Sterling GG heaters can be converted to separated combustion when this kit is added to the heater. Separated combustion heaters draw combustion air from outside to ensure that the unit will always have plenty of fresh clean air. The fresh air supply reduces common concerns about dusty, dirty, or high humidity applications. You can also decrease heating costs by as much as 10% because no cold outside air is being sucked into the structure when the heater is running. Pipe must be purchased separately.

What does the concentric vent kit do? The concentric vent kit allows the air intake and exhaust to vent to the outside wall with only one hole as shown in the picture below. Use for horizontal or vertical venting.


Concentric vent kits include:

  • Concentric vent box
  • Inlet air screen
  • Deflector disc
  • Vent cap
  • Air intake adapter
  • Access panel gasket
  • High-temp silicone

(Model X7-4) The 4" concentric vent kit is for models GG30, GG45, GG60, and GG75.
(Model X7-5) The 5" concentric vent kit is for models GG90, GG105, and GG120.


Please note: The concentric vent kit does not include any piping. We offer pipe kits for this system which must be purchased in addition to this kit to have a complete vent system.

Quality kit with everything you need to go concentric!

Rating:
I'm doing a self install and the ACF Greenhouse kits have proven excellent for a rookie like me. I went with the concentric exhaust kit to increase the efficiency of my GG75 in the garage. It is great to have everything I'd need packaged together - and comes with detailed instructions that were easy to follow. Five stars for sure!
