The E33I / E33ID may be installed and vented into any solid fuel fireplace that has been installed in
accordance with the National, Provincial/State and local building codes and has been constructed of
noncombustible materials. Before starting, refer to please reference the information in Table 5 and
Figures 27 and 28.
Additionally should extra installation depth be required, the existing fireplace may be re-faced with a
build out in front, constructed completely of non-combustible framing and finishing material (see Figure
26). The build out must be constructed and sealed to prevent any heat from collecting in-between the
existing fireplace and the finishing material. Prior to constructing the build out it is important to know
the overall size of the selected surround panel. For ease of installation and servicing it is recommended
to only have a small overlap from the finished opening. Refer to the minimum fireplace size (table 4)
to compare with the selected surround panel. The flex venting is permitted to have smooth sweeping,
slight angle bends but must not be kinked in any way.
IMPORTANT - Contact your local dealer for further information prior to construction and installation.
