Final answer:
The question about the clearance between a fireplace and a studded wall cannot be answered with the provided information, as it requires specific details on the fireplace type and adherence to building codes for fire safety.
Step-by-step explanation:
The clearance needed between a fireplace and a studded wall is not explicitly mentioned in the provided information. However, referring to building codes and safety regulations, the clearance typically depends on the type of fireplace and the materials used in the construction of the wall. For a wood stove or other combustion devices, the installation instructions and local building codes should be consulted for clearance requirements.
These codes often require a certain amount of non-combustible shielding between the heat source and combustible materials, including studded walls. It is imperative to adhere to these guidelines to ensure fire safety. The provided details about the construction of the exterior wall and its heat flow rate are related to insulation and thermal characteristics, which are different aspects of building physics.
