Sterling GG Heater
Vertical Vent Kits
Concentric Vent Kit
Separated Combustion to the GG with the Optional Concentric Vent Kit
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
The vertical pipe kits include:
(items in red text shown at left)
- 5' of UL1738 stainless steel

Please note: Vertical
installations vary, and additional pipe may be needed. Please read the Sterling
GG Concentric Vent Manual to determine what your venting needs are.
The concentric vent kit is not included with any of the pipe kits. It must be
