American International PG10*34-100-2NV or 2PV VERTICAL TERMINATIONS 100,000 - 150,000 BTU/HR

VERTICAL TERMINATIONS (100,000 - 150,000 BTU/HR)

When 3 inch pipe is used between the water heater and the roof, reduce it to 2 inch pipe before penetrating the roof. A maximum of 18 inches of 2 inch pipe may be used between the 3 inch transition and the inside of the roof.

The vertical inlet air termination requires a return bend or two short or long sweep radius 90 elbows to keep the inlet downward and prevent entry of rain. These elbows are considered part of the termination and should not be included when calculating the maximum allowable vent pipe length. Refer to figure 9A for the proper location of the air inlet with respect to the exhaust outlet termination. The vertical exhaust outlet termination is a 2 inch pipe which terminates at least 12 inches above the inlet air termination.

The air inlet and exhaust outlet terminations must be at least 12 inches above the roof line or anticipated snow levels. See figure 9A below.

Note: See “Venting Additional Polaris® Units” below if installing more than one Polaris® gas water heater.
