WARNING Fire Risk • The minimum overlap of cap to pipe MUST be met or chimney may separate from cap. Separation allows sparks, heat and embers to escape. 2 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.

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 Storm Collar clamp lock at the top.

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. 17-1/2 in. (444 mm) Dia. centered 3-3/4 in.
