SB50HB Series Woodburning Fireplace
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 as shown by
Figure
8
. 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 use. Poor installation or location of the
chimney cap and/or components can cause wind blown
rain to enter the chimney.

NOTeS:
1. Firestop spacer must be used.
. Local codes may not require firestop-
ping at the ceiling level for chase in-
stallation, but it is recommended for
safety and reducing heat loss.
3. Do not insulate the chase with blown
or fill type insulation. Insulation
should only contact the fireplace at
points where the fireplace would nor-
mally be contacted by framing mate-
rials.
Be sure the selected location will allow a 17” square
combustible material-free space for the chimney to pass
through. If the chimney is to pass through living or storage
spaces, be sure there is adequate space to enclose the
chimney to avoid personal contact with, or damage to, the
chimney. If the fireplace is to be installed on an outside
wall, the surrounding walls (chase) should be constructed
and insulated as shown by
Figure 5
. Failure to insulate the
fireplace from outside temperatures will cause heat loss
through and around the fireplace.
