reduced as specified. Or build a oestrus shield to be mounted ane inch off the wall on non-combustible spacers. To reduce the standard clearance to 12 inches, the heat shield should be of 28-gauge canvas metallic, mounted off the flooring to provide unrestricted apportionment of air between shield and wall (run across Figure i).

WHAT SIZE HEAT SHIELD DO I NEED?Whatsoever area within 36 inches of the wood stove should exist covered every bit shown in Figure 2.

DOES A STOVEPIPE NEED SPECIAL CLEARANCE TO COMBUSTIBLES? Yeah. Clearance should be three times the diameter of the pipe, e.g., a 6-inch pipage needs xviii inches of clearance. Rut shields may be used to reduce the clearance by the same ratio as for the stove. For example, with canvass metal you tin can reduce the clearance by two-thirds, from xviii inches to 6 inches.

HOW Exercise You RUN A STOVEPIPE THROUGH A Combustible WALL OR CEILING? Y'all don't. But if absolutely necessary, the post-obit are canonical methods:

Build a 3.5-inch thick brick masonry wall framed into the flammable wall, with a 12-inch minimum clearance from the clay liner to combustibles.
Use a solid, insulated, listed factory-built chimney, with a 9-inch air infinite to combustibles.
Apply a 24-guess sheet-steel chimney connector with ventilated thimble, plus 6 inches of glass fiber insulation.
Utilise a solid, insulated, listed manufacturing plant-built chimney over a 24-estimate chimney connector, with ane inch of air space, plus 2 inches from outer wall of chimney section and combustibles.

Connectors must also maintain a pitch of at least i/4 inch per human foot from the appliance to the chimney. Avoid sharp turns, which create excessive resistance to the menstruum of flue gases, and support and spike securely with sheet-metal screws, rivets, or other approved means.

CAN You VENT A Woods STOVE AND AN OIL BURNER INTO THE SAME FLUE? No. Each should exist vented into a divide flue. Multiple connections can cause flue gases and sparks to pass from ane flue opening to another, reducing efficiency and igniting unburned gases in the flue.

WHAT Most Manufactory-BUILT CHIMNEYS?They are efficient and easy to install, merely should be UL-listed. Insulated factory-built chimneys minimize soot and creosote buildup because the inner walls warm rapidly. The necessary clearance from combustibles is marked on each section of UL-listed, manufactory-built chimneys.

IS A MASONRY OR METAL FACTORY-BUILT CHIMNEY BEST?Both are prophylactic and durable if synthetic properly and well maintained. Information technology is important to have an insulated chimney, particularly with an airtight wood stove. Interior chimneys are preferable to exterior because they are warmer. Also, round liners are more efficient than rectangular ones. Appearance and price are other considerations.

Tin can YOU USE SINGLE WALL STOVEPIPE FOR AN Outside CHIMNEY? No! Fume pipe was never meant to be used outside. Water and ash form lye that speedily eats away unmarried wall pipe. Too, creosote forms rapidly due to cooling of gases inside the pipe itself.

Tin can I VENT A WOOD STOVE INTO AN UNLINED CHIMNEY? No. All masonry chimneys should have tile liners. Homes built before 1900 often have unlined chimneys, which are hazardous and shouldn't be continued to a wood stove.

WHAT ARE THE SAFETY CONSIDERATIONS THROUGH FIREPLACES?NFPA 211 states the following:

The flue must be no larger than three times the cross-sectional area of the apparatus flue outlet.
The system must be designed and installed and then that information technology tin be inspected and cleaned.
A solid-fuel burning appliance may NOT vent into or through a factory-built fireplace unless information technology has been specifically listed for that purpose.

HOW Loftier SHOULD A CHIMNEY Exist?Information technology should extend at least 3 anxiety above the highest bespeak where it passes through the roof. It should be 2 feet higher than anything within a 10-foot radius, including the roof itself, overhanging trees, side by side buildings, etc.

HOW CAN I Control CREOSOTE?Creosote condenses when stack temperatures drop below 250øF, and then the type of chimney is very important. An insulated one is desirable. A large, closed heater in a small home in a -choked- position will produce creosote regardless of the type of wood burned or its moisture content. Minimize creosote formation by:

Using UL-listed wood-called-for equipment and chimney materials and installing the unit according to manufacturer's instructions.
Proper sizing of chimney and components.
Edifice a small hot burn for a brusk period rather than an "idle" fire over a long period, when temperatures are moderate.
Keeping a hot fire; many manufacturers recommend opening the damper and allowing the stove to burn hot for at least 15 minutes to burn away small-scale amounts of creosote.
Using only well-seasoned hardwoods.
Inspecting your arrangement frequently and learning to operate information technology most efficiently. Clean your chimney accordingly
