other problems. A chimney’s flue size should be no less than the existing diameter of a stove’s flue collar and no more
than three (3) times the cross sectional area of the flue size of the catalytic stove’s flue collar. EXAMPLE: Assume the
stove’s flue collar has an inside diameter of 6”. This means the stove’s flue area is approximately 28 square inches, which
means the chimney’s cross sectional flue area cannot exceed 84 square inches. Thus, if the clay tile inside the chimney has
a dimension larger than 8” (200mm) by 8” (200mm) a full liner would need to be installed in the chimney flue to ensure
proper stove draft. The installer should ensure that the proper size chimney tile is installed over the full length of the
chimney. If not, install a properly sized liner to ensure optimal performance.
DRAFT
A good draft is necessary for the proper operation of any stove. Draft is the force created as warm flue gases move up the
chimney and pull fresh air into the stove. Any restriction either at the exhaust or intake ends of the chimney will affect
draft. The amount of draft in the chimney system depends on the length of the chimney, the local geography, nearby
obstructions, prevailing winds, etc. A draft gauge should measure somewhere between 0.05 to 0.07 inches of water
column (W.C.) for the stove to operate efficiently.
MINIMUM CLEARANCES
When installing a catalytic stove into an existing fireplace, ensure that all minimum clearances shown in FIGURE 7 and
defined in TABLE 6 are maintained during installation. Failure to maintain these minimum clearances can create
overheating of the fireplace, the stove, or surrounding combustible materials. Do not seal over the face of any chimney or
air-cooling system of the existing fireplace system. Failure to maintain the proper clearances during installation voids the
Country Flame warranty. Always refer to the Safety Label on the
rear of the specific Country Flame stove being
installed for the latest clearance and installation instructions.

SHROUD AND TRIM INSTALLATION
Each Country Flame insert can be installed with an optional shroud and trim package. There are three shroud and trim
packages available for each catalytic stove depending on the installation requirements. There is the (a) standard shroud kit,
(b) the oversized shroud kit, and (c) the custom shroud kit. The size of the fireplace opening and the surrounding fireplace
facing will determine which one of these kits will be selected by the installer or homeowner. In the event there is any
