624WBPF Woodburning Fireplace
53D9052
Survey the planned location for the fireplace for overhead plumbing or electrical wires, etc., that
might complicate the installation or endanger persons installing or cleaning the chimney. Avoid
a location where the chimney cap will be near abrupt changes in the roof shape, nearby wall or
embankments, under or near trees or above the roof of a single story wing of a two story building.
Figure 6. All these conditions can cause turbulence or pressure conditions that can cause poor
chimney draft and smoke spillage from the fireplace opening. Elbows may be used to offset the
chimney to avoid obstructions or to locate the chimney cap in a preferred location. Refer to the
sections of this manual pertaining to chimney offsets for instructions on proper elbow usage. Poor
installation or location of the chimney cap and/or components can cause wind blown rain to enter
the chimney.
If the fireplace is to be installed on an outside wall, the surrounding walls (chase) should be insu-
lated. Failure to insulate the fireplace from outside temperatures will cause heat loss through and
around the fireplace.
