Sterling Inlet air collar and gasket set for GG series heaters. This allows you to connect an air inlet pipe to the Sterling GG heaters without the concentric vent kit. With this setup you will have separate exhaust and intake exit points in your structure. The GG heater access panel gasket
is also needed with this setup to provide an airtight seal around the access panel.
This comes already installed on most new Sterling GG heaters. Please check with us if you plan on ordering this with a new GG heater.
Sterling GG30, GG45, GG60, and GG75 use 4".
Sterling GG90, GG105, and GG120 use 5".
