WALL TERMINATION (WT)
The Wall Termination is utilized when an appliance is
exhausted out of the sidewall of a building. The system includes
a duct Horizontal Termination, Wall Thimble, Thimble Clips, and
Wall Flashing.
BASIC eVent WALL TERMINATION ASSEMBLY
Step 1:
Cut an opening in the wall just large enough to allow
the Wall Thimble to penetrate the wall. Keep the Wall
Thimble flush with the outside face of the wall
.
Figure 13 – Installation of the Wall Thimble
Step 2:
Utilizing the Wall Thimble Clips, secure the Wall
Thimble to the inside of the wall by fastening the clips
to the Wall Thimble and the wall being penetrated.
Space the clips equally around the perimeter of the
Wall Thimble to ensure tight installation.
Step 3:
Center the Horizontal Termination in the Wall
Thimble. A minimum of 3" of inner liner of the
Horizontal Termination must penetrate past the
outside of the wall and Wall Thimble. See figure 14.
Figure 14 – Installation of the Wall Termination
Step 4:
Mount the Wall Flashing over the Wall Termination
sealing the gap between the Wall Thimble and the wall
opening. Level the Flashing and seal around perimeter
of the Inner Liner with a bead of silicone sealant.
DRAIN TEE CAP (DTC)
The eVent SW, eVent & eVent Plus2 has a 1" drain pipe that
must be connected to a suitable drain.
The Drain Tee Cap must be connected at all times to a suitable
drain. Upon entering the vent, rain will wash down and
remove any corrosive combustible residue. The Drain Tee Cap
must be installed with sealant at its mating surfaces with the
flanged joint. This will ensure that moisture is drained through
the drain as intended and will provide a tight seal. The Tee Cap
can be installed for inspection access as required.

30, 45 and 90 DEGREE ELBOWS (30L, 45L and 90L)
These elbows must be protected from the effects of thermal
expansion.

45 DEGREE LATERAL and REDUCING 45 DEGREE LATERAL TEE
(45LT AND R45LT)
For venting systems that require a 45 degree entry to the
vertical vent, the 45 Degree Lateral Tee (45LT) or Reducing 45
Degree Lateral Tee (R45LT) may be used. The 45 Degree
Lateral Tee should be supported in the same way as the 90
Degree Tee. When properly supported, the 45 Degree Lateral
Tee will support 50 feet of vertical vent and may be installed
with a Drain Tee Cap or End Cap.

90 DEGREE WYE (90Y)
The Wye fitting is used when the vertical vent is located between
two boilers and a low‐pressure loss system is required. The Wye
should be installed with the usual precautions observed for
thermal expansions.
