8. Install new IFT-ECM by attaching the wires and other
accessories including the IFT-ACM and IFT-RFM.
See Figure 5.
· Note the RFM is required to enable the Thermostat
function via the IFT-RC150 or IFT-RC400.
9. Locate the IFT-WFM port on the end of the IFT-ECM.
Remove and discard the rubber cover from the IFT-ECM
port.
13. Follow the pairing instructions for your remote and/or
accessories (e.g. IFT-RC400 and IFT-RC150).
Note: You must re-pair the ECM to detect any features
added to the IFT-ACM, including an IFT-RC400 and/or
IFT-RC150 .
Note: If you do not have an IFT-ACM and remote control,
you do not need to pair.
6. Once power has been turned o, proceed to remove from
the old ECM all wires and other accessories including the
ACM and the Radio Frequency Module (IFT-RFM).

7. Remove the rubber covers and verify the 50/30 and LP/
NG switches of the new Wi-Fi enabled ECM are in the
same position as the old ECM you noted in step 4. Make
sure you replace the rubber covers for the two switches.
5. Remove power from any purchased accessory: Fan,
lights, Auxiliary Control Module (IFT-ACM). See Figure 4.
10. Connect the IFT-WFM to the IFT-ECM by aligning the
pins and tabs and pushing the IFT-WFM into the IFT-
ECM until both tabs snap into position. Ensure the
two components are fastened securely to one another.
See Figure 5.
12. Move the selector switch on the IFT-ECM back to
‘Remote’ position. The IFT-ECM will beep and display
three green LED ashes. On the IFT-ECM, locate the
‘PILOT’ button then press and hold for ten seconds. The
IFT-ECM will emit one audible beep for four seconds.
Release the ‘PILOT’ button. The IFT-WFM green LED
will ash every two seconds, indicating it has an open
access point. You can conrm the open access point by
seeing the IntelliFire_XXXX network in the available Wi-
Fi networks on your smart device.
Note: The IFT-RFM is still required for use with a remote to
enable the thermostat function. The room temperature is
measured by a sensor in the IFT-RC150 and/or IFT-RC400
remote control. Without a paired remote, the TEMP function
in the app will not function correctly.
14. Once these steps are complete, your IFT-ECM/IFT-
WFM is ready for setup with the IntelliFire app using
the IntelliFire App Installation Instructions and User
Guide.
11. Restore power to the appliance.
