These millivolt appliances are designed to
operate on either natural or propane gas. A
millivolt gas control valve with piezo ignition
system provides safe, efficient operation.
External electrical power is required to operate
the air circulation blower.
These appliances comply with National
Safety Standards and are tested and listed
by OMNI-Test Laboratories Inc.; Beaverton,
Oregon (see report numbers on cover) to
ANSI Z21.88 (in Canada, CSA-2.33), and
CAN/CGA-2.17-M91 in both USA and Canada,
as vented gas heaters.
Installation must conform to local codes.
In the absence of local codes, installation
must comply with the current National Fuel
Gas Code, ANSI Z223.1 / NFPA 54 - latest
edition. (In Canada, the current CAN-1 B149
installation code.) Electrical wiring must
comply with the National Electrical Code
ANSI/ NFPA 70 - latest edition. In Canada,
the current CSA C22-1 Canadian Electrical
Code - latest edition.
GENERAL INFORMATION
Installation, repair and annual service inspection should be performed by a qualified
service technician.
It is imperative that the control compart-
ment, burners and circulating air passage
ways of the appliance be kept clean.
S'assurer que le brùleur et le compartiment

GAS CONTROLS
-
See Figure 3, showing how to access the
control compartment.
CONTROL COMPARTMENT ACCESS
Pull down hinged door to access control
compartment
(see Figure 3).
This appliance must be isolated from the
gas supply piping system (by closing its
individual manual shut-off valve) during
any pressure testing of the gas supply
piping system at test pressures
equal to
or less than 1/2 psig (3.5 kPa).
This appliance and its individual shut-off
valve
must be disconnected from the gas
supply piping system during any pressure
testing of that system at pressures
greater
than 1/2 psig (3.5 kPa).
This appliance must not be connected to a
chimney or flue serving a separate solid-fuel
appliance.
Burn-in Period
During the first few burns of these appliances
there will be some odor due to the curing of the
high temperature paint and burning off of lubri
cants used in the manufacturing process.
Depending on your use, the burn-in period may
take a few hours or a few days.
Do not turn on
blower during Burn-In period.
IMPORTANT
Keep your house well ventilated
during the curing process. The
odor and haze emitted by the
curing process can be quite
noticeable and may set off a
smoke detector.
These millivolt appliances are fitted with a burner
ON/OFF Switch, located on the side surround
panel as shown in
Figure 4 on Page 4. Once
the pilot is lit, and valve knob is in the ON posi
tion, the ON/OFF switch will control the appliance
ON/OFF operation. To operate, toggle the switch
between its ON and OFF positions.
Variable Flame Height Adjustment
These millivolt appliances are equipped with a
variable gas control valve. Flame height may be
adjusted through a range between fixed low and
high settings by rotating the HI/LO knob on the
valve (see Figures 1 & 2) alternately, while the
appliances are in operation.

OPERATION AND CARE OF YOUR
APPLIANCE
WARNING
IMPORTANT
Appliance operation may be controlled through
a remotely located optional wall thermostat or
remote control.
In lieu of remote control or remote wall thermo
stat operation, the appliance must be operated
directly through the on/off switch located on the
surround panel (see
If your millivolt appliance is equipped with an
optional wall thermostat kit or remote control
kit and the pilot is lit (and valve is in the On
position), the appliance main burner may be
turned on and off with the wall thermostat or
remote control.
Always keep the appliance area clear and free
from combustible materials, gasoline and other
flammable liquids.
Remember, Millivolt appliances have a continu
ous burning pilot flame. Exercise caution when
using products with combustible vapors.
Figure 4).
MAINTENANCE
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician.
However, more frequent periodic inspections
and cleanings should be performed by the
homeowner. Homeowner must contact a quali
fied service technician at once if any abnormal
condition is observed.
Refer to the maintenance schedule on
7 for maintenance tasks, procedures, recommended frequency and by whom they should
be performed. Always verify proper operation
of the appliance after servicing.
Always turn off the gas to the appliance before
cleaning. Before re-lighting, refer to the lighting
instructions in this manual. Instructions are also
found on pull-out panels located below the glass
door in the control compartment.
Keep lower 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.
Page
Turn off gas and electrical power
before servicing the appliance.
-
CAUTION
Wear gloves and safety glasses
for protection while doing
required maintenance.
IMPORTANT
Always verify proper operation
after servicing.
Check Burner Flame Appearance
-
Visually check the flame of the burner periodi
cally making sure the flames are steady and not
lifting or floating (see
Glass Cleaning
Note: Clean glass after first two weeks of operation (after Burn-In period is over).
The viewing glass should be cleaned periodi
cally to remove any build-ups caused from the
-
following:
• During start-up, it is normal for condensa
tion to form on the inside of the glass (this
condensation and fog will usually disappear
in a few minutes). This 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.
Use one of the following to clean glass:
• Non-ammonia based household cleaner
• 50%-50% mix of white vinegar & water
• gas stove glass cleaner
Figure 19 on Page 8).
Do not use abrasive cleaners
on glass. Never clean the glass
when it is hot.
WARNING
Do not attempt to touch the front
enclosure glass with your hands
while the fireplace is in use.

Do not attempt to repaint the insert until the
finish is completely cured (see Burn-In Period
on this page). If the surface later becomes
stained or marred, it may be lightly sanded and
touched up with spray paint.
Paint is available at your local authorized Lennox
Hearth Products dealer. Never attempt to paint
a hot insert.
Inspect Wiring
Inspect and clean all wire connections. Ensure
that there is no melting or damage. Inspection

PROCEDURE FOR REMOVING THE STANDARD GLASS DOOR
ASSEMBLY
WARNING
Handle glass door with extreme care! The glass
door assembly is susceptible to damage. Do not
scratch while handling or while reinstalling.
WARNING
Never operate unit without the front glass door
panel in place and secure.
Remove the front door assembly from insert as follows:
1) Pull off top louver and hinge down lower louver (see

BURNER ADJUSTMENT
Flame Appearance and Sooting
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 gradually turn yellow/orange during
the first 6-8 minutes of operation. If after 6-8 minutes the flame stays
blue, or if the flame is orange with evidence of sooting (black tip), the
air shutter may require adjustment.
An appliance operated with an air shutter opening that is too large will
exhibit flames that are blue and transparent. These weak, blue and
transparent flames are termed anemic. If the air shutter opening is too
small, sooting may develop.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
Figure 19
EDVI35 Shown
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 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. Reposition 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.
IMPORTANT
Ensure that the front glass panel is in place and
sealed during adjustment.
