Re: Who needs 6" of clearance for single wall
Single wall? In an attic? There's more than a clearance issue.

Re: Who needs 6" of clearance for single wall
Flue should be double-wall constructed where it passes through a ceiling or roof decking and have a (1) inch clearance from combustible material.
6" clearance? Not sure what your meaning.

Re: Who needs 6" of clearance for single wall
Maybe I wasnt aware that single wall vent was not allowed in attic, my bad. But as far as the 6" rule as far as I know single wall vent has to be 6" from any combustibles. If anyone can educate me further I welcome it.

Vent connector clearances:
gas single walled- 6"
B-vent- 1"
Oil single walled-18" unless listing states 9"
L-vent- 6-9" per listing except for pellet venting
pellet L vent-1-3" depending upon listing
wood single walled-18"
wood double walled close clearance -6"
No single walled connectors outside the thermal envelope such as attics or crawl spaces. Too much condensation and weaker draft.
Keep the fire in the fireplace.
