VENTING INSTALLATION
Continued
Instructions for chase installations are
included with the chase style termination
chosen. In a multiple chase installation, be
sure to provide adequate distance between
terminations to prevent smoke spillage from
one termination to another. Terminations must
be separated a minimum of 30" center to cen-
ter and stacked at a minimum vertical height
difference of 18" (see Figure 26).
Note: If a decorative shroud is to be installed,
contact the manufacturer for specications.
FINISHING FIREBOX
Any noncombustible material may be used
for facing (glass, tile, brick, etc.) as long as
proper clearances are adhered to and rebox
openings are not obstructed in any way (see
Figure 27).
Use only heat resistant, noncombustible mor-
tar or adhesive when securing facing material
to front of rebox. When placing facing at
upper edge of effective opening of rebox,
provide “L” shaped piece of metal extending
full width of opening (see Figure 27).
Secure with sheet metal screws at a distance
high enough from edge so it doesn't interfere
with operation of doors. This assures that fac-
ing material will not block openings.
