B. TR342 and TV342 Telescoping Round Termination Cap
•
The uppermost chimney section must terminate no more than 14-1/2 in. (368 mm) below the top of the fl ashing collar on
the chase top. See Figure 3 for additional details.
• Position the telescoping round termination cap above the collar of the chase top and lower the cap assembly until the
stainless steel telescoping slip section engages a minimum of 4 in. (102 mm) into the uppermost chimney section. Push
the termination cap down until the three support brackets contact with the chase top collar.
• Attach the three support brackets to the chase top collar with the screws provided.
•
Wrap the storm collar around the outer slip section.
Fasten the ends of the storm collar together with a
screw at the bottom and a nut and bolt through the
clamp lock at the top. Slide the storm collar down
until it contacts the chase top and tighten the clamp
lock.
• Caulk the gaps between the outer slip section
and the top of the storm collar to prevent leaks.
Any seams along the storm collar must also be
sealed.
C. Shrouds
• Field Constructed Shrouds
- Different shroud designs have been tested for Hearth Technologies fi replace systems using the TR342 and TR344
termination caps. These shrouds may be fi eld constructed if the dimensional requirements specifi ed in Table 1 are
maintained. Some examples are shown in Figure 4. These shrouds must be constructed from a minimum .018 in.
(26 ga) thick aluminized steel. The wire mesh is optional but recommended and must be .018 in. thick minimum
aluminized steel with a maximum 1/2 in. (13 mm) mesh opening.
- The TR-TVK Round Termination Top Vent Kit is available to reduce the minimum sizes required for shrouds. See
Table 1.

Shroud Dimensions
• Installation of the Shroud
• Center the hole in the bottom pan (if required) of the shroud over the termination cap and lower the shroud down to
the chase top.
• Be sure to keep the shroud centered over the chimney termination and fasten the shroud to the chase top with
screws.
• Be sure to caulk or seal around the screw heads to prevent leaks.
Note:
To protect against the effect of corrosion
on those parts exposed to the weather, the
termination cap can be painted with a rust-
resistant paint.
