How should radiant heating panels installed on wood or steel framing be positioned unless listed and labeled for field cutting?

Radiant heating panels are designed to provide efficient heating by radiating thermal energy into a space. When installed on wood or steel framing, it is crucial to position them as complete units unless they are specifically listed and labeled for field cutting. This practice helps ensure safety, optimal performance, and adherence to building codes.

Positioning radiant heating panels as complete units means that they maintain their designed thermal efficiency and electrical integrity. Field cutting can disrupt the flow of heat distribution and may introduce potential safety hazards, such as overheating or electrical failures. Therefore, if the panels are not certified for alteration, they should remain in their original state to ensure reliable and effective operation.

In contrast, the other options either imply an incomplete or fragmented setup or suggest configurations that could lead to inefficiencies or safety risks. Complete unit installations allow for the intended operational characteristics of the heating system to be met, contributing to effective and safe heating solutions in a residential or commercial environment.
