** I have a fellow inspector that frequently uses the comment: **
· The plastic materials used for the mechanical exhaust vent flues are not listed or labeled for use in enclosed attic areas. This is an “as-built” condition but Per TREC standards of practice we are required to report this condition as a deficiency.
Since I cannot find any information in the IRC or TREC Standards of Practice, I question the validity of this statement. Please let me know where I can find any backup information to verify this statement.
