Floor Protection for Fireplace Installations

Do not assume that your fireplace hearth is completely

noncombustible.
Many fireplace hearths do not meet the “completely

noncombustible” requirement because the brick or

concrete in front of the fireplace opening is supported

by heavy wood framing. (Fig. 13) Because heat passes

through brick or concrete readily, it can easily pass

through to the wood. As a result, such fireplace hearths

can be a fire hazard and are considered a combustible

floor.
Keep in mind, also, that many raised hearths will extend

less than the required clearance from the front of the

heater when it is installed. In such cases, sufficient

floor protection as described above must be added in

front of the hearth to satisfy the minimum floor protector

requirement from the front of the stove: 16” (406mm)

from the front in the United States and 18” (459mm)

from the front in Canada.
Hearth rugs do not satisfy the requirements for floor

protection.
Fireplace installations also have special clearance

requirements to the side walls, side decorative trim, and

fireplace mantel. This information follows in the section
on Fireplace and Mantel Trim Shields.

Keep the Stove a Safe Distance from Sur-

rounding Materials

Both a stove and its chimney connector radiate heat in

all directions when operating, and dangerous overheat-

ing of nearby combustible materials can occur if they

are too close to the heat. A safe installation requires

that adequate clearance be maintained between the

hot stove and its connector and nearby combustibles.
Clearance is the distance between either your stove

(measured from the bottom edge of the stoveʼs top

plate) or chimney connector, and nearby walls, floors,

the ceiling, and any other fixed combustible surface.

Your stove has special clearance requirements that

have been established after careful research and test-

ing to UL and ULC standards. These clearance require-

ments must be strictly observed.
In addition, furnishings and other combustible materi-

als must be kept away from the stove as well. In gen-

eral, a distance of 48” (1219mm) must be maintained

between the stove and moveable combustible items

such as drying clothes, furniture, newspapers, firewood,

etc. Keeping those clearance areas empty assures that
nearby surfaces and objects will not overheat.

Reducing Clearances Safely with Shields

Clearance requirements are established to meet every

installation possibility, and they involve the combination

of four basic variables:

When the stove and chimney connector have no

listed heat shield mounted on them.

When the stove and chimney connector have a

listed heat shield mounted on them.

When the wall has no listed heat shield mounted

on it.

When the wall has a heat shield mounted on it.
