Sterling GG Heater Vertical Vent Kits
Sterling GG Concentric Vent Kit
Add Separated Combustion to the GG with the Optional Concentric Vent Kit
Sterling Vent KitSterling 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. 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 above. Use for horizontal or vertical venting.

The concentric vent kit includes: (shown above) the concentric vent box, inlet air screen, deflector disc, vent cap, air intake adapter, access panel gasket, and high-temp silicone More vent information
