Heat Releases; Air Intake - Honeywell Flare Front Series Installation Manual

HEAT RELEASES

All Flare Fireplaces (both safety screen and double glass units) require heat releases for warm air to flow back into the room.
This controls the temperature of the surrounding walls, keeping them relatively cool. These relatively quiet blowers cannot be
turned off and are required for the continued operation of your Double Glass system.
Top Hot Release - The release/ outlet for hot airflow from the wall enclosure MUST remain OPEN. The outlet must be at the top
part of the enclosure but not necessarily at the front, so long as the measurements below are maintained. Heat release opening
can be installed at the sides of the enclosure (one on every side), back or on top of (in case of a drop wall design).
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.
The top of the outlet(s) must be at least 1" (25mm) down from the ceiling firestop, and no more than 3" (76mm) down. The
vent can also be installed on top of the enclosure, as a drop wall (a chase that is not built all the way to the upper ceiling). Any
opening greater than the minimum size is highly recommended and will help reduce the temperature of the surrounding
walls. Make sure a non-combustible fire stop is placed atop the inside of the chase and is framed in a way that does not
allow any pockets of heat to be formed.

AIR INTAKE

Required for installation with double glass or safety screen with optional blower kit. This allows air circulation which cools the
external glass and increases the efficiency of the fireplace. See diagram on page 63.
Lower Air Intake - Optional for normal safety screen installation. Required for installation with double glass or safety screen
with optional blower kit.
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 FIREPLACES THE AIR INTAKE REQUIREMENTS ARE DOUBLE, EQUAL ON BOTH SIDES.
NOTE: Openings above for Heat Release and Air Intake are measured for open air space. The fans for the Double Glass cannot
Lower vent opening can also be used as an access door to the gas valve if it meets both requirements in terms of size. Lower
vent opening can be installed at the sides of the enclosure (one on every side), back or front. It is recommended to place one
opening on either side of longer units, to allow for better distribution across all fans of air taken in from the bottom.
