How To Determine

If Alternate Floor

Protection Materials Are

Acceptable

The specifi ed fl oor protector should be 1/2” (13mm) thick material with a k-factor of 20.07.

The proposed alternative is 4” (102mm) brick with a C-factor of 1.25 over 1/8” (3mm) mineral board with a k-factor of 0.29.

1)Carefully select the proper location for heat circulation,aesthetics,chimneyobstructions and clearance to side wall(s). With proper pre-planning, a slight adjustment of a few inches can save considerable time and expense later during construction and assembly.

2)Carefullyconsiderthepositionofthefireplace opening with respect to the location of adjacent or nearby stairwells, bath or kitchen exhaust fans and/or return air registers for forced air furnaces/air conditioners that could cause a smoking fi replace condition if the house is tightly insulated.

3)Fireplace must be anchored to the framing to prevent movement or rocking; use the nailing strips which have been supplied. The nailing strips are installed to the side of the unit and to the front side of the 2 x 4 or 2 x 6.

NOTE: Hearth must have 1/2" (13mm) Millboard under fi nish material with minimum "k" factor of 20.07. When unit is raised 4" (102mm), the thermal fl oor protection is not required. If you plan to raise the fi replace and hearth extension, build the platform assembly then position

replace and hearth extension on top. If you are not raising the unit, check that you will have suffi cient clearance under the bottom louver for your finishing material on top of the hearth extension, i.e. tiles, concrete board, etc.

1)Insert the metal safety strip, packaged with the fireplace beneath the fi replace as illustrated in Diagram 1 below. The safety strip should be tacked down to prevent possible shifting and should overlap for continual coverage of the fl oor.

Note: Asafety strip is not required when the fireplace rests on a non-combustible surface.

Note: Install the hearth extension only as illustrated.

The safety strip should extend 2 in. (51 mm) in front and on the sides of the fireplace. In the event a wooden support is used to elevate the fireplace above the fl oor, a “Z” type safety strip should be fabricated from 20 gauge galvanized sheet steel and used to protect the front surface of the wood support as well as the fl oor beneath the hearth extension.

Step (a): Use formula above to convert specifi cation to R-value.

R = 1/k x T = 1/0.84 x .75 = 0.893.

Step (b): Calculate R of proposed system. 4” brick of C = 1.25, therefore Rbrick = 1/C = 1/1.25 = 0.80 1/8” mineral board of k = 0.29, therefore Rmin.bd. = 1/0.29 x 0.125 = 0.431

Total R = Rbrick + Rmineral board = 0.8 + 0.431 = 1.231.

Step (c): Compare proposed system R of 1.231 to specifi ed R of 0.893. Since proposed system R is greater than required, the system is acceptable.
