The Model B catalytic stove is the second largest catalytic combustor stove that Country Flame produces. This stove can
accommodate a large 24-inch (610mm) cut wood log. This stove has a large firebox whose volume is 3.4 cubic feet. The
firebox is made from 5/16-inch thick steel. Some of the firebox combustion parts are made from ½-inch thick steel. This
stove weighs in around 560 pounds. The B’s mass is one of its advantages (except to the installer) because as the stove
reaches operating temperatures, its large thermal mass maintains a uniform burn rate. In addition to the features mention,
the Model B also has a large front glass to allow for full viewing of the beautiful wood fire. The Model B catalytic stove
has the heating capacity to warm an entire house. Truly, the Model B is an excellent catalytic heating machine.
The Model B can be installed as a freestanding model or the Model B can be inserted into an existing masonry fireplace.
Do not remove any bricks or mortar from a masonry fireplace to accommodate a Model B insert. Whichever way the
homeowner chooses to purchase and install the Model B, 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
housing of the Model B. The blower system is used to warm and circulate room air. NOTE: The Model B catalytic stove
is not approved for installation into a zero clearance fireplace. Refer to the MODEL B (Freestanding/Insert) section for
the Model B 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 Model B catalytic stove applications should follow FIGURE 1 and TABLE 1 in order for the installer to
conform to the minimum clearance requirements. The Model B freestanding stove requires a minimum of: a) an 18-inch
clearance from sidewalls, b) a 29-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 B.
Freestanding floor protection requirements are shown on FIGURE 4 and TABLE 3 for all models. 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 Model B stove.
Insert a Model B catalytic stove into an existing masonry fireplace and maintain proper minimum clearances. Refer to
FIGURE 7 and TABLE 6 for minimum clearance requirements. The Model B stove requires minimum clearances of: a) 2
inches from side and back walls in the zero clearance fireplace, b) 16 inches from the top of the Model B to the bottom of
a combustible mantel, c) 8 inches from the Model B firebox opening to any combustible wall face material, d) and 18
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.
Refer to APPENDIX G for information on venting and chimney requirements.
