Evidence chain connecting site facts, classification, design basis, product evidence and approval
Jurisdiction first: classification and adopted rules come before generic product claims. Original diagram by Pergola Wiki.
Read a detailed text description

Five linked blocks run from project address and site facts to legal classification, adopted design basis, product-specific evidence and final approval or inspection records. Feedback arrows show that a mismatch in configuration, location or assumptions must be resolved rather than skipped by relying on a generic certificate.

Key takeaways

  • Do not block required openings or escape.
  • Appliance clearances come from listed instructions and local rules.
  • Roof and enclosure changes affect fire behavior.

Map regulated interfaces

Show property boundaries, nearby walls and openings, eaves, exits, bedroom windows, service equipment and neighboring structures. Fire-separation requirements are jurisdiction-specific and can depend on roof, wall, material and distance. An open frame and a roofed or screened room are not automatically equivalent.

Coordinate heat-producing equipment

Grills, fire features and radiant heaters require manufacturer-listed clearances, ventilation, fuel and electrical controls, and protection from combustible finishes. A motorized louver roof can change the overhead condition as it moves. Do not assume opening the roof makes an otherwise prohibited installation acceptable.

Protect egress and emergency access

Posts, screens, furniture, planters and control boxes should not narrow required paths or obstruct doors, windows and firefighting access. Consider operation during power failure. A closing screen or louver system should not trap occupants or conceal the manual release.

Verify after fit-out

The initial frame approval may not cover curtains, glazing, kitchens, heaters or storage added later. Maintain an as-used layout and reassess changes. Inspection should check heat damage, soot, altered clearances, blocked paths and unapproved wiring or fuel connections.
