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 5. 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.
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.

MAINTENANCE
(See Maintenance Schedule, Page 28)
Refer to the maintenance schedule for maintenance tasks, procedures, frequency and
by whom they should be performed. Always
verify proper operation of the appliance after
servicing.
WARNING
Turn off gas and electrical power
to the fireplace and allow it to
cool before cleaning or servicing
the appliance.
CAUTION: Wear gloves and safety
glasses for protection while doing
required maintenance.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adéquatement une fois l'entretien terminé.
Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before relighting, refer to the lighting instructions
in this manual. Instructions are also found
on a pull-out panel located in the control
compartment.
Inspect Venting System
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician
(inspection should include ensuring that exhaust
passage is unobstructed and vent components
are properly assembled and not damaged).
Homeowner must contact a qualified service
technician at once if any abnormal condition
is observed.
If the venting system is disassembled for any
reason, a qualified service technician should
follow vent installation instructions for proper
reassembly and proper sealing of the venting
system components. However, more frequent
periodic inspections and cleanings should be
performed by the homeowner.
Cleaning Glass
(see Front Glass Enclosure Panel, Removal and
Installation on Page 12).
Note: Clean glass after first two weeks of operation (after Burn-In period is over) and then only
when necessary and when the fireplace is cool.
Wipe surface with clean, dampened, soft cloth.
Follow with a dry, soft towel as desired. Take
care not to scratch the glass surface.
IMPORTANT: Do not use abrasive cleaners on glass. Never clean the glass when
it is hot.
The viewing glass should be cleaned periodically to remove any build-up caused from the
following:
• During start-up, it is normal for condensation to form on the inside of the glass (this
condensation and fog will usually disappear
in a few minutes). The moisture can cause
lint, dust and other airborne particles to cling
to the glass surface.
• Initial curing of the high temperature paint
and burning off of lubricants used in the
manufacturing process may result in a film
on the glass.
• A white coating may form on the glass as
a result of impurities and minerals in the
fuel.
It is recommended that the glass be cleaned
two or three times during each heating season,
depending on the circumstances present. The
following cleaning solutions are approved for
use to clean glass:
• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar and water
• Gas replace/stove glass cleaner
Inspect Glass Gasket - Visually inspect the
gasket on the backside of the glass enclosure
panels. The gasket surface must be clean, free
of irregularities and seated firmly.
Clean Control Compartment
Keep control compartment clean by vacuuming
or brushing at least twice a year. More frequent
cleaning may be required due to excessive lint
from carpeting, bedding materials, etc. It is
important that control compartments, burners
and circulating air passageways of the appliance
be kept clean.
Clean Logs And Burner
Carefully remove the logs (use care when handling the fiber logs, as they become quite fragile
after curing). Vacuum out any foreign matter
(lint, carbon, etc.) on the burner. Ensure the
burner ports are “open.” Remove any carbon
deposits from the under side of the logs using
a vacuum cleaner, or a soft bristled brush (i.e.
paint brush).
Note: Improper positioning of logs can create
carbon build-up and will alter the performance
of the appliance.
Replacing Logs
If the logs become damaged by accident or
improper handling and need replacement,
use only the proper replacement logs from
manufacturer (see Page 31 for ordering
information).
Re-Install Embers, Logs and Vermiculite
Carefully follow placement instructions on
Pages 12 to 16. All logs should fit onto corresponding pins and/or log stoppers. This will
ensure a proper flame and safe combustion.
Inspect Wiring
Refer to wiring diagrams on Page 19.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify proper operation after
servicing.
ATTENTION: Au moment de l'entretien
des commandes, étiquetez tous les fils
avant de les débrancher. Des erreurs
de cáblage peuvent entraîner un fonctionnement inadéquat et dangereux.
Inspect and clean all wire connections. Ensure
that there is no melting or damage. Inspection
should include:
• Terminals at the Valve
• OFF/ON Switch (optional unit mounted
switch)
• Remote Control or Remote Wall Switch Kit
(optional control switch)
Inspect Burner Flame Appearance
Ensure that the burner flame appearance
resembles the flame shown in Figure 13, 14
or 15 and as described in Flame Appearance
and Sooting on Page 17. The homeowner must
contact a qualified service technician at once if
any abnormal condition is observed.
Small Area Paint Touch-up
Only use a factory supplied paint kit for touchups. Paint is available at your local authorized
Lennox Hearth Products dealer. Never attempt
to paint a hot fireplace.
If the surface later becomes stained or marred,
it may be lightly sanded and touched up with
spray paint.

Burner Flame Appearance - Model MPB-3328
BURNER ADJUSTMENTS
(QUALIFIED TECHNICIANS ONLY)
Flame Appearance and Sooting
Proper flame appearance is a flame which is
blue at the base and becomes yellowish-orange
in the body of the flame. When the appliance
is first lit, the entire flame may be blue and will
gradually turn yellowish-orange during the first
15 minutes of operation. After 15 minutes of
operation, if the flame is blue, or if the flame is
orange with evidence of sooting (black tip), the
air shutter opening may need to be adjusted.
If the air shutter opening is closed too far, sooting
may develop. Sooting is indicated by black puffs
developing at the tips of very long 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 combustion in
the flames and lack of combustion air entering
the air shutter opening. To achieve a warm
yellowish-orange flame with an orange body
that does not soot, the shutter opening must be
adjusted between these two extremes.
Air Shutter Adjustment Guidelines
• If there is smoke or soot present, rst
check the log set positioning to ensure that
the flames are not impinging on any of the
logs. If the log set is properly positioned
and a sooting condition still exists, then the
air shutter opening should be increased.
Figure 14
Figure 15
Burner Flame Appearance - Model MPB-3530
Burner Flame Appearance - Model MPB-4035 & MPB-4540
• If there are offsets in the vent system, the air
shutter opening may need to be increased.
• An appliance operated with the air shutter
opened too far, may have flames that appear
blue and transparent. These weak, blue and
transparent flames are termed anemic.
• Propane models may exhibit ames which
candle or appear stringy. If this is present and
persists, adjust the air shutter to a more open
position, then operate the appliance for a few
more minutes to ensure that the flame normalizes and the flames do not appear sooty.
The following chart is provided to aid you in
achieving the correct air shutter adjustment
for your installation.

D. Plugged burner orifice. Check burner orifice for stoppage and remove.
E. OFF/ON Switch & *Remote Switch are in
the "ON" position resulting in excessive

A. Pilot flame may be too low or blowing (high)
causing the pilot/valve safety to drop out.
Check for spark at electrode and pilot; if no spark and electrode wire is properly connected, replace Igniter.
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 (igniter rod) and pilot – should be 1/8" to have
a strong spark. If gap measures 1/8", replace pilot (see
Figure 17 on Page 18).

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.
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.
When turning on the burner using a *remote switch, ensure
that the unit mounted (optional) OFF/ON switch is in the
"OFF" position. If both switches are in the ON position, it
may result in excessive resistance (& millivolt drainage)
and the burner may not come on.
Clean and/or adjust pilot flame for maximum flame impingement on thermocouple (see Figure 17 on Page 18).
