HOT AIR DUCT INSTALLATION
The hot air outlets may be vented into the same room as the
fireplace or to an adjacent room or second floor. When going
through a combustible wall or floor, a radiation shield must
be installed in the wall. The required hole size is 13" x 13"
for studs and flooring.
CAUTIONS:
1. Do not install heat registers below the level of the two
hot air outlets on the top of the fireplace.
2. Do not tie the ducts into a central heating system.
3. All hot air ductwork must be 8" diameter B-Vent
through the initial wall or ceiling penetration. Single
wall pipe may then be used providing booster fans and
backdraft dampers are installed on upward ducting.
4. Use only outlet registers approved for this unit.
Other registers may restrict air flow causing
overheating.
5. Do not run hot air ducts for a distance greater
than 10' unless system is equipped with booster
fans. (See page 6.)
6. Maintain a 2" minimum clearance from ducts to
combustibles.
NOTE:
The grills must exit at least 18" away from
the ceiling and 16" from the side walls.
2" from sidewall if duct booster fans are installed
with snap disks.
