Hearth & Home Technologies • SMART-WALL-B Air Duct Kit • 4086-348 Rev. D • 3/20
The purpose of this kit is to keep the area above the appli-
ance at a temperature that is within the at screen style TV
manufacturer’s specied maximum operating temperature.
The ability of the SMART-WALL-B TV Kit to accomplish
this purpose is expressly dependent upon the following
conditions.
• The manufacturer’s specied maximum operating tem-
perature (for the TV unit being used in this application)
being no less than 100 degrees Fahrenheit (consult
your manufacturer to determine the maximum operating
temperature for your TV unit);
If the specied maximum operating temperature
for your TV unit is less than 100 degrees Fahren-
heit, do not use that particular TV in this application.
• The back of the TV unit (after installation on a wall
mounted bracket) having and maintaining not less than
a 3-inch gap between the back of the TV unit and the
wall. This is the gap between the back of the TV and
the wall which is vital for proper air and temperature
circulation.
• The ambient temperature of the room is maintained at
75 degrees Fahrenheit or less.
• The SMART-WALL-B TV Kit and the TV must be installed
and operated in strict compliance with all other appli-
cable installation and operation instructions for this kit.

Preliminary Preparation
Contents of kit:
Please note, while the SMART-WALL-B TV Kit, when in-
stalled and used properly will allow most TVs to operate
above the replace appliance without damaging the TV,
operating a TV at the higher end of the manufacturer’s
maximum operating temperature range, may and likely
will have some impact on the life span of the TV appliance
compared to operating it at normal ambient temperatures.
The SMART-WALL-B uses a control module that must
be used with the IntelliFire™ Touch control system. The
SMART-WALL-B blower turns on and operates for two
minutes before the ignition sequence begins. The SMART-
WALL-B blower remains on for 20 minutes after the appli-
ance is turned o󰀨 to remove residual heat so the TV does
not overheat.
NOTICE: DO NOT install a GFK-160A fan kit in a
replace equipped with the SMART-WALL-B TV kit. The
GFK-160A fan could cause the TV to overheat.
Approvals
The exible duct in this Smart-Wall™ (SMART-WALL-B)
TV kit is manufactured and marked to the requirements of
UL-181, Class I air duct.
Introduction
The SMART-WALL-B TV kit conveys warm air from the
appliance through an air duct to remote locations in the
same room or other rooms of the building. See Figure 1.
This kit is only approved for use with the following models:
Hearth & Home Technologies does not guarantee that a
user’s TV will safely operate long-term in conditions not
strictly in compliance with those described in the previous
paragraph.
