The Model BBF catalytic stove is the largest and heaviest catalytic combustor stove that Country Flame produces. This
stove can handle 29-inch cut wood. The stove’s firebox is made from
5/16-inch thick steel. Some of the stove’s
combustion components are made from ½-inch thick steel. This stove weighs close to 600 pounds. The Model BBF’s
mass is one of its advantages (except to the installer) because as the stove reaches operating temperatures, its thermal
mass maintains a uniform burn rate. In addition, the large stove door allows for full viewing of a beautiful wood fire. All
of these features give the Model BBF catalytic stove a heating capability that will warm an entire house. Truly, the Model
BBF is a top of the line catalytic heating machine.
A Model BBF can be installed as a freestanding or the Model BBF can be inserted into an existing masonry fireplace. Do
not remove any bricks or mortar from a masonry fireplace to accommodate a BBF insert. Whichever way the homeowner
chooses to purchase and install the BBF, it comes standard with a blower system capable of moving room air at 600 cubic
feet per minute. This blower system is housed in a convenient blower tray that slides into the lower front of the Model
BBF. The blower system is used to warm and circulate room air. NOTE: The Model BBF catalytic stove is not approved
for installation into a zero clearance fireplace. Refer to the MODEL BBF (Freestanding/Insert) section for the Model
BBF stove specifications. Please contact Country Flame or one of its local authorized dealers to resolve any installation
issue, request further assistance, or obtain the latest recommended procedures.
Freestanding BBF catalytic stove applications should follow FIGURE 1 and TABLE 1 in order for the installer to
conform to minimum clearance requirements. The Model BBF freestanding stove requires a minimum of: a) a 21-inch
clearance from sidewalls, b) a 20-inch clearance from back walls, and c) a 20-inch clearance from any adjacent walls with
a 45-degree angle to the adjacent walls. The installer should consult national and locale codes for additional information.
Always refer to the Safety Label on the
rear of the stove for the latest clearance and installation instructions before
installing the Model BBF.
Freestanding floor protection requirements are shown in FIGURE 4 and TABLE 3. A listed floor protector must have a
minimum total “R” value of 2.0. Floor protection must extend a) a minimum of 8 inches from the stove opening to each
side of the unit and b) a minimum of 18 inches from the face of the BBF stove.
Insert a BBF catalytic stove into an existing masonry fireplace and maintain proper minimum clearances. Refer to
FIGURE 7 and TABLE 6 for minimum clearance requirements. The BBF stove requires minimum clearances of: a) 2
inches from side and back walls in the zero clearance fireplace, b) 26 inches from the top of the BBF to the bottom of a
combustible mantel, c) 10 inches from the BBF firebox opening to any combustible wall face material, d) and 21 inches
from the BBF firebox opening to any combustible sidewalls. The use of a listed floor protector requires a minimum of a)
8 inches from each side of the BBF firebox opening and b) 18 inches of depth from the face of the BBF stove. Failure to
maintain clearances can create overheating of combustible materials and lead to a house fire. Failure to maintain the
proper clearances will void the Country Flame warranty. A hearth extension that was part of the previous masonry
fireplace installation must be used in the BBF insert installation; however, minimum clearances to combustibles are still
required. Use a listed floor protector with a minimum thermal conductivity of K = 0.85 Btu – inches per square foot per
hour per degree Fahrenheit and equivalent to 3/8” (9.4mm) non-asbestos millboard.
