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 sup-
plies are applied.
This could mean both an irregular flame detection and/or too
many unsuccessful ignition attempts.
This state is a safe condition for the appliance 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 se-
quence 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 pro-
cedure:
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.
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 us
-
ing 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 44). In case
of power loss, the fireplace will switch to battery mode automati
-
cally. 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.
MULTIFUNCTION REMOTE OpERATING INSTRUCTIONS
1
If the IFC is signaling lock out: The
board should be unlocked to
reinitiate a pilot flame ignition (for
the correct unlock sequence refer
to the IFC Use and Installation
Instructions).
Is the IFC board in
lockout?
1.
Verify the electrical connections’ integrity and
make sure they are in accordance with the relevant
system wiring diagram. If necessary, replace the
wire harness.
2.
Replace the IFC board.
Was spark observed
at the Pilot Hood
before the IFC board
locked out?
1.
Check the spark electrode positioning - adjust
as necessary.
2.
Replace the pilot assembly.
3.
Verify the electrical connections’ integrity and
make sure they are in accordance with the
relevant system wiring diagram. If necessary,
replace the wire harness.
4.
Replace the IFC board.
1.
Verify the electrical connections’ integrity and
make sure they are in accordance with the
relevant system wiring diagram. If necessary,
replace the wire harness.
2.
If pilot flow adjuster screw is not sealed,
check if pilot flow adjust screw is set correctly in
accordance with the appliance manufacturer
instructions. If necessary, correct it.
3.
Replace pilot tube or complete pilot
assembly.
4.
Replace the pilot orifice with a new orifice of
correct size and type or replace the pilot assembly.
Under all circumstances follow the appliance
manufacturer’s service instructions.
5.
Remove the provided wiring harnesses from
Ev1 of gas valve (red base), and verify voltage at
ignition between the Ev1 terminal and the ground
connection on the valve body. If the voltage is
greater than 0 then Replace Valve. Otherwise
replace IFC.
Spark continues
while the pilot is ON.
