Does this Heater vent need a heat collar?

Yes, a ceiling support/firestop and insulation dam (if attic) is needed.


Thanks for the info and link.

If it’s a single wall vent it needs a vent thimble (heat collar). Double wall vent can be installed either with a thimble or with adequate clearances to combustibles without a thimble.
