IMPORTANT
Always verify proper operation
after servicing.
Appliance operation may be controlled
through a remotely located optional wall
thermostat or remote control.
Check Burner Flame Appearance
Inlieuofremotecontrolorremotewallthermo-
stat operation, the appliance must be operated

Glass Cleaning
7. Disconnect wires from the blower.
8. Lift blower up and pull it out from back
opening of firebox (see Figure 9).
9. To reinstall blower, reverse Steps 1
through 8.
Model EBVI25
Note: Clean glass after first two weeks of
operation (after Burn-In period is over).
Remove 10 Screws (use phillips screwdriver)
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.

BURNER ADJUSTMENT
PROCEDURE FOR REMOVING STANDARD
GLASS DOOR ASSEMBLY
Flame Appearance and Sooting
Properflameappearanceisaflamewhichisblueatthebaseandbecomes
yellow/orange in the top 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
blue, or if the flame is orange with evidence of sooting (black tip), the
air shutter may require adjustment.
WARNING
Handle glass door with extreme care! The glass
door assembly is susceptible to damage. Do not
scratch while handling or while reinstalling.
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.
WARNING
Neveroperateunitwithoutthefrontglassdoorpanel
in place and secure.
Burner Flame Appearance
Remove the front door assembly from insert as follows:
1) Open the two latches below the glass door as shown in Figures
11 & 12.
Glass Door
EBVI25 Shown
Figure 13
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.
Release latch on
each side (below door)
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.
Figure 11
2) Swing the bottom of the door outward (see Figure 12) and lift it
off of firebox top. Set door aside in a safe place.
IMPORTANT
Ensure that the front glass panel is in place and
sealed during adjustment.

Burner Adjustment Procedure
CAUTION
WARNING
Air shutter adjustment should
only be performed by a qualified
professional service technician.
Carbon will be produced if the air shutter is closed too much. Any
damage due to carboning resulting from improperly setting the air
shutter is not covered under the warranty.
The following chart is provided to aid you in achieving the correct air shutter adjustment
for your installation.
CAUTION

The adjustment rod and nearby
appliance surfaces are hot. Exer-
cise caution to avoid injury while

Installation Instructions
See Table 5 on Page 8 for Burner Air Shutter
Adjustment Guidelines.
WARNING
Initially, always position the air shutter to the
factorysettingasshowninFigure14(adjust-
mentrodislocatedinthelowercontrolarea).
This can be done by moving the adjustment
rodupordownaccordingly. Allowtheburner
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.
If logs are not installed according to the directions shown here, flame
impingement and improper combustion could occur and result in soot
and/or excessive production of carbon monoxide (CO) - a colorless,
odorless, toxic gas.
Carefully install the seven-piece log set into the firebox as shown in these instructions. All
logs should fit onto corresponding pins and/or log stoppers. This will ensure a proper flame
and safe combustion.
Note: Place some vermiculite around burner before installing logs (see Figure 24). The entire
bag of vermiculite will NOT be used.

FOR YOUR SAFETY, READ BEFORE LIGHTING
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION
MAY RESULT CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
A. This appliance has a pilot which must be lighted with a piezo

exactly.
•
•
Do not use any phone in your building.
Immediately call your gas supplier from a neighbor’s
phone.
•
If your gas supplier cannot be reached, call the fire depart-
ment.
B. BEFORE OPERATING, smell all around the appliance area for
gas. Be sure to smell next to the floor because some gas is
heavier than air and will settle on the floor.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If the knob will not push in or turn by hand,
do not try to repair it, call a qualified service technician. Force
or attempted repair may result in a fire or an explosion.
WHAT TO DO IF YOU SMELL GAS
•
•
•
•
Extinguish any open flame.
Open windows.
Do not light any appliance.
Do not touch any electrical switches.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.
LIGHTING INSTRUCTIONS
1. STOP! Read the safety information above on this page.
2. Access the lower control compartment.
3. Turn remote wall switch to “OFF.”

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 – It should be between 1/8” and 3/16.” If the gap is out of this
range, adjust the gap or replace the pilot assembly. See Page 11, Figure 25.
D. Incorrect lighting procedure
• Carefully follow the lighting instructions on Pages 15 &16 or as found in the
insert control compartment.
E. Gas supply problem
