You can also go through a wall at an angle
starting directly at the fireplace as
depicted in Figure 15. An angled wall
insulated radiation shield (RM-12WRSI30
or RM-12RWSI45) must be used wherever
the chimney passes through an exterior
wall.
Please refer to Table 6 for dimensions
pertaining to the installation of the angled
wall insulated radiation shield (RM-
12WRSI30 or RM-12RWSI45). Make sure
to have enough ceiling height for your
installation. If the ceiling height is too low
for the planned installation you may want
to consider installing the fireplace in an
outside chase.
Refer to the angled wall insulated radiation
shield installation sheets for detailed
installation instructions.

NCLOSURE
If the chimney runs up the outside of the
house, we recommend that it be enclosed
in a chase structure. The chase should be
constructed in such a way that it is an
extension of the home (see Figure 15 and
Figure 16). It should be well insulated
between the footings and the floor of the
home to prevent heat loss. If the climate
in your area is mild, insulate the chase at
least to the first firestop. If the climate in
your area is very cold, insulate the chase
to the top to keep the chimney warmer,
increase the draft, and reduce creosote buildup. We also recommend insulating the
ceiling of the chase just as if it were in the attic space. This will prevent cold air from
dropping down through the chase and into the room where the fireplace is installed (see
Figure 15 and Figure 16).
Some local codes require that the walls be insulated, vapor sealed and sheathed with a
fire rated gypsum board (see Figure 15 and Figure 16). We strongly recommend this
procedure for all installations to prevent cold drafts from originating in the fireplace
enclosure. If you follow this procedure, we recommend that you do not insulate the wall
above the front of the fireplace.
REMEMBER: CHECK LOCAL CODES CONCERNING INSTALLATION REQUIREMENTS AND
RESTRICTIONS IN YOUR AREA.
F
RAMING
The enclosure walls can be framed with any suitable materials (2"x4" or 2"x6" studs,
plywood, gypsum board, etc.). Because of the high heat output potential of the
RUMFORD 1500, combustible materials must NOT go closer to the fireplace than the top,
back and sides' standoffs, refer to Figure 3.
