1. Remove outer glass (see page 2).
2. Remove front louver (see page 23).
3. Remove center fan assembly (see page 13).
4. Check sail paddle for full motion range by activating
with your nger; it should return to its fallen position
when released.
If not, check for binding sail arm or counterweight;
adjust as needed. Activate the switch several times
to work the internal grease if they replace isnt used
often. The paddle may need further adjustment
if it does not return to the lowest position upon
release. Press slightly on paddle while supporting
at counterweight to adjust sensor. Be gentle,
sensor is delicate and could damage easily.

Air Shutter (Venturi)
The air shutter plays a very important role in ame
appearance and combustion quality. The shutter adjusts
how much air gets mixed with the gas before it ignites.
We recommend starting the replace and allowing it to
heat up for 15 minutes before making nal adjustments.
Adjust the shutter as follows:
1. Remove outer right glass(see page 22).
2. Remove right louver (see page 23).
3. Locate air shutter linkage knob (see photo) and
adjust as needed.
Lean (more primary air): Pull knob outward to make
ame appear more blue and low.
Rich (less primary air): Push knob inward to
make ame appear more yellow and tall. Flame
will continue to richen up during operation
creating a potential for gradual soot build-up.
Pilot Light
The pilot ame should cover 1/4” to 1/2” (7 to 13mm) of
the ame sensor (see photo). The pilot ow adjustment
is set to maximum from the factory and should not need
adjustment. However, should the need arise, adjust pilot
ame as follows:
1. Remove outer right glass (see page 22).
2. Remove right louver (see page 23).
3. Locate the pilot adjustment screw
on the valve (see photo).
4. Turn the adjustment screw to alter
the pilot gas ow as needed.

Flame Sensor
• If you cannot attain a healthy ame by making air
shutter adjustments, you may have the incorrect
restrictor setting or a venting problem.
• Propane units have very little to no adjustment.
• More details can be found in the venting section of this
manual.
• Caution: Wear heat resistent gloves when making
adjustments to the air shutter. Perform nal
adjustments after 15 minutes.

Remote Syncing
The remote should be synced to your replace by your
installer during installation.
Your remote may gradually lose its RF connection strength
over time. Resync the remote if this happens or if the
batteries have been changed. Resync remote as follows:

PANEL
IN BETWEEN FRONT
GLASS AND FIREPLACE
CABINET

BUTTON
POWER VENT
SWITCH
(INSTALLER USE
ONLY)
1. Locate the switch tool supplied
with your replace (see photo).
2. Locate the hidden switch panel
mounted on inner replace cabinet.
3. Slip the tool in between the front
glass and cabinet and press the middle
switch. You will hear 3 beeps from the IFC.
4. On hearing the 3 beeps, press the ON/OFF
key on your remote; you will hear 3 more beeps
to acknowledge successful remote syncing.
5. Press the ON/OFF key again to turn o the
remote. The remote is now ready to use.
MAIN
BURNER
SWITCH
Power Vent (PV) Switch
For convience, the replace comes pre-wired for
power vent applications. If needed, to switch into
power vent (PV) mode locate the PV switch next to
the Remote Sync Button. The far left rocker switch
with the cover above it controls the mode setting of
the replace's IFC. From the factory the - symbol is
down, press the rocker switch so that the O symbol is
down. To clarify:
- symbol down = Direct Vent (DV) mode
O symbol down = Power Vent (PV) mode
If for some reason the IFC needs to be switched back
to DV mode simply press the switch again with main
power disconnected.
IMPORTANT - Main power must not be connected
to the replace prior to switching between DV
and PV modes. If power is connected the IFC will
remain in the previous mode until power is removed.
Turning the replace on and o via the remote will
not correct this.
Quick Tip - A typical symptom of the replace being
inadvertantly switched to PV mode is a responsive
remote with full control of the Light and AUX circuits
but no pilot ignition sequence.
