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.

Please note: Check with your local inspector/installer before using this instead of the concentric vent kit in a residential application as it may not pass inspection.

Sterling GG30, GG45, GG60, and GG75 use 4".
Sterling GG90, GG105, and GG120 use 5".
