What is a requirement for servicing duct heaters?

Duct heaters must be accessible to allow for maintenance, servicing, and safety checks. Accessibility is a critical factor for ensuring that technicians can easily reach the duct heaters to perform routine inspections, cleaning, or repairs. This requirement helps to prevent safety hazards that may arise from neglect or inadequate maintenance of the heating system. Inadequate access could lead to difficulties in identifying issues, which may compromise system efficiency or lead to potential failures.

The requirement for access is foundational in mechanical design and installation guidelines to ensure that all components of the heating system function effectively and can be maintained properly. This standard upholds not just operational efficiency but also the safety of the occupants in the building.
