Concentric Air Intake and Vent Terminal GT-150 & 200 Only

If a concentric terminal is used it must be Smith part number GT-82666 or York part number 1CT0303. The concentric terminal must be located at least 12 in, 305 mm, above the normal snow line, Figure 11. Position the air intake pipe on the top or to the side to prevent rain from entering the boiler, Figure 13.

When terminals from multiple boiler installations exit a common wall the following conditions must apply:

1.If limited to two terminals the horizontal centerline distance must be 4 in, 102 mm, or greater than 24 in, 610 mm, to prevent flue gas recirculation. For more than two terminals located along a horizontal plane, the centerline distance between them must be 24 in, 610 mm, Figure 11.

2.If the terminals are located in a vertical plane the centerline distance between them must be at least 48 in, 1220 mm, Figure 12.

Figure 12 - Vertical Concentric Terminal Location

When penetrating an outside wall the concentric terminal must be constrained as shown in Figure 13.The opening through which the concentric terminal passes must be properly sealed to prevent products of combustion from entering the building. The air intake of the boiler must be connected to the terminal!

WARNING: Failure to properly install and seal the concentric terminal can result in excessive levels of carbon monoxide which can cause severe personal injury or death!
