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.
