Installation Note

This kit is made for side wall routing where a clean 3 in exhaust run and 4 in fresh air connection are part of the heater plan. That makes it a handy choice when you are planning a garage heater installation and want the fresh air side handled at the same time. Always follow your heater manufacturer's installation manual and local codes when installing a heater in a garage.

For a radiant tube heater setup, the right venting pieces can make the whole job feel less like a parts chase and more like a solid garage upgrade. Match the kit to your heater requirements, plan your wall route, and get the shop heat project buttoned up with confidence.
