Operating instructions

Installation
4. Using the template make the block-
off plate of 24 gauge or thicker steel.
Drill two (2) holes in each ange for
mounting the plate.
5. Mount the block-off plate using
masonry screws in a masonry
replace and sheet metal screws on a
zero-clearance replace (screws need
only be long enough to penetrate the
rst layer of metal).
6. Insulate the block-off plate using high
- temperature berglass insulation
and furnace cement.
7. After installing the unit into place and
the pipe through the block-off plate,
use high - temperature berglass
insulation and furnace cement to seal
any gaps between the pipe and block-
off plate (allow the cement to dry for
at least 24 hours before burning).

Zero Clearance Notes:
The replace must not be altered, except for the exceptions below. The
permanent metal warning label provided must be attached to the back of the
replace, stating that the replace may have been altered to accommodate
the insert, and must be returned to original condition for use as a conventional
replace. The following modication of factory built
replaces are permissible: removal of damper, removal
of smoke shelf or bafe, removal of ember catches,
removal of re grate, removal of viewing screen/curtain,
and removal of doors. The factory built chimney must be
listed per UL 127 (US), and meet type HT requirements
of UL 103 (US). Factory built replace chimneys tested
to UL 127-1998, may be at the replace manufacturer’s
option, tested to the same criteria as UL 103 HT
requirements. If the chimney is not listed as meeting HT
requirements, or if the factory built replace was tested
prior to 1998, a full height listed chimney liner must be
installed from the appliance ue collar to the chimney top.
The liner must meet type HT requirements (2100°F) per
UL 1777 (US). The liner must be securely attached to the
insert ue collar and the chimney top. To prevent room
air passage to the chimney cavity of the replace, seal
either the damper area around the chimney liner with high
temperature sealant or the replace front with berglass
batting.
