Venting Below Grade
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.

Outdoor Horizontal Venting
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.
3” pipe can only be used for Lx150-200 models;
4” pipe must be used for the Lx300-400 models.
3.
All normal termination clearances are maintained.
4.
All exterior exhaust vent pipes are insulated with
3
½” [89 mm]
- ID for Lx150-200, or 4
½”
[114
mm] - ID for Lx300-400, and 6
½”
[165 mm] ID
for Lx800, ½
”
[13 mm] thick, Closed Cell
Foamed Polyolefin Tubing (i.e., “Tundra Seal
Plus” or equivalent).
5.
The pipe is supported every 24
”
[610 mm].
6.
The exhaust and inlet are sloped back to the
appliance ½
”
elevation for every linear foot [13
mm for every linear 305 mm].

Existing Chimney Chase Way
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
appliance.
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.
