4. An IFT-ECM reset is required if the module is in a
lock-out condition. When this occurs, the appliance
is shut down and the IFT-ECM status indicator LED
will be blinking a RED/GREEN error code along with a
one-time audible double- beep. If the IFT-ECM is in a
lock-out condition, refer to the troubleshooting chart to
interpret the error code and take corrective action as
required. To reset the IFT-ECM after a lock-out error
:
CAUTION!
Risk of burns!
Appliance surfaces are hot
when operating and during cool down. Use care and
wear gloves when opening the front and accessing com-
ponents inside the appliance.
- Be aware the appliance may be HOT, use
care in accessing the IFT-ECM.
- Set the IFT-ECM 3-position selector switch to
OFF position.
The IFT-RC150 remote is an option for this model. The
IntelliFire Wi-Fi module (IFT-WFM) is also an option.
1. The Electronic Control Module (IFT-ECM) has a
three-position ON/OFF/REMOTE selector switch
that must be set for proper operation. See Figure
3.6. When changing switch positions, it is important
to pause in each position for 1-2 seconds.
OFF Position:
The appliance will not respond to any commands
from a wired wall switch, IFT-RC150 or IFT-RC400
remote controls. The unit should be in the OFF
position during service, fuel conversion, and to
reset the IFT-ECM in the event the system goes
into a LOCK-OUT mode as the result of a system
error. When switched to the OFF position while the
appliance is operating, the system will shut down.
ON Position:
The appliance will ignite and run continuously at
the HI flame setting. No adjustment in flame height
is possible.
Remote Position:
The remote position allows operation of the
appliance from a wired wall switch, IFT-RC400 or
IFT-RC150 remote controls. The IFT-ECM switch
must be in this position to pair the IFT-ECM with the
IFT-ACM (if installed), and/or IFT-RC400 and IFT-
RC150 remote controls. See the IFT-RC400 or IFT-
RC150 installation manual for detailed instructions
on pairing the IFT-ECM with the remote controls.
After successfully pairing a IFT-RC400, all installed
accessories can be controlled by the IFT-RC400
(see IFT-RC400 user manual). The RC150 allows
the user to turn ON/OFF the flame in the appliance
and activate the Cold Climate mode if desired. The
IFT-ECM has a safety feature that will automatically
shut down the fireplace after 9 hours of continuous
operation without receiving a command from the
IFT-RC400 or IFT-RC150.
2. If multiple control options are installed, the IFT-ECM
will respond to the last command from the wired wall
switch, IFT-RC400 or IFT-RC150. The wired wall
switch is NOT available if a Power Vent is used.
The IFT-ECM has a safety feature that will
automatically shut down the fireplace after 9 hours
of continuous operation in the ON position, except
when operated in active thermostat mode.
3. The Pilot button on the IFT-ECM activates the Cold
Climate function of the fireplace. This function lights
the pilot flame ONLY to provide enough heat in the
firebox to reduce condensation in cool, high humidity
ambient conditions. To activate the Cold Climate
press and hold the Pilot button for one second and
release. The IFT-ECM will flash two green LED blinks,
beep twice and light and rectify the pilot flame when
pressed to activate. To turn off Cold Climate, press
and hold the Pilot button for one second and release.
The IFT-ECM will flash one green LED blink, beep once
and shut down the pilot flame. If remote controls are
paired with the IFT-ECM, this feature can also be
activated with the IFT-RC400 and/or IFT-RC150.
This model is shipped from the factory equipped with the
IFT-RC400 remote.
