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. The ducts must be
installed at least 12" (305mm) from the ceiling and
no lower than the cabinet top.
Figures 28 and 29 show construction dimensions for
some of the common duct placements.
Chimney Requirements
For proper draft and best performance, the chimney
should extend at least 15' (4.6m), and not more than 35'
(10.6m), above the hearth surface. If the chimney
above the roof line is enclosed in a chase, the chimney
must extend at least 3' (914mm) 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
rafters 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 ob-
stacle. (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'
(2.5m) 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" (203mm) diameter
chimney systems that have been listed to High Tem-
perature (H.T.) Chimney Standard UL-103-1985
(2100
