Induction blower seal
I just replaced the induction blower on my Trane x80 furnace. The seal between the former blower and the furnace was a very fibrous gasket that essentially disintegrated when I took it out.
I replaced the blower with a Fasco A143, but it didn't come with a gasket or seal. I've seen suggestions of using a bead of silicone around the blower...
How essential is this gasket? Is this something that needs to be fixed ASAP, or can I put it off until the weekend?
Are there any suggestions as to what type of gasket or silicone to use to seal the blower?
