• 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

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
