WARNING! Risk of Fire! Coaxial to colinear venting con-
figuration may only be used in existing non-combustible
chimney. Installation in any other venting application
could cause fire.
Prior to installing the gas appliance:
• Have the chimney and adjacent structure inspected
and cleaned by qualified professionals. Hearth & Home
Technologies recommends that NFI or CSIA certified
professionals, or technicians under the direction of certi-
fied professionals, conduct a minimum of a NFPA 211
Level 2 inspection of the chimney.
• Replace component parts of the chimney and fireplace
as specified by the professionals.

• Two 30 feet sections of flexible vent pipe (3 inches Ø).
One section is used to draw combustion air and the other
section is used to expel exhaust gases.
• One vertical termination cap.
