Determine exact position of your fireplace, including hearth height, width, and depth, (if applicable). If possible, place fireplace in such a
manner that vent termination will be placed between two studs, eliminating the need for additional framing.
Follow vent pipe manufacturer’s installation instructions for horizontal terminations. Include
required 3” (76mm) top clearance and 1” (25mm) sides and bottom clearances for approved
rigid vent systems and the Kozy Heat #800-1 series flexible vent system.
HORIZONTAL TERMINATIONS
Follow vent pipe manufacturer’s installation instructions for vertical terminations. A minimum 1” (25mm) clearance on all sid
es of
vertical vent pipe must be maintained.

FRAMING
If masonry is to be used (optional), prepare the necessary foundation for the masonry load. When masonry construction is being used, a
lintel must be used over the top of fireplace to support the added weight.
See-Thru applications: #617 Lintel Iron
Pier applications: #788-T Lintel Iron
