heater rebuild

[Bob Labuz <yellowtr@adelphia.net>]

I am restoring a TR4 heater and during the teardown I noticed what I think was 
the remains of a poly-foam backing on the heater door that swings open to 
allow air to flow to the feet. Is that true? If so, is the poly-foam supposed 
to cover the entire door as a seal?

Thanks,
