This appliance uses a millivolt type control
system consisting of a gas control valve with
regulator (control to adjust for flame appear-
ance and heat output), astanding pilot burner
assembly, a thermopile, thermocouple, a
piezo igniter, and ON/OFF switch. All exhaust
gases must be vented outside the structure.
Combustion air isdrawn from the room where
appliance is installed. THE GAS BURNER
SYSTEM ON THIS APPLIANCE DOES NOT
REQUIRE 120 VOLT POWER TO OPERATE.
However, the heat circulation blower requires
120 Volt power (the appliance can be safely
used with the blower turned off). The blower
operation is controlled by a variable speed
rheostat located on the left side surround
panel (if optional surround is installed)
and temperature switch located beneath of
firebox bottom on the front left side.
Table 1 shows the BTU input:
Test gauge connections are provided on the
front of the millivolt gas control valve (identi-
fied IN for the inlet and OUT for the manifold
side). See Figures 32 & 33.

IMPORTANT NOTE: If propaneisused, be aware
that if the tank size is too small (i.e. under
100-lbs, if this is the only gas appliance in
the dwelling. Ref. NPFA 58), there may be
loss of pressure, resulting in insufficient fuel
delivery (which can result in sooting or other
malfunctions). Any damage resulting from
an improper installation, such as this, is not
covered under the limited warranty.
DETAILED INSTALLATION STEPS
Step 1: PREPARATION - Plan and install gas
line.
This appliance is provided with an opening on
the left hand side of the control compartment.
A 3/8" NPT gas supply pipe must be brought
near this inlet hole.
Gas Supply Line - Installing a gas supply line
from the fuel supply to the appliance involves
numerous considerations of materials, protec-
tion, sizing, locations, controls, pressure, sedi-
ment,and more.Certainlyno oneunfamiliar and
unqualified should attempt sizing or installing
gas piping.
Suggested Sizing of Black Iron Pipe
Schedule 40 - Pipe Supply Line
The proper gas line diameter must be used
to run from the supply regulator (at the gas
company meter) to the appliance. Never use
galvanized or plastic pipe. Refer to table 7
for suggested sizing of the gas supply line if
black iron pipe is being used.
The gas supply line should be connected to
the appliance at step 9 (page 12).
The gas supply line should be plumbed from
the fuel source tothe area where theappliance
is to be installed per requirements outlined
in NFPA 54 - latest edition (USA) or B149
- latest edition (Canada). Step 2: CLEAN FIREPLACE (If necessary)
Thoroughly clean the masonry or factory
built fireplace.
MINIMUM FIREPLACE DIMENSIONS
Refer to Figures 7 & 8 for Minimum Fire-
place Clearance Dimensions. See pages 5
& 6 for actual insert body dimensions.
Consult your local authority having jurisdic-
tion for requirements in your area.
Before the fireplace insert is assembled and
installed, you must consider whether the
appliance must be converted for use with pro-
pane gas (see step 7 on page 9). You must
also consider the vent length requirements.

Purging Air from Appliance
Purge air from appliance by holding gas control valve down in the pilot
position until pilot will light (see Figure 20). DO NOT LIGHT A MATCH IF
YOU SMELL GAS. Light a match then allow gas flow to pilot. If the Match
“blows”, there is air in the line (purge line). If the flame is straight and tall,
there is no gas pressure.
Purging Air from Supply Line
a. Turn gas supply line valve off.
b. Loosen setscrew at inlet pressure tap on control valve (see Figures 32 & 33).
c. Turn gas supply line valve on.
d. When gas flows, turn supply valve off.

Step 9. CONNECTING GAS LINE
GAS CONNECTION
This appliance is equipped with a gas flex line for use (where permit-
ted) in connecting the unit to the gas line. A gas flex line is provided
to aid in attaching the B-Vent appliance to the gas supply. The gas flex
line can only be used where local codes permit. See Figure 19 for flex
line description. The flex line is rated for both natural and propane gas.
A manual shut off valve is also provided with the flex line. The gas con-
trol valve is located in the lower control compartment. To access the
valve, open the lower access door. The millivolt control valve has a 3/8"
(10 mm) NPT thread inlet port fitting.
Make gas line connections. All codes require a shut-off valve mounted in
the supply line. Figure 19 illustrates two methods for connecting the gas
supply. The flex-line method is acceptable in the U.S., however, Canadian
requirements vary depending on locality. Installation must be in compliance
with local codes.

Step 17. SPILLAGE TEST PROCEDURE
(Proper Vent Operation Test):
A flue spillage test should be performed as part
of the installation process to test for proper
vent operation.
Perform the Spill Test as Follows:
1)Lighttheappliance.Adjustfiretohighestflame
setting. Allow unit to operate for approximately
15 minutes. Blower should be off.
2) Close all the external doors and windows.
3)Startall theexhaust fansandother appliances
which remove air from the home (clothes dryer,
furnace, etc.).
4) To ensure a valid test, hold a scrap piece of
sheet metal (or other noncombustible material)
between the spill tube and the top of the door
(to prevent the natural convection of the unit
from interfering with the test).
5) Use an open flame (preferably a wooden
match) or smoke (cigarette, rope) to determine
if spillage is present. Move the flame or smoke
device across the opening of the draft test port
on the front of unit (see Figure 37). If the flame
or smoke is drawn into the opening, there is
no spillage. If the flame or smoke is blown out
or away from the opening, spillage is present
and corrective action should be taken before
operating the appliance.
WARNING: SPILLAGE CAN RESULT IN
CARBON MONOXIDE POISONING WHICH
MAY LEAD TO DEATH!
Combustion and Ventilation Air
WARNING: THIS APPLIANCE NEEDS FRESH
AIR FOR SAFE OPERATION AND MUST
BE INSTALLED WITH PROVISIONS FOR
ADEQUATECOMBUSTIONANDVENTILATION
AIR AVAILABLE TO THE ROOM IN WHICH IT
IS TO BE OPERATED.
Air for combustion is drawn in through the
front of the unit therfore, the front of the unit
must be kept clear of any obstructions.
Follow CAN /CGA B149 (in Canada) or ANSI
Z223.1 (in the USA) requirements, and any
local codes or regulations of the enforcing
authority.
Step 18. CHECK BLOWER SYSTEM
OPERATION
When the insert heats up, the blower will auto-
matically be turned on by the fan disc, located
under the firebox bottom on the front left side.
It will come on at the speed determined by the
rheostat, located on left surround panel (see
Figure 34). To adjust the blower speed, dial the
rheostat to the desired speed setting. Rotate
the dial down (clockwise), just past the click
(the first 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.
WARNING: THE POWER CORD MUST

Note: Spillage occurs when flue gases can
not exit the vent system at an adequate rate
causing it to back up into the dwelling. If
spillage occurs, the heated exhaust spills
out of the draft hood which should result
in tripping the spill switch (see Spill Switch
below) which will shut down the unit. Other
symptoms of flue gas spillage at the draft
hood may include condensation on walls and
windows and/or noticeable odors.
Ifspillage continues, itmaybe aresultof nega-
tive air pressure within the home. To test:
1) Turn off a mechanical devices that were
turned on in step 17, instruction #3 and
retest.
2) Open a window (6" min.) near the insert
and retest.
If spillage continues, The Technician should
contact Technical Services at Lennox Hearth
Products.
Draft Test Port for

Figure 37
SPILL SWITCH - This thermally activated safety
switch will sense the change in temperatrure
and shut down the gas valve in the event of a
severe downdraft or a blocked or disconnected
vent. The switch acts as a safety shut-off to
prevent a build-up of carbon monoxide. If the
flue is blocked or has no "draw," the switch will
automaticlly shut off the supply of gas within
5-10 minutes. Tampering with the switch can
result in Carbon Monoxide (CO) Posioning and
possible death. Carbon monoxide is a color-
less, odorless, highly toxic gas.
If spillage is detected, check the following:
• Check the vent sizing according to
specifications, and vent configurations.
• Examine entire venting system for faults
such as disconnected joints, damaged
vent sections, or sagging liner.
• Make sure vent and air openings are not
obstructed.

Initially, always position the air shutter to the
factory setting as shown in Figure 39 (adjust-
ment rod is located in the lower control area).
This can be done by moving the adjustment
rod up or down accordingly. Allow the burner
to operate for at least 15 minutes. Observe
the flame continuously. If it appears weak
or sooty as previously described, adjust the
air shutter to a more open position until the
proper flame appearance is achieved.
Step 19. BURNER ADJUSTMENT
Flame Appearance and Sooting
When satisfied that the appliance operates
properly, proceed to finish the installation.
Leave the control knob in the ON position and
the on/off switch in the OFF position.
Figure 39
The following chart (Table 10) is provided to
aid you in achieving the correct air shutter
adjustment for your installation.
Air Shutter Adjustment Guidelines:
Burner Adjustment Procedure CAUTION: CARBON WILL BE PRODUCED IF
THE AIR SHUTTER IS CLOSED TOO MUCH.
ANY DAMAGE DUE TO CARBONING RESULT-
ING FROM IMPROPERLY SETTING THE AIR
SHUTTER IS NOT COVERED UNDER THE
WARRANTY.
Appliancesoperatedwith air shutter openings
that are too large will exhibit flames that are
blue and transparent. These weak, blue and
transparent flames are termed anemic. If the
air shutter openings are too small, sooting
may develop.
IMPORTANT: ENSURE THAT THE FRONT
GLASS PANEL IS IN PLACE AND SEALED
DURING ADJUSTMENT.
Sooting is indicated by blackpuffs developing
atthetips of verylong orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior
surfaces adjacent to the vent termination.
Sooting is caused by incomplete combus-
tion in the flames and lack of combustion air
entering the air shutter opening. To achieve
a warm yellow to orange flame that does not
soot, the shutter opening must be adjusted
between these two extremes.
No smoke or soot should be present. Repo-
sition the logs if flames impinge on any of
them. If the logs are properly positioned
and sooting conditions exist, the air shutter
opening on the main burner tube should be
adjusted.
Proper flame appearance is a flame which is
blue at the base and becomes yellow / orange
in the body of the flame. When the insert is
first lit, the entire flame may be blue and will
graduallay turn yellow/orange during the first
6-8 minutes of operation. If after 6-8 minutes
the flame stays lowered blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter may require adjustment.
AIR SHUTTER ADJUSTMENT SHOULD
ONLY BE PERFORMED BY AN AUTHO-
RIZED INSTALLER AT THE TIME OF THE
INSTALLATION OR SERVICE.
CAUTION: THE ADJUSTMENT ROD AND
NEARBY APPLIANCE SURFACES ARE
HOT. EXERCISE CAUTION TO AVOID
INJURY WHILE ADJUSTING FLAME
APPEARANCE.
