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 of the fireplace for
vented appliance only. See Figure 2.2.
Height of Restriction
(x)
No Restriction
0" to 3"
Greater than 3"
Table 1
*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.
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.
WARNING
DO NOT INSTALL ANY GLASS OR BARRIERS ON
A VENTLESS FIREBOX UNLESS APPROVED BY
MANUFACTURER
Fireplaces with adjustable louvers
should have the louvers fully open
while the unit is in operation.
Height of restrictive barrier caused
by glass door frames, recessed
fireplaces, etc. from the base or
bottom surface of the unit. (Refer to
Table 1).

F. Pilot/ODS
The gas log heater is fitted with a specially designed safety
pilot (ODS assembly) which senses the amount of oxygen
available in the room and shuts the gas log heater off if the
oxygen level begins to drop below a satisfactory level. The
pilot can only be relit when adequate fresh air is available.
WARNING
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.
WARNING
Gloves are recommended when handling
logs to prevent skin irritation from loose
materials.
Logs are fragile—handle with
care.
The log set should be placed
against or as near as possible to
the rear wall of the fireplace/firebox.
Doors on a wood burning
fireplace or vent free firebox
must be fully open during
operation unless specified and
approved by manufacturer.
