Hi Jim (W9UUM)

As Jim (K9YC) said, call the vendor and inquire about input line filters.

If you hit a dead end you can check out my solution for treadmills that
also have variable speed drives, and you should be able to apply a similar
technique on your furnace using part or all of my solution for treadmills.

Here is a link to my website that describes my treadmill RFI solution :
