2. FLOOR PROTECTION.

Acombustible floor must be protected from the radi-

ant heat given off by the unit and from the inevitable

spark or falling ember. This includes almost any floor

surface. Only a solid masonry or concrete floor ade-

quately covering the distance around the unit is

acceptable. Alayer of thin brick or ceramic tile over a

combustible floor is insufficient. To protect your floor,

it is necessary to install a floor protector of one layer

of 3/8” non-combustible millboard having a thermal

conductivity of K = 0.84 BTU IN/FTHr F, or an equally

thick UL listed floor protector. The required dimen-

sions of floor protector vary according to the length of

chimney connector as shown. If you construct your

own floor protector with the one layer of millboard, we

suggest that it be covered by one sheet of 24-gauge,

or heavier, galvanized sheet metal. It can then be

covered with ceramic tile, or thin brick, and framed to

protect the millboard and give it a finished look.

NOTE: The minimum Floor Protector Size for the Model 400

Woodstove is 31” wide x 39” deep.

Any horizontal length of chimney connector pipe must

also have the floor protector beneath it and extending

2” on each side of the pipe. The required floor pro-

tector size for Model 400 is 31” x 39”. Refer to

Figures 3a and 3b.

Floor Protection

NOTE: Dotted line indicates additional floor

protection required on through-the-wall

chimney installation. Floor protection must

extend behind the stove to the rear wall.

NOTE: In calculating equivalent thickness

of alternate materials, the following formula

should be used:

One layer of 3/8” (0.375 inch) thick mill-

board has a K factor of
