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 fi lm
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
IMPORTANT
Do not use abrasive cleaners
on glass. Never clean the glass

WARNING
BURNER ADJUSTMENT
Flame Appearance and Sooting
Proper fl ame appearance is a fl ame which is blue at the base and becomes
yellow/orange in the top of the fl ame. When the insert is fi rst lit, the
entire fl ame may be blue and will graduallay turn yellow/orange during
the fi rst 6-8 minutes of operation. If after 6-8 minutes the fl ame stays
blue, or if the fl ame 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 fl ames that are blue and transparent. These weak, blue and
transparent fl ames are termed anemic. If the air shutter opening is too
small, sooting may develop.
Never operate unit without the front glass door panel
in place and secure.
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
Release latch on
each side (below door)

2) Swing the bottom of the door outward (see Figure 12) and lift it
off of fi rebox top. Set door aside in a safe place.
Burner Flame Appearance
Figure 13
EBVI25 Shown
Sooting is indicated by black puffs developing at the tips of very long
orange fl ames. 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
fl ames and lack of combustion air entering the air shutter opening. To
achieve a warm yellow to orange fl ame 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 fl ames
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.

Burner Adjustment Procedure
WARNING
Air shutter adjustment should
only be performed by a qualifi ed
professional service technician.
CAUTION
The adjustment rod and nearby
appliance surfaces are hot. Exercise caution to avoid injury while
adjusting fl ame appearance.
If the burner fl ame appearance differs greatly
from what is shown in Figure 13 (see Burner Flame Appearance), some adjustment from
the factory setting for the air shutter gap may
be necessary (to compensate for variables
in the installation and fuel such as, BTU
value/composition, gas pressure, specifi c
gravity of gas, altitude, etc.).
See Table 5 on Page 8 for Burner Air Shutter Adjustment Guidelines.
Initially, always position the air shutter to the
factory setting as shown in Figure 14 (adjustment 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 fl ame continuously. If it appears weak
or sooty as previously described, adjust the
air shutter to a more open position until the
proper fl ame appearance is achieved.
CAUTION
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.

BLOWER OPERATION
When the insert heats up, the blower will automatically be turned on by the fan disc located
under the fi rebox bottom on the front left side.
It will come on at the speed determined by the
rheostat located on the side surround panel (see
Figure 4 on Page 4). To adjust the blower speed,
dial the rheostat to the desired speed setting.
Rotate the dial down (clockwise), just past the
click (the fi rst 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
THIS FIREPLACE HAS BEEN ALTERED TO
ACCOMMODATE A FIREPLACE INSERT
AND SHOULD BE INSPECTED BY A QUALI-
FIED PERSON PRIOR TO RE-USE AS A
CONVENTIONAL FIREPLACE.

• Clean or replace pilot orifi ce
• Check connection at valve
• Ensure thermocouple is fully inserted into pilot assembly. Clean and/or adjust
pilot for maximum fl ame impingement on thermocouple if necessary.
• Replace thermocouple
• Turn burner off/on switch on and/or refer to instructions provided with optional
thermostat or remote control, if applicable.
• Check wall switch and wires for proper connections. Refer to Millivolt Wiring
Diagram (Page 12, Figure 28). Jump the wire across terminals at the wall switch,
if the burner comes on, replace the defective wall switch. If okay, jumper the
wires across the wall switch wires at the valve. If the burner comes on, wires
are faulty or connections are bad.
• Refer to Millivolt Wiring Diagram (Page 12, Figure 28). Electrically bypass
components one at a time and replace defective item.
• Check thermopile with millivolt meter. Take reading at thermopile terminals
of gas valve. It should read 325 millivolts minimum with optional wall switch
“OFF.” Replace faulty thermopile if reading is below specifi ed minimum.
• Check burner orifi ce for blockage and remove.
• When turning on the burner using a Remote Switch,* ensure that the
standard 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 fl ame for maximum fl ame impingement on thermocouple. See Page 11, Figure 25.
• Examine venting system for blockage. Remove any blockage.
• Open a window to see if the problem is corrected.
• WARNING: NEVER USE AN OPEN FLAME TO CHECK FOR LEAKS.
After the gas company or fi re department has given clearance to re-enter the
dwelling, have a qualifi ed technician test all gas joints from the gas meter to
the gas heater regulator for leaks using a gas leak test solution (also referred
to as bubble leak solution).
• Ensure all openings (fresh air inlets) in the insert are free from dust and debris.
Recheck these areas periodically.
• Ensure ceramic logs are in their correct positions.
• Check for fl ue blockage, disconnected fl ue, improper installation. Make
appropriate corrections.
