Product Features

Flexible Colinear Venting System

The HHT Colinear 30/4 Direct Vent Kit is designed to vent a gas fireplace insert through an existing chimney using a colinear vent configuration, separating intake air and exhaust gases for safe and efficient operation.

Dual Liner Configuration for Proper Venting

This kit includes two flexible aluminum liners sized for gas insert venting.

• (1) 30' liner (3") for extended chimney runs
• (1) 4' liner (3") for shorter vent connections
• Designed to simplify installation in various chimney heights

The dual-liner system ensures proper combustion air intake and exhaust venting, as required by modern direct-vent gas inserts.
