A
. Top Vent system - Hot Airflow outlet from the wall enclosure
MUST
remain open. For Flare See Through fireplace, open
vent must exist in both sides of the glass. The outlet must be at the top part of the enclosure but not necessarily at the front
if the measurements below are maintained.
For fireplaces sized
80” & 100”
–
vent area must be at least
200 square inches OPEN AIR FLOW.
For fireplaces sized
60” & 70”
- vent area must be at least
140 square inches OPEN AIR FLOW
.
For fireplace sized
50”
and below - vent area must be at least
100 square inches OPEN AIR FLOW
B
. Open air flow for hot air to rise from the fireplace to the top of the enclosure. The enclosure can be supported by studs,
but open-air flow
MUST
be maintained at all time. In case needed, insulation for electric wires or systems may be added but
it is
important
to keep most of the air flow open.
Never place any insulation on the fireplace
.
C
. Metal Stud below non-combustible material line. Below non-combustible line, all studs used should be metal type. No
studs to be connected to the fireplace frame (1/2 Inch clearance). Open hot airflow
MUST
be maintained and should not be
blocked.
Note: Max recess of TV cavity should not exceed 6”. Recesses exceeding this dimension run the risk
of creating a
shelf and hindering air flow above unit, resulting in a wall that may overheat.
D
. Non-combustible material is placed flat on the front fireplace support bracket. The support bracket holds the fire-rated,
non-combustible, material and allows hot air to rise from the glass into the fireplace enclosure. Hot air is to be released into
the room using the top static vent opening.
The fireplace enclosure must allow air to rise and circulate from the top of the fireplace glass (from lower vent opening), to
be released back to the room from the top. To increase heating, the enclosure should prevent hot air from being released to
the attic by venting it back to the room using the static vent system (A).
Non-combustible stud
MUST NOT
be connected or drilled into the fireplace frame. Drilling into the fireplace frame can result
in damage to the fireplace.
E
. Cold air, drafted from the room through the lower static vent, (G) flows up and is heated by the fireplace. The Cold air gap
should remain open to allow air to flow up and exchange heat with the fireplace. The fireplace can be installed with double
glazing glass system or safety screens. Blower system may be used to push cold air up (F).
F
. Heat exchange blowers are optional when fireplace is installed with safety screens. Heat exchange blowers must be
included when installing a double-glazing fireplace. The blowers are designed to move cold air from the room using the
lower vent opening (G) up against the fireplace glass. As the air flows on the glass, it is heated and released back to the room
from the glass front and from the top (A) vent opening.
G
. Lower vent opening.
Optional
for normal installation. A
Must
for double glass installation or blower kit option.
For fireplaces sized
80” & 100”
–
vent area must be at least
100 square inches OPEN AIR FLOW.
For fireplaces sized
60” & 70”
- vent area must be at least
70 square inches OPEN AIR FLOW
.
For fireplaces sized
50”
and below - vent area must be at least
50 square inches OPEN AIR FLOW.
For See Through and Room Definer fireplaces, the air intake requirements are
double
.
H
. Adjustable fireplace legs.
