Trinity Ts

For installations that exit the wall below grade:

1. Excavate site to a point below where the pipes

are to exit as shown.

2. Ensure that the wall is fully sealed where the

pipes penetrate the wall.

3. The Vent/Air-intake piping MUST be secured

to the side of the building above grade, as

shown, to provide rigidity.

4. NTI Provides a mounting bracket PN. 82075 for

securing the exhaust pipes.

5. Ensure that the Vent/Air-Intake clearances are

maintained, see Section 5.0 for details.

Vent piping outside the Building is permitted under

the following conditions:

1. The maximum length outside the building is 20

feet [6.1 m]. Note that outdoor length must be

included in the overall vent length calculation.

2. All normal termination clearances are maintained.

3. All exterior exhaust vent pipes are insulated with

- ID, ½" [13 mm] thick, Closed Cell

½" [89 mm]

Foamed Polyolefin Tubing i.e., "Tundra Seal

Plus" or equivalent.

4. The pipe is supported every 24" [610 mm].

5. The exhaust and inlet are sloped back to the boiler

½" elevation for every linear foot [13 mm for

every linear 305 mm].

It is permissible to use an existing chimney as a chase

way to run the Vent/Air-Intake piping as long as:

1. The chimney is not being used by any other

boiler.

2. Flue gases don't enter the vacant chimney.

3. Only Trinity certified venting materials are used,

see Section 4.0.

4. Vent lengths are within the maximums specified.

5. The top of the chimney is capped and the

Vent/Air-Inlet pipes are flashed to prevent

leakage into the vacant chimney.
