To light the burner, rotate the gas valve control
knob counterclockwise to the “ON” position
then turn “ON” the off/on switch mounted
on the surround assembly (see Figures 1 &
2 on Page 3) or operate the burner with the
optional remote control, wall thermostat or
control switch.
With proper care and maintenance, your appli-
ance will provide many years of enjoyment. If
you should experience any problem, fi rst refer
to the troubleshooting guide in this manual. If
problem persists, contact your Lennox Hearth
Products Dealer.
BLOWER OPERATION
When the insert heats up, the blower will auto-
matically be turned on by the fan disc located
under the fi rebox bottom on the front left side.
It will come on at the speed determined by the
rheostat located on the side surround panel (see
Figure 4 on Page 4). To adjust the blower speed,
dial the rheostat to the desired speed setting.
Rotate the dial down (clockwise), just past the
click (the fi rst ON position) for the highest speed
setting. Turning the knob further clockwise will
provide slower blower speeds.
Note: If the rheostat is not turned “on,” the
blower will not operate.
Proper Pilot Flame Appearance
MILLIVOLT APPLIANCE CHECKOUT
Light the pilot by following the instructions on
Page 15 or 16 of this manual.
The pilot fl ame should be steady, not lifting
or fl oating. Flame should be blue in color with
traces of orange at the outer edge. The top 3/8"
(10 mm) at the pilot generator (thermopile)
and the top 1/8" minimum (tip) of the quick
drop out thermocouple should be engulfed
in the pilot fl ame. The fl ame should project 1"
(25 mm) beyond the hood at all three ports
(Figure 25).
Replace logs if removed for pilot inspec-
tion.

FIREPLACE REQUIREMENTS
IMPORTANT: When installing this appliance
into a factory built fi replace or heatform, the air
fl ow within and around the fi replace shall not
be altered by the installation of the insert (i.e.
DO NOT BLOCK louvers or cooling air inlet or
outlet ports, circulating air chambers in a steel
fi replace liner or metal heat circulator).
CAUTION: The factory built fi rebox must
accept the insert without modifi cation other
than removing bolted or screwed together
pieces such as smoke shelf/defl ectors, ash lips,
screen or door tracks, log grates, refractory and
damper assemblies. Any fi replace component,
which is removed, must be retained so they
can be reinstalled to restore the fi replace to
its original operating condition. The removal
of any part must not alter the integrity of the
outer shell of the pre-engineered fi replace
cabinet in any way.
If any components are removed from (or altered)
from the existing fi replace, a Warning Label
(see below) must be affi xed inside the fi replace
fi rebox, so that it shall be visible upon removal of
the fi replace insert. Note: RTV high temperature
silicone is an approved adhesive.
