MULTIFUNCTION REMOTE OPERATING INSTRUCTIONS
Using the Fireplace without a Remote Control
The fireplace can be turned ON (HI only) and OFF with the wall
switch. The fireplace flame ON/OFF is the only function that will
operate; no flame adjustment, light or blower will work when using
the wall switch. The wall control switch should be turned OFF
when the fireplace is not being used for extended periods of time.
Battery Backup Operation
Install batteries (See initialization sequence on page 69). In
case of power loss, the fireplace will switch to battery mode
automatically. The fireplace will operate normally without the fan
or light control when in battery mode.
Low Battery Detection
When the backup batteries are low, a double-beep will be emitted
when the module receives an on/off command. No commands
will be accepted until the batteries are replaced or the A/C power
is restored.

Lockout State Definition
A lockout state is reached when an ignition error occurs. The
lockout state will remain set in memory as long as the power
supplies are applied.
This could mean both an anomalous flame detection and/or too
many unsuccessful ignition tries.
This state is a safe condition for the fireplace and is entered
automatically by the IFC board.
When the IFC board gets into lockout state:
1. both the Pilot and the Main Burner solenoids in the gas valve
are de-energized;
2. a diagnostic code is sent through the diagnostic red LED.
3. the IFC board will ignore any burner ignition command
and remain in the OFF state unless the unlock command
sequence is met.
The causes of lockout must be investigated under safe conditions
by the user and/or the service personnel.
To reset the IFC from a lockout state, perform the following
procedure:
Turning the system power supplies (to the wall control or
remote control) OFF for two or three seconds and then
restoring a power supply back on.
The return of the system to normal operation must be checked
under safe conditions by the user and/or service personnel.
