the side panel out and away from the unit (see Figure

• Pressure taps for the inlet (IN) and the manifold
(OUT) *see page 49*
•
Switches for the burner (bottom), IFC reset (middle),
and power vent (bottom) *see section below*
• Access to the battery backup
Refer to Figure 17 for a diagram of the control panel.

For convience, the fireplace comes pre-wired for power vent
applications. If needed, to switch into power vent (PV) mode
locate the PV switch above the the IFC Reset. The top rocker
switch with the cover over it controls the mode setting of the
fireplace’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 dis-
connected.
IMPORTANT - Main power must not be connected
to the fireplace 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 fire
-
place on and off via the remote will not correct this.
Quick Tip
- A typical symptom of the fireplace being in
-
advertantly switched to PV mode is a responsive remote
with full control of the Light circuit but no pilot ignition
sequence.
