A. TR344 Round Termination Cap
• Install the roof flashing or the chase top. See Table 1 for required dimensions of the chase top if using a shroud.
• Fabricate a chase top as shown in Figure 1 or use catalog number CT35.
• The uppermost chimney section must extend 4 in. (102) above the top of the chase top collar to allow for the installation
of the termination cap and the storm collar.
Note: If you do not want to snap-lock the round termination
cap in place, crush the snap-lock tabs on the termination
cap collar flat and attach to the uppermost chimney section
with three self-tapping screws.

• Install the storm collar over the uppermost chimney section and secure in place with the provided bolt. Caulk the gaps
between the chimney and the top of the storm collar to prevent leaks. Any seams along the storm collar must also be
sealed.
• Position the round termination cap over the uppermost chimney section and snap-lock it into position.

Separation allows sparks, heat and embers
to escape.

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 flashing 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 fireplace systems using the TR342 and TR344
termination caps. These shrouds may be field constructed if the dimensional requirements specified 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.

Figure 4 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.
