Fig. 28 Suggested dimensions and framing for side-venting the air ducts of the chase.
Duct and Vent Placement
The WinterWarm offers great flexibility in positioning the hot air ducts. The ducts can vent through the side of the chase, through its front, or one each through both the side and the front. Either or both ducts also may be vented into a room behind, beside or above the room in which the WinterWarm is installed. Both ducts must be installed in order to properly vent the hot air in- side the energy cabinet. Failure to connect the vent ducts could result in overheating of the cabinet and surrounding construction. The ducts must be installed at least 12” (305 mm) from the ceiling and no lower than the cabinet top.

Chimney Requirements
For proper draft and best performance, the chimney should extend at least 15’ (4.6 m), and not more than 35’ (10.6 m), above the hearth surface. If the chimney above the roof line is enclosed in a chase, the chimney must extend at least 3’ (914 mm) above the top of the chase. The chimney must be supported either from the roof or from the floor joists above the WinterWarm. The cabinet is not intended to be the sole support of the chimney. Support systems are available from the chimney manufacturer.
An installation with a straight, vertical chimney will have the best draft and is the easiest to clean.
If structural components such as floor joists or roof raf- ters are obstacles to the chosen location, however, up to four 30° elbows may be connected directly to each other. Used in pairs, the elbows will return the chimney pipe to vertical after it has passed the obstacle. (In some instances floor joists can be cut and boxed in for reinforcement, but engineered roof trusses should never be cut.) The first offset must be at least 8’ (2.5 m) above the hearth. Elbows may not be used within the chase.
The WinterWarm Fireplace System is listed for use in the United States with seven 8” (203 mm) diameter chimney systems that have been listed to High Temper- ature (H.T.) Chimney Standard
