NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Outside Combustion Air Controls
Many appliances are equipped, when installed,
with an outside (make-up air) vent system that
is designed to provide the appliance with outside
make-up air for combustion when in operation.
The combustion air control lever for the outside
air system is standard on all appliances but
should not be operated if the complete system
is not installed. Refer to Figure 4. When the
complete outside air vent system is installed,
the installer will remove the securing screw from
the combustion air control lever located on the
left side of the fireplace bottom opening.
If the securing screw has not been removed
and you have reason to believe that you have
a complete outside air system, contact your
distributor to have your appliance inspected for
the presence of the complete system. DO NOT
assume that you have this system in place.
WARNING
Do not operate the shutoff lever
unless a complete outside combustion air system has been installed
with your appliance.
To open the outside air shutter, open the bottom
control access panel, reach into control compartment and pull the combustion air control
lever all the way out. The outside air shutter
should be fully open when the fireplace is in
use and completely closed when the fireplace
is not being used. Closing it when not in use
will prevent outside cold air from entering the
dwelling.
Step 13. Spillage Test and Safety Limit
Switch Operation
Manually-Reset Safety Limit Switch
This appliance is equipped with a manually-reset
blocked flue safety limit switch. Refer to Figure
5 on Page 7 for its location. If, during appliance
operation, the flame goes out (independently of

With proper care and maintenance, your appliance will provide many years of enjoyment. If
you should experience any problem, first refer
to the trouble shooting guide in this manual.
If problem persists, contact your Lennox
distributor.
Log Placement
WARNING
Logs get very hot and will remain
hot up to one hour after gas supply
is turned off. Handle only when
logs are cool. Turn off all electricity
to the appliance before you install
grate and logs.
WARNING
This appliance is not meant to burn
wood. Any attempt to do so could
cause irreparable damage to your
appliance and prove hazardous to
your safety.

WARNING
The size and position on the log set
IS Critical to give your appliance a
safe, reliable and attractive flame
pattern. Any attempt to use a different log set in the fireplace will
void the Warranty and will result in
incomplete combustion, sooting,
and poor flame quality.
Initial Installation Considerations
The packaged logs are located within the firebox.
The decorative volcanic stone and glowing
embers are packaged separately in plastic bags
located in the control area of the fireplace.
If the logs are being installed for the first time,
the following paragraphs apply:
DO NOT attempt to install the logs until the appliance installation has been completed, the gas
line connected and tested for leaks and the initial
burner operation has been checked out.
Proper twig placement is critical to prevent sooting. Twigs should be placed in the gaps between
the flame peaks and should be positioned so
that at no time they impinge the flames.
Step 1. Remove the appliance front door.
Step 2. Remove the log set from the interior
of the fireplace.
Step 3. Remove the logs from their packaging.
Handle logs carefully to prevent breakage.
Step 4. MPB-4035 & MPB-4540 Models
- Remove the restraining strap from the grate
tines. Ensure the grate is fully inserted into
the holes on the firebox rear panel and over
the indents on the firebox floor.

Glowing Embers, Vermiculite, Decorative Volcanic Stone And Log
Placement Instructions:
Glowing Embers
Step 1. Separate the Glowing Embers (Rockwool) into pieces about
the size of a quarter (see Figure 13). Keep the pieces fluffed up, not
matted.
MPB-3328 & MPB-3530 Models Distribute these pieces over the burner as shown in Figure 14. Do not use
more than is shown. The glowing embers should not be placed directly
over the large burner slots as shown in Figure 14.
MPB-4035 & MPB-4540 Models Place the center log (Log No. 1) on the burner as shown on Page 12.
Distribute the glowing ember pieces at the front of the burner as shown
in Figure 15. Do not use more than is shown. The glowing embers
should not be placed directly over the large burner slots as shown in
Figure 15.

Note: This appliance is provided with enough Glowing Embers for
several applications; do not feel compelled to use all that is in a
new bag. For best glowing effect, replace the ember material annually. Replacement Glowing Embers are available (Catalogue Number
88L53).
Step 2. Mound up a portion of the vermiculite (light colored material) in
front of the burner and grate. Sprinkle the dark colored decorative volcanic
stone on top of the vermiculite in a pleasing pattern. For best results,
spread in a non-uniform manner while ensuring complete coverage of
the black sheetmetal surface.
See Figure 14 - MPB-3328 or MPB-3530, or Figure 15 - MPB-4035 or
MPB-4540 models.
Note: Do Not place vermiculite or decorative volcanic stone on top of
the gas burner where it will block the burner ports.
Step 3. Position the individual logs as described on Pages 11 (MPB3328), 12 (MPB-3530) or 13 (MPB-4035 and MPB-4540).
Do Not Place Glowing Embers Over Large Burner Ports

TROUBLESHOOTING
Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, iff applicable), is
in the “ON” position. Important: Valve system troubleshooting should only be accomplished by a qualified service technician.
TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM
SYMPTOM
POSSIBLE CAUSES
CORRECTIVE ACTION
A. Defective igniter
(no spark at electrode).
Check for spark at electrode and pilot; if no spark
and electrode wire is properly connected, replace
Igniter.
B. Defective or misaligned electrode at pilot
(spark at electrode).
Using a match, light pilot. If pilot lights, turn off pilot
and trigger the igniter button again. If pilot lights, an
improper gas mixture caused the bad lighting and
a longer purge period is recommended. If pilot will
not light – check gap at electrode and pilot – should
be 1/8" to have a strong spark. If gap measures 1/8",
replace pilot (see Figure 8 on Page 8).
C. Gas supply pressure errant.
Check inlet gas pressure. It should be within the limits
as marked on the rating plate.
D. Pilot orifice plugged.
Clean or replace pilot orifice.
2. Pilot will not stay lit after
carefully following the lighting
instructions.
A. Defective pilot generator
(thermocouple).
Check pilot flame, it must impinge on thermocouple
(see Figure 8 on Page 8). Clean and/or adjust pilot
for maximum flame impingement on thermocouple.
Ensure that the connection between the valve and
thermocouple are tight and secure.
3. Pilot burning, no gas to burner, Valve
knob “ON,” Wall Switch “ON.”
A. Limit Switch defective.
Isolate the “limit” switch. Disconnect the wires from
the “ON/OFF” switch and the valve (label wires for
reattachment). Test for continuity with a multimeter.
If continuity is not indicated, switch is defective and
must be replaced.
B. Wall switch or wires defective.
Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch. If okay, jumper
wires across wall switch wires at valve, if burner comes
on, wires are faulty or connections are bad.
C. Thermopile may not be generating sufficient millivoltage.
Check thermopile with millivolt meter. Take reading
at thermopile terminals of gas valve. Should read
325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below
specified minimum.
D. Plugged burner orifice.
Check burner orifice for stoppage and remove.
A. Pilot flame may be too low or blowing (high)
causing the pilot/valve safety to drop out.
Clean and/or adjust pilot flame for maximum flame
impingement on thermocouple (see Figures 8 on
Page 8).
1. Spark Igniter will not light pilot after
repeated triggering of Igniter button.
4. Frequent pilot/burner outage problem.
TROUBLESHOOTING GUIDE - ELECTRONIC IGNITION SYSTEM
SYMPTOM
1. Burner will not light.
POSSIBLE CAUSES
CORRECTIVE ACTION
A. Faulty Valve System.
See Below.
B. “OFF/ON” or wall switch defective.
Disconnect the two black wires from the wire nuts.
Test switch(s) for continuity with a multimeter. If
continuity is not indicated, switch(s) is defective and
must be replaced.
Note: Before replacing “OFF/ON” switch, Ensure to
check wiring for loose connections or broken wires
and repair as needed.
2. Burners come “ON,” then turns “OFF.”
A. Burner orifice plugged.
Check main burner orifice(s) for blockage. Clean
or replace.
B. Obstructed vent system.
Check vent system for obstructions.
