Direct Vent (Co-Linear) Chimney Liner Kits

Direct Vent (Co-Linear) Chimney Liner Kits
Chimney liners for direct vent gas fireplaces & fireplace inserts.
Direct vent (or sealed combustion) uses outside air for combustion instead of inside (room) air. This prevents infiltration of outdoor air into the home, resulting in higher efficiency (no need to heat outdoor air again) and higher indoor air quality.
