Frequently Asked Questions/Troubleshooting (continued)
Symptom
IFT -RC400 displays the following
message on-screen:
Appliance safely disabled.
Call dealer for service.
In addition the LED indicator on
the IFT-ECM will flash twice red
and once green indefinitely.
The room temperature displayed
on the IFT-RC400 is either slow or
quick to respond while operating in
thermostat mode.
The appliance turns OFF the flame
after extended periods of operation
IFT-RC400 does not pair or unpair
from the IFT-ECM
IFT-RC400 displays the following
message on-screen:
Fan will turn on
within 3 minutes"
IFT-RC400 displays the following
message on-screen:
'Replace Remote Batteries' or
'Must Replace Remote Batteries to
Operate Appliance'.
The flame height on the IFT-
RC400 does not appear to be
doing anything.
IFT-RC400 is displaying an
incorrect brand.
After turning flame ON using
display, the flame does not turn
ON immediately and instead a two
minute timer is displayed.

Possible Cause
Ignitor wires (orange) or flame
sense wire (white) is shorted
to chassis ground.
IFT-ECM is unable to sense
flame due to contamination on
flame sensing rod.
Ignitor and sense wires are
incorrectly wired.
Pilot appears to be 'missing'
sparks from the ignitor.
IFT-RC400 is placed at a very
short distance or too far away
from the appliance.
IFT-RC400 is placed in the
path of an air draft or vent.
Flame Modulation
9 hour safety shutdown timer
IFT-ECM is not connected to
its power source
Noisy radio environment is
preventing IFT-ECM and IFT-
RC400 from communicating.
Functioning as intended.
Low battery in IFT-RC400.
Stepper motor is not
connected.
IFT-RC400 was programmed
incorrectly.
Power vent is installed on the
appliance.
Corrective Action
Verify that pilot sense and ignitor leads are not shorted to chas-
sis ground and the protective covering has not melted or is cut.
Replace pilot if necessary.
Measure pilot sense lead resistance. If more than 1 Ohm,
clean flame sensor rod with fine steel wool and measure re-
sistance again. If resistance still > 1 ohm, replace pilot.
Verify that the sense lead (white) is securely terminated to the
"S" terminal on the IFT-ECM, and that the ignitor lead (orange)
is terminated to the "I" terminal on the IFT-ECM.
Verify that pilot sparks 8 secs ON, 2 secs OFF, and discharges
consistently between the hood and the ignitor electrode. Verify
spark gap is 0.095 to 0.135 inches, and adjust if necessary.
Try to keep the IFT-RC400 close to the appliance but not di-
rectly in front of it.
Move the IFT-RC400 away from the direct path of air flow.
The IFT system is designed to automatically adjust the flame
intensity based on the difference between the desired room
temperature, and actual temperature. In thermostat mode,
the hearth appliance will start in HI flame, but as the actual
temperature approaches the desired set temperature on the
remote, the flame intensity will automatically decrease. Auto-
matic flame modulation will result in more control of the tem-
perature, but will cause the appliance to cycle OFF/ON less.
This is normal behavior. The appliance has a safety timer that
will automatically turn OFF the flame after nine hours of unin-
terrupted operation.
Verify IFT-ECM is connected to power and the three position
switch is set to REMOTE. If operating off battery backup,
ensure that all four batteries are NEW. Follow pairing process
listed in section F.
The IFT-ECM and IFT-RC400 operate on the 915MHz radio
band. Allow up to 10 minutes for the IFT-ECM and IFT-RC400
to establish contact. If the problem does not get resolved try
powering OFF and ON both the IFT-ECM and IFT-RC400 and
perform pairing function listed in section 2F.
The appliance has a three minute delay timer before the fan is
turned ON. This allows the air surrounding the appliance to be
heated before being pushed into the room.
Install new batteries in the IFT-RC400.
Check if the 4 pin wiring harness from the stepper motor is
connected to the IFT-ECM.
Call dealer to have them program the IFT-RC400 with correct
branding. IFT-RC400 is still fully functional and the appliance
is unaffected.
This is expected behavior and the two minute timer is called a
pre-purge timer. The flame will turn ON at the expiration of the
timer.
