Placement in Fireplace with a Restrictive Barrier
The following are guidelines for placing a gas log set in a
fireplace that has a restrictive barrier on the fireplace for
vented appliance only. See Figure 2.3.
Height of Restriction
(x)
No Restriction
0" to 3" (76mm)
Greater than 3" (76mm)
*Any barrier greater than 3" placed in front of the gas log set is not
recommended by the manufacturer.
NOTE: Non-combustible material such as refractory brick
may be used to line the floor of the fireplace in order to raise
the height of the gas log set in relation to a restrictive barrier.
If the unit is raised, the minimum height dimension listed
in the homeowner's manual must be met or exceeded.
NOTE: If the log set is equipped with a remote receiver, a
restrictive barrier may reduce the battery life by increasing
the ambient temperature inside the fireplace. Placement of
the receiver outside of the fireplace will extend the battery
life. (MV models only)
WARNING
Barriers such as the bottom of a glass door frame
placed in front of a gas log set can change the air
flow characteristics of the fireplace which in turn
can cause the unit to overheat and malfunction when
installed as a vented log set.

in an Enclosure
Do not install the heater:
•
Where curtains, furniture, clothing, or
other flammable objects are less than
36" from the front of the heater.
•
In high traffic areas.
•
In windy or drafty areas.
Gloves are recommended when handling
logs to prevent skin irritation from loose
fibers. Logs are fragile—handle with care.
If the area in which the heater may be
operated does not meet the required volume
for indoor combustion air, combustion and
ventilation air shall be provided by one
of the methods described in the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code or applicable
local codes.
The log set should be placed against
or as near as possible to the rear
wall of the fireplace/firebox.
