AMW has have found that the disc is not needed in M1350WW. We went to a

nozzle insulation washer. The change in smoke element can be determined by
the wall thickness of the smoke element paper liner. The new smoke element
has ~3/16" wall thickness .vs. the original wall thickness that matches the
We apologize that the motor assembly instructions were not updated on some
product shipped this summer. The fiber disc needed to be removed from the
parts list and the assembly instructions on the M1350WW. If you end up
with a motor with a disc (and the larger smoke element), it should be used

Hope this answers your question. Since we do not have time to regularly
monitor the news groups to answer questions, or If you need any further
please let us know using the sales "at" animalmotorworks.com email address.
Thanks for buying Animal Motor Works products.
